Symmetrel

Uses
Symmetrel (Amantadine Hydrochloride) is a medicine that is widely used to treat symptoms of Parkinson's disease, and to prevent or treat influenza A. In addition to this, some patients have used it for shingles. When use for Parkinson's, the patient may be instructed to take it alongside other medicines. It works by causing an increased amount of dopamine to be released in the brain, which may help to provide relief from tremors and stiffness, while also improving the patient's movement.

This medicine can also work as an antiviral, and has been used to treat patients with influenza A, so as to prevent health complications, or to prevent infection in people considered to be at risk. Other possible uses for this drug have been researched, such as treating chronic fatigue in patients with multiple sclerosis, treating ADHD and depression.

Dosage and Administration
Symmetrel (Amantadine Hydrochloride) capsules must be taken exactly as directed by your doctor. Adults who are being treated for Parkinson's disease are usually instructed by their doctor to take 100mg twice per day. However, if required, the doctor may decide to adjust the dosage. Some older adults may only require a dosage of 100mg per day. The dosage for influenza (either treatment or prevention) and any other conditions may be different, and in all cases, the doctor will decide the right amount to take.
