Most sinus infections are caused by viruses and clear up on their own within 7 to 10 days. What you do during that window makes a real difference in how miserable you feel. The priority is managing pain and congestion at home while watching for signs that the infection has turned bacterial and needs antibiotics.
Figure Out What You’re Dealing With
The vast majority of sinus infections start as viral infections, the same kind of virus behind a common cold. They cause facial pressure, congestion, thick nasal discharge, and sometimes a low-grade fever. These infections don’t respond to antibiotics and simply need time to resolve.
A bacterial sinus infection is less common but requires different treatment. Three patterns suggest bacteria are involved rather than a virus:
- Symptoms lasting 10 days or more without any improvement
- High fever (102°F or higher) combined with facial pain and thick, colored nasal discharge lasting 3 to 4 days
- “Double worsening” where symptoms start to improve after 4 to 7 days, then suddenly get worse again
If any of those patterns match what you’re experiencing, it’s worth calling your doctor. Otherwise, home care is your best option.
Flush Your Sinuses With Saline
Rinsing your nasal passages with salt water is one of the most effective things you can do. It physically washes out mucus, reduces swelling, and helps your sinuses drain. You can use a neti pot, squeeze bottle, or bulb syringe.
To make your own rinse, mix 1 teaspoon of non-iodized salt (canning or pickling salt works well) and a pinch of baking soda into 2 cups of warm water. The water must be distilled, filtered, or previously boiled. Tap water can contain tiny organisms that are harmless to drink but dangerous when introduced directly into your sinuses. After each use, clean your rinse device with the same type of safe water and let it air dry completely.
If you’re also using a medicated nasal spray, do the saline rinse first. This clears the passages so the spray can actually reach the tissue it needs to.
Manage Pain and Pressure
Sinus pressure can be genuinely painful, especially around the forehead, cheeks, and behind the eyes. Over-the-counter pain relievers like ibuprofen or acetaminophen work well for this. Ibuprofen has the added benefit of reducing inflammation in the sinus tissue itself.
A warm compress across your face can also help. Drape a warm, damp towel over your nose and cheeks for a few minutes at a time. It won’t speed recovery, but it loosens congestion and soothes the aching pressure.
Use Decongestant Sprays Carefully
Nasal decongestant sprays like oxymetazoline provide fast, dramatic relief from congestion. They shrink swollen tissue in minutes. But they come with a strict time limit: no more than three days of use. After about three days, the spray starts causing rebound congestion, a condition called rhinitis medicamentosa where your nose becomes more blocked than it was before you started using the spray. You end up needing the spray just to breathe normally, which makes the problem progressively worse.
Oral decongestants (pills or liquids) don’t carry the same rebound risk and can be used somewhat longer, though they can raise blood pressure and cause jitteriness. If you have high blood pressure or heart problems, check with a pharmacist before taking them.
Keep Your Air and Body Hydrated
Thick, sticky mucus is harder for your sinuses to drain. Staying well hydrated helps keep mucus thinner and easier to clear. Water is ideal. Hot drinks like tea or broth also help, partly through hydration and partly because the steam opens nasal passages temporarily.
Indoor air matters too. The EPA recommends keeping humidity between 30 and 50 percent. A cool-mist humidifier in your bedroom can make a noticeable difference, especially in winter when heating systems dry out indoor air. If you don’t have a humidifier, sitting in a steamy bathroom for 10 to 15 minutes works as a short-term substitute. Sleeping with your head slightly elevated also encourages sinus drainage and can reduce that feeling of pressure building overnight.
When Antibiotics Are Needed
If your symptoms match the bacterial patterns described above, your doctor will likely prescribe antibiotics. The standard first choice is amoxicillin, sometimes combined with a second ingredient to cover resistant bacteria. A typical course lasts 7 to 10 days, and most people start feeling noticeably better within the first few days of treatment.
Finishing the full course matters even if you feel better early. Stopping short can allow surviving bacteria to rebound. If your symptoms haven’t improved at all after 3 to 5 days on antibiotics, let your doctor know. You may need a different medication or further evaluation.
Steroid Nasal Sprays for Recurring Problems
Over-the-counter steroid nasal sprays (like fluticasone) work differently from decongestant sprays. They reduce inflammation gradually rather than shrinking tissue instantly, and they’re safe for longer-term use. For a single acute sinus infection, the evidence for steroid sprays is limited. Where they shine is in chronic sinusitis, defined as symptoms persisting beyond 12 weeks, and especially in people who develop nasal polyps. In those cases, steroid sprays significantly reduce symptoms and can cut the risk of polyps returning after surgery by about 40 percent.
If you find yourself getting sinus infections several times a year, a daily steroid spray may be worth discussing with your doctor as a preventive measure rather than a treatment for the current infection.
Symptoms That Need Immediate Attention
Sinus infections rarely become dangerous, but the sinuses sit close to the eyes and brain, so infections can occasionally spread to those areas. Get medical care right away if you develop any of the following:
- Swelling or redness around the eyes
- Vision changes or double vision
- Severe headache, especially with forehead swelling
- A stiff neck
- Confusion or disorientation
- High fever that isn’t responding to medication
These symptoms can signal that the infection has spread beyond the sinuses and may require urgent treatment. They’re uncommon, but recognizing them quickly matters.
What Recovery Actually Looks Like
With a viral sinus infection, expect to feel worst around days 3 through 5, then gradually improve. By day 7 to 10, most people are largely back to normal, though some residual congestion can linger for another week. If you’re on antibiotics for a bacterial infection, improvement usually begins within 48 to 72 hours of starting the medication, with full recovery by the end of the course.
During recovery, colored mucus (green or yellow) is normal and doesn’t automatically mean you have a bacterial infection. The color comes from white blood cells fighting the infection, which happens with both viral and bacterial causes. What matters more than color is the overall pattern: whether symptoms are improving, staying flat, or getting worse over time.
