What medication should be taken for sore throat and cough caused by influenza B?

Sore throat and cough caused by influenza B are generally triggered by exposure to cold, and are usually accompanied by symptoms such as fever, cough with excessive phlegm, and sometimes may involve lung infection. First, patients with sore throat and cough should get adequate rest and increase physical strength, drinking more warm water appropriately. Second, consume more warming and nourishing foods, such as red dates, millet, goji berries, eggs, lean meat, tofu, seaweed, lily bulbs, longan, lotus seeds, and sweet pears, which help improve immunity and strengthen the body. Third, appropriate use of anti-inflammatory and anti-infective traditional Chinese medicines, such as Xiao'er Duo Bing San, can be helpful. In the early stage, nitroglycerin oral solution and antiviral oral solution may be used; in the middle stage, antiviral oral solution containing higher levels of antiviral ingredients can be used, which also helps relieve sneezing and fever. Finally, it is important to maintain hydration, as patients with sore throat and cough are particularly prone to dehydration. Timely supplementation of calcium, vitamins, and other nutrients can promote recovery.
