Ds had threadworms last week, and everyone but me was dosed with ovex. I was told by nhs direct they couldn't give me anything but to go to the dr if I wanted treatment. I did and she gave me pripsen as it has no known effects on baby (I'm 16 weeks) I took this before looking it up on the net and now have scared myself silly that I've harmed the baby. Has anyone else taken Pripsen before in the second trimester and all been ok? Thanks
