This drug commentary is intended for educational and informational purposes only. It does not replace the official product information, package insert, prescribing information, or individualized advice from a qualified physician or pharmacist. Because formulations, excipients, approved indications, labeling, manufacturers, and regulatory status may vary between countries and between products with similar names, the actual package label should always be checked before use.
1. Summary
Calamine 15% Lotion 120 mL is a topical suspension containing calamine and zinc oxide, used primarily as a soothing, protective, mildly astringent and antipruritic preparation for minor skin irritation and itching.
The formulation supplied in the older product information states that each 100 mL contains:
- Calamine: 15 g (15%)
- Zinc oxide: 5 g (5%)
This composition corresponds to the traditional British Pharmacopoeia (BP)-type calamine lotion formulation. The BP formulation traditionally also includes excipients such as bentonite, sodium citrate, glycerol and, in some formulations, liquefied phenol. However, the exact excipient composition of the currently marketed Egyptian product should be confirmed from its current package insert because marketed products can differ from pharmacopoeial formulations.
Calamine lotion acts mainly at the skin surface. It does not function as a corticosteroid, antihistamine, antibiotic, antifungal, or systemic anti-inflammatory drug. Its principal role is symptomatic relief rather than treatment of the underlying cause of a dermatological disease.
2. Brand Name
Calamine 15% Lotion 120 mL
The product is listed in current Egyptian drug databases as:
Calamine 15% lotion 120 ml
Current public Egyptian listings identify Philo Pharm Pharmaceuticals as the manufacturer/producer.
Other calamine products mentioned in the supplied information
The following products should not automatically be considered interchangeable with Calamine 15% Lotion because their compositions and manufacturers may differ:
- Calamine Baby Pinny Bunny — calamine + zinc oxide + chamomile; listed as an emollient/cosmetic product — Nile for Cosmetic → Marketova.
- Calamine Go Lotion 120 mL — calamine + zinc oxide + glycerin; listed as a soothing topical product — El Helou for Perfumes & Cosmetics (Healthy Group) → Biophar Pharmaceutical.
- Calamine Lotion 100 mL Novex — calamine + zinc oxide; listed under PHARCO.
- Calamine Plus Lotion 125 mL — soothing topical product — Philo Pharm Pharmaceuticals.
These products should be evaluated according to their individual current labels, rather than assuming that all calamine lotions have the same formulation, indications, or precautions.
3. Category
Pharmacological/therapeutic category:
- Topical skin protectant
- Soothing topical preparation
- Mild astringent
- Antipruritic preparation
- Protective/drying lotion
Calamine is generally regarded as a topical skin protectant/antipruritic rather than a conventional anti-inflammatory drug. Current U.S. OTC labeling, for example, classifies calamine/zinc oxide products as skin protectants.
4. Active Ingredients
Calamine — 15%
Calamine is a traditional topical preparation containing zinc compounds and ferric oxide pigment. Its characteristic pink color is produced by iron oxide.
Zinc oxide — 5%
Zinc oxide contributes protective, mildly astringent and soothing properties.
The traditional BP formulation contains 15 g calamine + 5 g zinc oxide per 100 mL.
Important formulation note
There is no single universal calamine-lotion composition.
For example:
- Traditional BP-type formulation: Calamine 15% + Zinc oxide 5%
- USP-type formulation: Calamine 8% + Zinc oxide 8%
Therefore, the concentration written on the package should always be checked rather than assuming that every "calamine lotion" contains 15% calamine.
5. Pharmaceutical Form & Strength
Dosage form: Topical lotion/suspension
Pack size: 120 mL
Strength stated for the product:
- Calamine 15 g/100 mL
- Zinc oxide 5 g/100 mL
The preparation is a suspension rather than a true molecular solution. Therefore, shaking the bottle thoroughly before application is important to redistribute suspended particles uniformly.
6. Manufacturer & Marketing Authorization Holder
Manufacturer
Current publicly available Egyptian drug listings identify:
Philo Pharm Pharmaceuticals
as the producer/manufacturer of Calamine 15% Lotion 120 mL.
