All About Amantadine: What It Does and How To Use It Safely

Amantadine is a medication that you might encounter if you're dealing with certain viral infections or Parkinson's disease. Originally developed as an antiviral, amantadine also helps ease symptoms in Parkinson's by improving muscle control and movement. If you've been prescribed this drug or are curious, it’s good to understand how it works, what to expect, and how to use it safely.

What Is Amantadine Used For?

Primarily, amantadine fights off influenza A virus infections. It’s not as common for flu nowadays, but in some cases, doctors still recommend it. More commonly, you’ll find amantadine used to treat Parkinson’s disease. It helps reduce shakiness, stiffness, and difficulty moving. Sometimes, it’s combined with other Parkinson’s medications to get better control over symptoms.

People also use amantadine to help with drug-induced Parkinsonism—a condition caused by certain medications that affect movement. If you’ve noticed side effects like tremors from other drugs, amantadine might be suggested to bring your symptoms down.

Side Effects and What to Watch For

Like any drug, amantadine comes with possible side effects. Common ones include dizziness, lightheadedness, dry mouth, or trouble sleeping. You might feel a bit restless or notice mild swelling in your legs. If you feel confused, have hallucinations, or unusual mood swings, it’s important to tell your doctor right away.

Watch the dose carefully; taking too much amantadine can lead to serious problems like difficulty breathing or severe agitation. It's also wise to avoid alcohol or be cautious with other medicines that make you sleepy while on amantadine. This drug can interact with several medications, so your healthcare provider should know everything you're taking to avoid issues.

Lastly, don’t stop amantadine suddenly without checking with your doctor, especially if used for Parkinson’s, as this can worsen symptoms.

Getting familiar with amantadine helps you feel in control and work with your doctor to get the best results. If you notice anything concerning, don't wait—reach out to your healthcare provider to keep your treatment safe and effective.
