Penicillin is a commonly used and classic antibacterial drug with bactericidal and anti-inflammatory effects, and is commonly used in the treatment of various inflammatory diseases.

However, some patients may induce interstitial nephritis after applying penicillin, or affect the renal tubular epithelial cells of the patients, leading to kidney injury. Although the probability of such cases is relatively small, people need to be alert to the possibility of penicillin causing harm to the kidneys and should not abuse penicillin. Meanwhile, the dosing interval should be extended or the dose should be adjusted for those with severe renal impairment.
