Amantadine Dosage for Parkinson’s Disease

Amantadine typically starts at a low dose of 100 mg once or twice daily. Your doctor will carefully monitor your response and may gradually increase your dosage, but usually not exceeding 400mg per day. This increase happens in increments, often by 100mg every few days, depending on your tolerance and the improvement in your symptoms.

Adjustments Based on Response

Dose adjustments depend entirely on individual needs and response. Some patients may experience sufficient relief at a lower dose, while others might need the maximum recommended daily dose. Significant side effects might necessitate dose reduction or discontinuation. Regular check-ups with your neurologist are critical to optimize your treatment plan.

Common Dosage Regimens & Side Effects

While there’s no one-size-fits-all approach, here’s a simplified table illustrating common dosage regimens and potential side effects:

Daily Dosage (mg) Typical Administration Possible Side Effects
100 Once daily Dizziness, nausea, insomnia
200 Twice daily (100mg twice) Increased dizziness, anxiety, livedo reticularis
300 Three times daily (100mg three times) Severe ankle edema, hallucinations, confusion
400 Twice daily (200mg twice) Increased risk of serious side effects; careful monitoring required.

Important Considerations

Always follow your doctor’s instructions precisely. Never adjust your dosage without consulting your physician. Report any new or worsening symptoms immediately. Amantadine interacts with certain medications, so inform your doctor of all medications you are taking, including over-the-counter drugs and supplements.
