Clarinex is a medication which can be taken year-round by those who suffer from allergies. It is also effective at treating those who suffer from hives or rashes. The active ingredient in this medication is desloratadine, which is an antihistamine. This blocks the immune system's production of the natural chemical histamine, which is produced when the body becomes sensitive to something.

Clarinex is effective at treating allergy symptoms produced from contact to both indoor allergens and outdoor ones. Anything from dust mites, pet dander, and mold spores, to pollen, grass or weeds can cause allergies.

Clarinex is widely used and popular because of its non-drowsy characteristic. Many antihistamines tell users to avoid machinery or driving while taking it, but Clarinex does not. This drug was also the first to boast that grapefruit juice did not affect its absorption.

It is also safe for most people who suffer form asthma to use this medication, although it is recommended that one contacts their doctor before mixing medications of any kind. Reported side effects include dry mouth, fatigue and a sore throat.

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.

The syrup formula can also reduce the appearance of hives in children. Because many people are unable to easily take pills or tablets, Clarinex has provided a solution. For those who need another method, Clarinex Redi-tabs melt easily in the mouth. These also provide 24-hour relief and come in a fruit flavor.

The makers of Clarinex, Shering-Plough, claim that taking this medication in the morning will relieve symptoms all the way into the next morning when one awakes. This is a benefit, since many 24-hour solutions seem to wear off while one is sleeping.
Clarinex-D is a stronger formula which does require a prescription.

This also claims to have 24-hour relief all the way through to the next day. This member of the Clarinex family is for moderate to severe allergy sufferers.
