What is Apokyn?
Apokyn (apomorphine) has some of the same effects as a chemical called dopamine, which occurs naturally in your body. Low levels of dopamine in the brain are associated with Parkinson's disease.
Apokyn is used to treat "wearing-off" episodes (muscle stiffness, loss of muscle control) in people with advanced Parkinson's disease.
Apokyn may also be used for purposes not listed in this medication guide.

You should not use Apokyn if you also taking alosetron (Lotronex), dolasetron (Anzemet), granisetron (Kytril), ondansetron (Zofran), or palonosetron (Aloxi).
Before using Apokyn, tell your doctor if you have an electrolyte imbalance (such as low levels of potassium or magnesium in your blood), a slow heart rate, low blood pressure or dizzy spells, a history of "Long QT syndrome," a history of stroke or heart attack, asthma, sulfite allergy, or liver or kidney disease.

How should I use Apokyn?
Use Apokyn exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose. Never use Apokyn in larger amounts, or use it for longer than recommended. Tell your doctor if the medicine seems to stop working as well.
Apokyn is injected under the skin. You may be shown how to use injections at home. Do not give yourself this medicine if you do not understand how to use the injection and properly dispose of used needles and syringes.
Do not inject Apokyn into a vein.
Your care provider will show you the best places on your body to inject Apokyn. Use a different place each time you give an injection. Do not inject into the same place two times in a row.
Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.
Apokyn can cause severe nausea and vomiting. To prevent these symptoms, you may be given anti-nausea medication to start taking a few days before you start using this medicine. Keep taking the anti-nausea medicine throughout your treatment with Apokyn.
Do not take any anti-nausea medicine without first asking your doctor. Some anti-nausea medicines can increase certain side effects of apomorphine, or can make your Parkinson's symptoms worse.
Measuring your Apokyn dose correctly is extremely important. When you use an injection pen with Apokyn, the medicine is measured in milliliters (mL) marked on the pen. However, your prescribed dose may be in milligrams (mg). One milligram, or 1 mg, of apomorphine is equal to 0.1 mL marked on the injection pen.
Do not use Apokyn if it has changed colors or has particles in it. Call your pharmacist for new medication.
When you dial in your dose on the injection pen, make sure there is enough medicine inside the cartridge to make up the full dose. Ask your pharmacist if you have any questions about how to correctly measure your dose.
Your blood pressure will need to be checked often.
Do not stop using Apokyn suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using this medicine.
If you stop using Apokyn for 7 days or longer, ask your doctor before restarting the medication. You may need to restart with a lower dose.
Use a disposable needle only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
Store Apokyn cartridges at room temperature away from moisture and heat.
