Typically you will kill parasites from small to big. Take a broad spectrum. Mebendazole and albendazole target many parasites. Take the highest dose allowed in cycles. Combining meds in different combos albendazole, ivermectin, alinia, pyrantel, fenbendazole. Just pick two that work of different pathways. works better for the larger parasites and taking them for longer times is even better. The pin worms will be the most persistent but easy to kill. The trouble is they reinfect you so easily. They key is persistence. Never let them rest. If you arent doing rounds of meds then do herbals or foods they dont like. It takes time but you will win.
