Viridal Duo contains the active substance alprostadil which belongs to a group of drugs used to treat erectile dysfunction. This medicine works by widening blood vessels and increasing blood flow to your penis.
Viridal Duo is used in adult males:
Viridal Duo comes in a glass cartridge with two chambers.
One chamber contains alprostadil, the other contains sodium chloride solution. These are mixed together to make a solution that is injected into the penis.
If any of the above applies to you talk to your doctor or pharmacist.
Talk to your doctor or pharmacist before using Viridal Duo
You may need to have further tests before your doctor can give you this treatment (for example, a stress resistance test and tests to check for other treatable underlying causes of impotence).
Erection lasting over four hours can be dangerous therefore you should report immediately to your doctor, or, if unavailable, seek immediate medical assistance for any erection that persists for longer than four hours.
Viridal Duo will not protect you or your partner from sexually transmitted diseases like chlamydia, gonorrhoea, herpes simplex virus, viral hepatitis, HIV, genital warts or syphilis.
As you may get a small amount of bleeding at the injection site, it is especially important that you use a condom to avoid sexually transmitted diseases.
Viridal Duo should not be used by patients with drug addiction, mental illness or intellectual disability.
You may need to have regular follow up examinations by your doctor to check for the formation of scar tissue on the penis.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
Tell your doctor if you are taking any of the following medicines:
You should wear a condom if your partner is, may be or could become pregnant. This is to avoid causing irritation of her vagina or possibly damaging the unborn baby.
If you have any questions on this or if your partner is breast-feeding, please ask your doctor or pharmacist for advice.
Viridal Duo does not interfere with ejaculation and fertility.
If you feel dizzy or faint after using Viridal Duo you should not drive or use machinery or tools.
Always use this medicine exactly as your doctor has told you. Check with your doctor if you are not sure.
Important:
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.
To test for impotence and to find out the dose of Viridal Duo you need:
For erectile dysfunction of primary neurological origin
For an erection:
Note on tearing open:
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:
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:
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.
After the first time you use this medicine and then again every 3 months or so, your doctor will ask you to have check-ups. These are to make sure that your medicine is working properly and that the dose you are taking is right for you.
Immediately contact the nearest hospital casualty department or your doctor. Using too much Viridal Duo can increase your risk of scarring to the penis and can cause your erection to last too long which may require treatment by a specialist doctor to reverse the effects.
If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
