Numark Calamine Lotion BP Calamine and Zinc Oxide

What Is Calamine Lotion and How Does It Soothe Skin?

If you have ever dealt with the relentless itch of chickenpox, insect bites, or a patch of irritated skin, you will know how much relief a simple, trusted remedy can bring. Calamine lotion has been used in the UK for generations precisely because it works — gently, safely, and without fuss. Numark Calamine Lotion BP contains two active ingredients, calamine 15% w/v and zinc oxide 5% w/v, formulated to the British Pharmacopoeia standard. At just £2.99, it is one of the most affordable and accessible skin-soothing options available over the counter. You can browse the full range of skin care products at Cured Pharmacy if you are looking for something more targeted alongside this lotion.

This lotion is classified as a General Sale List (GSL) medicine in the UK, meaning you do not need a prescription to buy it. It is suitable for adults, children, and the elderly, though you should always check with a pharmacist if you are unsure whether it is right for a particular person or condition.

How Does Numark Calamine Lotion BP Work on Irritated Skin?

The mechanism behind calamine lotion is straightforward but effective. When you apply it to the skin, the water in the lotion evaporates and produces a gentle cooling sensation — this is what immediately takes the edge off that maddening itch. The two active ingredients each play a distinct role:

• Calamine — a mixture of zinc carbonate and ferric oxide — acts as a mild antipruritic (anti-itch) agent and gives the lotion its characteristic pink colour.
• Zinc oxide acts as a mild astringent, helping to reduce inflammation, protect the skin barrier, and dry out any weeping or oozing areas.
• Together, they create a thin, protective film on the skin surface that reduces irritation and helps prevent scratching-related damage.
• The lotion base also contains glycerol, which provides a degree of skin moisturisation as it dries.

It does not contain steroids or antihistamines, so it is unlikely to cause the systemic effects associated with those medicines. That makes it a reassuring first-line option for many common skin complaints.

Who Is Numark Calamine Lotion BP Suitable For?

This lotion is designed for anyone experiencing mild to moderate skin irritation where itching is the primary symptom. It is particularly well suited to:

• Children and adults with chickenpox (varicella) — to relieve itching and discourage scratching
• People with insect bites or stings causing localised itching and redness
• Those with mild sunburn where the skin feels hot and irritated
• Anyone with a mild allergic skin reaction causing itching without broken skin

It is not suitable for use on broken, infected, or severely inflamed skin without medical advice. If you are pregnant or breastfeeding, speak to your pharmacist before use, though topical calamine is generally considered low risk. For bite-related reactions that also involve sneezing or watery eyes, you might also want to explore allergy and hay fever treatments alongside this lotion.

Is Calamine Lotion Safe to Store at Home and Use Long Term?

Numark Calamine Lotion BP should be stored below 25°C, away from direct sunlight, and kept out of the reach and sight of children. The bottle should be shaken well before each use, as the ingredients can settle. Once opened, check the expiry date on the packaging and do not use beyond it. Calamine lotion is intended for short-term, symptomatic relief — it is not a treatment for the underlying cause of a skin condition. If your symptoms persist for more than seven days or worsen, you should seek advice from your GP or pharmacist. For broader skin health support, the creams and ointments collection at Cured Pharmacy includes a range of options for different skin concerns.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

What Are the Possible Side Effects of Numark Calamine Lotion BP?

Like all medicines, this product can cause side effects, although not everyone will experience them. Calamine lotion is generally very well tolerated when used as directed.

Common side effects:

• Mild skin dryness at the application site — this is due to the astringent effect of zinc oxide
• A temporary white or pink residue on the skin as the lotion dries

Less common side effects:

• Mild skin irritation or a burning sensation at the application site
• Contact dermatitis (allergic skin reaction) — rare, but possible if you are sensitive to any ingredient
• Redness or worsening of the treated area

If you experience any signs of a serious allergic reaction — such as swelling of the face, lips, or throat, difficulty breathing, or a widespread rash — stop using the lotion immediately and seek urgent medical attention. For children with chickenpox, the NHS advises keeping nails short and using mittens at night to prevent scratching, alongside the use of calamine lotion for itch relief.
