What is Claritin?

Claritin is an antihistamine that reduces the effects of natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.

Claritin is used to treat sneezing, runny nose, watery eyes, hives, skin rash, hay fever, itching, and other cold or allergy symptoms.

Claritin is also used to treat skin hives and itching in people with chronic skin reactions

How should I take Claritin

Use Claritin exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Cold or allergy medicine is usually taken only for a short time until your symptoms clear up.

Do not give Claritin to a child younger than 2 years old. Always ask a doctor before giving a cough or cold medicine to a child. Death can occur from the misuse of cough and cold medicines in very young children.

Claritin is usually taken once per day. Follow your doctor's instructions.

Do not crush, chew, or break the regular tablet. Swallow the tablet whole.

A child's dose is based on age and some forms of loratadine are not for use in children younger than 6 years old. Carefully follow the dosing instructions provided with this medicine.

Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.

The Claritin chewable tablet must be chewed before you swallow it.

To take the orally disintegrating tablet (Claritin RediTab):

  • Keep the tablet in its blister pack until you are ready to take it. Open the package and peel back the foil. Do not push a tablet through the foil or you may damage the tablet.

  • Use dry hands to remove the tablet and place it in your mouth.

  • Do not swallow the tablet whole. Allow it to dissolve in your mouth without chewing. If desired, you may drink liquid to help swallow the dissolved tablet.

Call your doctor if your symptoms do not improve, or if they get worse.
