What is apomorphine used for?
Apomorphine is used to treat “wearing-off” episodes (muscle stiffness, loss of muscle control) in people with advanced Parkinson’s disease.
Apomorphine may also be used for purposes not listed in this medication guide.
How should I take apomorphine?
Follow all directions on your prescription label. Your doctor may occasionally change your dose. Never use apomorphine in larger amounts, or use it for longer than recommended. Tell your doctor if the medicine seems to stop working as well.
Apomorphine 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 apomorphine into a vein.
Your care provider will show you the best places on your body to inject apomorphine. 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.
Apomorphine 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 apomorphine. Keep taking the anti-nausea medicine throughout your treatment with apomorphine.
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 apomorphine dose correctly is extremely important. When you use an injection pen with apomorphine, 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 apomorphine 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 apomorphine 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 apomorphine suddenly, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using apomorphine.
If you stop using apomorphine 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.
How do I store apomorphine?
Apomorphine is best stored at room temperature away from direct light and moisture. To prevent drug damage, you should not store apomorphine in the bathroom or the freezer. There may be different brands of apomorphine that may have different storage needs. It is important to always check the product package for instructions on storage, or ask your pharmacist. For safety, you should keep all medicines away from children and pets.
You should not flush apomorphine down the toilet or pour them into a drain unless instructed to do so. It is important to properly discard this product when it is expired or no longer needed. Consult your pharmacist for more details about how to safely discard your product.
