Doxycycline is the only tetracycline that can produce anti-inflammatory effects without evident anti-bacterial activity.
Take the entire prescription course of doxycycline hyclate prescribed by your doctor. Many people tend to stop taking antibiotic once their symptoms get better. Skipping doses or not completing the Doxycycline therapy may decrease the effectiveness of treatment and contribute to bacteria resistance.
