Are you Looking to Buy Caverject Kit (Alprostadil) from Pharmapassport.


Generic Name: alprostadil 

Drug Class: prostaglandin E1 agonist


Caverject is an intracavernosal prescription injection used to treat erectile dysfunction (ED), also known as impotence. This is also prescribed as an adjunct to other diagnostic procedures or tests in diagnosing erectile dysfunction. 

Dosage Forms 

This is available in Caverject 20 mcg lyophilized powder in a single-dose vial.

Caverject Mechanism of Action 

This injection has a vasodilating effect while inhibiting platelet aggregation. It can induce an erection by relaxing the trabecular smooth muscle and dilating the cavernosal arteries through binding into the receptors and increasing the levels of cyclic adenosine monophosphate. 

How to Inject Caverject 

Before using this injection, it is necessary to read the drug information or patient information leaflet, or medication guide given by a healthcare professional. You must not use any medication unless you have understood the uses and directions. Ask your doctor or pharmacist for further medical advice or additional details. 

This intracavernosal injection is prescribed as needed. This is administered before sexual activity. Do not increase/decrease your Caverject dosage and always use this product precisely as advised. You must not use it more than three times a week, and there should be at least 1-day interval. 

Step-by-step Guide on how to use Caverject: 

  1. Using an alcohol swab, wipe the injection site and let it dry.
  2. If uncircumcised, pull the foreskin back. Then, hold the tip of your penis using your thumb and forefinger. Stretch it lengthwise down your thigh.
  3. Squeeze your penis using the thumb and another finger until the injection site bulges. Position the penis against your thigh to keep it from moving.
  4. Remove the needle cap of the injection and push the needle into the proximal third of your penis. Remember not to inject it into veins or blood vessels.
  5. In a slow and steady manner, push the plunger carefully to eject medication.
  6. Pull the needle slowly out of the injection site and press the site gently for about 5 minutes using a clean cotton swab.
  7. Dispose the used needle and syringe accordingly.
