Influenza, or the common cold, can be self-treated in adults, but if it is more serious, medication is needed to avoid complications. Influenza is mainly caused by viral infections. Influenza can usually be cured on its own because adults have stronger immunity, so most of the infections can be cured on their own. However, if the infection is more serious, it cannot be cured by itself and requires timely medication to avoid complications such as pneumonia and meningitis. When patients with influenza have fever, they can take aspirin enteric-coated tablets, ibuprofen extended-release capsules and other non-steroidal anti-inflammatory drugs as prescribed by the doctor. For viral infections, neuraminidase inhibitors such as oseltamivir phosphate, paramivir sodium chloride injection, and zanamivir inhalation powder may be prescribed orally. Most adults with influenza can recover on their own, but if the patient’s condition is serious, it is necessary to consult a doctor in time and follow the doctor’s instructions for treatment.
