General Information on Fexofenadine Dosage
Fexofenadine comes in tablets, orally disintegrating tablets (ODTs), and oral suspension (liquid). It is taken by mouth, usually once or twice daily.
Fexofenadine orally disintegrating tablets rapidly dissolve on the tongue. Be sure to swallow (either with or without water) after the tablet has dissolved.
Be sure to shake fexofenadine oral suspension well just before each dose.
For fexofenadine tablets and oral suspension, it does not matter if you take it with or without food. However, fexofenadine orally disintegrating tablets should be taken on an empty stomach.
Fexofenadine should not be taken with fruit juices, as juice may affect the way your body handles the medication.
For fexofenadine to work properly, you have to take it as prescribed. Allergy symptoms will most likely return if you stop taking it.
If you forget to take a dose of fexofenadine, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your normal dosing schedule. Never double your dose of fexofenadine to make up for a missed dose.
If you are unsure about anything related to fexofenadine or your fexofenadine dosage, please talk to your doctor, nurse, or pharmacist. Do not stop taking fexofenadine without first discussing it with your healthcare provider.
