FEXOFENADINE (AllegraŽ) is an antihistamine. It reduces allergy symptoms of hay fever (seasonal allergic rhinitis), and may reduce itching of the skin in those people with chronic itchy skin rashes.
They need to know if you have any of these conditions:
Take fexofenadine tablets by mouth, with a sip of water. Do not take this medicine with grapefruit, orange, or apple juice because they may change how well the medicine works. Follow the directions on the prescription label. Take your doses at regular intervals. Do not take fexofenadine more often than directed. You may need to take it for several days as prescribed before your symptoms improve.
Contact your pediatrician or health care professional regarding the use of this medicine in children. Special care may be needed. Fexofenadine is usually prescribed for children 6 years of age and older.
If you miss a dose, take it as soon as you can. If it is almost time for your next dose, take only that dose. Do not take double or extra doses.
