Neupro is a prescription medicine used to manage Parkinson’s disease and restless legs syndrome, and questions about how it affects erections are common. Some people using apomorphine, the active ingredient in Neupro, report changes in erections, including prolonged or painful erections, which may require medical attention. This article explains what is known from clinical data and safety reports, describes common side effects, and outlines when to contact a healthcare professional. The information below can help you discuss risks and benefits with your doctor and make informed decisions about using Neupro safely.
What Is Neupro and How Is It Used
Neupro is a brand name for apomorphine, a dopamine agonist delivered through a skin patch. It is prescribed for Parkinson’s disease to improve tremor, stiffness, and slowness, and for moderate to severe restless legs syndrome. Apomorphine affects chemicals in the brain, particularly dopamine pathways, which can influence movement, mood, and sexual function. While it is not primarily used for erectile dysfunction, changes in erections are noted in safety communications and labeling. Continued use under medical supervision is important, and any concerns about sexual side effects should be discussed with a clinician.
Common Side Effects of Neupro
Like many prescription medicines, Neupro can cause side effects, and some are more common than others. Most people experience mild to moderate reactions, especially when starting treatment or adjusting the dose. Being aware of these effects can help you recognize when to reach out to a healthcare professional.
Most Frequently Reported Side Effects
- Nausea and vomiting
- Drowsiness or sleepiness
- Application site reactions such as redness, itching, or rash
- Dizziness or lightheadedness
- Headache
Potential Serious Side Effects
Some side effects are less common but more serious. These include sudden sleep attacks, low blood pressure, hallucinations, and compulsive behaviors such as gambling or binge eating. In rare cases, people using apomorphine have reported problems with erections that are prolonged or painful. These events should be treated as urgent, and medical help should be sought right away if they occur.
Priapism and When to Seek Medical Care
Priapism means a lasting and often painful erection unrelated to sexual activity. It is considered a medical emergency because it can damage tissues and affect long-term function. While priapism is not one of the most common side effects of Neupro, there are case reports involving apomorphine. If an erection lasts more than four hours, causes significant pain, or interferes with daily life, seek emergency medical care without delay.
Clinical Data and Label Information
Regulatory labels and safety communications summarize reported side effects, including those that are rare. These documents are updated as new information becomes available from clinical trials and postmarketing reports. The following table summarizes key data points related to erections and Neupro use where available.

How to Discuss Neupro With Your Healthcare Provider
Open communication with your clinician can help you balance the benefits and risks of Neupro. Bring a complete list of your current medicines, including over-the-counter products and supplements, as interactions can affect side effects. Describe any personal or family history of heart conditions, mental health disorders, or substance use. If you experience changes in erections or other concerning symptoms, ask whether dose adjustment, monitoring, or alternative treatments might be appropriate for you.
Reliable Information and Support Resources
Pediatric and adult care teams, movement disorder specialists, and pharmacists can provide personalized guidance. Official labeling, summaries of product characteristics, and peer-reviewed publications are trustworthy sources for ongoing updates. Patient support organizations and reputable health websites can help you prepare questions for appointments and understand when additional evaluation is needed. Using verified sources reduces confusion and supports safe use of Neupro.
