Hello. My family have been battling threadworm for 3 months now. In the last 2 months I havens seen any adult worms in any of us but lots of white flakes in our underwear, it looks like tonnes of dandruff. It s always worse at the end of the day rather than when we change in morning. We ve had lots of mebendazole but the dandruff like itchy stuff keeps coming out every day. We keep taking mebendazole every 12 days as I m worried it s newly hatched worms and they ll grow into adults. Am I right to keep medicating my family? We ve been to gp 3 times and we re told there s nothing they can do to help us. Did 1 test it came back negative for ova.
