1. What is Fenistil and what is it used for

Fenistil contains dimetindene maleate, which belongs to a group of antihistamine medicines. It inhibits the action of histamine - a substance responsible for allergic reactions. It relieves itching and irritation caused by skin rash, reduces swelling, and also relieves symptoms of allergic rhinitis, such as runny nose (cold), sneezing, nasal itching, and eye itching and tearing. After oral administration, the effect of the medicine starts after 30-60 minutes and lasts for 8 to 12 hours. Fenistil is used to treat symptoms of allergic diseases:

• skin: urticaria, itching in atopic dermatitis, allergic contact dermatitis, endogenous eczema,
• respiratory system: seasonal allergic rhinitis (hay fever) and chronic allergic rhinitis (e.g., house dust allergy, pet hair, feathers).

The medicine is used to treat symptomatic food and drug allergies, as well as to relieve itching associated with infectious diseases (e.g., chickenpox). It can be used to relieve symptoms that occur after insect bites and to prevent allergic reactions that occur during desensitization treatment. If after 7 days there is no improvement or you feel worse, you should contact your doctor.

2. Important information before using Fenistil
