What is Cephalexin and How Does it Work?
Cephalexin is a first-generation cephalosporin antibiotic. It combats bacterial infections by interfering with the bacteria’s ability to build cell walls. This process weakens and ultimately kills the bacteria.
Specifically, cephalexin inhibits the synthesis of peptidoglycans, crucial components of bacterial cell walls. Without these, bacteria are vulnerable and cannot survive.
- Cephalexin targets a wide range of Gram-positive bacteria, such as Staphylococcus aureus (including methicillin-sensitive strains) and Streptococcus pyogenes.
- It’s also effective against some Gram-negative bacteria, including Escherichia coli and Proteus mirabilis.
The drug is administered orally, typically in capsule or tablet form. Your doctor will determine the appropriate dosage and duration of treatment based on your specific infection.
- Always follow your doctor’s instructions precisely. Do not stop taking the medication prematurely, even if you feel better.
- Complete the full course to ensure complete eradication of the bacteria and prevent resistance development.
Potential side effects, while uncommon, include diarrhea, nausea, and stomach upset. Serious side effects are rare but require immediate medical attention. Consult your physician if you experience any concerning symptoms.
Common Uses of Cephalexin: Treating Bacterial Infections
Cephalexin effectively combats various bacterial infections. Its common applications include:
