Methoxydienone and Dorzolamide, Timolol

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 Dorzolamide, Timolol and Methoxydienone 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 Methoxydienone at all — not against Dorzolamide, Timolol, 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.

See Every Supplement That Interacts With Dorzolamide, Timolol

This page covers Methoxydienone only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Dorzolamide, Timolol page lists 71 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Indian Snakeroot (major), 1,3-dmaa (moderate), Acacia Rigidula (moderate), Active Hexose Correlated Compound (ahcc) (moderate) and Ayahuasca (moderate).

By severity: 1 major · 59 moderate · 11 minor.

From our pharmacist’s overview on the Dorzolamide, Timolol page

“Indian snakeroot is the one entry here I would treat as a genuine hazard with Cosopt (dorzolamide and timolol), the glaucoma eye drop. Its reserpine content plus a beta-blocker like timolol could slow the heart or drop blood pressure too far, and it holds the only major rating among the 71 supplements and herbs on file.”

About Methoxydienone

What is Methoxydienone?

  • Muscle building
  • Strength gains
  • Bodybuilding supplement stacks
  • Athletic performance

Methoxydienone is a synthetic steroid-like compound marketed in some bodybuilding and 'prohormone' supplements, not a natural herb. There is very little reliable human safety or effectiveness research, and steroid-related products carry real risks to the liver, hormones, and heart. We do not recommend it, and you should talk with a doctor or pharmacist before using any product that contains it.

Synthetic compound (not a plant part) · Capsules, tablets, powders (often as part of 'prohormone' or bodybuilding blends)

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

Methoxydienone: dosing

There is no established or safe dose of methoxydienone. It has not been tested in proper clinical trials to determine a recommended amount.Supplement labels that include it may suggest a dose, but these are not backed by solid safety research and product contents may be inaccurate. We do not provide a dose for it.The safest choice is to avoid it.
