Parkinsons Disease Home > Amantadine Hydrochloride (HCL)
The U.S. Food and Drug Administration approved the drug amantadine hydrochloride (HCl), sold under the brand name Symmetrel®, for the following uses:
- Preventing and treating certain types of flu
- Treating Parkinson's disease and other similar conditions
- Treating certain side effects of other medications, known as "extrapyramidal symptoms" (such as movement disorders caused by antipsychotic medications).
This drug comes in the form of a tablet and syrup (the generic version is also available as a capsule). It is usually taken by mouth once or twice a day. If your healthcare provider recommends amantadine hydrochloride, tell him or her if you have glaucoma, heart disease, congestive heart failure, or are pregnant or breastfeeding, as this may have an effect on his or her decision to prescribe it.
