Introduction

If bronchitis is caused by infection with sensitive bacteria such as streptococcus, and symptoms such as cough with purulent sputum and fever are present, appropriate use of penicillin can inhibit bacterial proliferation and reduce the inflammatory response, thereby helping to alleviate the condition. However, if bronchitis is caused by a viral infection or by non-infectious factors such as allergies or smoking, penicillin has no effect on viruses.

Generally, penicillin may be effective for bronchitis caused by bacterial infections, but it is ineffective against bronchitis caused by viral infections or non-infectious factors. Detailed analysis is as follows:

If bronchitis is triggered by infection with susceptible bacteria such as streptococcus, causing symptoms like cough with purulent sputum and fever, appropriate use of penicillin can inhibit bacterial proliferation and reduce inflammatory responses, thereby helping to alleviate the condition.

If bronchitis is caused by a viral infection or triggered by non-infectious factors such as allergies or smoking, penicillin has no effect on viruses and cannot improve non-infectious inflammation. In such cases, its use is not only ineffective but may also increase the risk of adverse reactions.

Penicillin should be used under the guidance of a physician. A history of allergies must be confirmed before administration, and self-medication should be avoided. If symptoms such as rash or difficulty breathing occur during treatment, the medication should be discontinued immediately and medical attention sought without delay.