Marketing Authorization Holder
A currently verifiable official regulatory source confirming the exact Marketing Authorization Holder (MAH) for the present formulation was not identified in the accessible public sources reviewed.
Therefore, the MAH should not be assumed to be the same as the manufacturer.
Important correction concerning the supplied old leaflet
The older information supplied with this request states:
"PRODUCED BY PHARCO Pharmaceuticals, ALEXANDRIA"
and describes a 120-mL product containing calamine 15 g and zinc oxide 5 g per 100 mL.
However, current Egyptian listings identify Philo Pharm Pharmaceuticals for the product specifically named Calamine 15% Lotion 120 mL.
Consequently, the older Pharco statement should be treated as historical/product-specific information rather than definitive evidence about the current Philo Pharm product.
7. Mechanism of Action
Calamine lotion produces mainly local physical and physicochemical effects on the skin surface.
Calamine
Calamine has a mild astringent effect, which can help reduce superficial irritation and exudation and produce a soothing/drying effect.
Zinc oxide
Zinc oxide provides:
- Mild astringent activity
- Protective/barrier effects
- Soothing effects
- Mild antiseptic properties
The combination therefore helps create a superficial protective layer and may reduce irritation and itching.
Antipruritic effect
Its antipruritic effect is primarily symptomatic and superficial. It does not block histamine H1 receptors like antihistamines and does not suppress inflammation through glucocorticoid receptors like corticosteroids.
Calamine lotion therefore should not be regarded as a substitute for:
- Topical corticosteroids when indicated
- Antihistamines when systemic antihistamine therapy is required
- Antimicrobials when infection is present
- Antifungal treatment when dermatophyte/candidal infection is present
- Specific therapy for an underlying inflammatory or autoimmune disorder
8. Spectrum of Activity
Not applicable in the conventional antimicrobial sense.
Calamine lotion is not an antibiotic, antifungal, antiviral, or antiparasitic medication.
Although zinc oxide has mild antiseptic/antimicrobial properties, this should not be interpreted as clinically adequate treatment for established bacterial, fungal, viral, or parasitic infections. The principal therapeutic purpose of calamine lotion is skin protection, soothing, drying and symptomatic relief of itching/irritation.
9. Pharmacokinetics
Calamine lotion is a topical preparation with predominantly local action.
Detailed human pharmacokinetic data for topical calamine are limited, and a standard systemic pharmacokinetic profile has not been established. A UK product SmPC specifically reports that pharmacokinetic information for calamine lotion is unavailable.
Because the preparation primarily remains on the skin surface and is poorly suited to systemic absorption, clinically significant systemic exposure is generally expected to be low when used appropriately on intact skin.
However, systemic exposure can theoretically increase when topical preparations are:
- Applied to very large body-surface areas
- Applied repeatedly or excessively
- Applied to damaged/eroded skin
- Used under occlusion
- Used in very young children
- Used in formulations containing additional potentially absorbable ingredients
The safety profile therefore depends not only on "calamine" itself but also on the complete formulation.
10. Indications
Calamine lotion may be used for symptomatic relief of mild itching and minor skin irritation.
The supplied historical product information lists:
- Mild skin inflammation with redness
- Urticaria
- Prickly heat/miliaria
- Mild sunburn
These uses are consistent with the general role of calamine as a soothing and antipruritic topical preparation.
Depending on the formulation and local labeling, calamine preparations may also be used for symptomatic relief associated with:
- Minor skin irritation
- Insect bites and stings
- Irritant rashes
- Superficial itching
- Certain contact reactions
- Oozing/weeping superficial dermatitis
- Poison ivy/oak/sumac reactions in countries where such indications are labeled
Current U.S. OTC labels specifically describe calamine/zinc oxide preparations as skin protectants that can temporarily relieve itching and help dry oozing/weeping from poison ivy, poison oak and poison sumac. Some current products also include insect bites and minor skin irritations among their labeled uses.
Important clinical limitation
Calamine treats symptoms, not necessarily the underlying disease.
