Methylstenbolone + Ketorolac Tromethamine

Ketorolac Tromethamine brand names: Toradol, Acuvail.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Methylstenbolone and Ketorolac Tromethamine in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Methylstenbolone and Ketorolac Tromethamine

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Ketorolac Tromethamine and Methylstenbolone in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Methylstenbolone at all — not against Ketorolac Tromethamine, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

What to actually watch for

No Interaction Found — But Data Suggests Methylstenbolone and Ketorolac Tromethamine May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

  • Liver problems Worth acting on Additional detail

    Methylstenbolone

    “Orally, methylstenbolone is possibly unsafe. As an anabolic androgenic steroid, there is concern that it might cause serious side effects including heart disease and liver injury.”

    Methylstenbolone · Natural Medicines adverse-effect record, reported in cardiovascular disease (cvd).

    “There is a case of cholestatic jaundice with elevated liver enzymes, dark urine, clay stools, and pruritus in a 26-year-old male, likely related to the use of a product (Super DMZ Rx 2.0) containing methylstenbolone 10 mg and dymethazine 10 mg per capsule. The product was used at manufacturer-recommended doses of two capsules daily for up to 1 month. Liver enzyme levels gradually decreased after discontinuation.”

    Listed in the ADVERSE REACTIONS section of the FDA label for Ketorolac Tromethamine. Read the label on DailyMed ›

Reported for Methylstenbolone but not commonly for Ketorolac Tromethamine: itching and yellowing of the skin or eyes.

Effects for Ketorolac Tromethamine come from the ADVERSE REACTIONS section of its FDA label; effects for Methylstenbolone come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 5,598 voluntary FDA FAERS reports for Ketorolac Tromethamine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

About Methylstenbolone

What is Methylstenbolone?

  • Muscle building (bodybuilding)
  • Strength gains
  • Body recomposition
  • Athletic performance enhancement

Methylstenbolone is a synthetic, oral anabolic-androgenic steroid that has been sold in some 'prosteroid' or 'designer supplement' products, not a natural herb. It is not an approved or safe dietary supplement, it carries real risks including serious liver damage, and it is banned in sports and prohibited in many countries. We strongly recommend against using it and urge you to speak with a doctor or pharmacist first.

Synthetic compound (not derived from a plant) · Capsules, tablets

An interaction check asks whether these two react with each other — it does not ask whether Methylstenbolone is a good idea for someone in your situation. Here is what our Methylstenbolone record says about it on its own.

Methylstenbolone: dosing

There is no established, safe, or approved dose for methylstenbolone. It is not a recognized medicine or legitimate dietary supplement, so no medical dosing guidance exists.We will not provide dosing amounts because doing so could encourage harmful use. If you have taken a product that contains methylstenbolone, stop and talk with a healthcare professional. Never assume a product is safe just because it is sold online or in a store.

About Ketorolac

What Is Ketorolac Used For?

Brand names: Toradol, Acuvail

Ketorolac is used for short-term management of moderately severe acute pain — the kind that would otherwise require an opioid-level painkiller. It is most commonly used in a postoperative (after surgery) setting.

Treatment is always started with an injection (IV or IM), and oral tablets are only used as a follow-up if needed. The total treatment time — shots plus pills combined — must never exceed 5 days. It is not meant for minor aches or long-term pain conditions.

Most-Reported Side Effects for Ketorolac Tromethamine

From FAERS, the FDA’s public side-effect reporting system (5,598 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Drug hypersensitivity 329 reports
Nausea 295 reports
Headache 284 reports
