Loratadine is an antihistamine available in over-the-counter (OTC) medicines that are used to relieve the symptoms of hay fever and other outdoor and indoor allergies. Loratadine can be the only active ingredient in an allergy medicine, or it can be found in medicines that treat other symptoms such as nasal congestion.
Loratadine is approved by the U.S. Food and Drug Administration (FDA) and is safe and effective when used according to the Drug Facts label. Parents and other caregivers should be aware that loratadine-containing medicines may come in different dosage strengths. Some products have dosing instructions for children between the ages of 2 and 6, while other medicines are only recommended for use in adults and children over the age of 6.
