When a child has a fever, in the end can antipyretic drugs be used alternately, in addition to whether it is necessary to alternate, has been the problem of many parents confused, today to popularize this issue. The first thing to make clear is that the purpose of using antipyretic drugs is not necessarily to quickly and completely reduce the child’s temperature to the normal range, many children will have a drop in temperature after the use of drugs, but not completely to below 37 degrees, as long as the child does not have convulsions, good spirit, does not affect other activities, etc., can be completely observed again, do not have to rush to the child with too much antipyretic drugs. I personally believe that it is possible to alternate acetaminophen and ibuprofen when a child has a fever, but whether or not you need to alternate them depends on the situation. Under normal circumstances, acetaminophen and ibuprofen are both safe for children and are the preferred antipyretic medications. Many guidelines state that both medications are good for reducing fever and making your child feel comfortable, but acetaminophen is generally recommended for low fevers and ibuprofen is recommended for high fevers, where it is more effective. However, the need for alternate use depends on whether one antipyretic is able to ensure that the child’s fever is reduced. Currently, the American Academy of Pediatrics recommends that acetaminophen be used no more than 5 times a day, once every 4 hours, while ibuprofen is recommended no more than 4 times a day, with an interval of 6-8 hours before it can be used again. This is absolutely safe in terms of frequency of use. If a child has a fever and uses an antipyretic, for example, acetaminophen, it is best to wait 6 hours before using acetaminophen again. If a child has a fever that may be severe and within 6 hours he or she may have a high fever, i.e., a temperature that exceeds 38.5 degrees or 39 degrees again, it is not appropriate to use the same antipyretic again, and if the child has significant discomfort and needs another antipyretic, it is recommended to alternate with another antipyretic, such as ibuprofen. In other words, the same class of antipyretics is recommended to be used more than 6 hours apart and no more than four times a day. However, if the child’s condition is relatively severe and requires more frequent use of antipyretics, then it is possible to switch to another type of antipyretic at intervals of about three hours. Acetaminophen and ibuprofen together can be used eight times in a 24-hour period, with a minimum interval of three hours between doses. However, if the child has had another fever more than 4-6 hours apart, it is not recommended to alternate between fever-reducing medications, and it is recommended to use only one type of fever-reducing medication, which is also recommended by mainstream guidelines at home and abroad, because if different types of fever-reducing medications are used alternately, it is easy to use the wrong medication, such as forgetting which one to take or simply taking the wrong medication, which can cause potential side effects This can lead to potential side effects. Therefore, on the question of whether two kinds of antipyretic drugs can be used alternately, I think it is perfectly fine, but parents should pay special attention to place and label the drugs clearly, and record the time and type of drugs and dosage in detail after each dose, so as to be clear when the drugs are used again, and never have the problem of taking the wrong drugs. At the same time, I would like to advise that most children actually do not need to alternate the use of antipyretic drugs, if one antipyretic drug can control the child’s body temperature, there is no need to alternate the use of two drugs, which is the aforementioned can not be a problem, but the need is the problem.
