Why Would a Trimix Injection Be Needed?

Trimix injections are needed to treat erectile dysfunction, or ED, according to the Memorial Sloan Kettering Cancer Center. Trimix is a combination of three medicines injected directly into the penis in a procedure called penile injection therapy. The injection combines alprostadil, phentolamine and papaverine. Trimix injections work best if administered roughly 5 to 15 minutes before sex.

No one should use the ED medications Viagra, Levitra or Stendra on the morning of taking a Trimix injection or on the night before, says the Memorial Sloan Kettering Cancer Center. Cialis is safe to take in this time frame if the dose is limited to 5 milligrams. Patients can self-administer Trimix at home if trained by qualified nurses or nurse practitioners. This training typically requires two separate office visits.

Trimix creates an erection by relaxing the penis muscle and causing its blood vessels to open up. It can take anywhere from two to six injections to identify the correct dose of Trimix. Users should consult with their health providers before upping their dosage levels. It is only safe to take one dose of Trimix in any 24-hour period. Patients should store Trimix in a refrigerator and ensure the medicine stays away from light. People should never use Trimix that has expired.
