My daughter has the dreaded... threadworms. It makes me feel so icky! Monday night, I gave her a one-off dose of Ovex suspension. The following morning, I hot washed every item of clothing, bedding, towels, throws, cushions, teddies etc. I even disinfected all her toys, the kitchen and bathrooms. I've made her sleep in knickers and showered her in the morning and before bed. However.. last night (tue night), I checked her bum, and there were sooo many worms crawling out still!! is that normal after 24 hours??? The pharmacist said they should be dead by now, but the instruction leaflet said it can take a few days. I am so worried and stressed.
