Always use this medicine exactly as your doctor has told you. Check with your doctor if you are not sure.
Before you use Viridal Duo at home, you must be taught how to prepare and inject it by your doctor. You should never start treatment without talking to your doctor first.
Remember: If you find it difficult to use your hands properly or if you cannot see very well your partner can be taught how to give you the injection.
Discuss this with your doctor if necessary.
For each injection you will need:
a) Easy-Duo® reusable. If you have used Viridal Duo before you should already have an injector.
b) One cartridge, which is made up of two chambers.
There will be 10, 20 or 40 micrograms of alprostadil (white powder) in the top chamber, and 1 ml of sterile saline (colourless liquid) in the bottom chamber
c) One injection needle with outer protective cap (1) and inner protective cap (2)
Notes:
- Please be sure to inspect the Easy-Duo® injector for visible damage before each use.
- The injector must only be used with viridal® cartridges and the supplied injection needles (BD Microfine + 0.33 x 12.7 mm).
- Injection needle (C) and cartridge (B) are not included in the Easy-Duo® case.
Check that the seal on the injection needle is not broken. Tear off the seal.
Put the needle on the end of the injector by screwing it clockwise until it is tight. Always screw on the injection needle before inserting the cartridge.
Unscrew the plunger from the injector. Take the cartridge and clean the tip with alcohol swab. Insert the cartridge into the transparent body of the injector. Take care to advance the bulge into the groove of the injector
Screw the plunger onto the back thread of the injector body.
Hold the injector with the needle pointing up. Push the plunger forward until the two grey stoppers of the cartridge meet. You will see that the liquid passes into the front chamber and the powder dissolves within a few seconds. Shake the injector gently until no bits can be seen. At first the solution may appear slightly cloudy because of the bubbles, but this will clear after a short time.
Remove the outer and inner protective caps of the needle. Warning: do not touch anything with the tip of the needle so that it stays clean and sterile (free from germs).
While you hold the injector with the needle pointing up, tap against the injector vigorously until all bubbles have moved upward. Cautiously advance the plunger until one drop of the solution leaves the needle. Make sure that all air was removed from the cartridge.
Set the dose your doctor prescribed you. To do so, move the plunger of the injector slowly upward until the upper edge of the front grey stopper has reached the prescribed dose.
Make sure that your penis has been cleaned thoroughly.
Clean the injection site with an alcohol swab. Draw the penis slightly away from your body until the intended injection site has dried.
Take the injector and make sure that the grey stopper is at the prescribed dose and that no air bubbles are in the cartridge.
The injection site must be within the area shown in figure 10.
Notes:
- Before the injection, specific training with the doctor or specialist is recommended.
- The administration of Viridal® can cause side effects, although not everybody gets them. Read the leaflet of Viridal® for their knowledge.
Hold the injector in your fingers as shown. Always hold it level with the penis and insert the needle almost completely straight, into the penis.
The place where you inject should be within the area shown on the picture. Use a different side of the penis than you used the last time.
Pushing your thumb gently on the plunger, inject the solution slowly over a period of 5 to 10 seconds.
After injection, remove the injector and needle from your penis and put it down. If bleeding occurs, apply pressure to the injection site with a clean pad for 3 minutes to stop the bleeding. If it continues to occur, carry on applying pressure until it stops.
It will take between 5–15 minutes for your erection to develop. Your erection should last for about one hour. If it lasts for between 2-4 hours, discuss this with your doctor. If it lasts for longer than 4 hours, contact your doctor immediately.
If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
