Read First: Important Safety Information

  • The APOKYN Pen is a medicine delivery device. It is very important that you or your care partner read this Instructions for Use and follow the instructions for using the APOKYN Pen correctly to receive the correct APOKYN dose.
  • Always perform a flow check (prime) before every injection and after loading a new cartridge.
  • The liquid in the APOKYN Cartridge can cause irritation if it gets on your skin or in your eyes. Flush your eyes with cold water and wash the liquid off your skin right away if this happens.
  • The BD pen needle unit is sterile. Avoid contaminating the needle after opening. Do not place it on a surface or touch other items with the needle.
  • Do not dial the dose or try to correct a dialing error with the pen needle in the skin. You could receive the wrong dose.
  • Be careful when removing the needle. Accidental needle sticks can transmit serious infections.

Never store or carry the APOKYN Pen with a pen needle attached.

Storing or carrying the APOKYN Pen with a pen needle attached may let:

  • Air enter the cartridge
  • Medicine leak out

This can affect your APOKYN dose.

Never recap pen with needle attached.

The APOKYN Pen should only be used with pen needles (29G x ½”). These needles are available through your specialty pharmacy provider or your local pharmacy.

You must use a new, sterile BD pen needle with each injection.

How to Use the APOKYN Pen 21

Preparing the APOKYN Pen for Cartridge Loading

Step 1. Remove the gray pen cap by pulling it straight off.

Step 2. Unscrew the teal cartridge holder from the gray pen body by turning it clockwise.

Unscrew the teal cartridge holder - Illustration

Loading a Cartridge

Step 3. Only use APOKYN that is clear and colorless. Do not use an APOKYN Cartridge that contains medicine that is cloudy, green, or contains particles. Call your specialty pharmacy provider for replacement cartridges. Insert the APOKYN Cartridge, metal cap first, into the teal cartridge holder.

Step 4. Lower the gray pen body onto the teal cartridge holder so that the black rod presses against the cartridge plunger. Screw the teal cartridge holder onto the gray pen body. Tighten the pieces by turning the teal cartridge holder counter-clockwise until no gap remains and 1 of the white arrows line up with the white marker on the gray pen body.

Step 5. If you already have a cartridge in the pen and have used the pen, you should check the cartridge through the window in the teal cartridge holder to make sure there is enough APOKYN solution in the cartridge to provide your next dose. If the gray cartridge plunger has reached the red line on the cartridge, remove the cartridge and insert a new cartridge into the pen before attaching the pen needle and preparing the dose.

Check the cartridge - Illustration

Attaching the Pen Needle

Step 6. Remove the pink paper tab from the back of a new pen needle. Use a new needle for each injection. Never reuse needles.

Step 7. Holding the APOKYN Pen by the teal cartridge holder, push the pen needle unit onto the pen. Screw the threaded hub of the pen needle onto the teal cartridge holder counter-clockwise. When the needle unit is attached, remove the outer shield that protects the needle with a gentle pull. Save the outer shield. You will use it to remove the needle from the pen after the injection is finished. Do not remove the inner needle shield at this time. The needle is sterile and must stay clean. After opening, do not place the needle on a surface or let it touch anything.

Attaching the Pen Needle -Illustration

Preparing (Priming) the APOKYN Pen for Use

IMPORTANT Prior to each injection, it is important that the APOKYN Pen be properly primed.

For a new APOKYN Cartridge (1 that has not been used before), repeat the priming procedure described on the next page (Steps 8 9) 3 or 4 times to make sure all the air has been removed from the needle and cartridge.

For an APOKYN Cartridge you have used before (1 that has been previously primed), repeat the priming procedure described on the next page (Steps 8 9) 1 time to make sure all the air has been removed from the needle and cartridge.

Step 8. You must prepare (prime) the APOKYN Pen for use before injecting the medicine. To prime the APOKYN Pen, set the dose by turning the dose knob to 0.1 mL. This is important so you can get rid of any air bubbles in the cartridge.

Step 9. Remove the inner needle shield. Remember, do not let the needle touch anything. With the needle pointing up, firmly push the injection button in as far as it will go and hold for at least 5 seconds. A small stream of medicine must come out of the end of the needle. If it does not, reset the dose by repeating Step 8. Repeat these steps (Steps 8-9) until a small stream of medicine comes out the end of the needle. When medicine comes out of the end of the needle, the APOKYN Pen is primed for injection and ready to use.

APOKYN medicine can cause staining to fabric and other surfaces it touches.

Priming the pen - Illustration

Be careful where you prime the APOKYN Pen.

Setting the Dose

Step 10. To set the dose, turn the white dose knob until the correct dose (number of mLs) is shown in the window. The dose will appear as a red number between two black lines that will line up next to the letters “mL” on the pen body. Make sure the correct number (dose) appears in the window.

