1. What is Fenistil and what is it used for
Fenistil contains dimetindene maleate, which belongs to a group of antihistamine medicines. It counteracts 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 action 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 itching accompanying infectious diseases (e.g., chickenpox). It can be used to relieve symptoms after insect bites and to prevent allergic reactions during desensitization treatment. If there is no improvement after 7 days or the patient feels worse, they should contact their doctor.
