What is claritin?

Claritin is the brand name for loratadine, an over-the-counter antihistamine used to treat allergy symptoms and hives.

Key points:
- What it does: Blocks H1 histamine receptors to reduce sneezing, runny nose, itchy or watery eyes, and itching of the nose or throat.
- How it acts: It’s a second-generation antihistamine, so it’s designed to cause less drowsiness than older antihistamines.
- Common uses: Seasonal allergies (hay fever), allergic rhinitis, and chronic hives (urticaria).
- How long it lasts: Typically taken once daily, with effects within 1–3 hours and symptom relief lasting about 24 hours.
- Forms and dosing: Available as 10 mg tablets (adult and many teens), as well as chewables and syrup for children; always follow the product label or a clinician’s instructions.
- Side effects: Most people don’t get drowsy, but possible effects include headache, dry mouth, or fatigue. Serious side effects are uncommon.
- Important notes: Claritin-D and other Claritin formulations with decongestants (like pseudoephedrine) can raise blood pressure or cause jitteriness; avoid in certain medical conditions unless advised by a clinician.
- If you’re pregnant, breastfeeding, have liver or kidney disease, or take other medicines, check with a healthcare professional before using.
