Fenistil Gel is an antihistamine gel designed for the quick relief of itching and irritation associated with allergic reactions, insect bites, and mild sunburn. The active ingredient, dimetindene maleate, works by blocking histamine, a compound that causes allergic symptoms in the body. This gel is fast-absorbing and provides localized relief from itching, redness, and discomfort. Suitable for both adults and children over 1 month old, it is ideal for use on minor skin irritations.
