When Pills Fail: Injection Therapy And Vacuum Erection Devices To Achieve Erections
The discovery of PDE-5 inhibitors such as Viagra and Cialis was a truly revolutionary step forward in the treatment of erectile dysfunction, and nearly every man, and most women, are aware of its common usage. That usage is so widespread because of the simple fact that impotence, or erectile dysfunction, is largely a matter of aging and in large part is inevitable to some degree in all men eventually. Commercials project an image of a wonder-pill that restores a robust sex life. What is not part of the marketing for pills is that they are effective roughly 70% of the time, and in reality, only work well for patients with only partial impotence. This means that patients that suffer more severe organic impotence caused by medical problems such as diabetes and cardiovascular disease, as well as patients with erectile dysfunction as a result of surgery such as prostatectomy, are the least helped by PDE-5 inhibitors. These patients are best served by either injection therapy or vacuum erection devices.
Injection therapy is the act of a man injecting medicine into his own penis to achieve an erection when he desires one. Injections almost always work and are widely used although most men are not aware they exist as they are not marketed on television. However, a closer look will reveal how mainstream they are. If one sees an ad for an erection clinic in the newspaper or on the radio, these are clinics that basically just offer shots at a very high price under the premise that they are offering something not readily available. However, all Urologists help their patients with injection therapy at a cost far less to the patient.
A vacuum erection device is a tube which is placed over the penis and pulls venous blood into the penis. A constricting band is placed at the base of the penis to hold the blood in as a tourniquet would. Such devices are readily available and economical and are a perfect solution for some. However, patients can struggle with the device fitting properly, the suction can cause pain, and the female partner may complain that the erection feels relatively cold. Also, vacuum erection devices are not very useful in the first six months after prostatectomy. For all these reasons, Dr. Engel favors injection therapy for all those with severe impotence. Vacuum erection devices are reserved for those that are needle-phobic or do not have the dexterity to inject themselves. In these cases patients are advised to purchase a vacuum erection device on Amazon or a similar place, and to be sure to buy one that uses constricting bands, is medical grade, comes with instructions and support and seems professional in nature.
Medicines Used In Injection Therapy
The first medicine used for this purpose was Papaverine, a potent vasodilator (makes arteries dilate). Papaverine unfortunately can cause priapism, or a dangerous and painful erection that will not go down, with some regularity. Thus, other medicines are also used today for this purpose, often as a mixture of medicines to be able to utilize the benefits of each drug and limit its side effects.
The most common medicine used today is Prostaglandin, with the main side effect being pain. Another is phentolamine. When all three are mixed, it is called Tri-Mix. Others can be added such as Atropine to produce Quad-Mix. The proportions of these medicines can be changed to lessen one side effect or another until a useful solution is found.
Injection therapy should be taught to the patient, and Drs. Engel and Losee instruct their patients personally in the office. The medicine would have been prescribed from a specific compounding pharmacy during a previous visit, and that medicine with alcohol swabs and syringes would have been shipped already to the patient at his home. During the teaching visit, the patient brings their medicine to the office with their own needles and alcohol. The needle and syringe that is used is identical to what a diabetic would use to inject insulin. At that visit, the patient is taught how to draw up the medicine, how to use the syringe and needle and communicate about their dose using the numbers on the syringe only without units. The patient is also instructed how to hold the penis properly to allow for the easiest administration, and lastly how to inject. Results are immediate with injections, and they generally work more reliably and more completely than any other modality. But, they require motivation. All patients are apprehensive about giving themselves a shot, but the almost unanimous reaction of the patient is that it is far easier to do than they imagined, and the patient gets very used to it over time just as a diabetic does. What helps is to come prepared to this visit, having studied the written hand out given to them at a previous visit, perhaps watching YouTube videos, and to have read extensively a description of the injection procedure on a website such as this one. Below are detailed instructions, a diagram and a photo that should prepare patients greatly for their teaching visit in the office.
