My daughter was prescribed laxido by the doctor for poo withholding but when I went to pick up the prescription the pharmacist said the dosage was way too high for a 21 month old. It was 2 sachets for 2 day's, 4 sachets for 2 days then 6 sachets for 2 days and then 8 sachets daily until impaction resolves. The pharmacist worried me and told me to give her one sachet a day and she has been going daily but still withholds as long as she can. I can't get in touch with the doctor and have been told he will ring me when possible so I've followed the pharmacists recommendation. She is pooing but not without a struggle as she tries so hard to hold it in. I do think it's a psychological issue but the doctor thinks it's due to impaction. I'm just so confused from the pharmacists reaction. Has anyone had an experience with poo withholding and what solved it?
