If a child has a fever and takes Merlin 5 times in 24 hours, there is usually not much of a problem. There are also other fever-reducing medications available for children with fever, such as acetaminophen. The main ingredient of Merlin is ibuprofen, and another acetaminophen is also a rapid fever reducer. You can also alternate the two antipyretics, taking each one 4-6 hours apart. It is recommended that each type of antipyretic medicine should not be taken too often each day, usually around 4 times. After taking antipyretics, parents are advised to give their children plenty of water and strengthen physical cooling by taking warm baths and applying antipyretics to promote a drop in body temperature. Parents should pay attention to the child’s mental state and other manifestations. If the child is not in good spirits or has a heavy cough and other clinical symptoms, parents are advised to take the child to the doctor as soon as possible.
