Ebastine is used to manage allergic conditions mediated by histamine release.

Allergic rhinitis: alleviates nasal congestion, sneezing, itching and rhinorrhea. Chronic idiopathic urticaria: reduces frequency and severity of wheals and itching. Seasonal allergic conjunctivitis: diminishes eye redness, tearing and itching associated with pollen exposure.

Like all antihistamines, ebastine may cause adverse reactions ranging from mild to serious.

Common Side Effects: - Headache: mild to moderate intensity. - Dry mouth: transient sensation of oral dryness. - Drowsiness: occasional mild sedation, less frequent than first‑generation agents. - Fatigue: feeling of reduced energy. - Nausea: mild gastrointestinal upset.

Serious or Rare Side Effects: - Cardiac arrhythmia: irregular heart rhythm reported rarely. - Severe skin reactions: such as Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Anaphylaxis: acute allergic response requiring emergency care. - Hepatotoxicity: elevated liver enzymes or liver injury in rare cases.

Before initiating ebastine therapy, consider the following precautions. - Pregnancy: safety not established; use only if benefit outweighs risk. - Breastfeeding: caution advised; monitor infant for possible effects. - Elderly patients: may be more susceptible to sedation; start at lower dose if needed. - Renal or hepatic impairment: dose adjustment may be required; monitor function. - Concomitant medications: review for potential interactions, especially CYP3A4 inhibitors. - Store at ambient temperature below 25°C: keep in the original pack, protect from moisture.

Ebastine can interact with other medicines; awareness of major and moderate interactions helps ensure safe use.

Major Interactions (Avoid): - Ketoconazole: strong CYP3A4 inhibitor may increase ebastine plasma levels. - Erythromycin: macrolide antibiotic can raise ebastine concentrations. - Ritonavir: potent CYP3A4 inhibitor may lead to heightened exposure.

Moderate Interactions (Monitor Closely): - Theophylline: may increase risk of central nervous system side effects. - CNS depressants (e.g., benzodiazepines): additive sedation possible. - Antifungal agents (e.g., itraconazole): may modestly elevate ebastine levels.
