Penile Injection Therapy: How Tri-Mix Injections Work

Tri-Mix Injections: A Compounded Penile Injection Therapy for Men Who Haven't Responded to Oral ED Medications

Disclaimer: Tri-Mix is a compounded medication prepared by a licensed pharmacy based on an individual prescription. It is not an FDA-approved combination product. The FDA has not evaluated it for safety, effectiveness, or quality. All prescription therapies require evaluation and prescription from a licensed medical provider.

 

Tri-Mix is a compounded penile injection therapy that may help appropriate patients achieve and maintain erections. It is not FDA-approved, and individual results vary and require provider evaluation. Tri-Mix is a compounded combination of three vasodilators prepared by a licensed compounding pharmacy based on an individual prescription: Papaverine, Phentolamine, and Prostaglandin. These agents work together to increase blood flow directly to the penis. It is not FDA-approved as a combination product.

Unlike oral ED medications, penile injections bypass the digestive system, offering fast-acting results within minutes of administration. Injected directly into the base or side of the penis using a tiny needle, Tri-Mix is discreet, customizable to each man's needs, and may be considered for appropriate patients who have not responded to oral ED medications, following evaluation by a licensed provider. With proper guidance from a men’s health specialist, Tri-Mix may help support confidence and sexual performance for appropriate patients under medical supervision.

What Is In Tri-Mix?

Below is a breakdown of the different vasodilators and how they function after injection:

 

Papaverine & Phentolamine

These are two separate drugs that cause blood vessels to expand. When the two drugs are injected into the penis, they produce an erection by increasing blood flow to the penis. When used in combination alone, they are called a bi-mix.

Prostaglandin E-1

A potent hormone-like substance that can control blood pressure, muscle contractions, and inflammation.

Injecting Tri-Mix

Tri-Mix is injected directly into the corpus cavernosum (one of the two chambers of erectile tissue in the penis) using a fine, short needle.

Many men may experience results within minutes of injection. Response rates and timing vary by patient, dosage, and formulation. Talk to your provider about what to expect; dosage may be adjusted based on provider evaluation. Duration of response varies by patient. It’s important to note that Tri-Mix injections do not interfere with the ability to achieve orgasm.

If you are experiencing an erection lasting longer than 3 hours, call 911 or go to the nearest Emergency Room. Priapism is a medical emergency and requires immediate attention.

Other risks of penile injection therapy include: injection-site pain, bruising, hematoma, dizziness, low blood pressure, scarring (penile fibrosis) with long-term use, and priapism. Dosage must be set and supervised by a licensed provider.