For example, persistent pruritus caused by:
- Scabies
- Tinea
- Bacterial infection
- Atopic dermatitis
- Allergic contact dermatitis
- Drug eruption
- Urticaria
- Systemic disease
may require disease-specific treatment.
11. Administration
Route
Topical/cutaneous use only.
Administration instructions
For the formulation described in the supplied product information:
- Shake well before use.
- Apply a thin layer to the affected skin.
- Spread gently over the affected area.
- The historical product information recommends application 3–4 times daily.
Current calamine OTC labeling varies between products; some labels state application "as needed," while others specify up to 3–4 applications daily. Therefore, the current package insert for the particular product should take precedence.
Application technique
Avoid vigorous rubbing, particularly when the skin is inflamed or irritated.
Because calamine dries on the skin and may leave a visible pink/white residue, patients should be advised that this is an expected characteristic of the preparation.
12. Method of Preparation
The exact manufacturing process of the current commercial Philo Pharm product should be obtained from the manufacturer's current pharmaceutical documentation and should not be inferred solely from a historical leaflet.
However, pharmacopoeial calamine lotions are suspensions.
The traditional BP formulation contains:
- Calamine
- Zinc oxide
- Bentonite
- Sodium citrate
- Glycerol
- Water
- Historically, liquefied phenol in the BP formulation
The BP preparation uses the powder ingredients and a suspension vehicle to produce a topical shake lotion. The USP formulation differs and uses bentonite magma and calcium hydroxide solution.
Practical point
Because the insoluble ingredients settle during storage, shaking before use is essential.
13. Contraindications
Absolute contraindications are limited for simple calamine/zinc oxide preparations.
The principal contraindication is:
Hypersensitivity
Do not use in patients with known hypersensitivity to:
- Calamine
- Zinc oxide
- Or any component/excipient of the particular formulation.
Avoid inappropriate application
The preparation should not routinely be applied:
- Into the eyes
- Onto mucous membranes
- Into the mouth
- Internally
- To large areas of severely damaged skin unless specifically directed by a healthcare professional
The current labeling of calamine/zinc oxide products consistently emphasizes external use only and avoidance of ocular exposure.
14. Warnings & Precautions
External use only
Calamine lotion is intended for cutaneous application only.
Eyes
Avoid contact with the eyes.
If accidental ocular exposure occurs, rinse thoroughly with clean water. Persistent irritation warrants medical assessment.
Mucous membranes
Avoid application to mucous membranes unless specifically directed by a healthcare professional.
Broken or severely damaged skin
The historical product information specifically recommends application to intact skin.
Although calamine is commonly used for superficial irritated skin, caution is appropriate when the epidermal barrier is extensively disrupted.
Large areas
Avoid unnecessary application over very extensive body-surface areas without medical advice.
Children
Pediatric use depends on the exact formulation.
Some current OTC calamine/zinc oxide labels specifically advise consulting a doctor before use in children younger than 2 years.
This precaution should not automatically be generalized to every calamine formulation because labeling differs by product and jurisdiction.
Persistence or worsening of symptoms
Medical evaluation is recommended if:
- The condition becomes worse.
- Symptoms persist beyond approximately 7 days.
- Symptoms improve and then recur within a few days.
These warnings appear in current U.S. calamine product labeling.
Do not mistake symptom relief for disease control
Temporary improvement in itching does not establish the diagnosis or indicate that the underlying disease has resolved.
15. Drug Interactions
Clinically significant systemic drug interactions
For a simple topical calamine/zinc oxide lotion applied appropriately to intact skin, clinically significant systemic drug interactions are unlikely because systemic absorption is expected to be minimal.
Topical interactions
The more relevant issue is concurrent use with other topical products on the same area.
Applying multiple preparations simultaneously may:
- Dilute or interfere with the action of either product.
- Alter the pH or physical characteristics of the other preparation.
- Produce a residue that interferes with the absorption of another topical drug.
Therefore, it is generally preferable to space the application of different topical products or consult a healthcare professional for guidance.
16. Side Effects
Calamine lotion is generally well tolerated when used appropriately on intact skin.
