Is Zyrtec vegan?

Updated: May 11, 2023

Allergies can be a real nuisance, causing symptoms like sneezing, itching, runny nose, and watery eyes that can affect your daily activities and quality of life. For many, Zyrtec has become a go-to medication for managing these uncomfortable symptoms, but determining which Zyrtec product is animal-free can be difficult.

What is in Zyrtec (cetirizine)?

Zyrtec is the brand name for cetirizine. Cetirizine is an antihistamine medication used to treat allergy symptoms. It works by blocking the effects of histamine, a substance produced by the body in response to an allergen.

Zyrtec is available over-the-counter in various forms, including tablets, capsules, and liquid. It is generally considered safe and effective for most people when taken as directed, but it’s always best to consult with your doctor or pharmacist before taking any new medication.