Setting the dose -Illustration

Step 11. Dose Correction. If you turn the dose knob past your dose, do not dial backwards. If you dial backwards, APOKYN will be pushed through the needle and you will lose medicine. Continue to turn the dial until it is fully turned. Press the injection button fully. This will reset the dial to zero without pushing medicine out of the needle. Repeat Step 10 to redial your dose.

Dose Correction - Illustration

Giving the Injection

Step 12. APOKYN is only for injection under the skin (subcutaneous injection). Choose an injection site on your stomach area, upper arm or upper leg. Change the site with each injection. Do not inject APOKYN into skin that is red or sore.

Clean the site with an alcohol swab and allow to air dry. Pinch about an inch of skin and fat tissue of your injection site between your thumb and forefinger. With the other hand, insert the needle all the way into the pinched skin.

Step 13. Fully push the teal injection button on the APOKYN Pen. A clicking sound will be heard while the dose is injected. Push the injection button firmly for 5 seconds. Remove the needle from your skin. If medicine keeps dripping from the needle, keep the needle in the skin longer the next time you inject APOKYN.

Giving the Injection - Illustration

IMPORTANT – If you set your dose and cannot depress the teal injection button, the cartridge is empty. Remove the pen needle and cartridge and prepare the pen as described in Steps 2 9 with a new cartridge. Set the dose and give the injection.

If you set your dose and the injection button stops before you receive a complete dose, note the number in the window, remove the pen needle and cartridge, and prepare the pen as described in Steps 2 9 with a new cartridge. Set the dose to the number that last appeared in the window and administer the injection. This completes the dose.

Before attempting to replace a cartridge, be sure that a needle unit is not attached to the APOKYN Pen.

Removing the Pen Needle

Step 14. Carefully replace the outer needle shield. Be careful to avoid a needle-stick. Place the outer needle shield in the notch located on the far left side of your carrying case. The opening of the needle shield should be pointing up. Carefully insert the needle (attached to the pen) into the opening of the shield. Without holding onto the shield, push down firmly.

Removing the Pen Needle - Illustration

Step 15. Hold the pen by the teal cartridge holder and unscrew the pen needle from the cartridge holder. Recap the pen. Never recap the pen with a needle attached. Safely dispose of used pen needles in a “sharps” container. Your specialty pharmacy provider will provide you with a “sharps” container. Do not throw used needles in a trash can.

(apomorphine hydrochloride) Injection

Read this Patient Information before you start using APOKYN and each time you get a refill. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or your treatment.

What is APOKYN?

APOKYN is a prescription medicine used to treat acute, intermittent episodes of poor mobility called “off ” episodes (end-of-dose wearing “off ” or unpredictable “on-off ” episodes) in people with advanced Parkinson's disease (PD).

It is not known if APOKYN is safe and effective in children.

Who should not take APOKYN?

Do not take APOKYN if you are:

  • taking certain medicines to treat nausea called 5HT3 antagonists including, ondansetron, granisetron, dolasetron, palonosetron, and alosetron. People taking ondansetron together with apomorphine, the active ingredient in APOKYN, have had very low blood pressure and lost consciousness or “blacked out.”
  • allergic to apomorphine hydrochloride or to any of the ingredients in APOKYN and experience hives, itching, rash, or swelling (e.g., eyes, tongue, etc.). APOKYN also contains a sulfite called sodium metabisulfite. Sulfites can cause severe, life-threatening allergic reactions in some people. An allergy to sulfites is not the same as an allergy to sulfa. People with asthma are more likely to be allergic to sulfites. Call your healthcare provider if you have hives, itching, rash, swelling of the eyes, tongue, lips, chest pain, trouble breathing or swallowing. See the end of this leaflet for a complete list of ingredients in APOKYN.

What should I tell my healthcare provider before taking APOKYN?

Before you start using APOKYN, tell your healthcare provider if you:

  • have difficulty staying awake during the daytime
  • have dizziness
  • have fainting spells
  • have low blood pressure
  • have asthma
  • are allergic to any medicines containing sulfites
  • have liver problems
  • have kidney problems
  • have heart problems
  • have had a stroke or other brain problems
  • have a mental problem called a major psychotic disorder
  • drink alcohol
  • are pregnant or plan to become pregnant. It is not known if APOKYN will harm your unborn baby.
  • are breastfeeding or plan to breastfeed. It is not known if APOKYN passes into your breast milk. You and your healthcare provider should decide if you will take APOKYN or breastfeed. You should not do both.

Tell your healthcare provider about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements.

Using APOKYN with certain other medicines may affect each other. Using APOKYN with other medicines can cause serious side effects.

Know the medicines you take. Keep a list of them to show your healthcare provider or pharmacist when you get a new medicine.

How should I use APOKYN?

