Viridal Duo is a medication for adult males designed to help you get and maintain an erection. The medication is supplied intravenously via injection. The active ingredient in Viridal Duo is alprostadil, which is s type of medicine known as a prostaglandin.

How does Viridal Duo work?

Alprostadil acts in the same way as a naturally occurring chemical called prostaglandin E1, which is believed to widen some blood vessels by relaxing the thin layer of muscle in the vessel wall. Alprostadil, therefore, improves the blood flow to the penis, whilst causing blood to remain there, thus facilitating the complex chain of reaction that leads to an erection.

How to use Viridal Duo erection medication

Viridal Duo injections are injected directly into the penis. Your doctor will talk to you about the correct way to do this. It is very important to exactly follow the instructions given by your doctor those supplied with the Viridal Duo.

What is the correct dosage for Viridal Duo erection medication?

The dosage determines the length of time of the erection, which can vary between 2 and 15 minutes. This medication is available in three pack sizes:

  • Viridal Duo 10 mcg;
  • Viridal Duo 20 mcg;
  • Viridal Duo 40 mcg.

Your doctor or pharmacist will calculate the right dosage for you before you obtain the Viridal Duo starter pack or the Viridal Duo continuation pack.

Warning – this medicine should not be used more than once a day or more than three times over a week.

If your erection lasts for more than four hours, you should seek medical advice as this is known as priapism. If medical treatment is not received within six hours, lasting damage can occur to the erectile tissues of the penis.

This medicine is solely for the use of achieving and maintaining an erection. It does not provide any protection against STDs or pregnancy.
