1. What Fenistil is and what it is used for

Fenistil contains dimetinden maleate, which belongs to a group of medicines called antihistamines.
It blocks the effects of histamine, a substance in the body responsible for allergic reactions. It relieves itching and irritation caused by skin rashes, reduces swelling, and also alleviates symptoms of allergic rhinitis such as watery nasal discharge (runny nose), sneezing, nasal itching, and itchy, watery eyes.
After oral administration, the effect of the medicine begins within 30–60 minutes and lasts for 8 to 12 hours.
Fenistil is indicated for the treatment of symptoms of allergic conditions:

• of the skin: urticaria, itching in atopic dermatitis, allergic contact dermatitis, endogenous eczema;
• of the respiratory system: seasonal allergic rhinitis (hay fever) and perennial allergic rhinitis (e.g. allergy to house dust, animal hair, feathers). Fenistil is used for symptomatic treatment of food and drug allergies, and also relieves itching associated with infectious diseases (e.g. chickenpox). It may be used to relieve symptoms following insect bites and to prevent allergic reactions occurring during desensitization therapy. If there is no improvement after 7 days, or if you feel worse, consult your doctor.

2. Information before using Fenistil

When not to use Fenistil oral drops:

• if the patient is allergic to dimethindene maleate or any of the other ingredients of this medicine (listed in section 6),
