Injection site
You should sit up straight or lie back slightly when you inject CAVERJECT.
CAVERJECT is injected into the spongy tissue of the penis. It runs up and down your penis on the right and left sides.
- Choose an injection site on one side of the shaft of the penis
- Make sure you avoid any veins you can see
- Change the side of the penis you inject each time
- Change the spot you inject each time
- Hold the head of your penis with your thumb and first finger
- Stretch your penis lengthwise along your thigh so the skin is tight
- Clean the injection site with a new alcohol swab
- Do not throw this swab away. You will use it again
Hold the penis firmly against your thigh to keep it from moving during the injection. Hold the device between your thumb and first finger.
- Push the needle into the injection site until the metal part of the needle is almost all the way in the penis
- Push the plunger rod in as far as it will go—until all the medicine is injected
Grasp the syringe barrel to pull the needle out of your penis.
IMPORTANT: After you pull the needle out of your penis, hold the alcohol swab on the injection site for about 5 minutes, or until any bleeding stops.
- Carefully put the outer cap back on the needle
- Never share your medicine with anyone
Disposal
The CAVERJECT needle and syringe should never be reused.
- After injecting, throw out the used syringe right away. Put it in a special container made for used syringes and needles. It can be a hard plastic container with a screw-on cap. Or a metal container with a plastic lid labeled "Used Syringes." Do not use glass or clear plastic containers
- Learn the right way to throw out used vials, needles, and syringes. Be sure to ask your doctor or pharmacist what to do
- You can get these special containers from your doctor or pharmacist. Do not throw the container in the household trash or recycle bin. Always keep this container out of the reach of children
