Allegra is one of the new type of antihistamines that causes no or less drowsiness. Allegra works by blocking the release of histamine from the cell at the histamine receptor site and relieving the symptoms of seasonal allergies and hay fever like the itchy, runny nose, sneezing, and watery eyes. Allegra's effect begins in an hour and lasts up to twelve hours.
Avoid Allegra if you are allergic or sensitive to it.
Those who have kidney disease should be given smaller doses.
Common side effects of Allegra may include drowsiness, headache, fatigue, indigestion, and dry mouth.
Rare side effects of Allegra may include nausea, nervousness, cough, stuffy nose, and throat irritation.
Check with your doctor before combining Allegra with erythromycin or ketoconazole.
Otherwise, Allegra is less likely than other antihistamine to interact with drugs.
Though generally considered safe, do not take Allegra without the advice of your physician if you are or planning to become pregnant.
Nursing mothers should switch to bottle-feed while taking Allegra as it does pass into breast milk.
CHILDREN (6-11 years)

ADULTS (12and older)

People with kidney disease should take smaller doses (60mg/day).
Symptoms of Allegra overdose may include drowsiness, dizziness, nausea, nervousness, and dry mouth.
In case of Allegra overdose, seek medical help right away.
