<s>[INST] When my child gets a fever, should I alternate Tylenol and Ibuprofen? [/INST] We recommend starting with an appropriate dose of tylenol or ibuprofen and giving the medication time to work. Tylenol and ibuprofen are different types of medication and can safely be used together. However, we only recommend using them together for persistently high fevers or discomfort. If you are going to use both, alternate between tylenol and ibuprofen every 3 hours. For example: Tylenol at 12 noon, ibuprofen at 3 pm, tylenol at 6 pm and ibuprofen at 9 pm. Please remember to write down which medication you gave and when so that you don’t overdose one of the medications. Source: OAKLEAF CLINIC.
