A healthcare provider may prescribe Clarinex® (desloratadine) tablets, RediTabs®, or syrup to treat hives and allergies in adults and children. This prescription medication is part of a class of drugs called antihistamines. As the name implies, the drug blocks the effects of histamine. This can help with relief of allergy symptoms. However, because histamine is not involved with nasal congestion, Clarinex will not help open the nasal passages.
Although most people tolerate this medication well, side effects are possible. Some of the common side effects include fatigue, nausea, and a sore throat.
The medication comes in several forms and is typically taken once a day by mouth (orally). Clarinex dosage amounts will vary, depending on several factors, such as your age, other medications you are currently taking, other medical conditions you may have, and the condition being treated. Clarinex is available in the following forms and strengths:
- Clarinex oral tablets: 5 mg
- Clarinex RediTabs (orally disintegrating tablets): 2.5 mg and 5 mg
- Clarinex syrup: 2.5 mg/5 mL, each teaspoon (5 mL) contains 2.5 mg.
