What antibiotic would likely be included for managing right lower extremity cellulitis?

Keflex, which is a brand name for cephalexin, is the antibiotic that would typically be included for managing right lower extremity cellulitis. Cellulitis is a common bacterial skin infection that often occurs in the lower limbs and is frequently caused by streptococcal and staphylococcal bacteria. Cephalexin is effective against these organisms and falls under the category of first-generation cephalosporins, which are commonly prescribed for uncomplicated skin infections, including cellulitis, due to their efficacy and safety profile.

Other medications listed are not appropriate for treating cellulitis. Pradaxa, an anticoagulant, is used for preventing blood clots and does not have antibacterial properties. Paxil is an antidepressant and does not play a role in managing infections. Phenergan is an antihistamine primarily used for nausea and allergies, and it does not address the underlying bacterial infection. Thus, the selection of Keflex represents an important choice in the management of skin infections like cellulitis, highlighting its role in healing and reducing the risk of complications.
