General Information on Your Dose of Allegra-D

Some considerations to keep in mind when taking Allegra-D include the following:
 
 
  • This medication comes in tablet form. It is recommended that you take your Allegra-D dose with a glass of water, without food.
     
  • Do not break, chew, or crush the tablets.
     
  • Allegra-D should be taken at the same time each day to help maintain an even level in the blood. Do not take it more often than directed.
     
  • For Allegra-D to work properly, you have to take it as prescribed. The medicine will not work if you stop taking it.
     
  • If you forget to take a dosage of Allegra-D, take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and continue with your normal schedule. Do not take a double dose.
     
  • Occasionally, the inactive components of Allegra-D may be eliminated in the feces, looking 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 the drug without first discussing it with your healthcare provider.
