Claritin-D

Claritin-D is an over the counter medication used to relieve symptoms of seasonal allergies, and nasal congestion. It is a single product containing 2 medications: loratadine and pseudoephedrine. Claritin-D belongs to a group of drugs called Histamine H1 Antagonists (antihistamine), and nasal decongestants. Antihistamines work by blocking the action of histamine, which is known to trigger allergy symptoms. Nasal decongestants work by narrowing the blood vessels and reducing the swelling inside your nasal passage, which allow you to breathe easier. 

This medication comes in an extended release tablet, and is usually taken once daily with or without food. Do not chew, divide, or break Claritin-D. Swallow tablets whole. 

Common side effects of Claritin-D include headaches, shakiness/trembling, and fast heartbeat. Claritin-D can also cause drowsiness. Do not drive or operate heavy machinery until you know how Claritin-D affects you.
