HOW TO USE THIS MEDICINE: Follow the directions for using this medication provided by your doctor or pharmacist. Ask your doctor, nurse or pharmacist any questions that you may have about this medicine. The medication is injected directly into the penis when an erection is desired. Full resopnse to the drug should be obtained in five to ten minutes, and should last thirty minutes to one hour.

Unless directed otherwise, use the following procedure for injection preparation and administration:

Supplies needed:

1/2” 29 gauge insulin syringes vial of medication
alcohol swabs sharps container for needle disposal


1. Wash your hands thoroughly and dry them with a clean towel.
2. Handle the syringe by the syringe barrel only. Do not touch the needle or allow the needle to touch any surface.
3. Wipe the rubber stopper on the vial with an alcohol swab. Discard the alcohol swab.
4. Grasp the syringe barrel and pull the plunger to the volume mark on the syringe.
5. Remove the plastic needle cover. Push the needle through the vial’s rubber stopper and push
the plunger all the way down to expel the air into the vial.
6. Without removing the needle turn the vial upside down. Hold the syringe with the needle pointing up, keeping the needle tip below the level of fluid and slowly pull back on the syringe plunger until just past the volume mark.
7. If there are air bubbles, gently tap the syringe barrel until they float to the top of the solution.
Holding the syringe upright, push the syringe plunger to the volume mark. This will expel any air and excess solution into the vial.
8. Grasp the syringe barrel (not the plunger) and pull the syringe from the vial. Place the needle cover over the needle and set the syringe aside.

Store the medicatioin in the refrigerator. Do not use this medication past the expiration date or if there is a color change or particles in the solution.

1. You should be sitting upright or slightly reclined when performing the injection.
2. Choose an injection site on the side of the shaft of the penis, in the first one-half area closest to the base of the penis. Avoid visible blood vessels.
3. Holding the head of your penis, stretch it lengthwise along your thigh so that you can clearly see the selected injection site. Clean the injection site with a new alcohol swab.
4. Remove the cover from the needle. Position the penis firmly against your thigh to keep it from moving during the injection.
5. Hold the syringe between your thumb and index finger. Using a steady motion, push the needle straight into the selected site until the metal part of the needle is almost entirely in the penis.
6. With a steady motion, push down on the plunger so that the entire volume of solution is slowly injected. Grasping the syringe barrel, pull the needle out of your penis. Apply pressure to the injection site with the alcohol swab for about 5 minutes.
7. Place the used syringe in a sharps container for disposal. Do not reuse the syringe.
- Alternate the side of the penis and vary the site of injection with each use.
- If an erection lasts longer than 4 hours, you must immediately call you physician.
