What Are the Benefits of Ampyra for Multiple Sclerosis?

About three-fourths of people with MS have difficulty walking and many find walking problems to be among the most debilitating effects of the disease. In clinical trials, patients treated with Ampyra were able to walk faster than those receiving an inactive pill, or placebo.

Ampyra is the first drug approved to improve walking in MS patients. Other treatments for MS are designed to slow disease progression and prevent relapses by suppressing the immune system, which is believed to be involved in the myelin damage.

What Are the Potential Side Effects of Ampyra?

In clinical trials of Ampyra, the most common side effects included:

Some patients also experienced a relapse of their MS.

  • Have a history of seizures
  • Have moderate to severe kidney impairment

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
