VITOP® Capsules — Product Monograph
1. Disclaimer
This monograph is intended for educational and informational purposes only and is directed at healthcare professionals and informed consumers. It does not constitute medical advice, a prescription, or a substitute for consultation with a qualified physician or pharmacist. Product composition, labelling, indications, and regulatory status differ between countries and are subject to change by the manufacturer and by the Egyptian Drug Authority (EDA); the approved package insert supplied with the purchased pack always takes precedence over this document.
We do not guarantee the accuracy, currency or completeness of information regarding medications or medical products, and official sources should be verified before making any decisions. Readers are responsible for independently verifying the information before relying on it.
Particular caution is warranted because this brand is registered in Egypt as a combination product containing an androgen (methyltestosterone) in addition to vitamins and minerals. Androgen-containing combinations are prescription-only medicines with significant hepatic, endocrine, cardiovascular, and reproductive risks, and are not interchangeable with ordinary over-the-counter multivitamin supplements.
2. Summary
Vitop is an oral hard-gelatin capsule marketed in Egypt by Misr Co. for Pharmaceutical Industries S.A.E. In the Egyptian register it is classified as a multivitamin combination whose declared actives are methyltestosterone + vitamins + minerals + phospholipids + safflower oil. The vitamin–mineral component supplies fat-soluble vitamins (A, D2, E), the water-soluble B-complex with folic acid and biotin, ascorbic acid, the lipotropic factor inositol, calcium and phosphorus as di-calcium phosphate, iron, and the trace elements copper, zinc, manganese, iodine, and molybdenum; safflower oil and phospholipids (lecithin-type) act as lipid vehicle and lipotropic/emulsifying constituents.
It is promoted for nutritional deficiency states, convalescence and febrile illness, restricted diets, fatigue and debility, and geriatric use. Because of the androgen content, it is not a benign supplement: it is contraindicated in pregnancy, lactation, children, and in men with prostate or breast carcinoma, and it carries the hepatotoxicity, virilization, and metabolic warnings applicable to 17Ī±-alkylated androgens. The vitamin content also approaches upper intake limits for preformed vitamin A and folic acid, requiring care to avoid duplication with other supplements. Usual dosing is one capsule daily with food, under medical supervision.
3. Brand Name
Vitop® Capsules. Marketed in Egypt in a 30-capsule pack (3 strips × 10 capsules); a 10-capsule presentation has also been registered, and larger dispensing packs of 100 capsules (10 strips × 10) have appeared on manufacturer labelling. Brand names, pack sizes, and formulations may differ or be discontinued in other markets.
4. Category
Pharmacotherapeutic class: multivitamin and multimineral preparation in fixed-dose combination with an anabolic-androgenic steroid and lipotropic agents — a "tonic/restorative" combination product.
ATC classification: closest matches are A11A (multivitamins, combinations) and G03B / A14A (androgens, anabolic steroids) for the methyltestosterone component.
Legal status in Egypt: prescription medicine, on account of the androgen content. Internationally, methyltestosterone is a controlled substance (Schedule III in the United States) and is prohibited in sport (WADA class S1).
5. Active Ingredient
The Egyptian marketing authorization lists the actives as methyltestosterone, vitamins, minerals, phospholipids, and safflower oil. The strength of the methyltestosterone component is stated on the manufacturer's package insert enclosed in the pack currently on sale, and must be read from that insert; it is not reproducible from publicly accessible sources. No published figure for this component should be assumed, and prescribers requiring the exact strength should confirm it with the manufacturer's scientific office or the EDA registration record.
Vitamin and mineral content as declared by the manufacturer. The figures below reproduce a manufacturer composition statement for this brand. Reformulation is possible and the constituent list associated with the current Egyptian registration is broader than the table shown; readers must therefore check these figures against the insert supplied with the pack in hand rather than relying on the table alone.

6. Pharmaceutical Form & Strength
Oral hard-gelatin capsule with an oil-based or semi-solid fill. Currently marketed in Egypt as a 30-capsule pack, with a 10-capsule presentation also registered. A single strength only is available; the capsule is neither scored nor divisible, so dose reduction is not possible and any individualization of the androgen dose is impracticable with this product. Supplied in blister strips of 10 capsules within a printed carton containing the manufacturer's insert.
7. Manufacturer & Marketing Authorization Holder
Misr Co. for Pharmaceutical Industries S.A.E. (MISR), Cairo, Arab Republic of Egypt, acting as both manufacturer and marketing authorization holder. The product carries an Egyptian registration number and has undergone local re-registration. The pack also bears the standard consumer-safety advisory of the Council of Arab Health Ministers and the Union of Arab Pharmacists. Batch number, manufacturing date, and expiry date are printed on the carton and on each strip.
8. Mechanism of Action
The preparation acts through several independent mechanisms rather than a single pharmacological target.
Nutrient replacement. The vitamins act as coenzymes or coenzyme precursors: thiamine as thiamine pyrophosphate in oxidative decarboxylation; riboflavin as FAD and FMN and nicotinamide as NAD and NADP in redox reactions and ATP generation; pantothenate as coenzyme A in fatty-acid and Krebs-cycle metabolism; pyridoxine as pyridoxal-5-phosphate in transamination and heme synthesis; folate and B12 as one-carbon donors for thymidylate and methionine synthesis and thus for DNA replication and erythropoiesis; biotin as a carboxylase cofactor. Ascorbic acid is a water-soluble antioxidant and cofactor for collagen hydroxylation, and it enhances non-heme iron absorption. Vitamin A supports rhodopsin formation, epithelial differentiation, and immune competence through nuclear RAR and RXR receptors. Vitamin D2 is hydroxylated to 25-hydroxyvitamin D and then to 1,25-dihydroxyvitamin D, a hormone regulating intestinal calcium and phosphate absorption and bone mineralization. Vitamin E is a chain-breaking, lipid-phase antioxidant protecting membrane polyunsaturated fatty acids.
Mineral and trace-element repletion. Iron is incorporated into haemoglobin, myoglobin, and cytochromes; calcium and phosphorus into hydroxyapatite; zinc, copper, manganese, and molybdenum serve as metalloenzyme cofactors, for example in carbonic anhydrase, superoxide dismutase, arginase, and xanthine oxidase; iodine is the substrate for thyroxine and triiodothyronine synthesis.
Lipotropic action. Inositol and phospholipids such as phosphatidylcholine contribute to membrane structure, inositol-phosphate signalling, and hepatic lipoprotein assembly and export, which is the traditional basis of the claim that these agents reduce hepatic fat accumulation. Safflower oil supplies linoleic acid, an essential omega-6 fatty acid and precursor of arachidonic acid, and aids dissolution and absorption of the fat-soluble vitamins.
Androgenic and anabolic action. Methyltestosterone is a 17Ī±-methylated derivative of testosterone that binds the cytoplasmic androgen receptor; the receptor–ligand complex translocates to the nucleus and modulates transcription of androgen-responsive genes, producing nitrogen retention, increased protein anabolism, stimulation of erythropoiesis through erythropoietin and improved iron utilization, and development or maintenance of male secondary sexual characteristics. Unlike testosterone it is a poor substrate for 5Ī±-reductase, but it is aromatized to 17Ī±-methylestradiol, which accounts for part of its oestrogenic adverse effects such as gynecomastia. The 17Ī±-methyl group confers oral activity but also the hepatotoxic potential characteristic of this chemical class.
9. Spectrum of Activity
Not applicable in the microbiological sense — Vitop has no antibacterial, antiviral, antifungal, or antiparasitic activity and must never be used to treat infection. Its spectrum is metabolic and nutritional: it covers the fat-soluble and water-soluble vitamin groups, with the notable omission of vitamin K, together with essential trace elements and an androgenic anabolic effect. Despite the presence of sulfate salts, it does not provide clinically meaningful electrolyte replacement.
10. Pharmacokinetics
Water-soluble vitamins (B-complex, vitamin C) are absorbed mainly in the proximal small intestine by saturable carrier-mediated transport at physiological doses and by passive diffusion at high doses. They distribute widely, are minimally protein-bound apart from riboflavin and B12, undergo limited storage — except B12, which is stored in the liver for years and requires intrinsic factor and gastric acid for absorption — and are excreted renally, with excess appearing unchanged in urine. Folic acid is reduced to tetrahydrofolate and enters the enterohepatic circulation; oral folic acid at 1 mg is almost completely bioavailable.
