What to know about PGE-1
How it Works
PGE-1, also referred to as Alprostadil, injection therapy consists of injecting a vasodilator medication directly into the shaft of the penis with a very fine needle. In the case of PGE-1, this injection is usually one of three medications, alprostadil being the most common to inject on its own.
Who’s it For?
PGE-1 injections are best for cases where the oral medications cause intolerable side effects, or if oral medications do not work.
PGE-1 is one of the three drugs often used for Injection Therapy. Injections are one of the most effective forms of ED treatment: up to 92% of patients find it effective. According to most studies, Prostaglandin E1 (PGE-1) has been found to have an effectiveness rate of approximately 91%.1

A common practice, off-label prescribing is when a doctor prescribes a drug for a different condition or at a different dosage than the FDA has approved. For PGE-1, there are a few conditions prescribed off-label. Always consult your physician before beginning a new treatment or modifying your existing treatment.
FDA Approved Use
PGE-1 is often recommended for men suffering from more advanced erectile dysfunction or who have other comorbidities impacting their ED.
PGE-1 may be prescribed for men who have just had a radical prostatectomy for prostate cancer. Injection Therapy is commonly used to aid in the recovery process.
PGE-1 Side Effects
- Scarring at injection site (if injections aren’t rotated)
- Slight pain at the injection site
- Priapism (Erection lasting more than 4 hours)
- Aching sensation in penis
Good to Know
Use of PGE-1 should not exceed 3-4 uses within a single week and no more than once in a 24 hour period unless directed to do so by your physician.
Punctured or sealed vials must be refrigerated. Trimix multi-use vials are safe to use up to 28-days after first puncture. Do not freeze.
