What is the difference between cetirizine and levocetirizine?
Can you tell me what the difference is between cetirizine and levocetirizine?
Certainly! Both cetirizine and levocetirizine are antihistamines used to treat allergies. However, they differ in their chemical structure and how they work in the body. Levocetirizine is a purified form of cetirizine, and is actually the active enantiomer (or stereo-isomer) of cetirizine.
