What medication should I take for chills? First of all, the specific cause of the chills should be clarified. For chills caused by an infection that raises the body temperature, the infection needs to be treated. If it is a viral infection, you can consider taking Shuanghuanglian Oral Liquid or Oseltamivir. If it is a bacterial infection, it should be treated with a drug that is sensitive to the bacteria. In the case of gram-positive cocci, penicillin and first-generation cephalosporins may be used. In the case of gram-negative bacilli, third-generation cephalosporins or aminoglycoside antibiotics may be used, depending on the patient’s general condition, renal function, and age. If generalized chills are caused by anemia, more iron-containing foods need to be consumed, such as lean meat, spinach, jujube, and Agaricus. Oral ferrous fumarate can also be taken if necessary to correct the symptoms of anemia. If the chills are caused by hypothyroidism, you should eat more iodine-containing foods, such as seafood like kelp and nori. Sodium levothyroxine tablets can also be taken orally to restore thyroid function to normal levels. If it is caused by heart disease or liver disease, it needs to be treated according to the specific cause, such as cirrhosis of the liver should be given to protect the liver. If it is caused by hepatitis B, active antiviral treatment should be given, such as oral entecavir and adefovir. For cardiovascular, such as angina pectoris and myocardial infarction, symptoms should be improved by wearing more clothes as well as by giving treatments to activate blood circulation and remove blood stasis, dilate blood vessels, and anticoagulate. Oral medications may include isosorbide mononitrate as well as aspirin.
