This medication is an antihistamine that treats symptoms such as itching, runny nose, watery eyes, and sneezing from "hay fever" and other allergies. It is also used to relieve itching from hives. Loratadine does not prevent hives or prevent/treat a serious allergic reaction (anaphylaxis).

What happens when you take Claritin?

Claritin blocks the action of histamine, a substance in the body that initiates allergic symptoms like itching, sneezing, runny nose, and allergic skin rashes.

How does Claritin make you feel?

Claritin (loratadine) typically causes less drowsiness compared to other antihistamines, but some people may feel a little sleepy while taking this medication. If you aren't getting enough allergy relief from taking Claritin (loratadine), there may be other options that might work better for you.
