Intracavernosal Injections for ED

Intracavernosal injection therapy delivers a small dose of vasodilating medication directly into the side of the penis, where it relaxes blood-vessel and smooth muscle to produce an erection. Because it acts locally on blood flow, it can work even when oral ED pills do not. Revibe’s providers train you to self-administer safely at home.

Oral PDE5 inhibitors (like sildenafil and tadalafil) enhance the body’s own arousal-driven signals and depend on intact nerve and blood-flow pathways. ICI works more directly on penile blood vessels and does not rely on those same signals, which is why it is often effective for men with nerve-related, vascular, diabetes-related, or post-prostate-surgery ED that doesn’t respond to pills.

ICI is fast-acting: an erection typically develops within about 5 to 15 minutes of the injection. Unlike oral medications, it does not necessarily require sexual stimulation to produce an erection, which is one reason dosing must be carefully individualized.

Most men find the injections more comfortable than expected because a very fine needle is used and the sides of the penis are relatively less sensitive to needle sticks. Revibe’s providers teach proper technique to minimize discomfort and reduce risk.

ICI may use alprostadil alone or a compounded combination of medications (commonly referred to as bimix or trimix, which can include papaverine, phentolamine, and alprostadil). The specific formulation and dose are chosen and adjusted by your provider based on your response.

Correct injection site, technique, and dose are essential for both effectiveness and safety, so Revibe’s providers train you before you self-administer and start with a carefully titrated dose. Ongoing check-ins let your provider fine-tune the plan.

Yes, ICI is a well-established, effective option for men who don’t respond to or can’t take oral ED medication, including many complex cases. A Revibe provider will evaluate whether it fits your medical history and goals.

Possible side effects include penile pain or aching, minor bruising at the injection site, and—most importantly—a prolonged erection (priapism). With long-term use, some men develop scar tissue (fibrosis) at injection sites. Careful dosing and provider monitoring reduce these risks.

An erection lasting more than four hours is a medical emergency and requires prompt treatment to avoid permanent damage. Because ICI is potent, your provider will give you clear instructions on recognizing and responding to a prolonged erection before you begin at-home use.
