For men who cannot use sildenafil or tadalafil, or for whom PDE5 inhibitors have not worked, apomorphine offers a different mechanism with a strong clinical basis. Physician-prescribed through Eros MD.
about Apomorphine
Apomorphine is a dopamine receptor agonist, a medication that works through the central nervous system rather than directly on blood vessels. Unlike sildenafil and tadalafil (which are PDE5 inhibitors that act on vascular smooth muscle in the penis), apomorphine acts on dopamine D2 and D4 receptors in the brain to facilitate the neurological cascade that produces an erection.
In practical terms, this means apomorphine works through a fundamentally different pathway. It activates the brain's role in sexual arousal rather than addressing blood flow mechanics directly. This makes it a genuinely distinct treatment option, not simply a variation of the PDE5 inhibitor class.
Apomorphine is administered sublingually, placed under the tongue, where it dissolves and enters the bloodstream quickly. Onset is typically 20-30 minutes. It does not require sexual stimulation to initiate the neurological response, though arousal enhances effectiveness.
Apomorphine has been used clinically as a dopamine agonist for decades in neurology. Its application in erectile dysfunction has been studied extensively in European markets. It is available by prescription in the US when a physician determines it appropriate.
Why Eros MD prescribes apomorphine
Most online ED platforms offer sildenafil and tadalafil, and that is where they stop. For the majority of men, PDE5 inhibitors are effective and appropriate. But for men who cannot take them, or for whom they have been inadequate, those platforms have nothing to offer. Apomorphine reflects Eros MD's commitment to whole-patient care, not a gimmick, just medicine.
who it is for
Apomorphine is not the right first-line option for every man with ED. For specific clinical profiles, however, it is the best available treatment. Your Eros MD provider determines eligibility during your assessment by evaluating your cardiovascular profile, current medications, and prior ED treatment history.
Important Note
Apomorphine eligibility is determined by a licensed Eros MD physician. Not every patient will qualify. The provider evaluates contraindications and determines whether apomorphine is appropriate for your specific health profile.
Men who cannot take PDE5 inhibitors due to nitrate medications (nitroglycerin, isosorbide dinitrate) or other cardiovascular conditions that make sildenafil or tadalafil unsafe.
Men who did not achieve adequate response from PDE5 inhibitors at appropriate doses, where a different mechanism may produce a better outcome.
Men under physician evaluation for complex ED with multiple contributing factors, or who prefer a centrally-acting mechanism over vascular support.

the fine print
Common Side Effects
Nausea (most common, typically mild and dose-dependent, often resolves with continued use)
Dizziness or light-headedness
Yawning
Sleepiness (less common)
Nausea is typically manageable. Starting at a lower dose and titrating upward under physician guidance reduces likelihood and severity.
Serious Considerations
Apomorphine requires careful screening: cardiovascular profile, current medications, and prior PDE5 experience all factor in. Not recommended for men with severe orthostatic hypotension or unstable cardiovascular disease. Seek immediate medical attention for any erection lasting more than 4 hours.
Eros MD Safety Process
Apomorphine requires physician assessment and prescription. Do not use without medical supervision. Your Eros MD provider evaluates your health history, current medications, and suitability before prescribing, and walks you through safe initiation.
How it works
Because apomorphine is prescribed for specific clinical profiles, the physician evaluation is central. Here is what to expect:
Complete your confidential assessment, covering symptoms, medical history, current medications, prior ED treatments, and goals. About 10 minutes.
A licensed physician reviews your intake and evaluates whether apomorphine is the right fit, typically after understanding why PDE5 inhibitors are not appropriate or not working well.
If prescribed, your apomorphine is dispensed by a licensed U.S. pharmacy with detailed instructions on sublingual administration and safe initiation.
Your medication is delivered in discreet, unmarked packaging.
Your provider is available for follow-up: first-dose questions, dose titration, and ongoing monitoring.
Questions worth asking
Apomorphine is a dopamine receptor agonist with a range of clinical applications. For erectile dysfunction, it works through a central nervous system mechanism, distinct from PDE5 inhibitors like sildenafil and tadalafil, to facilitate the neurological signals that produce an erection.
Unlike PDE5 inhibitors (sildenafil, tadalafil), apomorphine is not contraindicated with nitrate medications. This is one of the primary reasons it may be prescribed for men on nitrate therapy for heart conditions. Your provider will evaluate your complete medication list to confirm compatibility.
Clinical evidence supports apomorphine as an effective treatment for ED, particularly for men with psychogenic or mixed-cause erectile dysfunction. Efficacy rates in clinical studies are generally lower than PDE5 inhibitors in unselected populations. For appropriately selected patients, particularly those with central or neurological contributing factors, response can be meaningful. Your provider will discuss realistic expectations based on your profile.
The most common side effect is nausea, typically mild and dose-dependent. Other reported side effects include dizziness, yawning, and occasional sleepiness. Side effects are generally manageable, especially with proper dose titration under physician guidance.
Apomorphine requires a prescription in the United States. Eros MD is one of the few online platforms where a licensed physician can evaluate your case and prescribe apomorphine if it is determined to be appropriate and safe for you.
