Indications & Clinical Uses

Ketotifen is used to manage allergic conditions by stabilizing mast cells and blocking histamine receptors.

  • Allergic rhinitis: reduces nasal congestion, sneezing and itching.
  • Allergic conjunctivitis: alleviates eye itching, redness and watery discharge.
  • Asthma prophylaxis: helps prevent bronchial hyperreactivity and asthma attacks.

How It Works

  • Ketotifen blocks H1 histamine receptors on target cells, preventing histamine‑mediated allergic responses, and stabilizes mast cells, inhibiting the release of inflammatory mediators such as leukotrienes and prostaglandins. This dual action reduces both early‑phase and late‑phase allergic reactions.

Side Effects

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

Common Side Effects

  • Drowsiness or sedation.
  • Dry mouth.
  • Headache.
  • Nausea or gastrointestinal discomfort.
  • Increased appetite or weight gain.

Serious or Rare Side Effects

  • Severe skin reactions such as Stevens‑Johnson syndrome.
  • Anaphylactic reactions.
  • Hepatotoxicity indicated by elevated liver enzymes.
  • Blood dyscrasias including neutropenia or agranulocytosis.

Precautions & Warnings

When using Ketotifen, certain precautions should be observed to ensure safety.

  • Pregnancy: use only if clearly needed; consult a healthcare professional.
  • Breastfeeding: assess risk versus benefit before use.
  • Driving or operating machinery: avoid if experiencing drowsiness.
  • Hepatic impairment: monitor liver function regularly.
  • Concomitant CNS depressants: use with caution as sedation may increase.
  • Store below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Avoid Interactions

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

Major Interactions (Avoid)

  • Other antihistamines or sedating drugs: may intensify drowsiness.
  • Monoamine oxidase inhibitors (MAOIs): risk of additive antihistaminic effects.

Moderate Interactions (Monitor Closely)

  • CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): may increase ketotifen plasma levels.
  • CYP3A4 inducers (e.g., rifampicin, carbamazepine): may reduce ketotifen effectiveness.
  • Theophylline: monitor for potential additive bronchodilator effects.

Frequently Asked Questions

Ketotifen Hasco is used to relieve symptoms of allergic rhinitis, allergic conjunctivitis and to help prevent asthma attacks. It works by blocking histamine receptors and stabilising mast cells, which reduces the release of inflammatory substances that cause allergy symptoms.

Ketotifen blocks H1 histamine receptors, preventing histamine from triggering allergic responses. At the same time it stabilises mast cells, limiting the release of mediators such as leukotrienes and prostaglandins. This dual mechanism reduces both immediate and delayed allergic reactions.

The appropriate dose of ketotifen is determined by a qualified prescriber based on the patient’s age, condition and response. Dosage instructions are provided on the prescription label and should be followed exactly as directed by the healthcare professional.

Safety data for ketotifen in pregnancy and lactation are limited. Use only if the potential benefit justifies any possible risk to the fetus or infant, and always discuss with a healthcare provider before starting treatment while pregnant or nursing.

To order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any required import documentation.

Ketotifen combines H1‑receptor antagonism with mast‑cell stabilisation, offering both symptom relief and a preventive effect on allergic inflammation. Many other antihistamines act only on H1 receptors, so ketotifen may provide added benefit for patients needing both immediate relief and longer‑term control.

Ketotifen Hasco should be stored below 25 °C in its original packaging, protected from moisture and direct sunlight. Keeping the product in a dry, cool place helps maintain its stability and potency throughout its shelf life.

Ketotifen Hasco is taken orally, usually as a tablet, with or without food as directed by the prescriber. Swallow the tablet whole with a glass of water and follow the dosing schedule provided on the prescription label.

Serious risks, though rare, include severe skin reactions such as Stevens‑Johnson syndrome, anaphylaxis, liver enzyme elevations indicating possible hepatotoxicity, and blood disorders like neutropenia. Patients should seek immediate medical attention if they notice any
