Ampyra and Multiple Sclerosis


Before You Take Ampyra

Have a conversation with your doctor before taking Ampyra. Discuss the risks and benefits of MS medications and have a clear understanding of your treatment choices.

Do not take Ampyra if you:

  • Are taking compounded 4-aminopyridine (fampridine, 4-AP)
  • Have a history of seizures
  • Have moderate to severe kidney impairment

Tell your doctor if you:

  • Have other medical problems, including urinary tract infections
  • Are pregnant or plan to become pregnant
  • Are breastfeeding or plan to breastfeed

You should also let your doctor know if you are taking any other prescription or over-the-counter (OTC) medications, including vitamins and herbal supplements.

After You Begin Taking Ampyra

It's important that you take only the dose your doctor prescribes. If you miss a dose, don't double up on the next one. Taking a higher dose or taking doses closer than 12 hours apart can increase your risk of a seizure. If you experience a seizure while taking Ampyra, stop taking the drug and call your doctor immediately.

You should also let your doctor know if you:

  • Experience other side effects of Ampyra
  • Begin taking any other medications, including over-the-counter drugs
  • Become pregnant
