Uses
This medication is used to treat the symptoms of Parkinson's disease. It can improve your ability to move during frequent "off" periods. It can decrease shakiness (tremor), stiffness, slowed movement, and unsteadiness. This medication is thought to work by helping to restore the balance of a certain natural substance (dopamine) in the brain.
Apomorphine is used to treat "off" episodes when they occur. It is not used to prevent "off" episodes. This drug should not be used instead of your usual medications for Parkinson's disease. Continue taking all your medications as directed by your doctor.
How To Use
Read the Patient Information Leaflet and Instructions for Use if available from your pharmacist before you start using apomorphine and each time you get a refill. If you have any questions, consult your doctor or pharmacist.
Learn all preparation and usage instructions in the product package. If any of the information is unclear, consult your doctor or pharmacist.
Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Check the dose carefully before injecting. Apomorphine is given by the milliliter, not by the milligram. There are 10 milligrams of drug in each milliliter of this liquid, so if the wrong measuring unit is used, you may accidentally inject 10 times the amount of drug you need. Be sure you have the correct dose to prevent accidental overdose. If you are not sure how to measure your dose correctly, consult your pharmacist before injecting.
If you are using the prefilled cartridge/pen, keep track of the doses used to make sure there is enough medication left in the device to give you a full dose.
Clean the injection site before injecting. Inject this medication under the skin as needed to treat decreased/frozen muscle movement ("off" episode) as directed by your doctor. You may need to use this medication several times a day. Do not use a second injection for the same "off" episode. Wait at least 2 hours between injections.
Do not inject this medication into a vein. It is important to change the location of the injection site with each dose to avoid problem areas under the skin. Choose a different injection site with each dose. The abdomen, thighs, and upper arms are recommended sites for the injection. Do not inject into skin that is irritated, sore, or infected. Learn how to store and discard needles and medical supplies safely. Never reuse syringes or needles. Consult your pharmacist for details.
Dosage is based on your medical condition and response to treatment. To decrease the risk of side effects (such as nausea, drowsiness, low blood pressure) when you first start using apomorphine, your doctor will slowly increase your dosage until the best dose for you is reached. Your doctor will usually have you use the first dose in the office where your blood pressure can be checked and you can be watched for side effects. A health care professional will also teach you to inject this medication correctly. Nausea is very common with this medication. To decrease the risk of nausea, your doctor may direct you to start taking another medication (such as trimethobenzamide) 3 days before your first dose of apomorphine and to continue taking as directed for up to 2 months.
Use this medication as prescribed. If you stop using this medication for longer than 1 week, you may need to increase your dose slowly back to your previous dosage. Talk with your doctor about how to restart the medication. Do not stop using this medication without your doctor's approval.
If you are using this medication often and suddenly stop using it, you may have withdrawal symptoms (such as anxiety, depression, confusion, fever, muscle stiffness). To help prevent withdrawal, your doctor may lower your dose slowly. Withdrawal is more likely if you have used apomorphine for a long time or in high doses. Tell your doctor or pharmacist right away if you have withdrawal.
Rarely, abnormal drug-seeking behavior (drug abuse) is possible with this medication. Do not increase your dose or use it more often than prescribed. Properly stop the medication when so directed.
Tell your doctor if your condition lasts or gets worse.
Side Effects
Redness/swelling/pain/itching at the injection site, nausea, vomiting, headache, sweating, dizziness, drowsiness, yawning, or runny nose may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor right away if you have any serious side effects, including:
- uncontrolled movements
- mental/mood changes (such as confusion, agitation, hallucinations)
- muscle cramps/spasm
- swelling of the hands/legs/ankles/feet
- unusual strong urges (such as increased gambling, increased sexual urges)
- unusual tiredness
- pale skin
Get medical help right away if you have any very serious side effects, including:
- chest pain
- shortness of breath
- unusually fast/pounding/irregular heartbeat
- severe dizziness
- fainting
- trouble speaking
- vision changes
- weakness on one side of the body
Some people using apomorphine have fallen asleep suddenly during their usual daily activities (such as talking on the phone, driving). In some cases, sleep occurred without any feelings of drowsiness beforehand. This sleep effect may occur anytime during treatment with apomorphine even if you have used this medication for a long time. If you experience increased sleepiness or fall asleep during the day, do not drive or take part in other possibly dangerous activities until you have discussed this effect with your doctor. Your risk of this sleep effect is increased by using alcohol or other medications that can make you drowsy. See also Precautions section.
You may also develop a sudden drop in blood pressure that can cause dizziness, nausea, and fainting. This effect may also increase your risk of a fall. This drop in blood pressure is more likely when you are first starting the medication, when your dose is increased, or when you get up suddenly. To lower your risk, get up slowly from a sitting or lying position. Avoid alcohol.
Rarely, males may have a painful or prolonged erection lasting 4 or more hours. If this occurs, stop using this drug and get medical help right away, or permanent problems could occur.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including:
- rash
- itching/swelling (especially of the face/tongue/throat)
- severe dizziness
- trouble breathing
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Precautions
Before using apomorphine, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients (such as sulfites), which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or pharmacist your medical history, especially of:
- asthma
- heart problems (such as chest pain, heart attack)
- slow/fast/irregular heartbeat (such as arrhythmia)
- mental/mood disorders (such as confusion, hallucinations, psychosis, schizophrenia)
- kidney problems
- liver problems
- symptoms of low blood pressure (such as dizziness, fainting)

Apomorphine may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.
The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using apomorphine, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions:
- certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG)
- family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death)
Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using apomorphine safely.
This drug may make you dizzy or drowsy. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Avoid alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis). See also Side Effects section.
Older adults may be at greater risk for the side effects of this drug, especially falls, hallucinations, and QT prolongation (see above).
During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.
It is unknown if this drug passes into breast milk. Consult your doctor before breast-feeding.
