What about penile injections?

Why can I not simply pop a Viagra, Cialis or Levitra?

No matter how successful they are for most men regardless of age and regardless of the underlying cause of erectile dysfunction (ED), there are limits to the PDE-5 inhibitors. These limits may be physical - the underlying cause of the ED is sufficiently far advanced that Viagra, Cialis or Levitra simply will not work. Or you may already be taking medications for those underlying causes which, for now, make it impossible for you to take one of the PDE-5 inhibitors at an effective dosage.

So if either you or your partner are prepared to learn how to give the injections, this is a good system, available to use whenever you want with no real preparations required. Once given, they produce erections that are close to the body’s own spontaneous erections and allow you to have an orgasm and an ejaculation. Injection prolong erection for minimum 30 minutes. This is a cost-effective alternative to the more expensive and invasive surgical option. The only drawback is that the use of the injections is usually limited to three or four times per week to reduce the risk of scarring to your penis.

It is also available as a small pellet sold under the brand name, Muse, which you insert into the tube through which urine passes from the bladder out of your body. Now this is slightly more complicated than it sounds. You have to use a device which opens up the canal sufficiently to allow the tablet to be inserted inside your penis. This may not be a completely comfortable process either in the insertion or when the penis closes around the pellet. As you will realise, the tablet slowly dissolves and so the pressure on the penis diminishes fairly rapidly. Some men report a slight burning sensation as the medication is absorbed into the penis. There can also be a drop in your blood pressure so you should not be taking any other medication which may have an additive effect. It is also not advisable to consume alcohol before using Muse.

Papaverine is a vasodilator used to relax blood vessels and it was adapted for this purpose almost twenty years ago. It rarely causes any pain although it has a slightly higher risk of causing priapism (an unnaturally long and painful erection which should be treated as an emergency to avoid damage to the penis) because it remains active in the body for a longer period of time than Alprostadil. It may also be slightly more likely to cause scarring if you hit the same injection point too often. Heavy smokers should also take care. You also cannot mix this medication with:

  • treatments used for inducing sleep or treating seizures;
  • medicines such as temazepam or diazepam for sleeping or anxiety problems;
  • medicines to control Parkinson’s disease;
  • some narcotic pain killers similar to morphine.

The third drug is also a vasodilator: phentolamine sold as Regitine or Rogitine. It is rarely used on its own but usually in combination with one of the other two medications mentioned above.
