Used for Parkinson's Disease
Vyalev (foscarbidopa / foslevodopa) is used to treat movement problems in adults with advanced Parkinson's disease (PD). It's given as a continuous infusion under the skin of the stomach using the Vyafuser pump. This anti-Parkinson medication helps raise and keep dopamine levels high in the brain. Side effects can include hallucinations and uncontrolled movements. It can also cause skin reactions where the medication is infused.

What is Vyalev (foscarbidopa / foslevodopa) used for?
- Advanced Parkinson’s disease (PD)
How Vyalev (foscarbidopa / foslevodopa) works
Vyalev contains two medications: foscarbidopa and foslevodopa. In the body, they turn into carbidopa and levodopa, which work together to raise dopamine levels in the brain. This helps relieve symptoms of Parkinson's disease (PD).
- Levodopa is a dopamine replacement. It travels to the brain, where it's converted into dopamine. By restoring dopamine levels in the brain, levodopa helps relieve PD symptoms.
- Carbidopa is a dopa decarboxylase inhibitor. Dopa decarboxylase is a protein that breaks down levodopa before it can reach the brain. Blocking this protein lets more levodopa reach the brain and turn into dopamine. This means more levodopa and dopamine stay in the brain longer. This helps improve PD symptoms.

Pharmacist tips for Vyalev (foscarbidopa / foslevodopa)
- Vyalev (foscarbidopa / foslevodopa) is infused continuously over 24 hours using the Vyafuser pump. The Vyfuser pump comes separately from the medication. Be sure you have all the supplies you need for the infusion.
- Before using Vyalev (foscarbidopa / foslevodopa), your healthcare team will teach you or your caregiver how to use the medication with the Vyafuser pump. Carefully read the instructions for use for Vyalev and the Vyafuser pump. Call your prescriber or your care team if you have any questions.
- How to store Vyalev (foscarbidopa / foslevodopa): Store the medication vials in the refrigerator in the original carton. Don't let the medication freeze, though. If needed, you can keep the vials at room temperature up to 86ºF for up to 28 days. But once it's reached room temperature, don't put it back in the fridge. If you take a vial out of the fridge, write the date down on the carton so you know when to throw it away.
- Before using each Vyalev (foscarbidopa / foslevodopa) vial: Take it out of the refrigerator and let it reach room temperature for 30 minutes. If it isn't at room temperature when you use it, you might not get the correct amount of medication. Don't warm it up any other way, like microwaving or running under hot water.
- Where to infuse Vyalev (foscarbidopa / foslevodopa): Infuse the medication under the skin on the stomach, 2 inches away from your belly button. At least every 3 days, move the infusion site 1 inch from areas you've used within the last 12 days. This helps your skin heal. Don't infuse into tender, red, bruised, or hard skin.
- How to fill the syringe with Vyalev (foscarbidopa / foslevodopa) and place it into the Vyafuser pump: Your care team will show you how to draw the medication up from the vial into the syringe to fill your pump. Don't use the medication if it's been in the syringe for more than 24 hours. Follow your care team's steps to connect the infusion tubing to the syringe and place the syringe into the pump.
- When to change your Vyalev (foscarbidopa / foslevodopa) infusion set tubing: Talk to your prescriber about how often to change your infusion set tubing. It can stay in place for up to 3 days when you infuse the medication continuously.
- Stopping the Vyalev (foscarbidopa / foslevodopa) infusion for a short amount of time: You can stop the infusion for a short amount of time, like when you take a shower. But if you stop it for more than 1 hour, you'll need to use a new infusion set (the cannula and tubing) when you start it again. Also choose a different spot on your stomach for the infusion.
- If you need to stop the Vyalev (foscarbidopa / foslevodopa) infusion for more than 3 hours: If you stop the infusion for more than 3 hours, you might need a loading dose to help control your symptoms. Ask your prescriber what to do, whether you need a loading dose, and how much medication to take.
- Keep a back-up supply of carbidopa-levodopa pills: Make sure to have some extra carbidopa-levodopa pills like Sinemet that you can take by mouth. This is helpful in case the Vyafuser pump stops working or if you take the pills for loading doses. Ask your prescriber how to take the pills if needed.
- Don't drive or do anything that needs your full attention until you know how Vyalev (foscarbidopa / foslevodopa) affects you. This medication can make you sleepy and might even make you fall asleep suddenly.
- Keep an eye on the infusion sites you use for Vyalev (foscarbidopa / foslevodopa). Watch for skin redness, swelling, tenderness, soreness, bruising, bleeding, or rash.

- Watch for unusual numbness, tingling, or confusion while taking Vyalev (foscarbidopa / foslevodopa). Also look out for changes like a sore or red tongue, or cracks at the corners of your mouth.
