my 5 year old daughter had a bout of diarrhoea about 5 weeks ago with very pale stools and abdo pain, since then she has had intermittent episodes of diarrhoea with abdo pain. The other day she came home from school and said she saw a worm in the toilet she drew a picture of it and it looked about 2inches in legnth and 1/8 inch in width. She then was on and off the toilet and passed quite a bit of mucous. I have since been to the doctor who has sent off a specimen and said it is possible its thread worms, I suspected Gardia. The doctor also mentioned testing for coeliacs if the stool specimen comes back negative for parasites. The doctor reluctantly wrote a prescription for vermox I think she would have preferred to wait for the specimen but I explained we were off on holiday in a week and wanted to treat her just in case. Would vermox treat gardia as well.
