新冠病毒感染用药指南
Below are the medicines that are recommended in the National Diagnosis and Treatment Guidelines (9th version).
Due to the current shortage on some medicines, experts have also made a list with supplements, which covers 67 Chinese medicines with classic herbs and 41 chemical medicines in total, most of which can be available from retail pharmacies, e-commerce platforms and various other channels.
In addition to medication, we need to have a good rest and drink more water to fight against COVID-19. According to the self limited characteristics of the virus, ordinary people will generally recover within 1-2 weeks. If you have high fever at home for more than three days and still have no relief, or even other symptoms become more and more severe, and you have obvious shortness of breath, dyspnea after activities, you should go to the hospital immediately.
除了用药，对抗新冠病毒更需要好好休息、多喝水。根据病毒自限性的特点，普通人一般1-2周就会控愈。如果在家出现高热超过三天了仍没有缓解，甚至其他症状越来越重，有明显呼吸急促、喘憋，尤其是活动后憋气的情况，应立即前往医院就诊。