Fat-soluble vitamins require bile salts, pancreatic lipase, and dietary fat for micellar absorption, are transported in chylomicrons through the lymphatics, and accumulate in the liver — vitamin A as retinyl esters in stellate cells — and in adipose tissue. Their long half-lives and hepatic storage create genuine cumulative toxicity potential with chronic high intake. Ergocalciferol is hydroxylated in the liver and kidney and eliminated in bile. The oil-based fill favours absorption when the capsule is taken with a meal.
Minerals. Iron absorption occurs in the duodenum and is hepcidin-regulated, typically 5–15% of an oral dose, enhanced by ascorbic acid and reduced by calcium, phytates, tannins, and antacids; it is transported bound to transferrin, stored as ferritin, and has no significant excretory route. Calcium absorption is vitamin D-dependent and dose-dependent, in the region of 25–35% at these amounts. Zinc and copper share intestinal transport pathways and compete with one another; iodine is rapidly and almost completely absorbed and concentrated by the thyroid; molybdenum and manganese are absorbed to a limited degree and excreted mainly in bile.
Methyltestosterone is well absorbed orally and, because the 17Ī±-methyl group resists hepatic 17Ī²-hydroxysteroid dehydrogenase, it escapes extensive first-pass inactivation, giving oral bioavailability of roughly 70%. It is highly protein-bound to albumin and sex hormone-binding globulin, has a short plasma elimination half-life of approximately 2.5–4 hours, is hepatically metabolized including aromatization to 17Ī±-methylestradiol followed by conjugation, and is excreted predominantly in urine as glucuronide and sulfate conjugates with a small biliary and faecal fraction. Buccal administration, which does not apply to this capsule, approximately doubles potency.
11. Indications
As labelled and as conventionally used for this class of combination:
- Prevention and correction of vitamin and mineral deficiency states where dietary intake is inadequate or requirements are increased.
- Convalescence after acute illness, surgery, or febrile disease, when appetite and intake are reduced and catabolism increased.
- Patients on restricted, monotonous, or reducing diets, and adjunctive supplementation in malabsorption states, chronic alcohol use, and post-bariatric or post-gastrectomy patients.
- Old age and geriatric debility with poor nutritional intake.
- Fatigue, weakness, and loss of appetite attributed to nutritional depletion.
- Adjunct in male hypoandrogenic states accompanied by nutritional depletion — this reflects the methyltestosterone component and is the principal reason the product requires medical supervision.
An important limitation should be stated plainly. Fixed-dose combinations of nutrients with an androgen are widely regarded by contemporary regulators and clinical pharmacologists as pharmacologically irrational for routine tonic use, because the two components have unrelated indications and the androgen exposes patients who have no androgen deficiency to avoidable hormonal risk. Where the objective is purely nutritional, a plain multivitamin–mineral product is preferable; where genuine hypogonadism exists, it should be confirmed biochemically and treated with a dedicated, dose-titratable androgen preparation. Vitop is not indicated for anaemia of undetermined cause, for weight gain in children, for athletic performance, or for the treatment of any infection.
12. Administration
Adults: one capsule daily, or as directed by the physician. Labelling that permits "one capsule or more daily" should not be read by patients as licence to self-escalate; higher intakes increase the risk of preformed vitamin A toxicity and of androgen-related adverse effects, and any dose above one capsule daily should be physician-directed and time-limited.
Swallow the capsule whole with a full glass of water, preferably with or immediately after a meal containing some fat, which improves absorption of vitamins A, D, and E and reduces the gastric irritation and nausea associated with ferrous sulfate. Do not chew, open, or dissolve the capsule. Separate administration by at least two to four hours from tetracyclines, fluoroquinolones, levothyroxine, bisphosphonates, penicillamine, and antacids. Courses should be defined and reviewed rather than continued indefinitely; a typical review point is four to twelve weeks, with liver function testing and, in men over 45, prostate assessment considered if therapy is prolonged. A missed dose may simply be taken later the same day, and doses must never be doubled. Harmless yellow discolouration of urine from riboflavin and darkening of the stools from iron should be expected.
