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 other 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.
Apokyn may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert. Some people using this medicine have fallen asleep during normal daytime activities such as talking, eating, or driving. You may fall asleep suddenly, even after feeling alert. If this happens to you, stop taking Apokyn and talk with your doctor.
You may have increased sexual urges, unusual urges to gamble, or other intense urges while taking this medication. Talk with your doctor if you believe you have any intense or unusual urges while taking Apokyn.

How should I use Apokyn?
Never use Apokyn in larger amounts, or use it for longer than recommended by your doctor. Follow the directions on your prescription label. 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 self-inject this medicine if you or your caregivers do not fully understand how to give the injection and properly dispose of used needles and syringes.
Do not inject Apokyn into a vein. Measuring your Apokyn dose correctly is extremely important. If you use an injector pen with your apomorphine, the medication 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 dosing pen. Do not use the medicine if it has changed colors, looks green or cloudy, or has particles in it. Call your doctor for a new prescription.
Use a different place on your stomach, arm, or thigh each time you give the injection. Your care provider will show you the best places on your body to inject Apokyn. Do not inject into the same place two times in a row.
Use a disposable needle only once. Throw away used needles in a puncture-proof container (ask your pharmacist where you can get one and how to dispose of it). Keep this container out of the reach of children and pets.
Apokyn can cause severe nausea and vomiting. For this reason, your doctor may prescribe an anti-nausea medication for you to start taking a few days before you begin using Apokyn. You may also need to keep using the anti-nausea medicine throughout your treatment with Apokyn.
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.
Do not stop using Apokyn suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to avoid withdrawal symptoms when you stop using Apokyn.
Store Apokyn at room temperature, away from heat, moisture, and light.
What happens if I miss a dose?
Use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. Overdose symptoms may include nausea, extreme drowsiness, or fainting.
What should I avoid?
Apokyn may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert. Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall. Do not drink alcohol. It can further lower your blood pressure and may increase certain side effects of Apokyn.
