Dr John Campbell has had a guest recently praising fen ben, another anti parasitic. I would look for a Dr willing to inject IV Calcifediol the active form immediately available. Oral tabs take far too long.
Calcifediol, also known as calcidiol, 25-hydroxycholecalciferol, or 25-hydroxyvitamin D₃, is a form of vitamin D produced in the liver by hydroxylation of vitamin D₃ by the enzyme vitamin D 25-hydroxylase.
