Is doxycycline 100 mg good to take for a sinus infection?

Is doxycycline 100 mg good to take for a sinus infection?

In general no: Doxycycline is not generally a good antibiotic for rhino-sinusitis. If there is objective evidence of a bacterial infection (documented by culture) i would always recommend a culture and sensitivity of the lateral wall of the nose, particularly, is pus is present. Augmentin (amoxicillin and clavulanate) in patients not allergic to penicillin or Levaquin would be my recommendations. But a culture is required to make sure. ...Read more

Rx Doxycycline for Sinus Infection. Stopped after Side effects (pulsatile tinnitus). It’s been 3 weeks, pulsatile tinnitus not gone. Permanent?

Probably not doxy: Doxycycline is not a likely cause. More likely a coincidence that it started while taking the drug, especially since it has continued this long. If one of your sinuses is plugged and filled with fluid, that could result in pulsatile tinnitus by increasing transmission of blood flow sound in an artery. Discuss with your doctor, including if other tests are indicated. ...Read more

Small streaks of blood in phlegm/spit returned after 10 days on doxycycline for sinus infection. Not coughing it up do I need more meds?

Sinus disease: The sinuses are aerated chambers that often get closed off and infected. Antibiotics are helpful but the important thing is to open them up again so they will drain. This is often achieved by using gentle saline solution or inhaled nasal steroids. Make sure the air you are breathing is not too dry. Occasionally topical antibiotics will help with the healing. ...Read more
