Allegra Oral Uses
Fexofenadine is an antihistamine that provides relief of seasonal allergy symptoms such as runny or itchy nose, sneezing, itchy throat, and watery, itchy, or red eyes. It is also used for hives.
How To Use Allegra Oral
Take fexofenadine by mouth usually twice a day or as directed by your doctor. If you are taking the suspension, shake the bottle well before use. Take the regular tablet or suspension form of this medication with or without food. If you are using the rapidly dissolving tablet, take it on an empty stomach. Remove the rapidly dissolving tablet from its foil pack immediately before taking and place the tablet on the tongue. It will dissolve quickly. You may swallow the dissolved medication with or without water.
Taking fexofenadine with apple, grapefruit, or orange juice may decrease the absorption of this drug. Try to avoid taking fexofenadine with these types of fruit juices. If possible, take this drug with water instead.
Antacids containing aluminum and magnesium can decrease the absorption of this drug. Do not take antacids within 2 hours of taking this medication.
Do not increase your dose or take this more often than directed. Dosage is based on your medical condition (e.g., kidney disease) and response to treatment. In children, dosage is also based on age.
Do not take this medication for several days before allergy testing since test results can be affected. Consult your doctor or pharmacist for more information.
Inform your doctor if your condition persists or worsens.
