How does Allegra work?
In simple terms, the allergic reaction that is hay fever is an effect of histamine imbalance in the body. It causes symptoms such as sneezing, coughing, itching, runny nose and watery eyes. Allegra brings down the levels of this naturally produced histamine to give relief from the allergic reaction.
Side Effects of Allegra
Being a medication for allergic effects, there are very few Allegra side effects experienced from this drug. Even these are generally mild and include an upset stomach, menstrual pain, cough, fever, earache and dizziness. If however, these become worrisome, you should seek alternatives from your doctor. When taken at the right dose, the chances of any sort of Allegra side effects are minimal. However, an overdose might result in dry mouth, drowsiness and other symptoms that may or may not be dangerous.
One major precaution to be taken during treatment with Allegra is to avoid alcohol as it can increase the level of histamine in the body and make this medicine ineffective.
