1. What Fenistil is and what it is used for

Fenistil contains dimetindene maleate, which belongs to a group of medicines called antihistamines.
It blocks the action 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 eye itching and watering.
After oral administration, the effect of the medicine begins within 30–60 minutes and lasts for 8 to 12 hours.
Fenistil is used to treat symptoms of allergic conditions:

• of the skin: urticaria, itching associated with 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 fur, 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 during desensitization therapy. If there is no improvement after 7 days, or if you feel worse, consult your doctor.

2. Important information before using Fenistil

When not to use Fenistil oral drops:

• if the patient is allergic to dimetindene maleate or any of the other ingredients of this medicine (listed in section 6),
• in newborns during the first month of life, especially in premature infants.

Consult a doctor before using this medicine in patients:

• with glaucoma,
• with urinary retention, e.g. due to enlarged prostate,
• with epilepsy,
• in elderly patients.

Elderly patients should contact a doctor before using this medicine, as they are more susceptible to adverse effects of this medicine, such as excitation and fatigue.
This medicine should not be used in elderly patients with disorientation.

Antihistamine medicines may cause excitation in young children.
The use of Fenistil in infants aged 1 month to 1 year and in children under 6 years of age should be under medical advice.
Do not exceed the recommended dose.
Keep the medicine out of sight and reach of children.
Fenistil and other medicines
Tell your doctor about all medicines the patient is currently taking or has recently taken, including those obtained without a prescription.
Do not use Fenistil without medical advice if taking any of the following medicines:

Use of Fenistil with alcohol
Like other antihistamines, Fenistil may enhance the effects of alcohol.
Pregnancy, breastfeeding, and fertility
If the patient is pregnant or breastfeeding, suspects she may be pregnant, or is planning to have a child, she should consult a doctor or pharmacist before using this medicine.
Fenistil should not be used during pregnancy unless the benefits to the mother outweigh the potential risks to the fetus. The medicine may be used only under medical supervision.

Fenistil contains benzoic acid, propylene glycol, and sodium.

Before administering the medicine to a child under 4 weeks of age, consult a doctor or pharmacist, especially if the child is taking other medicines containing propylene glycol or alcohol.
The medicine contains less than 1 mmol (23 mg) of sodium per dose (40 drops), meaning the medicine is considered "sodium-free".
