well I quess that answers my question re colonic. I have a pharmacist compound the drugs for me and either I or the doctor picks it up for me. The Pharmacist told us he cound not get the albendazole till mid september. This happened once before and I had a delay in my two week treatment schedule which then caused some lack of progress for me as I got sicker so the prazi is a stop gap measure as well as mixing up the drug protocal which is recommended apparently.I live in Canada.The cost of compounding is much more inexpensive then purchasing a premade pill. Albendezole in pill form is not even listed as a possible purchase at any of the pharmacies here. I was using a us pharmacy for it but then the cost increased over 300% no explanation besides repackaging.
