Important information about Caverject Impulse

How does Caverject Impulse work?

The active ingredient in Caverject Impulse is alprostadil. It is a synthetic prostaglandin E1 (PGE1) agonist which works locally to dilate the blood vessels of the penis, relaxing the muscles to stimulate an erection. It is classified as a vasodilator in the PDE5 inhibitor class of medications.

How do you use Caverject Impulse?

Follow all directions given to you by your doctor and read all documents provided, including the full Prescribing Information, FDA-Approved Product Labeling, Instructions for Use, and Medication Guide, before using Caverject Impulse. However, the following is a synopsis of the general guidelines for the use of Caverject Impulse:

1. Ensure you get training from your doctor on the self-injection technique to safely administer this medication.

2. Always wash your hands before and after injecting this medication.

3. Open the plastic tray, and you should see: a syringe, a needle assembly, and alcohol swabs. Inspect the needle; in the case of a bent needle, do not use it.

4. Using an alcohol swab, wipe the rubber covering at the tip of the syringe.

5. Then pick up the needle assembly and peel back the paper cover.

6. Holding the needle assembly by its cap, press it upon the tip of the syringe, turning clockwise until locked in place.

7. The syringe system should be held with the needle pointing up, and then the plunger rod should be turned clockwise until it stops.

8. Next, turn the syringe upside down many times until the solution turns clear. Do not use the product if the solution is not clear.

9. Then, hold the syringe with the needle pointed upwards and take off the inner protective cap. Lightly tap the glass cartridge to move any large bubbles to the top, then push the plunger rod until it stops to remove the bubbles.

10. Next, to set your dose, find your dose window and slowly turn the plunger rod clockwise until the correct number is in the window. If you go past the number, just keep turning clockwise until it is visible again (do not turn the plunger rod backwards).

11. For administration, wipe the injection site - left or right side of the penis, not on top or bottom with an alcohol swab and let air dry.

12. When injecting, be sure to avoid any visible veins and alternate sides and sites for injection. Take hold of the penis from the tip, and squeeze gently, ensure to streth the foreskin if present.

13. Remove the cap and insert the needle at a 90 degree angle on the side of the penis into the corpora cavernosa (bulgy part). Once inserted, push the plunger to inject the medication until it stops. Hold for a few seconds, then pull the needle out and dispose in a sharps container.

14. Using an alcohol swab or gauze, compress the site of injection for 5 minutes.

Each syringe is single-use only - do not reuse them. Do not use Caverject Impulse more than three times per week or more than once in a 24-hour period.

What are the side effects of Caverject Impulse?

The most common side effects of Caverject Impulse seen in clinical trials include:
