Calamine + Diphenhydramine HydrochlorideThird Party Manufacturing in India

Calamine + Diphenhydramine Hydrochloride works by combining a soothing skin protectant with a potent antihistamine to relieve localized itching and pain. Calamine, which consists of zinc oxide and a small amount of ferric oxide, acts as a mild astringent and skin protectant. Upon application, it evaporates to produce a cooling sensation that distracts from the itch, while also drying up oozing or weeping skin lesions. Meanwhile, diphenhydramine hydrochloride acts as an antihistamine by competitively blocking the H1 receptors on cells. By preventing histamine from binding to these receptors, it halts the allergic cascade that causes intense itching, redness, and swelling. Unlike oral antihistamines, this topical combination delivers localized relief directly to the affected skin without causing systemic side effects like drowsiness. It is exceptionally well-tolerated by both adults and pediatric patients, making it a reliable solution for minor skin irritations such as insect bites, hives, and poison ivy rashes.

• Insect Bites and Stings: The lotion effectively soothes the skin, decreases the allergic response, and prevents scratching from mosquito, bee, wasp, or ant bites.
• Poison Ivy and Oak Rashes: It helps dry up the oozing and weeping vesicles while easing the intense pruritus associated with plant contact dermatitis.
