Tell the mother how much of the drug she should give her child. This means communicating clearly how many times per day, when and for how many days the drug should be given to her child. You should also explain to the mother that if her child is vomiting, she should give the drug even though the child may vomit it up. Tell her to watch the child for 30 minutes. If the child vomits within the 30 minutes (the tablet or syrup may be seen in the vomit), give another dose. If the child is dehydrated and vomiting, she should wait until the child is rehydrated before giving the dose again.
