Cephalothin is a broad-spectrum antibiotic that belongs to the first generation of cephalosporins. Although it is effective against a variety of bacterial infections, it is no longer commonly prescribed due to its side effects and resistance to some bacteria. As a result, medical professionals may use alternative antibiotics with similar properties, such as cefazolin, cephalexin, or cefadroxil. These drugs may be preferred due to their better safety profile and efficacy against resistant strains. Other possible synonyms for cephalothin include cephaloridine and cefacetrile. However, medical professionals should consult guidelines and consider the patient's medical history and condition before choosing an appropriate antibiotic.
