Cephalexin is an antibiotic that belongs to the first generation of cephalosporin. It acts in a manner similar to penicillins and with an antimicrobial activity similar to that of Cefalotin, although less potent. Like other cephalosporins, Cephalexin prevents bacterial growth by interfering with the synthesis of the bacterial wall. Similar to the activity of penicillins, cephalosporins bind to the transpeptidase enzymes that are used to create links between the peptidoglycan chains (the polymers essential for the formation of the bacterial cell wall). In turn, the transpeptidase activity inhibits stability of the bacterial cell wall, resulting in the death of growing bacterial cells.

 

What is Cephalexin?

Cephalexin is used for the treatment of infections of the respiratory tract and the urinary tract, skin infections, otitis media as well as other infections. In case of severe infections, treatment with parenteral cephalosporins is advised.

Contraindications and warnings associated with the use of Cephalexin

Special attention should be reserved for patients with impaired renal function. It is important to inform your doctor if your diarrhea is persistent and they will recommend additional treatment options.  Although experimental studies have shown that the drug does not trigger severe side effects on the fetus during pregnancy, it would be appropriate to limit the use of Cephalexin to cases or real need and under the strict supervision of a medical specialist.
