Trimix combines three medications used to treat erectile dysfunction (ED). Phentolamine, papaverine, and alprostadil synergistically increase blood flow into the penis to help men get and maintain an erection. They have different pharmacological properties so that you can get the greatest benefit with the least risk of side effects. Penile injections, also called intracavernosal injections, are a safe and effective ED treatment option.
Many men prefer injectable medications to treat ED because they have experienced side effects when using oral medications, or these medications did not work well for them. In fact, 70% of men surveyed highly rate their satisfaction with injectable ED medications. Research suggests that Trimix is over 95% effective for treating ED.1 Trimix is drawn into an insulin syringe and injected into the penis using a very small insulin needle.
Trimix is a compound that is prepared in a compounding pharmacy. The medications in this compound can break down over time and lose their effectiveness. Each vial of Trimix should be marked with a “beyond-use” date, indicating when the medication is no longer considered to be effective. Beyond-use dates mean the same as expiration dates.
Medications have a beyond-use date to indicate when they should no longer be used. In some cases, this is because the drug components have broken down and are no longer considered to be fully effective, and in others, the product may have changed chemically or become contaminated.
Improperly stored Trimix or Trimix beyond its use date will break down and no longer be effective. You should not use Trimix after its beyond-use date.
Yes, Trimix will lose its effectiveness over time. This process is faster if Trimix is left out of the refrigerator for any length of time, or refrigerated, instead of frozen, when you want to keep it for over a month. When traveling, store your Trimix in a cooler with ice packs.

Trimix loses its effectiveness over time, especially if it is not refrigerated. Alprostadil, especially, is the limiting factor in Trimix stability. Stability testing has been completed on various strengths of Trimix ingredients, including alprostadil 5 µg/mL to 45 µg/mL, papaverine 15 mg/mL to 30 mg/mL, and phentolamine 0.4 mg/mL to 5 mg/mL, and a single-strength preparation containing alprostadil 30 µg/mL, papaverine 30 mg/mL, and phentolamine 2 mg/mL. For testing, these medications were compounded and stored in two different settings. Beyond-use dates of 60 and 64 days were obtained when Trimix was frozen at -20 degrees Celsius and 30 days when it was refrigerated at 4 degrees Celsius.
For Trimix preparations from Invigor Medical, patient and pharmacy history has shown that Trimix is effective frozen for up to six months and usable in the refrigerator for longer than the 28 days stated on the label. This agrees with the research that reports that alprostadil becomes less effective over time, losing about 6% of its effectiveness at one month refrigerated and 11% at two months and pharmacist recommendations.
When used as directed, Trimix is safe for most men. Potential side effects from Trimix include:
Other potential side effects include:
If you inject too much Trimix or inject Trimix more often than directed, you increase your risk for priapism and penile scarring.
It is important to not inject Trimix more than once every 24 hours. Most doctors will also recommend not injecting Trimix on more than two consecutive days or more than three times in a week.
