Clarinex, also known by its generic name desloratadine, is an antihistamine drug used to relieve the symptoms of allergies, such as sneezing, runny nose, itching, and watery eyes. It belongs to a class of medications called H1-antihistamines and works by blocking the action of histamine, a substance in the body that causes allergic symptoms. Clarinex is available in various forms, including tablets, oral solution, and orally disintegrating tablets.

Safety Measures

Clarinex should not be used by individuals who are hypersensitive to desloratadine or any of the inactive ingredients present in the formulation. It is also contraindicated for patients with severe liver impairment.

Adverse Reactions

Common side effects of Clarinex include headache, dry mouth, fatigue, nausea, and drowsiness. Less commonly, individuals may experience allergic reactions, such as rash, itching, swelling, and difficulty breathing. If any severe or persistent side effects occur, it is important to seek medical attention immediately.

Proper Use

Clarinex should be taken exactly as prescribed by a healthcare professional. The recommended dose for adults and children 12 years and older is 5 mg once daily. For children 6 to 11 years old, the recommended dose is 2.5 mg once daily. The oral solution should be measured with a dose-measuring device to ensure accurate dosing.

If a dose of Clarinex is missed, it should be taken as soon as remembered unless it is close to the time for the next scheduled dose. In such cases, the missed dose should be skipped and the regular dosing schedule should be followed. Taking a double dose to make up for a missed dose is not recommended.

In case of an overdose, individuals should seek immediate medical attention or contact a poison control center. Symptoms of overdose may include drowsiness, rapid heartbeat, dry mouth, and dilated pupils.

How Other Drugs Affect Clarinex

Clarinex may interact with other medications, so it is important to inform the healthcare provider about all the drugs being taken. The concomitant use of Clarinex with drugs that inhibit certain liver enzymes, such as ketoconazole or erythromycin, may increase the levels of Clarinex in the blood. This can potentially lead to an increased risk of side effects. On the other hand, the concomitant use of drugs that induce liver enzymes, such as rifampin or phenytoin, may decrease the levels of Clarinex.

In addition, caution should be exercised when combining Clarinex with other central nervous system depressants, such as alcohol or sedatives, as it may enhance the sedative effects of these drugs.
