Most apomorphine side effects are mild and fade as the body adjusts, including nausea, dizziness, and drowsiness. The side effect that matters most is a drop in blood pressure, which is why low doses, a slow start, and medical screening are standard practice.
Apomorphine works differently than a typical ED medication, and its side effects reflect that. Because it acts on dopamine pathways in the brain instead of blood vessels alone, the side effect profile looks a bit different from a standard PDE5 inhibitor. Here's what's common, what's less common, and what should prompt a call to your provider.
Common Apomorphine Side Effects
Most side effects are mild, dose-related, and most likely during the first few doses while the body adjusts. They tend to ease with continued use, especially at the lower doses used in combination formulas like Performax.
- Nausea: The most frequently reported side effect. Apomorphine was originally developed as an emetic, so some nausea isn't unexpected, especially at higher doses.
- Dizziness: Usually tied to its effect on blood pressure, particularly when standing up quickly.
- Drowsiness: Some men feel unusually sleepy shortly after dosing.
- Yawning: An unusual but well-documented effect linked to apomorphine's action on dopamine receptors.
- Headache or mild oral irritation: Since sublingual formulas dissolve under the tongue, some men notice mild tingling or discomfort at the dosing site.
Why Apomorphine Can Lower Blood Pressure
This is the side effect worth understanding most. Apomorphine can cause a dose-related drop in blood pressure, including orthostatic hypotension, a blood pressure dip that happens specifically when standing up. FDA-reviewed data shows measurable, dose-dependent blood pressure decreases with apomorphine, and in trials among Parkinson's patients, roughly 1 in 10 experienced orthostatic hypotension, low blood pressure, or fainting, according to the FDA-approved prescribing information.
That's a major reason apomorphine for ED is usually prescribed at a low dose alongside a PDE5 inhibitor rather than alone at a higher one. It's also why a provider asks about blood pressure medications, heart conditions, and any history of fainting before prescribing it. Combining apomorphine with alcohol, nitrates, or other blood-pressure-lowering medications raises that risk further, which is one reason alcohol and ED medications don't mix well (link to new blog: Does Alcohol Cause Erectile Dysfunction?).
Common vs. Serious Apomorphine Side Effects
Can You Take Apomorphine Every Day?
No, and it isn't prescribed that way. Apomorphine-based formulas like Performax are on-demand medications, taken before sex, not on a daily schedule. Providers typically cap frequency, often no more than once every 48 hours, partly because of how the blood pressure effects can add up with more frequent dosing.
Who's at Higher Risk for Apomorphine Side Effects
- Men with existing low blood pressure: Apomorphine's blood-pressure-lowering effect can be more pronounced if you already run low.
- Men taking blood pressure medications: Combining apomorphine with antihypertensives or nitrates can compound the drop significantly.
- Men with a history of fainting: A prior episode of syncope makes it more likely to happen again with a medication that affects blood pressure.
- Men who drink alcohol around dosing: Alcohol intensifies apomorphine's blood-pressure-lowering effect, raising the risk of dizziness or fainting.
This is exactly why a provider reviews your full medical history, including current medications, before prescribing apomorphine in any form. Starting with a half dose is standard for new patients too, so you and your provider can see how your body responds before moving to a full dose.
What Your Provider Checks Before Prescribing Apomorphine
Before apomorphine ends up in a prescription, a provider reviews blood pressure history, current medications including nitrates and antihypertensives, any history of fainting or heart conditions, and how often you drink. That review is what allows a low, combined dose to stay effective while being much easier to tolerate than the higher standalone doses used decades ago in the original Uprima formula.
Apomorphine Side Effects FAQ
Does apomorphine cause nausea for everyone?
No, but it's the most commonly reported side effect, especially at higher doses or the first few uses. It tends to ease with continued, lower-dose use.
Can apomorphine cause fainting?
Yes, in a minority of patients, usually tied to its blood pressure effect. That's exactly why screening for blood pressure history and starting slow are standard.
Do side effects get better over time?
For most men, yes. Side effects tend to be most noticeable in the first few doses and ease as the body adjusts, especially at the lower combination doses.
When should I call my provider about a side effect?
Call promptly for fainting, chest pain, persistent or severe dizziness, or any changes to vision or hearing. Seek immediate medical attention for an erection lasting more than four hours.
Ask Your Provider If Performax Is Right for You
Knowing what side effects to expect is part of deciding whether an apomorphine-based formula makes sense for you. A Mavrox provider reviews your full medical history before prescribing Performax and stays available if any side effects or questions come up.
