What is Edex (alprostadil injectable and transurethral)?
Alprostadil is used to treat erectile dysfunction (impotence) and to help diagnose certain causes of this disorder. Alprostadil is also used to improve blood flow in newborn babies with a certain genetic heart condition. This alprostadil medication guide addresses only the adult male use of this medicine in erectile disorders.
Alprostadil relaxes blood vessels and muscles in the penis. This increases blood flow into the penis, causing an erection.
Alprostadil may also be used for purposes not listed in this medication guide.

How should I use Edex (alprostadil injectable and transurethral)?
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.
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
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.
Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.
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.
Alprostadil injectable is a powder medicine that comes with a sterile liquid for mixing it. Caverject Impulse is a brand of alprostadil injectable supplied as a needle and syringe that contains both the powder medicine and the sterile liquid. The dose is automatically mixed when you turn a dial on the end of the syringe. The Caverject Impulse syringe is designed for only one use. Carefully follow the instructions provided with this product.
Use a disposable needle and syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
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.
The Caverject Impulse device uses a very thin needle, which could break easily. If the needle breaks during injection and you can see and grasp the broken end, remove it and contact your doctor. If you cannot remove the broken end, call your doctor right away.
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.
Storing this medicine:
Keep each urethral pellet in its original foil pouch until you are ready to use it. Store the foil pouches in the refrigerator. You may store the pouches at room temperature for up to 14 days.
Store alprostadil injectable at room temperature. The 40 microgram strength of unmixed alprostadil can be stored at room temperature for up to 3 months, or until the expiration date on the label, whichever happens first.
Do not expose alprostadil products to freezing or very hot temperatures. Do not store your medication in a closed automobile, or pack it into luggage that will be placed into a cargo area during travel.
What happens if I miss a dose?
Since alprostadil is used as needed, you will not be on a dosing schedule.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
Overdose symptoms may include feeling light-headed, fainting, or having a painful or prolonged erection lasting 4 hours or longer.
What should I avoid while using Edex (alprostadil injectable and transurethral)?
This medication may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.
Taking this medicine will not prevent you from passing a disease such as hepatitis or HIV to other people. Do not have unprotected sex or share razors or toothbrushes. Talk with your doctor about safe ways to prevent HIV transmission during sex. Sharing drug or medicine needles is never safe, even for a healthy person.
