Oral Antibiotics in Dermatology

What are oral antibiotics?

Oral antibiotics are medications designed to treat bacterial infections like cellulitis and are frequently used in the field of dermatology. While they are commonly employed to manage post-surgical infections, they are also used for treating skin conditions complicated by secondary bacterial infections, such as infected eczema. The range of antibiotics used in dermatology is broad, with cephalexin (Keflex), trimethoprim-sulfamethoxazole (Bactrim), clindamycin, and amoxicillin-clavulanate (Augmentin) among the commonly prescribed types. For chronic skin conditions like acne and rosacea, tetracycline-class antibiotics such as doxycycline and minocycline are often favored.

What are possible side effects of oral antibiotics?

The side effect profile for antibiotics is diverse but generally includes gastrointestinal disturbances like nausea and diarrhea. Allergic reactions are another consideration; these can manifest as hives or a more generalized rash. Patients with a known history of allergic reactions to certain antibiotics should communicate this to their healthcare provider to avoid cross-reactivity with similar drugs. If any of these side effects become severe, medical advice should be sought for appropriate management and potential medication switch. Due to the wide array of antibiotics, each has its own specific set of side effects that may extend beyond those mentioned here.

How are oral antibiotics used?

Oral antibiotics should be taken precisely as prescribed to ensure effective treatment. Completion of the full course is critical, even if symptoms resolve earlier, to prevent bacterial resistance and recurrence of infection. During your consultation, a bacterial culture or swab may be obtained to identify the offending bacterial strain accurately. If culture results indicate that the infection is caused by a different type of bacteria than initially suspected, a switch to a more appropriate antibiotic may be recommended.
