General Dosage Information

Some considerations for people taking Allegra include the following:
 
  • Allegra comes in the form of tablets, orally disintegrating tablets (ODTs), and oral suspension (liquid). It is taken by mouth, usually once or twice daily.
     
  • Allegra 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 Allegra oral suspension well just before each dose.
     
  • For Allegra tablets and oral suspension, it does not matter if you take it with or without food. However, Allegra orally disintegrating tablets should be taken on an empty stomach.
     
  • Allegra should not be taken with fruit juices, as juice may affect the way your body handles Allegra.
      
  • For Allegra 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, 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 Allegra dose at one time.
     
  • If you are unsure about anything related to Allegra or your Allegra dosage, please talk to your doctor, nurse, or pharmacist. Do not stop taking Allegra without first discussing it with your healthcare provider.
