Children with fever often need to use antipyretic drugs, commonly used drugs such as Tylenol, Benadryl (acetaminophen); Merlin, Chen Gong Zaixin (ibuprofen); Riziqing (Nimesulide, children under 12 years of age are prohibited). When using the following items: 1, children’s viral colds and fevers tend to recur, so after using antipyretic drugs, the body temperature may also rise after a period of decline. If the child is in good spirits and plays as usual after the fever subsides, it is a good sign. If the child is in poor spirits again after the fever has subsided, simply give antipyretic medicine again. If the child is still in poor spirits after the fever subsides, you need to see a doctor again. 2, Most fever-reducing medications are OTC (over the counter, i.e., available on the shelf for anyone to buy without a doctor’s prescription), so the recommended dose on the drug’s instructions is actually very small (because it is often ineffective in reducing fever, taking into account individual weight differences in children of different ages and to prevent overdose by children or parents who do not know about the medication). However, when you take your child to the hospital to see the doctor, the doctor will give you a prescribed dose. This is precisely calculated based on your child’s actual weight and is usually effective in reducing fever. So take the medication as prescribed after your visit to the doctor. 3. Children with an axillary temperature greater than 38.5°C can be given fever-reducing medication. However, it is necessary to drink enough water containing minerals (such as oral rehydration salts) for the body temperature to drop, otherwise it is not effective. 4, do not take the same medicine repeatedly in a short period of time, it is easy to poisoning phenomenon. If it is necessary to use should be replaced by different antipyretic drugs alternately to reduce the chance of poisoning. 5, in some cases, the body temperature is not high or normal, it is also possible to take this type of drugs, of course, also need to drink enough water containing minerals. Doctors are using this class of drugs for anti-inflammatory or analgesic purposes. 6, These drugs are less likely to cause allergic reactions, but some children still have allergies, so inform your doctor when you see him. Children with asthma, G-6-PD, hepatitis, coagulation disorders, and cardiovascular diseases should not use this class of drugs easily.
