1. What is ZABAK and what is it used for

ZABAK is an eye drop solution, preservative-free, containing ketotifen, which is an antiallergic agent.
ZABAK is used for the treatment of symptoms of seasonal allergic conjunctivitis.
The most common symptoms of seasonal allergic conjunctivitis are intense itching of both eyes, accompanied by redness, swelling, excessive tearing, conjunctival edema, and sensitivity to light. These symptoms are recurring and start with the beginning of the pollen season. Seasonal allergic conjunctivitis may also be associated with other symptoms of hay fever, such as rhinitis.
If after 7 days there is no improvement or you feel worse, you should contact your doctor (see section 2).

2. Important information before using ZABAK

  • visual disturbances,
  • morning eyelid sticking, difficulty opening the eyes in the morning,
  • swelling of lymph nodes in the ear area,
  • persistent symptoms (persistence of symptoms),
  • unilateral symptoms. If any of the above symptoms occur, the patient may have another eye condition than seasonal allergic conjunctivitis. You should consult a doctor.

You should tell your doctor or pharmacist about all medicines you are taking or have recently taken, as well as any medicines you plan to take.
