Coughing up sputum that is white in color and sticky is mainly considered to be caused by bacterial or viral infections, and in the presence of mycoplasma infections, it may also cause this phenomenon. It is necessary to go to the hospital for routine blood tests, ultrasensitive C-reactive protein tests, and chest X-ray or CT lung tests to make a correct diagnosis based on the test results and other clinical manifestations. In case of viral infection, oral oseltamivir and ribavirin can be used, and in case of bacterial infection, cephalosporins or penicillins are also needed. If the condition is caused by mycoplasma, macrolides should be used to actively treat the condition. You also need to use drugs to stop coughing and resolve phlegm, you can take oral aminoglutethimide granules, or you can use powerful cough suppressant, orange capsule and other drugs to treat.
