Is Trimix FDA-Approved?
No. Trimix is a compounded medication made for one patient from a prescription, and it is not FDA-approved. The FDA does not verify the safety, effectiveness or quality of compounded drugs before they reach patients. Caverject® and Edex® are FDA-approved products, and they are different products from Trimix.
Key facts
- Trimix is compounded and is not FDA-approved.
- The FDA does not verify the safety, effectiveness or quality of compounded drugs before they are marketed.
- A compounded drug is made for an individual patient from a prescription.
- Caverject® and Edex® are FDA-approved injections of alprostadil alone. They are different products from Trimix.
- No standardized injected mixture for ED is FDA-approved, so these mixtures have to be compounded.
Why isn't Trimix FDA-approved?
FDA approval belongs to a specific product from a specific manufacturer, after that company has shown its safety and effectiveness. Trimix is not a manufactured product. It is a mixture a compounding pharmacy prepares from a prescription, so there is no approved Trimix to buy. The American Urological Association guideline notes that no standardized mixture is FDA-approved, which is why these combinations have to be compounded. The papaverine label goes further and says papaverine is not indicated for injection into the penis.
What does not FDA-approved mean for you?
The FDA says it does not verify the safety, effectiveness or quality of compounded drugs before they are marketed. It also warns that poor compounding practices can cause serious quality problems, such as contamination or too much or too little of a medicine.
The FDA's position is that compounded drugs should only be used in patients whose medical needs cannot be met by an FDA-approved drug. That is a question to raise with your provider, who decides what fits.
Is Trimix legal?
Compounding is legal when federal and state conditions are met, including a valid prescription for an individual patient. Trimix sold without a prescription, or from a seller with no licensed pharmacy behind it, is a different matter.
Before you order, check that the seller requires a provider evaluation and a prescription, and uses a licensed U.S. pharmacy. A vial should carry your name, what is in it and a beyond-use date.
Which ED injections are FDA-approved?
Caverject® and Edex® are FDA-approved injections for ED. Each contains alprostadil alone. They are different products from Trimix, which is a compounded mixture of three medicines. CHROMA23® does not offer them. Your doctor or a urologist can tell you whether one fits your situation.

Frequently asked questions
Is Trimix a scheduled drug?
No. Alprostadil, papaverine and phentolamine are prescription medicines, and none of them is on the federal controlled substance schedules.
Why would a provider prescribe something that is not FDA-approved?
The FDA says compounded drugs should only be used when an FDA-approved drug cannot meet a patient's needs. Ask your provider why a compounded medicine is being recommended, and whether an FDA-approved option fits you.
Is compounded Trimix the same as Caverject®?
No. Caverject® is an FDA-approved product containing alprostadil alone. Trimix is a compounded mixture of three medicines and is not FDA-approved.
