Both cetirizine and loratadine are antihistamines that are used to treat allergies. They work by blocking the effects of histamine, which is released during an allergic reaction. However, there are some differences between these two medications. Cetirizine is a long-acting antihistamine, whereas loratadine is a short-acting antihistamine. Loratadine starts working within one hour, whereas cetirizine takes several hours to take effect. Cetirizine also remains in the body for longer than loratadine.
What is Cetirizine?
Cetirizine is an antihistamine that is used to relieve the symptoms of allergies. It works by blocking histamine, a substance in the body that causes allergic symptoms.
- Cetirizine is available as a generic drug and as the brand-name drug Zyrtec. Generic drugs usually cost less than brand-name versions. Cetirizine is also available in combination with pseudoephedrine (Sudafed, Zyrtec-D).
- Cetirizine can interact with other medications, so be sure to tell your doctor about all the medications you are taking, even those that do not require a prescription.
