If you've been knocked out by sinus infection symptoms—stuffiness, face pain or pressure, and nasal discharge—your doctor might recommend you wait it out for a week or so before resorting to an antibiotic. 

That's because many health experts, including Zara Patel, M.D., a sinus infection expert and assistant professor of Otolaryngology at Stanford University, are urging doctors to think twice before prescribing antibiotics for sinus and other respiratory infections.

"For acute sinusitis, there are very well done studies indicating that antibiotics are not necessary in the vast majority of patients, and most people will be able to clear an infection on their own," says Patel.

Sinus infections, or sinusitis, usually stem from a viral infection, not a bacterial one—and antibiotics don’t work against viruses. Even when bacteria does cause your sinusitis, it usually clears up on its own without drugs, according to Choosing Wisely treatment guidelines, which were developed with the American Academy of Allergy, Asthma & Immunology (AAAAI). (Consumer Reports is a partner in Choosing Wisely, a program aimed at avoiding wasteful, needless or risky overuse of medications, tests, and procedures.)

In a study of 166 adults with acute sinusitis published in the February 2012 issue of the Journal of the American Medical Association (JAMA), the antibiotic amoxicillin proved no better than a placebo at reducing symptoms after three days.

According to the AAAAI, not only will taking antibiotics not help you feel better, but it might also have unpleasant side effects that could leave you feeling worse.

The AAAAI treatment guidelines suggest nearly 25 percent of people who take antibiotics experience side effects, most commonly, diarrhea, stomach problems, and rashes. Even more concerning is that these drugs also contribute to the spread of resistant superbugs, which sicken at least 2 million people in the U.S. every year. 

Feel Better Sooner Without Antibiotics

Instead of taking antibiotics for sinusitis, Consumer Reports chief medical adviser, Marvin M. Lipman, M.D., recommends you get plenty of rest, rinse your nose with a saltwater sinus rinse or spray, drink warm fluids, and inhale steam from a hot bath, shower, or kettle. For pain, he says, try an over-the-counter pain reliever such as acetaminophen (Tylenol or generic) or ibuprofen (Advil or generic).

If needed, your doctor can prescribe a prescription corticosteroid spray, such as fluticasone or triamcinolone. A systematic review published in JAMA in September 2015 found that after saline irrigation, the second-best treatment for chronic sinusitis was a topical corticosteroid spray for a few days. 

When to Consider Antibiotics for Sinus Infections

AAAI advises that antibiotics for sinus infections should only be considered if you develop a fever of 102 or more; have severe face pain and tenderness; if your symptoms last longer than a week or so; or if your symptoms improve and then worsen again.

Says Patel: "Some patients with acute sinusitis do need antibiotics, and if they continue with a worsening infection without treatment they can suffer dramatic complications such as loss of vision, meningitis, or brain abscess."

If your doctor says you need an antibiotic, ask for generic amoxicillin. It's usually the best choice, costs as little as $4 for a prescription, and works as well as more expensive brand-name antibiotics.

Avoid taking fluoroquinolones, a group of antibiotics that includes ciprofloxacin (Cipro) and levofloxacin (Levaquin). Although widely used, the antibiotics are inappropriate for treating sinus infections and they pose serious risks.

Last year after a safety review, the Food and Drug Administration linked fluoroquinolones to disabling and potentially permanent side effects. The agency advised against using the drugs to treat common illnesses—bronchitis, sinus infections, and urinary tract infections.
