Why is this medication prescribed?

Dalfampridine, marketed under the brand name Ampyra, is primarily prescribed to improve walking in adults with multiple sclerosis (MS). Multiple sclerosis is a chronic illness affecting the central nervous system, leading to symptoms such as muscle weakness, difficulty with coordination and balance, and problems with walking. Dalfampridine works by blocking potassium channels on nerve cells, which can enhance signal conduction and improve walking ability in some MS patients.

How should this medicine be used?

Dalfampridine, marketed under the brand name Ampyra, is a medication used to improve walking in patients with multiple sclerosis (MS). Here are the key guidelines for its use:

  • Dosage: The typical dosage of Dalfampridine is 10 mg taken orally twice a day, approximately 12 hours apart. Do not take more than 20 mg in a 24-hour period.
  • Administration: Swallow the tablets whole. Do not crush, chew, or break them. Take the medication with or without food. If you miss a dose, do not take an extra dose to make up for it. Wait until the next scheduled dose.
  • Timing: Consistency in timing is important. Take the medication at the same times each day to maintain an even level in your bloodstream.
  • Monitoring: Regularly follow up with your healthcare provider to monitor your progress and any side effects. Your kidney function may need to be tested before and during treatment, as Dalfampridine is excreted through the kidneys.
  • Side Effects: Common side effects include urinary tract infections, insomnia, dizziness, headache, nausea, and weakness. Serious side effects can include seizures. If you experience a seizure, stop taking the medication and seek medical attention immediately.
  • Precautions: Dalfampridine should not be used if you have a history of seizures or moderate to severe kidney impairment. Inform your healthcare provider of all medications you are taking, as Dalfampridine can interact with other drugs.
  • Storage: Store the medication at room temperature, away from moisture and heat. Keep it out of reach of children.

Always use Dalfampridine under the supervision of a healthcare provider, and follow their specific instructions based on your individual health condition.
