hydrochloride) is a prescription medication used to treat Parkinson's disease
. Specifically, it is used "as needed" to help reverse the symptoms of "off" episodes (periods of muscle stiffness, slow movements, and trouble initiating movements). It is given as an injection just under the skin. Because the medication usually causes very severe nausea and vomiting, it is almost always given along with Tigan®
(trimethobenzamide), a medication that helps to reduce these side effects.

How Does It Work?
Apokyn is classified as a dopamine agonist. This means that it works much like dopamine, a naturally occurring brain chemical. Apokyn binds to dopamine receptors and stimulates them, much like natural dopamine. A dopamine deficiency (caused by a loss of dopamine-producing cells) in certain parts of the brain may be responsible for many of the symptoms of Parkinson's disease. Because Apokyn acts much like natural dopamine, it can help relieve Parkinson's symptoms.
Despite the name of its active ingredient (apomorphine), Apokyn does not bind to morphine
receptors and does not act like morphine.
