Bacterial infections are commonly treated with antibiotics, selected based on the organism, infection site, and patient factors. First-line options may include penicillins, cephalosporins, macrolides, or fluoroquinolones, depending on sensitivity patterns. For mild to moderate skin, respiratory, or urinary infections, oral agents are often effective, while severe cases may require intravenous therapy. Supportive care hydration, rest, and symptom control also aids recovery. Proper diagnosis and completing the full antibiotic course are critical to prevent resistance. In pharmaceutical supply contexts, medications such as cephalexin capsules wholesale are widely distributed for appropriate, prescription-based use.
