Ketotifen, the active ingredient in Ketotifen Wzf, is an antihistamine (H1 receptor antagonist) and mast cell stabilizer presented as an oral dosage form for oral use. It is employed to treat allergic rhinitis, allergic conjunctivitis, and to provide prophylaxis of asthma in both children and adults.

GNH USA supplies Ketotifen Wzf as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides regulatory‑approved batches to meet global demand with reliable logistics and documentation support.

Ketotifen is used in the allergy and asthma therapeutic area to control histamine‑mediated symptoms.

Allergic rhinitis: reduces nasal congestion, itching, sneezing and rhinorrhea. Allergic conjunctivitis: alleviates eye itching, redness, tearing and swelling. Asthma prophylaxis: helps prevent bronchospasm and airway inflammation by stabilizing mast cells.

Ketotifen may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects: - Drowsiness: feeling of sleepiness or reduced alertness. - Dry mouth: decreased salivation leading to thirst. - Headache: mild to moderate head pain. - Nausea: upset stomach or urge to vomit. - Dizziness: sensation of light‑headedness or unsteadiness. - Weight gain: increase in body weight over time. - Abdominal pain: discomfort in the stomach area.

Serious or Rare Side Effects: - Stevens‑Johnson syndrome: severe skin reaction with blistering. - Anaphylaxis: life‑threatening allergic reaction with airway swelling. - Hepatic dysfunction: abnormal liver enzymes or jaundice. - Agranulocytosis: severe reduction in white blood cells. - Cardiac arrhythmia: irregular heart rhythm.

When prescribing ketotifen, several safety considerations should be observed to minimize risk.

Pregnancy: safety not established; avoid unless benefits outweigh risks. Breastfeeding: unknown excretion; consider risk‑benefit before use. Renal impairment: dose adjustment may be needed; monitor renal function. Elderly patients: increased susceptibility to sedation and anticholinergic effects; start low. Concomitant CNS depressants: may enhance drowsiness; use caution. Store at below 25°C: keep in the original container, protect from moisture.

Ketotifen can interact with other medicines, affecting its efficacy or safety.

Major Interactions (Avoid): - Potent CYP3A4 inhibitors: may increase ketotifen plasma concentrations. - Monoamine oxidase inhibitors (MAOIs): risk of additive central nervous system depression. - Other antihistamines: can cause excessive sedation.

Moderate Interactions (Monitor Closely): - Alcohol: may potentiate drowsiness. - CNS depressants (e.g., benzodiazepines): monitor for enhanced sedation. - Theophylline: ketotifen may reduce its bronchodilator effect.
