What are the differences between Claritin and phenylephrine?
Claritin and phenylephrine are two common over-the-counter (OTC) medications used to relieve allergy symptoms. However, they work in different ways and target different symptoms.
[1] Claritin, also known as loratadine, is an antihistamine that blocks the action of histamine, a natural chemical released by the body during an allergic reaction. It's specifically designed to target nasal congestion, sneezing, runny nose, itchy eyes, and hives.
On the other hand, phenylephrine is a decongestant that works by constricting blood vessels in the nasal passages. This reduces swelling and congestion, providing quick relief from nasal stuffiness.
How long does it take for Claritin and phenylephrine to start working?
Claritin typically starts working within 1-2 hours after taking a dose, while phenylephrine's effects can be noticeable within 30 minutes to 1 hour.

What are the common side effects of Claritin and phenylephrine?
