Popular FAQ

Does loratadine raise blood pressure?

Loratadine (brand example: Claritin), an over-the-counter (OTC) non-sedating antihistamine, does not usually increase blood pressure when used alone as a single ingredient. Some OTC combination products do contain loratadine plus the decongestant pseudoephedrine (brand example: Claritin-D), which can raise your blood pressure. In the US, Claritin-D and the generic are normally kept behind the pharmacy counter. If you have high blood pressure, are being treated for high blood pressure, or have concerns about your blood pressure, ask your doctor before you use pseudoephedrine in any form.

Does loratadine make you sleepy?

Loratadine does not usually cause drowsiness and is considered a non-sedating antihistamine. However, some people may get sleepy so use caution before driving, operating machinery or performing other hazardous tasks until you know how loratadine affects you.
