Treatment and safety

What is TriMix and when is it considered?

TriMix is a compounded injectable combination used for erectile dysfunction. It is not an FDA-approved combination product, and it is generally considered only when other approaches have not worked or are not appropriate.

TriMix refers to a compounded preparation combining vasoactive medications administered by injection. Some individual components have FDA-approved intracavernosal products; the combination itself is compounded and has not been reviewed and approved by FDA as a combination product. That distinction should always be stated plainly.

In guideline terms, injectable therapy sits further along the treatment pathway. It comes up when oral PDE5 inhibitors have failed, are contraindicated, or are not tolerated, and when a man has been properly evaluated and counselled about what is involved.

It requires in-person instruction, careful supervision and a clear plan for what to do if an erection does not resolve. This page deliberately gives no dosing or injection technique — that belongs in a supervised clinical setting, not on a website.

Risks and limitations

  • Compounded combinations are not FDA-approved and are not reviewed for safety, effectiveness or quality before marketing.
  • Risks include prolonged erection and priapism, penile pain, bruising, and scarring or fibrosis over time.
  • Not appropriate for men with certain conditions or on certain medications.
  • Requires supervised training and an explicit emergency plan.
  • This page does not state which therapies MMI stocks or offers.

Later-line options need a proper conversation

If oral treatment has not worked, an evaluation can clarify what else is reasonable.
