What is the recommended antibiotic for cellulitis and mastitis?

Keflex, also known as cephalexin, is a first-generation cephalosporin antibiotic that is commonly used to treat skin infections, including cellulitis and mastitis. These conditions often arise from bacterial infections, and the organisms responsible are frequently susceptible to this antibiotic.

Keflex works by inhibiting the synthesis of bacterial cell walls, leading to cell lysis and ultimately the death of the bacteria. It has good activity against streptococci and staphylococci, which are the primary pathogens involved in cellulitis and mastitis cases. The oral bioavailability and safety profile of Keflex also make it a preferred option for outpatient management of these infections.

In contrast, while Augmentin (amoxicillin-clavulanate) may be effective for some bacterial infections, it is more traditionally indicated for specific types of infections and may not have the same coverage for the most common pathogens causing cellulitis and mastitis as Keflex does.

Doxycycline is typically used for various other infections, particularly those caused by atypical organisms, and while it has some effectiveness against skin infections, it is generally not the first-line choice for treating cellulitis and mastitis.

Clindamycin is a good option for skin infections,
