General Allegra-D Dosage Information

Some considerations for people taking Allegra-D include:
 
  • Allegra-D comes in a tablet form. It is recommended that you take your Allegra dose with a glass of water, without food.
     
  • Do not break, chew, or crush the Allegra-D tablets.
     
  • Allegra-D should be taken at the same time each day to help maintain an even level of medicine in the blood. Do not take it more often than directed.
     
  • For Allegra-D to work properly, you have to take it as prescribed. Allegra-D will not work if you stop taking it.
     
  • If you forget to take a dose of Allegra-D, 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 Allegra-D at one time.
     
  • Occasionally, the inactive components of Allegra-D may be eliminated in the feces looking very similar to the tablet.
     
  • If you are unsure about anything related to Allegra-D or your Allegra-D dosage, please talk to your doctor, nurse, or pharmacist. Do not stop taking Allegra-D without first discussing it with your healthcare provider.
