The medication Claritin is an antihistamine that can treat the symptoms of seasonal or indoor allergies, such as sneezing, eyes that itch or water and a nose that is runny. This antihistamine can also treat skin reactions, including hives, a rash and itchy skin, as stated by Drugs.com. Claritin contains the active ingredient loratadine.
Claritin is an over-the-counter medication used mainly for allergies. The way in which this medication works is by lowering or blocking the effects of the body's histamine reaction when there are different allergens present, according to Healthline. The different types of allergens that can trigger a histamine reaction are pet dander, pollen, dust and mold, as noted by the Claritin website.
Claritin can help with allergic rhinitis or hay fever symptoms. The dosing for adults and children 6 years or older is 10 milligrams a day by mouth. For children aged 2 to 5 years old, the dose is 5 milligrams once per day. For hives or urticaria, the dose for adults is 10 milligrams per day, as stated by the Drugs website.
However, there are other Claritin products, such as Claritin-D, that is used if there is nasal congestion caused by either a cold or allergy. However, all Claritin products should be used according to label instructions in terms of dosing. This can avoid possible adverse side effects.
