Keflex, or Cephalexin, fights ear infections by targeting the bacteria responsible. It’s a cephalosporin antibiotic, meaning it works by inhibiting bacterial cell wall synthesis. Specifically, it interferes with the formation of peptidoglycan, a crucial component of the bacterial cell wall. This disruption weakens the bacterial structure, leading to cell death and preventing bacterial reproduction.
Targeting Common Ear Infection Bacteria
Keflex effectively combats many bacteria commonly causing otitis media (middle ear infection), including Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. However, its efficacy depends on the specific bacteria involved, and antibiotic susceptibility testing might be necessary in certain cases. Your doctor will consider this when prescribing Keflex.
Important Considerations
Remember to complete the full course of Keflex prescribed by your doctor, even if symptoms improve. Stopping early can lead to recurring infection and the development of antibiotic resistance. Also, report any allergic reactions or side effects immediately. Common side effects include diarrhea, nausea, and vomiting. Discuss any concerns with your doctor or pharmacist before starting Keflex.
