The name of your medicine is Orphenadrine 50mg/5ml Oral Solution (called orphenadrine in this leaflet). It contains orphenadrine hydrochloride. This belongs to a group of medicines called anticholinergics.

Orphenadrine can be used for the symptoms of Parkinsonism (usually slow movement, muscle stiffness and shaking fingers). These symptoms can be caused by Parkinson’s Disease, but there are other causes as well.
