Introduction

If tonsillitis is confirmed by examination to be caused by a streptococcal infection, and the patient presents with obvious symptoms such as sore throat, fever, and pus formation in the tonsils, and has no history of penicillin allergy, administration of penicillin can effectively inhibit bacterial proliferation, making it suitable for treatment. If the tonsillitis is caused by a viral infection, or if the patient has previously experienced allergic reactions to penicillin such as rash or difficulty breathing, penicillin should not be used.

Penicillin is generally suitable for the treatment of tonsillitis when it is caused by streptococcal infection and there is no history of allergy. It is not suitable for treatment if the infection is viral or if there is a penicillin allergy. If in doubt, it is recommended to seek medical advice in advance. Detailed analysis is as follows:

If tonsillitis is confirmed through examination to be caused by streptococcal infection, with symptoms such as significant sore throat, fever, and pus formation in the tonsils, and there is no previous history of penicillin allergy, penicillin can effectively inhibit bacterial growth and is suitable for treatment.

If tonsillitis is caused by a viral infection or if the patient has previously experienced allergic reactions to penicillin such as rashes or difficulty breathing, using penicillin will not only be ineffective but may also trigger severe allergic reactions. In such cases, penicillin is not suitable for treatment.

After experiencing symptoms of tonsillitis, avoid self-medicating with penicillin. When seeking medical care, actively inform the doctor about any allergy history. After examination to determine the type of infection, follow medical advice in selecting appropriate medication. Monitor your body's response during medication, and discontinue use and seek medical attention promptly if any discomfort occurs.
