Fenkarol tablets contain the active ingredient ketotifen, which is an antihistamine medication. It works by blocking the release of histamine, a substance that is produced by the body during an allergic reaction, and thus helps to relieve allergy symptoms such as sneezing, itching, runny nose, and watery eyes.

Fenkarol tablets are typically used to treat allergic rhinitis, which is a condition that causes inflammation in the nasal passages and is often triggered by allergens such as pollen, dust, and animal dander. They can also be used to treat other allergic conditions such as conjunctivitis (pink eye) and hives.

The tablets are usually taken orally with or without food, as directed by a healthcare professional. The dosage and duration of treatment will depend on the individual's age, medical history, and the severity of their symptoms.

Fenkarol tablets are generally well-tolerated, but like any medication, they may cause side effects. Common side effects include drowsiness, dizziness, dry mouth, and stomach upset. These side effects are usually mild and go away on their own, but if they persist or become severe, it is important to consult a healthcare professional.

Overall, Fenkarol tablets are an effective treatment option for allergy symptoms and can help improve quality of life for those suffering from allergic conditions. However, it is important to follow the instructions of a healthcare professional when taking the medication and to seek medical attention if any concerns arise.
