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.
