Maybe an albendazole iv? which someone mentioned they saw on the show Monsters Inside Me. Of course, one would need to get hooked on to this by your physician.
Meds don't seem to be working for a lot of us lately. I'm much better than I was off the protocols but I have die hards, one in thigh and head that just won't die.
Can you see your physician? If you're in as bad shape as you described your immune system seems really out of whack. I felt like this after several rounds of valbazen, I took Onwards basic dewormer recipe ( search on forum for) and it really pumped my immune system back into shape, can't say it cured my worms but if you're feeling crappy and losing weight I highly recommend it. Other than that, I can't help you with any stronger meds that you could try, i wish I knew the answer to that myself.
Hopefully someone will come along that knows more.
