Male Enhancement Supplements and Your Medications: What to Ask
Supplements can interact with prescription medicines, and the label rarely tells you how. The dangerous pair is a nitrate for chest pain with an ED drug, which can drop blood pressure sharply. Tell your doctor and pharmacist about every supplement, tell your surgeon well before an operation, and keep taking prescribed medicine unless a clinician says otherwise.

The basic risk01
Can male enhancement supplements interact with prescription drugs?
Yes. Natural does not mean safe with your medicines.
The National Center for Complementary and Integrative Health says supplements can interact with medicines, and gives St. John's wort as an example (NCCIH, Using Dietary Supplements Wisely). It also warns that “natural” does not always mean “safe”, and that companies are responsible for the evidence that their products are safe (NCCIH, Using Dietary Supplements Wisely). The FDA generally cannot review supplements for safety or effectiveness before sale (NCCIH, Using Dietary Supplements Wisely) (FDA, Q&A on dietary supplements).
Two things make male enhancement products a special case. They are taken by men who often use heart, blood pressure and diabetes medicines (NIDDK, ED causes). And the category has a record of products with hidden drugs, which no label warns about (NCCIH, Using Dietary Supplements Wisely) (FDA, X10 hidden-drug notice).
Do not drop or change a prescription because of a supplement, or because of anything you read here. Call your doctor or pharmacist first. NIDDK says not to stop any medicine on your own (NIDDK, ED treatment).
Stallion Power is a dietary supplement. It is not a drug, and the label asks anyone taking medications or with a medical condition to consult a doctor before use.
The dangerous pair02
Why is combining nitrates with ED drugs dangerous?
Nitrates and ED drugs both lower blood pressure. Together they can lower it to dangerous levels.
MedlinePlus says not to take sildenafil with nitrates for chest pain, which include isosorbide dinitrate, isosorbide mononitrate and nitroglycerin, or with “poppers” such as amyl nitrite (MedlinePlus, Sildenafil). The American Heart Association says ED medicines should not be used with nitrate therapy for chest pain from coronary artery disease, and that nitrates should not be given within 24 to 48 hours after an ED drug, depending on the drug (AHA, Sexual activity and heart disease).
This matters for supplements because some products sold for sexual enhancement have contained sildenafil and tadalafil that the label never listed. The FDA warned in May 2026 about one such product, and said the hidden drugs may interact with nitrates and lower blood pressure to dangerous levels (FDA, X10 hidden-drug notice). The FDA adds that men with diabetes, high blood pressure, high cholesterol or heart disease often take nitrates (FDA, X10 hidden-drug notice).
We have no evidence that Stallion Power holds a hidden drug, and no lab result for it either. If you take a nitrate, still talk to your doctor before any enhancement product. Our guide to tainted products explains the problem.
Blood pressure03
Do supplements interact with blood pressure medicine?
Some can. The table lists what the public sources say about each Stallion Power ingredient. Read it as a list of questions for your pharmacist, not as proof that a gummy causes a problem. The label gives no amount for any ingredient, and the sources do not say these effects occur at gummy-sized amounts.
| Ingredient | Flag in the sources |
|---|---|
| L-arginine | May temporarily lower blood pressure, so additive effects with blood pressure medicines are possible (MSK, Arginine) |
| Ashwagandha | Possible interaction with thyroid hormone, diabetes and blood pressure medicines, sedatives and anticonvulsants; not recommended before surgery (NCCIH, Ashwagandha) |
| Tribulus | Listed interactions include diuretics, blood pressure medicines, diabetes medicines and clopidogrel; clinical relevance unknown (MSK, Tribulus terrestris) |
| Green tea extract | High doses of green tea can lower blood levels of nadolol; extract can lower atorvastatin levels (NCCIH, Green tea) |
| Horny goat weed | MSK says not to take it with heart disease; Drugs.com lists no well-documented interactions (MSK, Epimedium (horny goat weed)) (Drugs.com, Horny goat weed) |
| Maca | May interfere with testosterone lab tests; a losartan effect is from rats only (MSK, Maca) |
| Muira puama | No well-documented interactions, but information is lacking (Drugs.com, Muira puama) |
| Catuaba | We found no interaction data |
| Caffeine (5 mg) | FDA cites 400 mg a day as generally not linked to harm in most healthy adults; too much can raise heart rate and blood pressure (FDA, Caffeine) |
The ceilings on the ingredients page show how small each line must be. A small amount may carry little risk, but only a pharmacist who sees your whole list can say. A person on blood pressure medicine should ask before starting.
Blood thinners04
Can herbal supplements affect blood thinners?
Possibly, and the evidence is thin. In the sources we read, tribulus is listed with a possible interaction with clopidogrel, and stent thrombosis was reported with an herbal formula that contained it (MSK, Tribulus terrestris). Green tea extract can lower atorvastatin levels (NCCIH, Green tea). We found no source that addresses warfarin and the Stallion Power herbs, so we will not guess.
The safe route is simple. If you take a blood thinner, show your pharmacist the full Supplement Facts panel before the first gummy. Our side effects page covers the label warnings.
Before an operation05
Should I stop supplements before surgery?
Tell your surgical team, and tell them early. NCCIH says to tell providers about supplements before surgery as far in advance as possible, because some raise bleeding risk or affect anesthesia (NCCIH, Using Dietary Supplements Wisely). Its ashwagandha fact sheet does not recommend ashwagandha before surgery (NCCIH, Ashwagandha).
The sources do not give a number of days to stop each supplement, so we will not give one. The surgeon or anesthesiologist decides. Do not stop any prescribed medicine for an operation unless they tell you to.
- Bring the bottle or a photo of the Supplement Facts panel.
- Mention every product, including gummies, teas and powders.
- Ask what to do with each one, and write down the answer.

How do I tell my pharmacist what supplements I take?
NCCIH advises telling all your health care providers about every supplement you use (NCCIH, Using Dietary Supplements Wisely). A pharmacist is often the quickest place to ask. Use this list.
- Write down the name. Use the exact product name, such as Stallion Power, and the serving: 1 gummy once daily.
- Show the panel. The nine blend lines, the 82 mg blend total and 5 mg of caffeine are what a pharmacist needs.
- Name your medicines. Include prescriptions, over-the-counter drugs and other supplements.
- Name your conditions. Heart, blood pressure, diabetes, thyroid and liver conditions matter most here.
- Ask directly. Is it safe with my medicines? Should I wait until after a test or an operation?
The label says consult your doctor if you are pregnant or nursing, taking medications or have a medical condition, and to stop use and consult your doctor if any adverse reaction occurs.
Know the signs07
When to get care right away
Chest pain, fainting, an erection lasting longer than four hours, or sudden vision or hearing loss need care right away (NIDDK, ED treatment) (MedlinePlus, Sildenafil).
Say which products and medicines you took. If you used an ED drug and a nitrate, tell the emergency team both names. The FDA invites reports of adverse events through MedWatch (FDA, X10 hidden-drug notice).
