About three-fourths of people with MS have trouble walking. It can be one of the most challenging parts of the condition.
Dalfampridine (Ampyra) is a medication that helps you get around more easily. Unlike other MS treatments, it won’t keep symptoms from getting worse or change the course of the disease -- it’s just intended to improve how you walk.
Ampyra helps electrical signals move better along the nerves in your brain and spinal cord. When you have MS, your nerves lose the protective coating, called myelin, that helps messages zip up and down your body. That means your muscles don’t get clear signals that tell them when and how to move.
Ampyra restores the flow of those signals and helps your nerves send their messages more effectively.
How Do You Take It?
You’ll need a prescription from your doctor. You take one 10-milligram tablet twice a day, 12 hours apart. You should never take more than one pill at once or more than two in 24 hours.
You can take Ampyra with or without food. Swallow the tablets whole. Don’t break, crush, chew, or dissolve them before you take them. That could release the medication too fast in your body, possibly causing a seizure.
Take only the dose your doctor prescribes. If you miss a dose, don't double up on the next one. If you take a higher dose or take them less than 12 hours apart, you can increase your risk of a seizure. If that happens, stop taking the drug and call your doctor right away.
