DD age 6 has threadworms. Thankfully not bothering her much. Pharmacist gave ovex which she took 3 days ago but still seeing the little blighters and they are still alive! She's had a poo this evening with loads of them crawling on it. Is it normal for them not to be dead yet? Its not reinfection as its never stopped. I'm really worried.
YABU - just give it time, it's normal
YANBU - go back to the pharmacist
