What to Do for a Sinus Infection: Relief and Red Flags

Most sinus infections are caused by viruses, not bacteria, and they clear up on their own within 7 to 10 days. Only about 0.5 to 2 percent of cases involve a bacterial infection. That means the best thing you can do for a typical sinus infection is manage your symptoms at home while your body fights it off. Here’s how to do that effectively, and how to know when you need more help.

Why Most Sinus Infections Don’t Need Antibiotics

Because viruses cause the vast majority of sinus infections, antibiotics won’t help in most cases. Even when bacteria are involved, the infection is often self-limited. Most adults feel well or nearly well after 7 to 10 days, though about 25 percent still have some symptoms at the two-week mark.

Current guidelines from the American Academy of Otolaryngology (updated in 2025) recommend a “watchful waiting” approach for otherwise healthy adults suspected of having a bacterial sinus infection. This means managing symptoms for several days before considering antibiotics. Your doctor may suggest this observation period lasts three to five days or longer, depending on how you’re doing. If your symptoms haven’t improved after that window, antibiotics become a reasonable option.

Clearing Congestion Safely

Congestion is usually the most miserable part of a sinus infection, and there are a few ways to tackle it. Nasal saline rinses (using a neti pot or squeeze bottle) physically flush mucus and irritants out of your sinuses. They’re one of the most consistently helpful things you can do. The key safety rule: never use plain tap water. Use store-bought distilled or sterilized water, or boil tap water at a rolling boil for one minute and let it cool before use. This prevents rare but serious infections from waterborne organisms.

Over-the-counter decongestant sprays can open your nasal passages quickly, but limit use to three days. Beyond that, they can cause rebound congestion, a condition called rhinitis medicamentosa, where your nose becomes more blocked than it was before you started using the spray. Oral decongestants are another option and don’t carry the same rebound risk, though they can raise blood pressure and cause jitteriness.

Steroid nasal sprays (like fluticasone, available over the counter) reduce inflammation in the sinus lining. A review of clinical trials found that people using these sprays were more likely to see their symptoms resolve compared to those using a placebo, with about 73 percent improving versus 66 percent. The benefit is modest but real, and these sprays are safe to use for longer stretches than decongestant sprays.

Managing Pain and Pressure

Facial pressure, headache, and pain around the eyes or forehead are hallmarks of a sinus infection. Over-the-counter pain relievers like ibuprofen and acetaminophen are the most commonly used treatments for this, with roughly 40 to 45 percent of sinus sufferers reaching for them regularly. Ibuprofen has the added benefit of reducing inflammation, which can help with swelling in the sinus passages. You can alternate between the two if one alone isn’t enough, since they work through different mechanisms.

Warm compresses placed over your forehead, nose, and cheeks can also ease pressure. Some people find that sleeping with their head slightly elevated helps sinuses drain overnight, reducing that heavy, congested feeling in the morning.

Does Steam Actually Help?

Steam inhalation is one of the most common home remedies people try. A clinical trial tested daily five-minute steam sessions (leaning over a bowl of recently boiled water with a towel draped over the head) and found that steam reduced headache symptoms but had no significant effect on other sinus symptoms like congestion or facial pressure. It’s not harmful, and if the headache relief alone feels worth it to you, there’s no reason not to do it. Just be careful with the hot water to avoid burns.

Signs You Need Medical Attention

A bacterial sinus infection is suspected when symptoms persist at least 10 days without improvement, or when you experience a “double worsening” pattern: you start to feel better, then get noticeably worse again around day five or six. A fever lasting longer than three to four days is another signal that something beyond a simple virus may be going on.

Certain symptoms suggest the infection may be spreading beyond your sinuses and require prompt medical evaluation:

  • Swelling or redness around the eyes, which can indicate the infection has reached the eye socket
  • Double vision or other vision changes
  • Forehead swelling
  • Severe headache that doesn’t respond to pain relievers
  • Stiff neck or confusion, which could signal the infection has spread toward the brain

These complications are rare, but they’re serious. If you notice any of them, get medical care the same day.

When Sinus Problems Keep Coming Back

If you’re dealing with multiple sinus infections per year, or if your symptoms have lingered for 12 weeks or more, you may have crossed from acute into chronic sinusitis. Chronic sinusitis is defined by at least 12 weeks of symptoms that include two or more of the following: thick or discolored nasal drainage, nasal congestion, facial pain or pressure, and a reduced sense of smell.

Chronic sinusitis is a different condition from an occasional sinus infection and typically requires a different treatment approach. Your doctor may recommend imaging of your sinuses, allergy testing, or a referral to an ear, nose, and throat specialist. Long-term management often involves daily nasal saline rinses, steroid nasal sprays used consistently rather than just during flare-ups, and in some cases, treatment for underlying allergies or structural issues in the nose.
