Table of contents:

Ampyra, also known as dalfampridine, is a prescription drug used to help improve walking ability in adults with multiple sclerosis (MS). Dalfampridine is a potassium channel blocker. It works by blocking tiny pores, or potassium channels.

Dalfampridine is a medication specifically for improving walking ability in adults with MS. Its efficacy has been demonstrated in randomized controlled clinical trials and several studies have suggested that its use can lead to improved quality of life for those suffering from MS.

Uses and Dosage

Ampyra comes in tablet form to be taken by mouth with or without food twice a day, as directed by a doctor. Swallow the tablet whole and not crush, chew, or break it as this can cause the drug to be released all at once, increasing the risk of side effects. If you are unable to swallow the tablets whole, talk to your doctor.

The dosage of the medication will depend on your medical condition and response to treatment, and you should not take more medication or take it more frequently than prescribed to reduce the risk of side effects such as seizures. Take no more than 2 doses per day, 12 hours apart.
