First-Line Treatments

For most cases of cellulitis, doctors prescribe antibiotics that target the most common bacteria causing the infection. These typically include penicillin-based drugs like dicloxacillin or flucloxacillin, or cephalosporins like cephalexin. These medications are usually taken orally for 5-14 days, depending on the severity of the infection.

When MRSA is a Concern

If there's a risk of methicillin-resistant Staphylococcus aureus (MRSA), different antibiotics may be prescribed. These might include trimethoprim-sulfamethoxazole, doxycycline combined with another antibiotic, or in some cases, linezolid. Your doctor will assess your risk factors for MRSA before choosing the most appropriate treatment.
Antibiotics are used to treat cellulitis by targeting the common bacteria causing the infection. First-line options include penicillin-based drugs and cephalosporins, while MRSA concerns require alternative antibiotics.

Intravenous Options

Severe cases of cellulitis may require hospitalization and intravenous (IV) antibiotics. Common IV options include vancomycin, which is effective against MRSA, or beta-lactam antibiotics like cefazolin or nafcillin. Once the infection starts to improve, patients can often switch to oral antibiotics to complete their treatment course.

Dealing with Allergies

For patients with penicillin allergies, alternative antibiotics are available. These might include clindamycin or macrolides like erythromycin. However, it's important to note that many people who think they're allergic to penicillin actually aren't, and can safely take these medications after proper testing.
