How Long Does It Take for Antibiotics to Work?

Most antibiotics begin working within 24 to 72 hours of starting treatment. You'll typically notice symptom improvement within 2-3 days as the medication reduces bacterial load in your system. However, it's crucial to complete the entire prescribed course, even if you feel better. Studies show that 95% of bacterial infections respond to appropriate antibiotics within this timeframe. The exact duration depends on infection type, severity, and your immune system. Respiratory infections often improve within 48 hours, while urinary tract infections may show relief in 24-48 hours. Never stop antibiotics early, as this can lead to antibiotic resistance and infection recurrence.
