It is important to remember that doctors prescribe amantadine hydrochloride because its therapeutic benefits outweigh its potential side effects. Common side effects may include lightheadedness, drowsiness, dry mouth, and lowered blood pressure.

Serious side effects are very rare but may include psychosis, renal impairment, and constipation. If you are experiencing any of these side effects, call your doctor right away.

Before starting treatment with amantadine, talk to your doctor about your health history and any medication you may be taking. Amantadine may not be prescribed for women who are breastfeeding, as it may be released into breast milk. Similarly, if you are taking another anticholinergic (anti-spasm) or neuroleptic (anti-psychosis) medication, your doctor may choose not to prescribe amantadine, as formulations of these drugs can cause toxicity in the blood.

This is not a complete list of side effects associated with amantadine. For more information on adverse effects you may experience while taking amantadine, please visit the National Institutes of Health’s DailyMed webpage.

The standard dosage of amantadine as a treatment for Parkinson's starts at a 100-137 milligram pill taken orally twice a day. It is not meant to be taken with food, so it is recommended that the pill is taken right away in the morning and right before bed.

In patients age 65 or older, it is generally recommended that the dosage is lowered to 100 mg/ day.

In all cases, you must follow your doctor's orders about daily dosage. After assessing your symptoms and your health conditions, your doctor will create a prescription plan that is safe and effective. An overdose of amantadine can lead to renal impairment and symptoms of psychosis. Follow the instructions on the medication bottle, and talk to your doctor about any concerns you may have.
