I've used Albendazole. I have recently figured out that I have a large population of flukes. So the problem is that when I take the Albendazole there are so many flukes to take up the medicine, it doesn't have the impact it should.
I finally found that moxadectin works (but it is very serious drug. See my posts). I've almost killed off all scattered roundworm with one round of moxidectin (double dose). You take it only once a month as it stays in the system for 20 - 40 days. I think my next dose will finish them off.
