Edex

Alprostadil injection shouldn't be used more than 3 times per week and shouldn't be given more often than 1 time every 24 hours.

You should receive training from your provider on how to give yourself alprostadil injection. Make sure you know how to give yourself alprostadil injection to avoid accidentally hurting yourself or wasting the medication. Contact your provider if you have any questions on how to use this medication.

Store Edex, Caverject Impulse, Caverject 20 mcg vials at room temperature before mixing. If you have Caverject 40 mcg vials, store them in the refrigerator before mixing.

If you're using Caverject, after the medication is mixed, store it at or below 77ºF (but don't refrigerate or freeze the medication) and use the dose within 24 hours. If you're using Caverject Impulse, after the medication is mixed, store it between 36ºF to 77ºF (but don't freeze the medication) and use the dose within 24 hours. If you're using Edex, use the dose right away after mixing it, don't store it for future use.

Wipe the site of injection with an alcohol wipe before injection in order to clean the area. After injecting, hold a sterile gauze or alcohol wipe to the injection site for 5 minutes to prevent or stop bleeding.

Only inject alprostadil injection into the side or base, on the lower one-third of your penis. Make sure to alternate injection sites and the sides of your penis that's injected to avoid skin irritation and pain. Don't inject into visible veins. Doing so can cause the medication to get into your blood stream, which can cause serious heart side effects.

After giving yourself the medication, throw the needle and syringe away in a sharps container or something made of heavy-duty plastic, such as an empty milk carton or laundry detergent bottle, to lower the risk of needle-stick injuries. Don't throw away needles or syringes in your trash can. When your sharps container is almost full, close it tightly with the cap. For more information on how to throw away your sharps container safely and guidance for your specific state, visit the FDA's website.

Each alprostadil injection vial (Caverject), syringe (Caverject Impulse), and cartridge (Edex) should only be used once. Throw them away after you administer the injection. Don't save any leftover medication to avoid infections.

Always check the medication solution to make sure it's clear and colorless before using it. If it's cloudy, discolored, or has particles (solid chunks), don't use it.

If the needle is bent, throw it away into a sharps container and attach a new, unused needle. Don't try to straighten it because you might poke yourself. Don't re-use or share needles to avoid spreading infections.

Get medical help right away if you have an erection that lasts longer than 4 hours so you can receive treatment to prevent permanent damage to your penis.

Using alprostadil injection doesn't protect you from sexually transmitted infections (STIs) and doesn't prevent pregnancy.

You should see your provider every 3 months for check-ups to make sure it's safe for you to continue taking alprostadil injection and to examine your penis for side effects, such as scarring, skin irritation, and changes in skin color.
