Claritin (loratadine) is an antihistamine that reduces the effect of the natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.
Take Claritin exactly as directed on the label, or as your doctor has prescribed. Do not use in larger or smaller amounts or for longer than recommended.
Claritin is usually taken once per day. Follow your doctor's instructions.
Do not crush, chew, or break the regular Claritin tablet. Swallow the pill whole.
Measure liquid form of Claritin with a special dose-measuring spoon or cup, not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.
