DD has threadworms. It has been 5 days since we all took Ovex but she is still itching rampantly:. Is this normal? We have been changing and washing bedding, clothes, pyjamas, towels etc on 60 since we found out with frequent handwashing. It doesn’t seem to be doing anything. We also coat her in sudocrem to help with the itching but it’s still really bad and keeping her awake. Advice please!
