Ovex- double dose?

[princessllama]

Hi, we are struggling with continued threadworm infection. Anyone know if it is worth taking a double dose of ovex? Can this harm ?

What do you mean by double dose?

We had trouble with threadworms. We found all the hygiene stuff made no difference - it was almost impossible not to spread eggs when changing sheets etc. The only thing that worked was all members of the household taking a dose of ovex. Then taking repeating 2 weeks later to catch newly hatched eggs. (Once we even did this again 2 weeks after that). The worms took a few days to die. This method worked very successfully.
