decision pointShould I use injections for erection problems?

An erection problem is not a life-threatening condition, yet it can seriously affect your emotional health and sense of self-worth. It can also make it difficult to father a child, if that is your desire. So the decision about whether to treat an erection problem is often based on your and your partner's preferences. Consider the following when making your decision:

  • If you are able to try phosphodiesterase-5 inhibitors (such as sildenafil [Viagra], tadalafil [Cialis], and vardenafil [Levitra]) but have not, you should try one of these medicines first.
  • At this time, it is not known how effective injections are in those who have already tried phosphodiesterase-5 inhibitors.

What is an erection problem?

An erection problem (also called erectile dysfunction and sometimes impotence) refers to a man's consistent inability to get or maintain an erection sufficient to have satisfactory sex. It does not mean a lack of sexual interest or desire or the occasional difficulty achieving or maintaining an erection that affects all men at some time in their lives.

What causes an erection problem?

The cause of erection problems may be physical (such as injury to the nerves or loss of blood flow going to the penis) or psychological (such as anxiety or depression). Medications you take for other conditions, alcohol consumption, smoking, and illegal drug use can cause erection problems.

Certain conditions may affect blood flow or the nervous system, increasing the risk of having erection problems. These include diabetes, high blood pressure, high cholesterol levels, atherosclerosis, multiple sclerosis, and Parkinson's disease.

Erection problems can occur at any age but are more common in older men, who often have additional health problems or who may be taking medicines that can interfere with normal erectile function. Treatment of erection problems in older men can be as effective as in younger men.

Why treat an erection problem?

The decision about whether to treat an erection problem may not be as straightforward as the decision about whether to treat many other medical conditions. An erection problem is not life-threatening, yet it can seriously affect your emotional health and sense of self-worth. It can also make it difficult to father a child, if that is your desire. So the decision about whether to treat an erection problem is often based on personal preference.

Very often, this decision is also based on how intensive or invasive the treatment is and its chance of succeeding. Injecting medication directly into the penis is often effective, but it is usually only considered after oral medicines (such as sildenafil [Viagra], tadalafil [Cialis], and vardenafil [Levitra]) have been tried.

Your choices are:

  • Try MUSE (medicated urethral system for erections), which calls for inserting a tiny pellet of alprostadil into the opening at the end of the penis (the urethra). A thin tube contains the pellet of medicine. The tube is inserted into the opening in the end of the penis. By pressing a button on the applicator, the pellet is released into the penis.
  • Inject medication into the side of the penis. This often involves using a mixture of medicines that include alprostadil (Caverject), papaverine hydrochloride (Pavabid), and phentolamine mesylate (Regitine).
  • Try counseling or sex therapy.
  • Seek other ways to express intimacy.

The decision about whether to use injections or pellets takes into account your personal feelings and the medical facts.

MUSE

  • About 6 out of 10 men using MUSE achieve erections sufficient for intercourse. But smaller doses have smaller percentages of positive results.1
  • Erection develops in about 10 minutes and lasts 30 minutes to an hour or longer.
  • MUSE does not usually cause bruising or scar tissue (as injections may).
  • The medicine causes severe pain.
  • The tube used to insert the medicine causes mild injury to the urethra, such as a scrape that causes a small drop of blood at the tip of the urethra.
  • The medicine can cause pain and irritation in your partner's vagina when you ejaculate.
  • Your partner cannot perform oral sex while you are using this medicine.

Injections into the side of the penis

  • Up to 90% of men using this method achieve erections sufficient for sexual intercourse.2
  • Erection lasts 30 minutes to an hour or longer.
  • Dose can be adjusted to create an erection that lasts the desired length of time
  • Auto-injector is available if unable to give standard injections.
  • Injections can bruise the penis.
  • Injections can cause mild to moderate pain in the penis.
  • Repeated injections can lead to scar tissue in the penis (fibrosis).
