The best medicine for bronchitis depends on whether it’s acute or chronic. Acute bronchitis, often caused by viruses, usually improves with rest, fluids, and over-the-counter remedies such as cough suppressants, expectorants, or pain relievers like ibuprofen. Chronic bronchitis, linked to conditions like COPD, may require prescription inhalers, steroids, or antibiotics if bacterial infection is present. Understanding the best medicine for bronchitis helps patients choose effective relief while knowing when to seek medical care for lasting symptoms.
