aged over 3 years:
- for the prevention of asthma attacks in patients suffering from bronchial asthma;
- for the treatment of nasal and ocular symptoms associated with allergic rhinitis and allergic conjunctivitis (such as nasal congestion, profuse watery nasal discharge, nasal itching, frequent sneezing, redness of the eyes, tearing, eye itching).

Warnings and precautions
Before starting treatment with Ketotifen WZF, discuss it with a doctor or pharmacist.
Warning: Ketotifen WZF is not effective in treating acute allergic reactions or in stopping asthma attacks.
- If the patient suffers from epilepsy or has had seizures, they should consult a doctor before using this medicine.
- If allergy testing is planned, the medicine should be discontinued 10–14 days before the tests.
- During the initial phase of treatment with ketotifen, previously used anti-asthmatic medicines, especially corticosteroids, should not be abruptly discontinued, as adrenal insufficiency may occur. Therefore, corticosteroids should be gradually withdrawn over a prolonged period while using ketotifen.
- If the patient is taking antidiabetic medicines, this should be reported to the doctor. In rare cases, transient reduction in platelet count has been observed in patients taking Ketotifen WZF together with oral antidiabetic medicines. Therefore, concomitant use of antidiabetic medicines and Ketotifen WZF is not recommended (see section "When not to use Ketotifen WZF").
Ketotifen WZF may enhance the effects of alcohol. Therefore, alcohol should not be consumed during treatment with Ketotifen WZF.
If the patient experiences slowed reactions, possibly due to the sedative effect of the medicine, they should consult a doctor, who may reduce the dose.
