Loratadine relieves symptoms of itching, runny nose, watery eyes and sneezing.

How to use it?

Loratadine is taken by mouth usually once per day. It is available as a tablet and syrup (usually for children).


The regular adult dosage is 10 mg once daily. Loratadine can be taken at any time, but some people prefer to use it in the evening if they anticipate being exposed to a potential allergen the next day.
