General Relpax Dosage Information

Some considerations for people taking Relpax include the following:

  • Take Relpax as soon as possible once a migraine starts.
  • Swallow Relpax tablets whole with a drink of water or other fluid.
  • If instructed to do so by your healthcare provider, you may take a second dose of Relpax if your migraine does not go away after the first dose. However, you must wait at least two hours after the first dose before taking a second dose of Relpax. Do not take more than 80 mg of Relpax in a 24-hour period.
  • You may take your Relpax dosage with or without food.
  • For Relpax to work properly, you have to take it as prescribed. Relpax will not work if you take it differently than how your healthcare provider prescribed it.
  • If you are unsure about anything related to Relpax or your Relpax dosage, please talk to your doctor, nurse, or pharmacist.
