Viridal is currently on back-order for all strengths. New stock has finally started to arrive in small quantities as of July, but there will still be delays in shipping until the manufacturer gets back up to speed. If you order this, you can have Caverject sent instead if you wish to not wait. We also offer Vitaros and Muse if you are interested.

THIS IS THE CONTINUATION PACK. THIS DOES NOT CONTAIN THE APPLICATOR. FOR THE APPLICATOR, PURCHASE THE STARTER PACK.

Viridal Duo (alprostadil) is a vasodilator used in treating erectile dysfunction. Administered by injection, it temporarily relaxes muscles and widens blood vessels in the penis, increasing blood flow to the area. Ultimately it allows men to achieve and maintain an erection firm enough for intercourse. 

Viridal Duo is not a cure for any type of erectile dysfunction, but allows men to continue sexual activity while the underlying cause is found and addressed. The medication is effective in over 80 percent of men, regardless of the cause of the erectile dysfunction. 

Restoring Sexual Function with Viridal Duo 

Dosage should be determined by a doctor; in fact the first dose is usually administered in a doctor's office. This serves to both instruct on proper administration as well as find the lowest effective dose; higher doses put patients at greater risk of serious side effects. Subsequent injections are performed at home by the patient. 

Each Viridal Duo kit contains a number of syringes and sufficient medication to fill each syringe with one dose. The solution may need to be prepared at home; instructions will be included if this is the case. Once prepared, solution should be used immediately and any unused solution disposed of. 

Though initially intimidating, most men quickly become accustomed to administrating the medication: 

• Wash and dry hands and penis.
• Draw the prescribed dose of solution into a syringe.
• Clean injection site with an alcohol swab.
• Hold the penis against your thigh to keep it immobile.
• Fully insert the needle into the spongy tissue on the side of the penis.
• Do not insert the needle into visible veins.
• Press the syringe plunger until solution is gone.
• Remove needle and press an alcohol swab on the site for 5 minutes to prevent bleeding and bruising.
• Dispose of used needle; do not reuse.
• Choosing a different injection site and alternating sides of the penis with each use will reduce risk of bruising or scarring.
• Do not administer more than once in 24 hours.
• Do not administer more than 3 times in a week.
