We are missing all sorts of info. What is your daughter’s age, weight, how many days has she been taking it, how many times a day, what is she sick with?
I don’t understand not being able to get in touch with a doctor, can’t you have him paged?
I looked up the drug, I am not very familiar with it, and it says to take at least a half before a meal, but it also says reduced absorption when taken with food, so sometimes that means taking it with food is ok. Food often prevent nausea with a lot of antibiotics, but you would need to know if it is ok to do. Some drugs you can do it, and some it is an absolute no no. Have you tried giving her food as soon as she is allowed to eat? Check what I have said here with a pharmacist, don’t trust what I looked up, but do try eating as soon as possible.
She very well might be overmedicated, but stopping the drug early can mean she will not get rid of the bacteria and she will have to start all over again on a new antibiotic for a full course if that happens. I saw some dosage recommendations that said that drugs should be started on a loading dose initially of 250 for children and then reduced to 125. is she taking the capsule? If so you cannot “split” a capsule in any way shape or form. If she is taking the liquid you can reduce it if a pharmacist can give you information on typical dosage, taking her weight into consideration. It would be better if a doctor switched her medication probably. If you have the capsule and the information you get from the pharmacist is she is being overdosed, then I would space out the dose a little. If she is taking it three times a day, I would give it to her every 10 hours, but then you have to really watch the clock and set alarms.
I am NOT a doctor, this is just what I would do for myself. Under medicating an infection again can mean having to start all over again on a new full corse of antibiotics. But, if it is like taking poison when she takes it, she should not be suffering so much from an antibiotic. Women and children are often overmedicated. The best solution is contacting a medical professional who can advise you accurately on whether it is reasonable to reduce the meds, and if not, then switch her to another med without interruption so she does not have to start all over.
