Weirdly, they administered sildanefil vaginally. You’ll need a pharmacist and a laboritory to create sildenafil vaginal suppositories, so a bit above grad school level.

Still something that any pharmacy can do for a low price. They only need to grind up regular sildanefil pills and put the powder into vaginal suppositories.

Our pharmacy did something similar for anal suppositories for our baby when there were covid-related shortages for ibuprofen suppositories.
