What antibiotic would be used for the treatment of cellulitis?

The treatment of cellulitis typically involves the use of antibiotics that are effective against the bacteria commonly responsible for the infection, primarily Staphylococcus aureus and Streptococcus species. Keflex, known generically as cephalexin, is a first-generation cephalosporin antibiotic. It is particularly effective against both of these types of bacteria, making it a suitable choice for treating uncomplicated cellulitis.

Keflex is orally administered and has good tissue penetration, which is important for treating skin and soft tissue infections like cellulitis. Its efficacy against gram-positive bacteria, which are the primary pathogens in cellulitis, supports its selection as an ideal treatment option.

While Augmentin is also a good antibiotic with broader coverage, it is typically reserved for cases where there is a concern for resistant organisms or where a polymicrobial infection is suspected. Ceftriaxone, a third-generation cephalosporin, is commonly used for more severe infections or in settings where intravenous therapy is required. Flexeril, primarily used as a muscle relaxant, does not have any antibacterial properties and would not be suitable for treating cellulitis. Therefore, Keflex stands out as the most appropriate choice for this condition.