Possible adverse effects include:
- Local skin irritation or sensitivity reactions.
- Hypersensitivity reactions (e.g., rash, itching, swelling).
- Excessive skin dryness with prolonged or excessive use.
If severe skin irritation or a hypersensitivity reaction occurs, the product should be discontinued and the area washed thoroughly.
17. Use in Special Populations
Pregnancy
Simple topical calamine/zinc oxide lotion is generally considered low risk when used appropriately on limited areas because systemic absorption is expected to be minimal. However, patients should consult a healthcare professional before use, particularly if the formulation contains additional active ingredients.
Lactation
Simple topical calamine/zinc oxide preparations are generally expected to be compatible with breastfeeding. Avoid applying the product to the breast or nipple area immediately before feeding to prevent accidental ingestion by the infant.
Pediatrics
Check the specific product labeling for age restrictions. Some products advise consulting a physician before use in children younger than 2 years.
Elderly
No specific age-related dose adjustment is generally required for simple topical calamine lotion.
18. Storage Conditions
The supplied Egyptian product information states:
- Store at temperature not exceeding 30°C.
- Keep the container tightly closed.
- Keep out of reach of children.
Because storage requirements may vary by manufacturer, the **instructions on the actual current package should be considered definitive**.
19. Clinical Use: What Calamine Lotion Does Well
Calamine is particularly useful when the clinical objective is:
- Symptomatic relief of mild pruritus
- Soothing irritated skin
- Providing a superficial protective layer
- Mild drying of weeping/oozing superficial lesions
- Relief of minor irritation
- Symptomatic treatment of prickly heat
- Relief of itching associated with some insect bites
- Symptomatic relief of mild sunburn
Its main advantage is that it is simple, inexpensive and generally well tolerated.
20. Clinical Limitations
Calamine should not be considered a definitive treatment for conditions requiring specific therapy.
It does not eradicate:
- Dermatophytes
- Candida
- Scabies mites
- Bacterial pathogens
- Herpesviruses
It does not replace appropriate treatment for:
- Scabies
- Tinea infections
- Bacterial skin infections
- Moderate/severe eczema
- Significant allergic reactions
- Severe urticaria
- Autoimmune blistering disorders
- Drug eruptions
- Severe burns
- Cellulitis
- Other serious dermatological conditions
In such situations, calamine may sometimes provide symptomatic relief but should not delay diagnosis and definitive treatment.
21. Important Formulation Differences
One of the most important points when discussing calamine is that "calamine lotion" is not necessarily one identical formulation.
Traditional BP-type formulation
Approximately:
- Calamine 15%
- Zinc oxide 5%
with additional excipients.
USP-type formulation
Approximately:
- Calamine 8%
- Zinc oxide 8%
with a different vehicle system.
Modern commercial products
Commercial formulations may contain:
- Glycerin
- Bentonite
- Calcium hydroxide
- Water
- Other excipients
- Occasionally additional active ingredients
Therefore, two bottles labeled "Calamine Lotion" may have different concentrations, excipients, indications, age restrictions and warnings.
22. Frequently Asked Questions (FAQ)
1. Is Calamine 15% Lotion an antibiotic?
No. It is primarily a topical skin protectant, soothing, mildly astringent and antipruritic preparation. It should not be used as a substitute for an antibiotic when a bacterial infection is present.
2. Does calamine treat the cause of itching?
Usually no. It mainly provides symptomatic relief. The underlying cause of the pruritus may still require specific treatment.
3. Can calamine be used for urticaria?
It may provide temporary symptomatic relief of itching, but it does not treat the underlying histamine-mediated process as effectively as appropriate antihistamine therapy.
4. Can it be used for prickly heat?
Yes. Calamine is commonly used as a soothing and drying topical preparation for miliaria/prickly heat, provided the specific product is appropriate for the patient.
5. Can it be used for mild sunburn?
It may provide symptomatic soothing and relief of itching/irritation associated with mild sunburn. It does not replace appropriate sunburn care.
