Asfen (Ketotifen) is a potent antihistamine which exhibits strong H1-receptor blocking activity. In addition it has been shown to possess anti anaphylactic properties and is effective in preventing asthmatic attack.


Each 5 ml syrup contains Ketotifen Fumarate BP 1.38 mg equivalent to 1.00 mg Ketotifen.


– Prophylactic treatment of bronchial asthma.
– Allergic rhinitis.
– Allergic conditions such as hay fever, itchy rash or reactions to insect bites.

Dosage and administration

6 months to 3 years: 0.25 ml / kg body weight, twice daily (Once in the morning & once in the evening).


Hypersensitivity to  Ketotifen  or  any  other  components  of the formulation. Patient sensitive to Benzoate compounds should not take Ketotifen.

Side Effect

Drowsiness and in isolated cases dry mouth and slight dizziness may occur at the beginning of treatment but usually disappear spontaneously after a few days.

Pregnancy: Its safety in human pregnancy has not been established. Ketotifen should therefore be given to pregnant women only in compelling circumstances.

Lactation: Ketotifen is excreted in breast milk. Therefore mothers receiving Ketotifen should not breast-feed.