13. Method of Preparation
No preparation, reconstitution, dilution, or admixture is required; the product is a ready-to-use solid oral dosage form. Dispense in the original blister and do not repackage oil-filled capsules into multi-dose pill organizers, since heat, humidity, and light accelerate oxidation of the fat-soluble vitamins and of the safflower oil. Because the capsule cannot be divided and the fill is an oil-based suspension, it is unsuitable for extemporaneous compounding, for nasogastric or enteral-tube administration, and for paediatric dose adjustment; an alternative liquid nutrient preparation without an androgen should be used in those situations. Handling by pharmacy staff requires no special precautions beyond routine good dispensing practice.
14. Contraindications
- Known hypersensitivity to any vitamin, mineral, dye, gelatin, safflower or other Asteraceae-family plants, soy- or egg-derived phospholipids, or any other excipient.
- Pregnancy, and women who may become pregnant — absolute. Methyltestosterone is an established teratogen causing virilization of a female fetus, and preformed vitamin A at 10,000 IU per capsule adds an independent teratogenic risk.
- Breastfeeding.
- Carcinoma of the prostate or male breast carcinoma, and benign prostatic hyperplasia with obstructive symptoms.
- Severe hepatic impairment, cholestasis, or active liver disease; severe renal impairment; decompensated cardiac failure or nephrotic syndrome, because of fluid retention.
- Children and adolescents, in whom androgens cause premature epiphyseal closure and precocious virilization; the vitamin A, folic acid, and iron content is likewise unsuitable for paediatric dosing.
- Hypervitaminosis A or D, hypercalcaemia, hypercalciuria, hyperphosphataemia, nephrolithiasis, or sarcoidosis.
- Iron-overload states including haemochromatosis, haemosiderosis, iron-loaded thalassaemia, and sideroblastic anaemia, and transfusion dependence.
- Wilson's disease and other copper-storage disorders, given the copper content.
- Untreated pernicious anaemia or untreated megaloblastic anaemia of unknown cause, because 1 mg of folic acid can correct the anaemia while allowing irreversible neurological progression of B12 deficiency; the 1 Āµg of B12 present is far too small to protect against this.
- Concurrent use of a systemic retinoid or of any other vitamin A-containing supplement.
15. Warnings & Precautions
Androgen-related. The 17Ī±-alkylated androgens are associated with peliosis hepatis, hepatic adenoma and rarely hepatocellular carcinoma, cholestatic hepatitis and jaundice, and elevated transaminases; these lesions may remain silent until life-threatening intra-abdominal haemorrhage occurs. Discontinue and investigate promptly in the event of jaundice, dark urine, pale stools, right upper quadrant pain, or unexplained pruritus. Androgens can cause sodium and water retention with oedema and worsening of hypertension, heart failure, or renal disease; they raise LDL and lower HDL cholesterol; and they may increase haematocrit with a consequent thrombotic risk. In women, virilization — deepening of the voice, hirsutism, acne, clitoromegaly, menstrual irregularity, and androgenic alopecia — may be irreversible. In men, possible effects include gynecomastia, oligospermia with reduced fertility, testicular atrophy with prolonged use, priapism, which is a urological emergency, and, in older men, unmasking or acceleration of prostatic hypertrophy or carcinoma; baseline and periodic prostate examination with PSA measurement is advisable in men over 45 receiving prolonged therapy. Mood change, irritability, aggression, and sleep disturbance can occur. The abuse potential of this class is well recognized: the product must not be used for muscle building or athletic enhancement and will produce a positive doping test.
