Tell your prescriber or health care professional about all other medicines you are taking, including non-prescription medicines, nutritional supplements, or herbal products. Also tell your prescriber or health care professional if you are a frequent user of drinks with caffeine or alcohol, if you smoke, or if you use illegal drugs. These may affect the way your medicine works. Check with your health care professional before stopping or starting any of your medicines.
What should I watch for while taking amantadine?
Let your prescriber or health care professional know if your symptoms do not improve in a few days.
You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how amantadine affects you. To reduce the risk of dizzy or fainting spells, do not sit or stand up quickly, especially if you are an older patient. Alcohol can make you more drowsy and dizzy, increase confusion and lightheadedness. Avoid alcoholic drinks.
If you are taking amantadine for a movement disorder, do not suddenly stop taking it. You may get muscle stiffness, paralysis, confusion, or find it difficult to pass urine.
If you are taking amantadine for Parkinson's disease, be careful not to overdo physical activity as your condition improves. Gradually increase activity so that your body has time to adjust.
Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water will help. Brush and floss teeth regularly and carefully to avoid problems with the mouth and gums.
What side effects may I notice from taking amantadine?
Side effects that you should report to your prescriber or health care professional as soon as possible:
• blurred vision, or any change in vision
• difficulty passing urine
• fainting
• hallucinations (seeing things that are not really there)
• seizures (convulsions)
• swelling of the feet or legs
Side effects that usually do not require medical attention (report to your prescriber or health care professional if they continue or are bothersome):
• anxiety, irritability, nervousness
• difficulty sleeping, or nightmares
• dizziness
• dry mouth
• purplish spots or network on the skin
