Ibuprofen suspension drops, which are mainly used for fever reduction in infants and children, have few side effects and are relatively safe. They can take effect half an hour after oral administration and can be repeated every 6-8 hours if necessary, but no more than four times every 24 hours. In addition, parents should note that the dose should not exceed the recommended dose, otherwise it may cause headache, vomiting, lethargy, hypotension and rash. In case of overdose, the child should immediately consult a doctor. The main component of the drug is ibuprofen, a non-steroidal anti-inflammatory drug that inhibits the synthesis of prostaglandins (prostaglandins can cause fever in the body) to reduce fever. However, you should not take other antipyretic and analgesic drugs on your own while taking this drug, as it may increase the possibility of adverse reactions and ulcers in the gastrointestinal tract. In addition, the use of ibuprofen suspension drops to reduce fever at the same time can also take physical cooling methods to promote antipyretic efficacy. Specifically as follows: 1, local warm and wet compresses: prepare a warm towel or antipyretic paste and place it on the forehead, top of the head and body surface where the large blood vessels flow through (both sides of the neck, armpits, groin, etc.) for 15-30 minutes; 2, warm bath: control the water temperature at about 37 ℃ and soak for 10-15 minutes, which can also play a cooling effect; 3, drink more water: drink water to help accelerate sweating and urination to achieve the purpose of cooling.
