《伤寒论·辨太阳病脉证并治法上》
如果服了第一次药后汗出疾病痊愈，就停止服第二次、第三次药，不需要把一剂药都服尽。如果服第一次药汗不出，可以依照以上服药方法服第二次药。如果服第二次药还无汗出，那么，第三次药可适当提前服，可在半天左右将一剂服完。如果病情重的，可以白天夜晚服药，一天小时进行严密观察。
若一服汗出病差，停后服，不必尽剂；若不汗，更服，依前法；又不汗，后服小促其间，半日许，令三服尽；若病重者，一日一夜服，周时观之。
If sweat breaks out and the disease is cured after the first dose of medicine, stop the second and third doses. There is no need to take the whole dose. If no sweat breaks out after the first dose of medicine, you can take the second dose of medicine according to the above method. If no sweat breaks out after taking the second dose of medicine, then you can take the third dose a little earlier, and you can take it twice a day. If the condition is severe, you can take the medicine day and night, and observe it closely for an hour a day.
