The dosage of ibuprofen for 8 months old baby is 15mg/kg. When giving antipyretic medicine, you must consider applying antipyretic medicine only when the baby’s temperature is 38.5℃ or above, or when the baby does not reach 38.5℃ but has uncomfortable feeling or even crying and restless, this time 38.2-38.3℃ can also consider applying antipyretic medicine. There are two main types of antipyretics for children, including ibuprofen and acetaminophen, and whichever one you choose should be taken according to the instructions and as prescribed by your doctor. Antipyretics should be calculated according to weight, not given according to age, because some babies are fat and some are thin, and it is easy to overdose according to age. Domestic and international guidelines have found that the higher the fever, the more serious the condition. Many parents do not understand this and are anxious to see their baby’s fever, strongly urging the doctor to hurry to reduce the fever, when it is most likely to be over-treated. If a baby’s fever cannot be reduced immediately after taking medication, physical cooling can be done at the same time, for example, a warm bath is more effective.