Vitamin-related. Each capsule delivers preformed vitamin A at approximately the adult tolerable upper intake level, so concurrent use of cod-liver oil, other multivitamins, or systemic retinoids risks chronic hypervitaminosis A, which manifests as headache, raised intracranial pressure, bone and joint pain, dry skin and lips, hair loss, hepatotoxicity, and reduced bone mineral density. Folic acid at 1 mg likewise sits at the upper limit and can mask B12 deficiency and interfere with anticonvulsant control. Vitamin D2 at 1,000 IU is generally safe but adds to other vitamin D sources and, together with the calcium content, warrants monitoring of serum calcium in patients with renal impairment, hyperparathyroidism, or granulomatous disease. Long-term high-dose pyridoxine is neurotoxic, although the 0.5 mg present here is in fact below typical daily requirements and should not be relied upon to treat B6 deficiency.
Adequacy limitations. Several constituents are present only in token amounts — B12 at 1 Āµg, pyridoxine at 0.5 mg, zinc at 1.2 mg, magnesium at 6 mg, potassium at 5 mg, biotin at 15 Āµg, and vitamin E at 5 mg — and will not correct established deficiency of those nutrients. Iron at 10 mg is a supplemental rather than a therapeutic dose and is inadequate for treating iron-deficiency anaemia, which requires substantially higher elemental iron intake. This product should not be substituted for specific deficiency treatment or for a balanced diet.
General. The capsule shell contains gelatin of animal origin, which is relevant to religious and vegetarian dietary requirements. Accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under six, so the pack must be kept out of reach of children. High-dose vitamin C may increase oxalate excretion in stone formers, and ascorbic acid, iron, and biotin can interfere with certain laboratory assays, including some troponin and thyroid immunoassays — the laboratory should be informed. Androgens may alter thyroid function tests by lowering thyroxine-binding globulin and may produce abnormal glucose tolerance results. Discontinue and seek advice if rash, facial or throat swelling, or breathing difficulty occurs.
16. Drug Interactions
Absorption and chelation. The iron, calcium, zinc, magnesium, and manganese content reduces absorption of tetracyclines and doxycycline, fluoroquinolones such as ciprofloxacin, levofloxacin, and moxifloxacin, levothyroxine, oral bisphosphonates, penicillamine, methyldopa, mycophenolate, integrase inhibitors such as dolutegravir, and some cephalosporins; separate doses by at least two to four hours. Conversely, proton-pump inhibitors, H2 antagonists, antacids, tetracyclines, and the bile-acid sequestrants cholestyramine and colestipol reduce absorption of iron and of the fat-soluble vitamins, while orlistat and mineral oil reduce absorption of vitamins A, D, E, and K.
Methyltestosterone. Potentiation of warfarin and other coumarin anticoagulants may cause a marked rise in INR with bleeding risk, and anticoagulant dose reduction with frequent monitoring is mandatory. The hypoglycaemic effect of insulin, sulfonylureas, and other antidiabetic agents is enhanced, requiring dose review. Fluid retention is additive with corticosteroids, ACTH, and NSAIDs. Cyclosporine and possibly tacrolimus concentrations may rise, with nephrotoxicity risk. Hepatotoxicity may be additive with paracetamol in overdose, isoniazid, methotrexate, amiodarone, statins, azole antifungals, and alcohol. CYP3A4 inhibitors and inducers may alter methyltestosterone exposure. Androgens antagonize oestrogens, GnRH analogues, and antiandrogens such as bicalutamide and finasteride, and interfere with interpretation of testosterone and gonadotropin assays.
Vitamins. Vitamin A is additive with acitretin, isotretinoin, and bexarotene, producing severe hypervitaminosis A, and with tetracyclines it raises the risk of benign intracranial hypertension. Folic acid lowers serum phenytoin, phenobarbital, and primidone concentrations with possible loss of seizure control, and is antagonized by methotrexate, trimethoprim, sulfasalazine, pyrimethamine, and triamterene. Pyridoxine reduces the efficacy of levodopa given without a peripheral decarboxylase inhibitor and antagonizes phenytoin and phenobarbital, while isoniazid, hydralazine, cycloserine, and penicillamine deplete B6. Vitamin D effects are increased by thiazide diuretics with a risk of hypercalcaemia and reduced by phenytoin, rifampicin, and glucocorticoids; resulting hypercalcaemia potentiates digoxin toxicity and antagonizes calcium-channel blockers. Vitamin E in large doses may add to the effect of warfarin and antiplatelet agents. Potassium iodide may cause additive hypothyroidism with lithium, amiodarone, or antithyroid drugs. Vitamin C markedly increases non-heme iron absorption, which is beneficial here but relevant in iron-loading disorders, and high doses may alter urinary pH.
