For viral colds that are caused by the influenza virus, consider taking both oseltamivir (i.e., oseltamivir phosphate) and Chuanbei Loquat Cream. Oseltamivir phosphate is an antiviral medication indicated for the treatment of influenza A and B in children and adults aged ≥1 year and for the prophylaxis of influenza A and B in adolescents and adults aged ≥13 years. The drug needs to be contraindicated in people who are allergic to the product and those with severe renal insufficiency, and common adverse reactions include nausea, vomiting, insomnia, rash, and dizziness. Pei Pa Koa Cream is a proprietary Chinese medicine with the efficacy of clearing heat and promoting the lungs, resolving phlegm and relieving cough. It is suitable for the treatment of chest tightness and distension, swelling and pain in the throat, cough with yellow sputum and unpleasant sputum, as well as colds and bronchitis accompanied by the above symptoms due to wind-heat violating the lungs and phlegm-heat internal obstruction. Contraindications and adverse reactions are not clear. Oseltamivir phosphate is mainly used to inhibit viral replication, while Pei Pa Koa Ointment can relieve symptoms such as cough, phlegm and sore throat caused by colds. There is no clear indication of drug-drug interactions between the two, so they can be used simultaneously in the treatment of patients with influenza. If the symptoms of cold and flu are severe, it is recommended to consult a doctor in time and follow the doctor’s instructions, not self-medication to avoid adverse reactions.
