Penile injections are an option to help you get an erection if medications and other methods don’t work for you. These prescription injections are safe, easy to administer yourself (after a quick lesson) and will provide an erection lasting at least half an hour. You’ll probably feel a bit of a sting at first (just like a flu shot) but most people don’t find the injection painful. Between five and 15 minutes after the injection, you should have an erection. An actual penile injection is shown in the video below.

Are there side effects?
A rare side effect, known as priapism, is a full erection lasting more than two hours. This is caused by administering too large a dose which is why it’s a good idea to do a test dose at a clinic before using this medication at home. Your dispensing clinic should supply an antidote if an overdose occurs. Pseudoephedrine used in ‘Sudafed’ can also help reduce a priapism. A very small number of men may develop some changes in their penis when using injections for a long time so it is important to check your penis on a regular basis. If you notice any changes, then please see your medical specialist.
Does it interfere with any other medications?
The injections are safe with any medication you are currently on. If in doubt, always discuss this with your medical specialist. Your doctor or specialist can also assess your overall health and offer guidance on whether these injections are suitable for you.
