it would not be wise to self-diagnose yourself as having a secondary bacterial infection from your recent viral illness and self-prescribed ampicillin. it would be advisable for you to be properly examined and diagnosed first by a medical professional. ampicillin is not used very much any more so it is unlikely that even if you did have a bacterial infection this would not be the antibiotic of choice. signs of secondary bacterial infection such as pneumonia as a result of a respiratory virus would be a high fever a worsening cough with expectoration of dark phlegm chest discomfort rapid respiration and lethargy. a mild sore throat or runny nose does not necessarily indicate a need for ampicillin.
how can i know if my cold/flu has become bacterial? so i can take a ampicillin? . i am aware that ampicillin does nothing if my cold/flu is a virus but i have been sick for a week now and although my body isn't sore/weak anymore i still cough up alot of mucus and coughing hurts my chest a bit and i have a sore throat also runny nose with alot of mucus as well.
