Tell your doctor you want a prescription for Sildenafil...
I don’t think my doctor would prescribe a drug upon my request unless she (my primary doc) deemed it necessary
This is no different. I would guarantee that she knows about this workaround.
Sildenafil is where Viagra came from. People taking it for its original use, blood pressure control, reported frequent erections. After further research and FDA approval, they started marketing as Viagra. Exactly the same, just a higher dosage.
I wasn’t doubting your interesting information that the two differently named drugs differed only in dosage. I suppose my doc would prescribe it if I mentioned that it was in place of Viagra which I assume she would prescribe.But being without a partner I don’t have a need.
