You can take Merlin for fever of 38℃, but 38℃ is a low fever and it is recommended to first cool down with physical cooling methods, such as alcohol wipes, warm water baths and using antipyretic patches. If the patient has a history of febrile convulsions, the temperature needs to be controlled as soon as possible, and Merlin can be taken to quickly lower the temperature. The main ingredient is ibuprofen, which is the most widely used antipyretic in the clinic. It is a safe antipyretic for adults and children, with fast action and few side effects, but it should be noted that there should be an interval of more than four hours between each dose, and children should be medicated according to their weight.
