Caverject: What It Is, How It Works, and Alternatives You Should Know

When Caverject, a brand-name injectable medication containing alprostadil used to treat erectile dysfunction by increasing blood flow to the penis. Also known as alprostadil injection, it’s one of the few ED treatments that works even when pills like Viagra or Cialis don’t. Caverject isn’t a daily pill—it’s a quick, targeted shot that triggers an erection within minutes. It’s often used by men who can’t take oral ED drugs due to heart conditions, diabetes, or side effects from other medications. Unlike pills that rely on sexual stimulation to work, Caverject physically opens blood vessels in the penis, making it possible to get and keep an erection regardless of arousal levels.

Alprostadil, the active ingredient in Caverject, is also found in other forms like urethral suppositories (MUSE) and topical gels, but injections deliver the fastest, most reliable results. This treatment requires training—you learn how to inject it safely into the side of the penis, avoiding veins and tendons. Most men report mild discomfort, not pain, and side effects like bruising or prolonged erections are rare if used correctly. It’s not for everyone: men with penile implants, severe curvature, or blood disorders should avoid it. But for those who’ve tried everything else, Caverject can be a game-changer.

Related options like penile injection therapy, a category of ED treatments involving direct injection of vasoactive drugs into the penis to induce erection include generic alprostadil and combination drugs like Bimix or Trimix, which mix alprostadil with other agents for stronger effects. If injections feel too invasive, alternatives like oral medications (tadalafil, sildenafil), vacuum pumps, or even low-intensity shockwave therapy might be worth exploring. But if you’re looking for something that works fast, works consistently, and doesn’t need to be taken hours before sex, Caverject still holds its ground.

What you’ll find in the posts below are real comparisons, patient experiences, and practical tips—not just drug facts. You’ll see how Caverject stacks up against other ED treatments, what to expect on your first injection, how to reduce side effects, and even how some men combine it with other therapies for better results. There’s no fluff, no marketing buzz—just straight talk from people who’ve been there.
