Sudafed Dosage

General Information on Dosing With Sudafed

Considerations for people taking Sudafed include the following:
 
  • This medication comes in immediate-release tablets (Sudafed), extended-release tablets (Sudafed 12 Hour or 24 Hour), and a liquid (Children's Sudafed Liquid). The instructions for use vary with each different product.
     
  • Do not break, chew, cut, or crush the extended-release tablets, as this will cause the medication to be released too quickly.
     
  • You can take Sudafed with food or on an empty stomach. If the medication seems to bother your stomach, try taking it with a little food.
     
  • Because there are a few different Sudafed products available, be sure to follow the instructions for your particular product.
     
  • Some people find that Sudafed interferes with their ability to fall asleep. If you experience this problem, try taking your last dose earlier in the day.
     
  • For the medication to work properly, it must be taken as directed.
     
  • If you are unsure about anything related to your dosage, please talk with your doctor, nurse, or pharmacist.
