Summary
Amifampridine is used to treat Lambert-Eaton myasthenic syndrome, which is a rare autoimmune disorder affecting the connection between nerves and muscles. This condition leads to muscle weakness and fatigue, and Amifampridine helps improve muscle strength and reduce symptoms.
Amifampridine works by blocking potassium channels in nerve cells, which increases the release of acetylcholine, a chemical that helps nerves communicate with muscles. This action improves muscle strength and reduces symptoms in people with Lambert-Eaton myasthenic syndrome.
The usual starting dose of Amifampridine for adults is 10 mg, taken three to four times a day. The maximum recommended dose is 80 mg per day. Your doctor may adjust your dose based on your response and any side effects. Always follow your doctor's dosing instructions.
Common side effects of Amifampridine include tingling sensations, nausea, and abdominal pain. These effects vary from person to person. If you notice new symptoms after starting Amifampridine, they might be temporary or unrelated to the medication. Talk with your doctor before stopping any medication.
Amifampridine can cause seizures, especially in people with a history of seizures. It's also contraindicated in people with a known allergy to the medication or its ingredients. Always follow your doctor's instructions and report any unusual symptoms or side effects promptly.
