Daptomycin is an antibiotic used to treat serious bacterial infections, particularly those caused by gram-positive bacteria. It works by disrupting the bacterial cell membrane, leading to cell death. Daptomycin is often prescribed for conditions like skin infections and bloodstream infections, especially when other antibiotics are ineffective. This medication is typically administered through an intravenous (IV) infusion and is usually reserved for cases where other treatments have failed or when patients have specific allergies. Common side effects may include muscle pain and elevated creatine phosphokinase levels, which should be monitored during treatment.
