Allegra

Allegra is one of the more popular antihistamine drugs on the market. Allegra is most commonly used as a drug to treat hay fever and allergies. One of the other names by which Allegra is sometimes marketed is Telfast, and the chemical name for Allegra is Fexofenadine hydrochloride. The Allegra pill does not cause as much drowsiness as some of the earlier generation antihistamines, as it does not cross the blood to brain barrier as easily. Allegra was originally created as a replacement for the drug terfenadine (which was marketed under the name Triludan), as terfenadrine had some contraindicating factors that were potentially fatal, making it a somewhat risky choice for an allergy medication. There has been no evidence so far that a fatality could result from an overdose of Allegra.

Some of the various Allegra side effects are nausea, vomiting, weakness, and drowsiness or sleepiness. Allegra 24 can be taken with or without food. These is a possibility, although it has not been clearly established, of Allegra weight gain. Allegra, Zyrtec and other similar prescription drugs that are used for fighting the effects of allergies and hay fever should be purchased over the counter; Allegra is a prescription only medication in the United States and is classified an Over The Counter drug in Canada and Australia. You can purchase Allegra in Canada and Australia without a prescription, but in America it is illegal to buy Allegra online or to by Allegra D online without a prescription.
