Loratadine: MedlinePlus Drug Information

Loratadine comes as a syrup (liquid), a tablet, and a rapidly disintegrating (dissolving) tablet to take by mouth. It is usually taken once a day with or without food. Follow the directions on the package label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take loratadine exactly as directed. Do not take more or less of it or take it more often than directed on the package label or recommended by your doctor. If you take more loratadine than directed, you may experience drowsiness.

If you are taking the rapidly disintegrating tablet, follow the package directions to remove the tablet from the blister package without breaking the tablet. Do not try to push the tablet through the foil. After you remove the tablet from the blister package, immediately place it on your tongue and close your mouth. The tablet will quickly dissolve and can be swallowed with or without water.

Do not use loratadine to treat hives that are bruised or blistered, that are an unusual color, or that do not itch. Call your doctor if you have this type of hives.

Stop taking loratadine and call your doctor if your hives do not improve during the first 3 days of your treatment or if your hives last longer than 6 weeks. If you do not know the cause of your hives, call your doctor.

If you are taking loratadine to treat hives, and you develop any of the following symptoms, get emergency medical help right away: difficulty swallowing, speaking, or breathing; swelling in and around the mouth or swelling of the tongue; wheezing; drooling; dizziness; or loss of consciousness. These may be symptoms of a life-threatening allergic reaction called anaphylaxis. If your doctor suspects that you may experience anaphylaxis with your hives, he may prescribe an epinephrine injector (EpiPen). Do not use loratadine in place of the epinephrine injector.

Do not use this medication if the safety seal is open or torn.
