Clarinex antihistamine?

Clarinex is the brand name for desloratadine, a second‑generation antihistamine. It’s used to relieve allergy symptoms (seasonal or perennial allergic rhinitis: runny nose, sneezing, itchy eyes/nose) and to treat hives (urticaria). It’s designed to be non-sedating for most people.

Key points:
- Typical adult dose: 5 mg once daily.
- Dosing for children depends on age and product formulation (there are syrups and chewables). Always follow the product label or your clinician’s instructions.
- Common side effects: headache, fatigue, dry mouth. Serious side effects are rare.
- Drowsiness is less likely than with first‑generation antihistamines, but alcohol can increase any sedative effect.
- Interactions: certain medicines (for example, some antifungals or antibiotics that strongly inhibit CYP enzymes) can raise desloratadine levels. Tell your healthcare provider about all medicines you take.
- Pregnancy/breastfeeding: consult a clinician before use.
