If you’re tried oral treatments for ED and these haven’t worked, or if you can’t take Viagra or Cialis because you’ve got a medical condition or are taking something that could interfere with them, a clinician will normally suggest an alternative.
Viridal Duo is a treatment that’s more often used when other medications have failed. It’s an injection so is a little more invasive than a tablet, but it can help men who’ve had no success with tablets.
