### Why Antibiotics Might Not Always Be the Best Treatment for Sinus Infections Many people with sinus problems often ask their doctors for antibiotics. However, research shows that about 83% of adults in the U.S. who see a doctor for acute sinusitis get an antibiotic, even though most don't need it. Acute sinusitis lasts less than 4 weeks, while chronic sinusitis lasts longer than 12 weeks. Sinus infections are usually caused by viruses or bacteria, leading to thick mucus and discomfort. Antibiotics may not always be the best remedy for sinusitis. Your body can often cure mild or moderate sinusitis on its own, and overusing antibiotics can lead to antibiotic resistance. Medical guidelines recommend cautious use of antibiotics. Studies show that 60%-70% of people with sinus infections recover without antibiotics. In one study, patients given antibiotics did no better than those not given antibiotics. Doctors may not always know if sinusitis is bacterial or viral because diagnosis is usually based on symptoms. Symptoms include thick mucus, facial pain, and congestion. Sometimes, other tests like CT scans are used for diagnosis. Some doctors suggest waiting 3-5 days before filling an antibiotic prescription to see if symptoms improve on their own. Only about 2% of sinus infections are caused by bacteria. Antibiotics are usually prescribed if symptoms persist or worsen. Common antibiotics include amoxicillin and doxycycline. However, overuse of antibiotics like azithromycin has led to drug resistance. If you're pregnant, some antibiotics are safer than others. Penicillin and cephalosporin are generally safe, while tetracyclines and fluoroquinolones should be avoided. If symptoms don't improve after 7-10 days on antibiotics, you may have a viral infection or a more serious issue like a nasal blockage. Over-the-counter medications can help with symptoms, and rest and fluids are also beneficial. Most sinus infections go away within 2 weeks without antibiotics. Factors like cigarette smoke, dry air, and pollutants can worsen sinusitis.