  • Read the Instructions for Use starting on page 6 of this leaflet for specific information about the right way to use APOKYN.
  • Use APOKYN exactly as your healthcare provider tells you to use it.
  • Your healthcare provider will tell you how much APOKYN to use and teach you the right way to use it.
  • Your healthcare provider may change your dose if needed.
  • Do not change your dose of APOKYN or use it more often than prescribed unless your healthcare provider has told you to.
  • Do not give another dose of APOKYN sooner than 2 hours after the last dose.
  • Your healthcare provider will prescribe APOKYN that comes in prefilled glass cartridges that are used with a special multiple-dose injector pen.

  • Keep a record of how much APOKYN you have used each time you inject or your care partner gives you an injection.
  • Use a new needle with each injection. Never reuse a needle.
  • APOKYN is a clear and colorless liquid. Do not use APOKYN if it appears cloudy, colored, or to contain particles, and call your pharmacist.
  • Your healthcare provider may prescribe another medicine called an antiemetic to take while you are using APOKYN. Antiemetic medicines help to decrease the symptoms of nausea and vomiting that can happen with APOKYN.
  • If you take too much APOKYN, call your healthcare provider. If you experience severe or serious side effects such as chest pain or prolonged erection lasting more than 4 hours, go to the nearest hospital emergency room.

What should I avoid while using APOKYN?

  • Do not drink alcohol while you are using APOKYN. It can increase your chance of developing serious side effects.
  • Do not take medicines that make you sleepy while you are using APOKYN.
  • Do not drive, operate machinery, or do other dangerous activities until you know how APOKYN affects you.
  • Do not change your body position too fast. Get up slowly from sitting or lying. APOKYN can lower your blood pressure and cause dizziness or fainting.

What are the possible side effects of APOKYN?

APOKYN may cause serious side effects. Call your healthcare provider right away if you have any of the seriousside effects, including:

  • allergic reaction. An allergic reaction with side effects of hives, itching, rash, swelling (e.g., eyes, tongue, etc.); trouble breathing and/or swallowing may occur after injecting APOKYN.
  • blood clots. Injecting APOKYN into a vein (intravenous) can cause blood clots. Do not inject APOKYN in your vein.
  • nausea and vomiting. Severe nausea and vomiting can happen with APOKYN. Your healthcare provider may prescribe a medicine called trimethobenzamide (Tigan®) to help prevent nausea and vomiting. Some patients can stop taking Tigan after using APOKYN for several months. Some patients may need to keep taking Tigan to help prevent nausea and vomiting. Talk to your healthcare provider before you stop taking Tigan.
  • sleepiness or falling asleep during the day. Some people treated with APOKYN may get sleepy during the day or fall asleep without warning while doing everyday activities such as talking, eating, or driving a car.
  • dizziness. APOKYN can lower your blood pressure and cause dizziness. Dizziness can happen when APOKYN treatment is started or when the APOKYN dose is increased. Do not get up too fast from sitting or after lying down, especially if you have been sitting or lying down for a long period of time.
  • falls. The changes that can happen with Parkinson's disease (PD), and the effects of some PD medicines, can increase the risk of falling. APOKYN may also increase your risk of falling.
  • hallucinations or psychotic-like behavior. APOKYN can cause or worsen psychotic-like behavior includinghallucinations (seeing or hearing things that are not real), confusion, excessive suspicion, aggressive behavior, agitation, delusional beliefs (believing things that are not real), and disorganized thinking.
  • sudden uncontrolled movements (dyskinesias). Some people with PD may get sudden, uncontrolled movements after treatment with some PD medicines. APOKYN can cause or make dyskinesias worse.
  • intense urges. Some people with PD have reported new or increased gambling urges, increased sexual urges, and other intense urges, while taking PD medicines, including APOKYN.
  • heart problems. If you have shortness of breath, fast heartbeat, or chest pain while taking APOKYN, call yourhealthcare provider or get emergency help right away.
  • serious heart rhythm changes (QT prolongation). Tell your healthcare provider right away if you have a change in your heartbeat (a fast or irregular heartbeat), or if you faint.
  • injection site problems. Bruising, swelling, and itching can happen at the site where you inject APOKYN.
  • fever and confusion. This can happen in some people when their PD medicine is stopped or there is a fast decrease in the dose of their PD medicine.
  • skin cancer (melanoma). Some people with PD may have an increased chance of getting a skin cancer called melanoma. People with PD should have a healthcare provider check their skin for skin cancer regularly.
  • tissue changes (fibrotic complications). Some people have had changes in the tissues of their pelvis, lungs, and heart valves when taking medicines called nonergot derived dopamine agonists like APOKYN.
  • prolonged painful erections (priaprism). APOKYN may cause prolonged, painful erections in some people. If you have an erection that lasts more than 4 hours you should call your healthcare provider or go to the nearest hospital emergency room right away.
  • swelling of ankles/legs. APOKYN may cause swelling, especially in the ankles or legs. Tell your healthcare provider if you notice any swelling.

Other common side effects of APOKYN include:

  • yawning
  • runny nose
  • confusion
