If your baby has a recurring fever, you can’t keep taking antipyretic medication, which should be taken at intervals of 4-6 hours before repeating the medication. If there is a recurring fever, it is important to find out the cause of the fever to be treated, not simply rely on antipyretic drugs, antipyretic drugs, if you take too much, there will be some side effects. Most fever-reducing drugs are non-steroidal anti-inflammatory drugs (NSAIDs), which, if taken in large quantities, can cause a decrease in the number of white blood cells or coagulation dysfunction, and some NSAIDs can also cause damage to the gastrointestinal mucous membrane, resulting in gastric hemorrhage. Although all of these complications are relatively rare, they can still occur if you take too much of the drug. The first step is to check the blood count and C-reactive protein. If there is an elevated white blood cell count in the blood count, the fever is often caused by a bacterial infection and needs to be treated with antibiotics. If there is a simple increase in C-reactive protein, the fever is often caused by a viral infection and requires the use of antiviral medication, such as ribavirin.
