This medication comes in many forms which are taken according to age group, severity of symptoms, and other factors. The regular Clarinex tablets relieve symptoms for up to 24 hours and are safe for ages 12 and up. Clarinex 24-hour combines the power of antihistamine and decongestant for people with seasonal rhinitis and congestion. Children as young as 6 months of age can receive relief from indoor allergies, while children 2 and over can experience relief from outdoor ones, with the bubblegum flavored Clarinex syrup.
DRUG CLASS AND MECHANISM: Desloratadine is an oral, long-acting antihistamine that is similar chemically to loratadine (Claritin). It is used to treat the symptoms caused by histamine. Histamine is a chemical that is responsible for many of the signs and symptoms of allergic reactions, for example, swelling of the lining of the nose, sneezing, and itchy eyes. Histamine is released from histamine-storing cells (mast cells) and then attaches to other cells that have receptors for histamine. The attachment of the histamine to the receptors causes the cell to be "activated," releasing other chemicals which produce the effects that we associate with allergy.
Do not use any other over-the-counter cold, allergy, or sleep medication without first asking your doctor or pharmacist. If you take certain products together you may accidentally take too much of a certain drug. Read the label of any other medicine you are using to see if it contains an antihistamine or decongestant.
