Parkinsons Disease Home > Apokyn Uses

By stimulating a specific brain chemical, Apokyn can be used for relieving certain symptoms of Parkinson's disease. Apokyn uses specifically apply to "off" episodes, which are times of muscle stiffness, slow movements, and trouble initiating movements. This prescription medication works by increasing dopamine, a brain chemical that coordinates muscle movement. Apokyn is not approved for use in children.

Uses of Apokyn: An Overview

Apokyn® (apomorphine hydrochloride) is an injectable Parkinson's disease medication. This prescription medication is approved to treat "off" episodes (periods of muscle stiffness, slow movements, and trouble initiating movements) that occur in people with Parkinson's disease. Often, these off episodes occur despite optimal treatment with other Parkinson's medications. Apokyn is used to treat each episode as needed (up to five times a day); it is not taken on a schedule and is not used to prevent off episodes.
 
Parkinson's disease results from the loss of neurons in a region of the brain that controls movement. This creates a shortage of the neurotransmitter (brain-signaling chemical) known as dopamine, causing movement problems that are characteristic of Parkinson's disease. The exact cause of Parkinson's disease is not currently known.
 
Although early symptoms of Parkinson's disease may be subtle, people will eventually develop a characteristic tremor (trembling or shaking) of a limb, especially when the body is at rest. As the disease progresses, symptoms may worsen and new ones may appear.
 
Depending on the severity of a person's symptoms, Parkinson's disease treatment can include:
 
Because Apokyn almost always causes severe nausea and vomiting, a nausea/vomiting medication called trimethobenzamide (Tigan®) must be taken every day, starting three days before starting Apokyn and continuing for at least two months. Although some people may be able to stop taking trimethobenzamide, many will need to continue this medication as long as they take Apokyn.
