What is the dose of alprostadil for an adult?

Your first dose of this medicine will be given in your doctor’s office so you can be watched for how well the medicine works and if it causes any side effects. You will then be shown how to properly give the medication to yourself. Wait at least 1 day after your first dose before using the medicine again.

Alprostadil is used only when needed to get an erection. An erection should occur within 5 to 20 minutes after you use the medication, and should last for 30 to 60 minutes. The length of time your erection lasts may be slightly different.

The injectable form of alprostadil is injected into the side of the penis.

The transurethral pellet is a very small suppository that is inserted into the opening of the penis (the urethra).

Do not use more than 2 alprostadil pellets in one day (24 hours). Do not use more than 3 alprostadil injections per week. Allow at least 24 hours to pass between injections.

Prepare your alprostadil dose only when you are ready to use the medicine. Do not shake the mixed medicine. After mixing, the medicine should be clear. Do not use the medicine if it looks cloudy or has particles in it. Call your pharmacist for new medicine.

Do not give yourself an alprostadil injection or pellet if you do not understand the instructions for proper use. Call your doctor or pharmacist for help with injection instructions. Using an alprostadil transurethral pellet improperly could cause damage to your urethra.

An alprostadil injection can cause bleeding where the needle is placed. This can make it easier for your sexual partner to be exposed to your blood. A virus such as hepatitis or HIV can be passed to another person who comes into contact with your blood.

To be sure alprostadil is not causing harmful effects, your penis may need to be examined every 3 months. Visit your doctor regularly.