6. Can it be used for insect bites?
Yes, calamine preparations are commonly used for symptomatic relief of itching associated with minor insect bites and stings.
7. Should the bottle be shaken?
Yes. Calamine lotion is a suspension, so the bottle should be shaken well before use to redistribute suspended particles uniformly. This is specifically stated in current product labeling.
8. How often can it be applied?
The historical product information supplied here recommends 3–4 times daily. However, current commercial labels differ, with some recommending application as needed. Therefore, follow the instructions on the actual current package.
9. Can calamine be used on children?
Often yes, but the age restriction depends on the exact formulation. Some current labels advise consulting a physician before use in children younger than 2 years.
10. Can it be used during pregnancy?
Simple calamine/zinc oxide lotion is generally considered low risk when used appropriately because systemic absorption is limited. However, the complete formulation should be checked, particularly if it contains additional active ingredients.
11. Can it be used while breastfeeding?
Simple topical calamine/zinc oxide preparations are generally expected to have minimal systemic absorption. Avoid applying it where the infant could ingest it, particularly the nipple/areola immediately before feeding.
12. Can calamine be applied to open wounds?
The historical product information specifically recommends application to intact skin. It is therefore preferable not to apply the product routinely to deep, extensively eroded, ulcerated or severely damaged skin without professional advice.
13. Can calamine be used together with topical corticosteroids?
They can sometimes be used as part of the same treatment plan, but they have different purposes. Calamine provides symptomatic protection/soothing, whereas corticosteroids treat inflammatory skin disease. The appropriate sequence and frequency depend on the specific corticosteroid and condition.
14. Does calamine cause skin dryness?
It can. Its mild astringent/drying properties may be useful for oozing or moist irritation but may worsen dryness if applied excessively to already dry skin.
15. Why is calamine pink?
The pink color is associated with iron oxide/ferric oxide in calamine preparations.
16. Is Calamine 15% the same as every calamine lotion?
No. Different pharmacopoeias and manufacturers use different compositions. A classic BP-type preparation contains 15% calamine and 5% zinc oxide, whereas USP-type formulations commonly contain 8% calamine and 8% zinc oxide.
17. Is the old information saying "Produced by Pharco" still reliable for this product?
Not necessarily. Current publicly available Egyptian listings identify Philo Pharm Pharmaceuticals as the manufacturer of Calamine 15% Lotion 120 mL. Therefore, the old Pharco attribution should not be automatically carried forward to the current Philo Pharm product.
23. Overall Clinical Assessment
Calamine 15% Lotion 120 mL is a traditional topical preparation with a favorable safety profile when appropriately used on intact skin. Its principal clinical value is symptomatic management of mild pruritus, irritation, redness and superficial oozing, through the combined soothing, protective, mildly astringent and drying properties of calamine and zinc oxide.
The formulation supplied for this product — calamine 15% + zinc oxide 5% — corresponds to the traditional BP-type composition. However, calamine lotions are not universally standardized, and the exact excipients and regulatory labeling must be confirmed from the current manufacturer's package insert.
The most important practical points are:
- For external use only.
- Shake well before use.
- Avoid the eyes and mucous membranes.
- Prefer application to intact skin unless specifically advised otherwise.
- Use cautiously in very young children.
- Do not rely on calamine alone when an underlying infection or significant inflammatory disease requires specific treatment.
- Check the current package insert because formulations and approved uses can differ between manufacturers.
- Do not assume that all products labeled "Calamine Lotion" are compositionally identical.

25. Regulatory and Product-Information Note
The information available publicly for the Egyptian product is less comprehensive than the official labeling available for some international calamine products. Therefore, the current Egyptian package insert and the actual bottle/carton supplied by the manufacturer should be considered the definitive source for the current formulation, excipients, approved indications, age restrictions, storage conditions, manufacturer and regulatory status.
In particular, the older information supplied with this review should not be treated as current simply because it appears in an old leaflet. The current public evidence supports identifying the 120-mL Calamine 15% product with Philo Pharm Pharmaceuticals, while the older Pharco attribution appears to relate to a different or historical calamine-lotion product.
