How long does it take for an antibiotic to work?
Mild to Moderate Infections: For most common infections like urinary tract infections (UTIs), sinusitis, or skin infections, people may start noticing improvement within 24 to 72 hours of starting the antibiotic.
Severe Infections: In cases of severe bacterial infections (e.g., pneumonia, sepsis), noticeable improvement might take longer, often 3 to 5 days, depending on the antibiotic and treatment approach.
