Desloratadine is indicated for the treatment of hay fever and allergic symptoms in both adults and children. These symptoms may include sneezing, a runny nose, and ocular manifestations such as redness, itching, and tearing of the eyes. Desloratadine is additionally employed for alleviating symptoms associated with urticaria, characterized by raised, itchy areas on the skin, including itching and rash.
Functioning as an antihistamine, desloratadine inhibits the activity of histamine, a physiological substance responsible for eliciting allergic responses within the body.
Uses and Dosage
Desloratadine is available in tablet form, oral solution, and orally disintegrating tablet, all intended for oral administration. It is typically taken once a day, with or without food. Follow the prescribed dosage precisely, refraining from taking more or less of the medication or altering the frequency of administration beyond the doctor’s instructions.
The dosage is based on your age, medical condition, and response to treatment. Do not increase your dose or take this medication more often than directed.
When using the oral solution, employ a measuring device, such as a dropper or an oral syringe, to ensure accurate measurement of each dose. Avoid using a household spoon for this purpose.
To take the orally disintegrating tablet, ensure your hands are dry, and carefully peel back the foil packaging. Place the tablet directly on your tongue, where it will rapidly dissolve and can be swallowed with saliva. Orally disintegrating tablets may be consumed with or without water.
