38.5°C以下通常不必用药。一般腋下温度超过37.2°C定义为发烧。对于绝大多数3个月以上的宝宝以及成人而言，轻度发烧本身并不危险。 腋下温度38.5°C以下的患者，如果精神状态尚好，学习、工作未受影响，没必要用药。此时，可用物理降温方法，包括洗温水澡或用温水浸过湿热的毛巾擦拭 身体。
普通发热建议只用1种药。安全性高的退烧药有对乙酰氨基酚和布洛芬。对乙酰氨基酚(如泰诺林、必理通等)是退烧药首选，适用于3月以上的儿童和 成人，合理使用安全性高，但过量使用可能造成肝脏损害。布洛芬(如美林、芬必得等)退烧作用较强，会导致大量出汗，不适用于有脱水症状者，肾功能不好者也 要慎用。
当一天只需要服2~3次退烧药就能缓解时，最好只用1种药。因为每增加一种药品，就会使吃错药的风险增加一倍。同时，一旦出现药品不良反应，很 难鉴别是哪种药物导致的，会增大治疗的难度。退烧药起效的时间因人而异，一般0.5~2小时内见效。家长如果发现孩子服布洛芬后开始出汗，服对乙酰氨基酚 后哭闹减轻(可能是头痛等症状减轻)，证明药开始起效了，不要急着加药或者换药。
高烧不退交替使用退烧药时，注意间隔时间。如果正确用药仍然持续高烧不退时，可以考虑两种退烧药交替使用。例如对乙酰氨基酚用了2小时后烧没退 下来，但其最小用药间隔是4小时，这时，不能再用对乙酰氨基酚，只能将另一种退烧药布洛芬与其交替用。服两种药的最小间隔时间是2小时。因为通常一种退烧 药吃进去后，大约需要2小时才能达到有效治疗效果，如果2小时后体温仍然维持在38.5°C以上，可以理解为某一种药不能有效退烧，这时才需要和另一种药 交替使用。两种退烧药交替使用时，每天分别最多用4次。
