- Tetracyclines, like tetracycline and doxycycline, should not be taken with milk, iron, or antacids due to absorption issues and should be avoided in children under eight and pregnant women to prevent bone development problems.
- Aminoglycosides, such as gentamicin and neomycin, require monitoring for renal and ototoxicity, while macrolides like azithromycin and erythromycin can lead to QT prolongation and increase the risk of C. difficile infection, highlighting the importance of understanding antibiotic side effects for safe and effective treatment.
