After the implementation of the "new ten" national epidemic prevention and control measures, how to conduct self-management health at home? Especially for the possible "self medication", how to eat the medicine reserved by the family? What should pregnant women, the elderly and children pay attention to when taking medicine? In response to these concerns, the Pharmacy Department of Zhongshan Hospital affiliated to Fudan University issued a reminder. Experts from the pharmacy department of Zhongshan Hospital said that for COVID-19 asymptomatic or mild infected persons without serious underlying diseases, or infected persons with stable underlying diseases who do not have serious heart, liver, lung, kidney, brain and other important organ dysfunction that require hospitalization treatment, it is recommended to treat at home, take more rest, drink more water, and strengthen their own immunity. Symptomatic patients are usually treated symptomatically. Reminder 1: Most of the medicines prepared at home are over-the-counter medicines. When there is no need to prescribe medicines at home, the medicines that the citizens may need include several aspects. For example, for fever symptoms, commonly used drugs include acetaminophen, ibuprofen, aspirin, Jinhua Qinggan granules, Lianhua Qingwen granules/capsules, Xuanfei Baidu granules, Qingfei Paidu granules, Shufeng Jiedu capsules, etc. For another example, for dry throat and sore throat symptoms, Diquine ammonium chloride, Liushen pill, Qingyan dropping pill, Shufeng Jiedu capsule can be selected; For cough and expectoration symptoms, bromhexine, ambroxol, guaifenesin and acetylcysteine can be selected; For dry cough without sputum, Folcodine and dextromethorphan can be selected; For runny nose, chlorpheniramine, loratadine, cetirizine, etc. can be selected; For nasal congestion, the siloxazoline nasal drops can be selected; For nausea and vomiting, Cinnarizine and Huoxiang Zhengqi Water/Capsule can be selected. It should be noted that most of these drugs are OTC drugs, which are relatively safe, and do not need to register in the hospital or ask a doctor to write a prescription for drugs. Patients can judge, purchase and use them by themselves. In addition, it can also be seen that there are many kinds of drugs to choose from, so the citizens need not keep an eye on individual "online drugs", let alone be anxious because they have not captured "online drugs". Reminder 2: Select appropriate drugs to prevent overdose, so as to avoid adverse reactions. When taking these drugs, the pharmacist of the Pharmacy Department of Zhongshan Hospital reminded us that we should remember some precautions. First of all, for different symptoms, choose the appropriate drugs, do not repeat medication. For example, if you buy a compound preparation or a Chinese patent medicine containing western medicine ingredients, you must read the instructions carefully. It may have the same drug ingredients, and you should prevent repeated or excessive use of similar drugs. Secondly, the daily dose of acetaminophen should not exceed 2g, and it should not be taken more than 4 times within 24 hours; Ibuprofen should be taken according to different dosage forms and drug instructions. It should not be used for more than 3 days to reduce fever. In addition, do not take Lianhua Qingwen Granules/Capsules if you have diarrhea symptoms; Chlorphenamine, loratadine, cetirizine, etc. may have drowsy side effects. Do not drive or do other work requiring high concentration during taking the medicine; Huoxiang Zhengqi Water contains alcohol. People with alcohol allergy should not take it. It should not take it together with some cephalosporins, metronidazole and other drugs to avoid adverse reactions. Reminder 3: Before using drugs for pregnant women and other special groups, it is better to consult a professional doctor
