A course, and everyone helping.
RxReminders keeps a child's short course and fever doses in one record, with the amount, the concentration and who gave each dose.
A short course, day by day
Enter a course like 10 days of amoxicillin and the app counts the days. A taper or a changing amount follows the steps you enter.
The dose helper, for the middle of the night
In the US and Canada, the dose helper works out an amount of children's acetaminophen and other common medicines from the child's weight, age, the concentration on the bottle and the cup or syringe in the box. It works on a fresh install, without an account or a network connection. When it can't give a number, it says why and what to do now.
Not medical advice. This is a calculator, not a diagnosis: it states what the medication data says for the weight, age and concentration you entered. Check the product label and consult your clinician or pharmacist.
The school nurse can confirm a dose
Send the school nurse or a sitter a link. They confirm a dose in any browser, and it's logged under their name, so everyone sees it was given.
