What is the best antibiotic for bronchitis, i've been taking clendamycin but its not getting any better.?

None: Despite the fact that antibiotics are frequently used for bronchitis, it's viral more often than not. That means antibiotics don't work, but the illness can get better over time.

Treat the underlying: Cause.Bronchitis is inflammation of the lungs not infection therefore no amount of antibiotics is going to cure it unless with overlapping pneumonia! generally you will need a bronchodilator, inhaled or oral steroid depending on severity and /or mucolytics to get you better! discuss with your doctor please.

Other considerations: If you have smoked currently or in the past, or have had a cough for more than three weeks, I would suggest considering other causes as well. These may include reactivity of your airway, reflux or sinusitis/pneumonia. Your physician may order lung function tests and/or a follow up chest radiograph. Most episodes of bronchitis are viral rather than bacterial.