17. Side Effects
Common and generally mild: nausea, epigastric discomfort, heartburn, metallic taste, abdominal cramping, constipation or diarrhoea, and black stools from iron; bright yellow urine from riboflavin; mild headache; and unpleasant aftertaste or belching from the oil-based fill.
Androgen-attributable: acne, oily skin, increased body and facial hair, fluid retention with weight gain and ankle oedema, hypertension, mood swings, insomnia, change in libido, gynecomastia and breast tenderness in men, reduced sperm count, priapism or persistent unwanted erections, testicular atrophy with prolonged use, and in women hirsutism, voice deepening, menstrual disturbance, amenorrhoea, clitoral enlargement, and androgenic alopecia — several of which are irreversible. Adverse lipid changes, polycythaemia, and altered clotting factors may be detected on testing rather than symptomatically.
Serious but uncommon to rare: cholestatic jaundice and hepatitis, transaminase elevation, peliosis hepatis, and hepatic adenoma or carcinoma with long-term use; worsening of heart failure; thromboembolism secondary to erythrocytosis; hypercalcaemia; hypersensitivity reactions ranging from urticaria to anaphylaxis; benign intracranial hypertension and other features of hypervitaminosis A with chronic excessive intake; and hypervitaminosis D with hypercalcaemia, polyuria, nephrocalcinosis, and renal impairment.
Patients should stop the capsule and seek medical attention for yellowing of the eyes or skin, dark urine, severe or persistent abdominal pain, unexplained bruising or bleeding, prolonged erection, sudden breathlessness or leg swelling, severe headache with visual disturbance, or any sign of allergy. Suspected adverse reactions should be reported to the Egyptian Pharmacovigilance Center of the EDA.
18. Use in Special Populations
Pregnancy: contraindicated. Methyltestosterone virilizes the female fetus, and preformed vitamin A above 10,000 IU daily is associated with craniofacial and central nervous system malformations. Women of childbearing potential should use effective contraception, and pregnancy should be excluded before initiation. Pregnant women requiring supplementation should receive a purpose-designed prenatal preparation with beta-carotene or low retinol content, appropriate folic acid, and no androgen.
Lactation: contraindicated. Androgens pass into breast milk, may suppress lactation, and pose a virilization risk to the infant.
Children and adolescents: not recommended at any age. Androgens cause premature epiphyseal closure with permanent loss of adult height, precocious puberty, and priapism, and the vitamin A, folic acid, and iron content is unsuitable for paediatric dosing. Accidental ingestion by a child is a medical emergency because of the iron and vitamin A content, and a poison centre should be contacted immediately.
Elderly: the nutritional component is often appropriate, but androgen exposure in older men increases the risk of prostatic hypertrophy, prostate cancer progression, fluid retention, and cardiovascular events. If used, keep the course short and monitor blood pressure, haematocrit, liver enzymes, lipids, and prostate status; a plain multivitamin is often the better choice. Reduced renal function increases sensitivity to the calcium and vitamin D content.
Hepatic impairment: avoid, since 17Ī±-alkylated androgens are directly hepatotoxic and clearance is impaired.
Renal impairment: use with caution or avoid, given the risk of fluid retention, hypercalcaemia, hyperphosphataemia, and accumulation of magnesium, potassium, and trace elements in advanced disease. Dialysis patients require nephrology-specific vitamin preparations.
Cardiac disease, hypertension, epilepsy, diabetes, and thyroid disease: use only under supervision with the monitoring outlined above.
Athletes: prohibited, as the product contains an anabolic androgenic steroid included on the WADA prohibited list at all times.
