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.

Effectiveness

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

Off-Label Uses

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.

Prostate Cancer

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.
