1. What is Ketotifen WZF and what is it used for
Ketotifen WZF is an antiallergic medicine containing ketotifen, used in adults and children over 3 years old:
- to prevent asthma attacks in patients with bronchial asthma;
- to treat nasal and eye symptoms associated with allergic rhinitis and allergic conjunctivitis (such as a stuffy nose, excessive watery discharge from the nose, itching of the nose, frequent sneezing, redness of the eyes, tearing, itching of the eyes).
2. Important information before taking Ketotifen WZF
When not to take Ketotifen WZF:
- If you are allergic to ketotifen or any of the other ingredients of this medicine (listed in section 6).
- If you have epilepsy.
- If you are taking oral antidiabetic medicines.
- If you are breastfeeding.
Warnings and precautions
Before starting treatment with Ketotifen WZF, discuss it with your doctor or pharmacist.
Note: Ketotifen WZF is not effective in treating acute allergic reactions and in interrupting asthma attacks.
- If you have epilepsy or have had seizures, you should consult your doctor before taking the medicine.
- If allergy tests are planned, you should stop taking the medicine 10-14 days before they are performed.
- In the initial period of treatment with ketotifen, you should not suddenly stop taking previously used anti-asthmatic medicines, especially corticosteroids, as adrenal insufficiency may occur. Therefore, it is recommended to gradually discontinue corticosteroids over a longer period while taking ketotifen.
- If you are taking antidiabetic medicines, you should inform your doctor. In patients taking Ketotifen WZF together with oral antidiabetic medicines, transient decreases in platelet count have been observed in rare cases, so you should not take antidiabetic medicines and Ketotifen WZF at the same time (see section "When not to take Ketotifen WZF").
Ketotifen WZF may enhance the effect of alcohol. Therefore, you should not drink alcohol while taking Ketotifen WZF.
In case of slowed reaction in the patient, probably due to the sedative effect of the medicine, you should consult your doctor, who will reduce the dose.
