1. What Fenistil is and what it is used for

Fenistil is a topical gel. 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 agent with strong antipruritic effects (except in cholestatic pruritus), reduces swelling, and soothes skin irritation.
It also has local anaesthetic properties. Its cooling effect provides additional relief for irritated skin.

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

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