19. Storage Conditions
Store below 30 °C in a dry place, protected from light, heat, and moisture; do not refrigerate or freeze. Keep in the original blister and carton until the moment of use, since oil-filled capsules soften, leak, and undergo oxidative rancidity when exposed to heat or humidity, and the fat-soluble vitamins degrade on light exposure. Avoid storage in bathrooms, cars, or on windowsills. Keep out of the sight and reach of children, as iron-containing products are a common cause of serious paediatric poisoning. Do not use beyond the printed expiry date, or if capsules are discoloured, stuck together, leaking, softened, or have an unusual rancid odour. Dispose of unused or expired capsules through a pharmacy take-back scheme rather than in household waste or wastewater.
20. Additional Sections
Overdose. Acute overdose is most dangerous because of the iron and vitamin A content. Iron poisoning progresses through vomiting and haematemesis, diarrhoea, and abdominal pain, followed by an apparent latent recovery phase and then metabolic acidosis, hepatic necrosis, shock, coagulopathy, and late gastric scarring; management requires urgent hospital assessment, serum iron measurement, supportive care, and deferoxamine chelation where indicated. Acute vitamin A overdose causes headache, vomiting, drowsiness, vertigo, raised intracranial pressure, and later skin desquamation. Massive ingestion of vitamin D with calcium may produce hypercalcaemia. Androgen overdose is unlikely to be acutely fatal but may cause priapism and oedema. No specific antidote exists for the combination; treatment is supportive, with priority given to iron toxicity. The pack should be brought to hospital.
Regulatory context. Fixed-dose combinations pairing vitamins with anabolic-androgenic steroids have been withdrawn or restricted in several jurisdictions on grounds of therapeutic irrationality and hormonal risk, and methyltestosterone as a single agent has largely been superseded by transdermal, injectable, and oral testosterone undecanoate formulations that are less hepatotoxic and easier to titrate. Prescribers should therefore have a clear, documented reason for selecting this combination in preference to separate products.
Practical counselling points. Take with food; expect dark stools and yellow urine; avoid taking a second multivitamin, cod-liver oil, or a retinoid concurrently; report jaundice, oedema, prolonged erection, or voice change immediately; women must avoid the product if pregnancy is possible; keep the pack away from children; and review the need for continuation with a doctor rather than repeating the prescription indefinitely.
Cost and availability. Marketed in Egypt as an inexpensive small-pack product. Retail prices quoted on pricing websites are frequently outdated, and current price, pack size, and availability should be confirmed with a pharmacy or against the EDA price list.
21. Frequently Asked Questions (FAQ)
Is Vitop simply an ordinary multivitamin?
No. In Egypt it is registered as a combination containing methyltestosterone, a synthetic male hormone, alongside vitamins, minerals, phospholipids, and safflower oil. That makes it a prescription medicine with hormonal risks rather than a routine over-the-counter supplement.
Can a woman take it?
Only if a physician has specifically prescribed it and pregnancy has been excluded, and even then with caution. Androgenic effects such as facial hair growth, acne, voice deepening, and menstrual disturbance can be permanent. It must never be taken during pregnancy or breastfeeding.
Can children take it for poor appetite or growth?
No. Androgens can permanently stunt growth by closing the epiphyseal plates early, and the vitamin A, folic acid, and iron amounts are not designed for children. A paediatrician should advise on appropriate supplementation.
Will it treat anaemia?
Not adequately. Ten milligrams of elemental iron is a maintenance rather than a treatment dose, and 1 Āµg of vitamin B12 is far below what B12 deficiency requires. More importantly, the 1 mg of folic acid can partially correct the blood picture of B12 deficiency while nerve damage continues unchecked. Anaemia needs proper diagnosis and targeted treatment.
How long can it be taken?
It is intended for defined courses rather than indefinite use. Prolonged androgen exposure risks liver injury, adverse cholesterol changes, and prostate problems, while chronic high preformed vitamin A intake harms the liver and bones. The need for continuation should be reviewed after a few weeks.
Can it be used to build muscle or improve sports performance?
No. That is misuse of an anabolic steroid, it carries real hepatic, cardiovascular, and fertility risks, and it will produce a positive anti-doping result.
What should prompt immediate discontinuation?
Yellowing of the eyes or skin, dark urine, severe abdominal pain, unusual bruising or bleeding, sudden swelling or breathlessness, severe headache with blurred vision, a prolonged painful erection, or any rash or facial swelling.
