Other Brand Names:


Viridal 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 is used in adult males:

• to help you get and maintain an erection
• by your doctor to test whether you suffer from impotence.

Viridal 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.

Viridal is sold with or without an injector.  The plastic injector assembly resembles a syringe and may be re-used by inserting a fresh cartridge and new needle tip each time this medicine is required.

Please refer to the diagram of Viridal Duo:

For each injection you will need:
a) Easy-Duo® reusable injector. 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)

You may need to have regular follow up examinations by your doctor to check for the
formation of scar tissue on the penis.

You may take apixaban with or without food.

If you cannot swallow a tablet whole, crush and mix it with water, apple juice, or a spoonful of applesauce. Swallow the mixture right away without chewing. Do not save it for later use.

A crushed tablet mixture may also be given through a nasogastric (NG) feeding tube.

Do not stop taking apixaban unless your doctor tells you to. Stopping suddenly can increase your risk of blood clot or stroke.

• Other medicines to treat blood clotting as you may need special attention