The medicine will come in a small vial that is to be kept frozen when not in use. The foil is removed, the top is wiped with alcohol, and the needle is inserted into the bottle. It is best to pull the plunger of the syringe back to what is the intended dose number, and then to insert the needle into the bottle. That amount of air is injected into the vial, and with the vial upside down the medicine is drawn back into the syringe. Usually one pulls more than is needed into the syringe, and then depresses the plunger with the needle still in the vial until the desired number or dose is reached. The needle is then withdrawn, and the needle and syringe are set aside. The patient is now ready to inject himself.
Proper Way to Hold the Syringe

Although patients usually see the actual injection as the key here to success and certainly the focal point of their anxiety, the most important things for the patient to master is how to hold their penis properly and where to inject. Often the patient will hold their penis at first only to then focus only on their injection hand and then fail to continue holding their penis in an advantageous way. The more firmly the penis is pulled away from the body, the easier the needle will be inserted into the penis. So, maintain focus on the non-dominant holding hand perhaps even more so during the injection. The figure below illustrates these concepts clearly. The penis is held with the non-dominant hand with the index and middle finger under the urethral meatus, and the pad of the thumb over the top of the glans or head. It is vital to hold the head of the penis without touching the penile skin at all, then to pull the penis straight out from the body as firmly as possible. This allows the needle to slide in with ease. Then, with the dominant hand, the patient holds the syringe like a cigarette between the index and third finger, with the thumb holding the syringe at the level spot below the plunger. (See photo) Then, the injection is to be done anywhere along the shaft at what would be 10 or 2 o’clock when viewing the penis straight on from the head. The shot must be perpendicular to 10 or 2 o’clock as shown in the drawing, and the needle must not slip down towards the urethra. The patient touches the skin with the needle, engages the skin and then pushes the needle all the way in. Only the skin senses pain here, so the depth of the needle does not dictate the pain at all. Then, the medicine is injected, after which the needle is removed quickly, and pressure is applied with the alcohol swab for perhaps 10 seconds to avoid bruising. Patients will be asked to attempt to get an erection, and the results are then evaluated. The response in the office will dictate what the starting dose at home should be.
Proper Method to Hold the Penis

A very low dose will be used in the office based on existing erectile function and then Dr. Engel or Dr. Losee will advise a starting dose at home. The dose should be increased by small increments after the starting dose, often as low as 2 on the syringe but more typically 4 or 5. Finding the right dose in this incremental way should avoid priapism and therefore is mandatory. Of course, this means that often the first several attempts will not result in intercourse. Patients should expect that. However, the dose should simply be increased each time until a dose that produces a firm erection adequate for satisfactory intercourse while not lasting over an hour is achieved. Patients should not think that they should stop increasing the dose at any point if a good erection does not occur. Occasionally, patients will need a high dose such as 80 or more. In these cases, the prescription can be adjusted to a higher strength solution at the next office visit.
Risks and Consideration of Injection Therapy
Injections are very safe, as a negligible amount of medicine actually enters the patient’s bloodstream. The main thing to avoid is priapism, which happens very rarely if starting with a low dose as instructed by us. If an erection is lasting beyond three hours, Sudafed should be taken immediately, and ice should be applied to the penis. This really should be done on the way to an emergency room with the hope that the penis will get soft on the way in. An erection lasting four hours will usually be quite painful and requires an immediate visit to an emergency room – preferably George Washington or Sibley so that we may manage your care. Patients are told to alternate the sides of injection if possible or to avoid injecting in the same spot on either side repeatedly in an effort to reduce the risk of scarring which may occur. Patients are to perform an injection at most every other day, and very importantly to never give a “booster” injection if a good erection is not achieved with one injection which is one of the most common reasons for priapism.
In short, injection therapy should be the next step if pills fail. They are not rare, not “weird”, and are certainly used with far more regularity than the public is aware. They are a great solution, and all patients are strongly encouraged to try them before giving up on an active sex life. We will be more than happy to help you.
