It helps to alternate ibuprofen and Tylenol to break fevers. Also one reason most cold and flu medicine have acetaminophen in them. It is really good at helping break fevers as well as pain. Plus alternating them uses two organs a little instead of one heavily.They did the flu said it was negative. Stuck one thing up one nose hole and another up the other haha. Flu test came back in just a couple of minutes, Covid have to wait on it to come back. Only thing Iv been taking is ibuprofen 200 are 400 mil. It’s help out a lot.
