1. What Fenistil is and what it is used for

Fenistil is a topical gel for skin application. Fenistil contains the active substance dimetindene maleate, which inhibits the action of histamine – a substance responsible for allergic reactions.
When applied to the skin, Fenistil acts locally as an antiallergic and strongly antipruritic agent (except in cholestatic pruritus), reduces swelling, and soothes skin irritation.
It also has local anaesthetic properties. Its cooling effect further helps to relieve irritated skin.

Indications:
Itching associated with skin disorders, urticaria, insect bites, sunburn, and superficial skin burns (first-degree burns).

If there is no improvement after 2 days of treatment in children or 7 days in adults, or if your condition worsens, consult a doctor.
