Indications & Clinical Uses

  • Ketotifen is an antihistamine that acts on allergic and asthmatic pathways, providing symptom relief and prophylaxis.
  • Allergic rhinitis: reduces nasal congestion, itching and sneezing associated with seasonal or perennial allergies.
  • Allergic conjunctivitis: alleviates eye itching, redness and tearing caused by allergen exposure.
  • Asthma prophylaxis: helps prevent bronchial hyper‑responsiveness and asthma attacks when used as part of a long‑term management plan.

How It Works

  • Ketotifen works by blocking H1 histamine receptors, which prevents histamine‑mediated allergic responses such as vasodilation, increased vascular permeability, and sensory nerve activation. In addition, it stabilises mast cells, inhibiting the release of inflammatory mediators like leukotrienes and prostaglandins, thereby reducing both early and late phase allergic reactions.

Side Effects

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

Common Side Effects

  • Drowsiness or fatigue
  • Dry mouth or throat
  • Headache
  • Nausea or abdominal discomfort
  • Weight gain
  • Blurred vision or eye irritation

Serious or Rare Side Effects

  • Stevens‑Johnson syndrome or toxic epidermal necrolysis
  • Severe skin rash or hypersensitivity reactions
  • Hepatic dysfunction or elevated liver enzymes
  • Anaphylaxis or severe allergic response
  • Blood dyscrasias such as agranulocytosis
  • Severe neutropenia or thrombocytopenia

Precautions & Warnings

  • When using Ketotifen, certain precautions should be observed to ensure safety and effectiveness.
  • Assess hepatic function: evaluate liver status before initiating therapy.
  • Monitor for sedation: advise patients not to operate machinery if drowsy.
  • Avoid driving or hazardous tasks: especially during dose titration.
  • Use caution in glaucoma: may increase intra‑ocular pressure.
  • Avoid in known hypersensitivity: discontinue if allergic reaction occurs.
  • Store at ambient temperature: keep in original packaging, protect from moisture and excessive heat.

Avoid Interactions

Ketotifen can interact with several medicines, requiring attention to avoid reduced efficacy or increased toxicity.

Major Interactions (Avoid)

  • MAO inhibitors: risk of hypertensive crisis.
  • Other sedating antihistamines: additive CNS depression.
  • Central nervous system depressants (e.g., benzodiazepines, opioids): enhanced drowsiness.
  • Alcohol: may intensify sedation and impair coordination.

Moderate Interactions (Monitor Closely)

  • CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): may increase ketotifen plasma levels.
  • Anticholinergic agents: could exacerbate dry mouth.
  • Beta‑blockers: may blunt bronchodilator response in asthmatic patients.

Frequently Asked Questions

Ketotifen Teva is used to treat allergic rhinitis, allergic conjunctivitis, and to help prevent asthma attacks. It works by reducing the body’s histamine response and stabilising mast cells, which together lessen allergy symptoms and improve breathing in susceptible individuals.

Ketotifen blocks H1 histamine receptors, preventing histamine from causing typical allergy symptoms such as itching, swelling, and redness. It also stabilises mast cells, reducing the release of inflammatory mediators like leukotrienes and prostaglandins, which helps control both early and late allergic reactions.

The appropriate dose of Ketotifen Teva is determined by the prescribing healthcare professional based on the patient’s age, condition severity, and response to therapy. Patients should follow the prescriber’s instructions and not adjust the dose without medical guidance.

Safety data for ketotifen in pregnancy and lactation are limited. It should only be used if the potential benefit justifies any possible risk to the fetus or infant. Women who are pregnant, planning to become pregnant, or breastfeeding should discuss use with their healthcare provider.

To order Ketotifen Teva, 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 necessary import documentation.

Ketotifen combines H1‑receptor antagonism with mast‑cell stabilisation, offering both immediate allergy relief and longer‑term prophylaxis. Unlike many first‑generation antihistamines that only block histamine, ketotifen’s dual action can be advantageous for patients needing both symptom control and asthma prevention.

Ketotifen Teva should be stored at ambient temperature, below 25 °C. Keep the product in its original packaging, protect it from moisture and direct sunlight, and ensure the container is tightly closed to maintain stability.

Ketotifen Teva is taken orally, usually as a tablet. It should be swallowed with a full glass of water, and can be taken with or without food as directed by the prescriber. Consistency in timing helps maintain steady blood levels.

Serious risks include rare but severe skin reactions such as Stevens‑Johnson syndrome, hepatic dysfunction, and blood disorders like agranulocytosis. Patients should seek immediate medical attention if they notice unexplained rash, jaundice, fever, or signs of infection.

Ketotifen Teva should not be used by individuals with known hypersensitivity to ketotifen or any of its excipients. Caution is also advised for patients with severe liver impairment, glaucoma, or those taking interacting medications listed under major or moderate interactions.
