What to Do When You Have a Sinus Infection

Most sinus infections are viral and will clear up on their own within 7 to 10 days with the right home care. Your main job is to manage symptoms, keep your sinuses draining, and watch for the specific signs that mean you need antibiotics or medical attention. Here’s exactly what to do.

Figure Out What You’re Dealing With

Sinus infections cause cloudy or colored nasal drainage, congestion, and pain or pressure around the eyes, forehead, or cheeks. These symptoms lasting up to four weeks count as acute sinusitis, and the vast majority of cases in that window are caused by a virus, not bacteria. That distinction matters because antibiotics only work on bacterial infections.

Three patterns suggest a bacterial infection rather than a viral one:

  • Persistent symptoms: No improvement at all after 10 days.
  • Severe onset: A fever of 102°F or higher with thick, discolored nasal discharge or significant facial pain lasting three or more days from the start.
  • Double worsening: You start to feel better after five or six days, then symptoms suddenly get worse again (new fever, increased pain, more discharge).

If none of those apply, you’re almost certainly fighting a virus, and the steps below are your treatment plan.

Start Nasal Saline Rinses

Nasal irrigation is one of the most effective things you can do. Flushing warm salt water through your nasal passages physically clears out mucus, reduces swelling, and helps your sinuses drain. Daily rinsing with a 2 percent saline solution (salt water buffered with a pinch of baking soda) significantly improves symptoms in people with frequent sinus infections.

You can use a squeeze bottle, neti pot, or nasal rinse cup. The technique is simple: lean over a sink, tilt your head to one side, and gently pour or squeeze the solution into your upper nostril. It flows through your nasal passages and drains out the other side. Repeat on the opposite side. Do this once or twice a day while you’re symptomatic.

One critical safety rule: never use plain tap water. Unsterilized tap water can contain organisms that are harmless if swallowed but dangerous when introduced directly into your nasal passages. The CDC recommends using store-bought water labeled “distilled” or “sterile.” You can also boil tap water at a rolling boil for one minute (three minutes above 6,500 feet elevation), then let it cool before use. Store any leftover boiled water in a clean, covered container.

Manage Pain and Congestion

Over-the-counter medications won’t shorten your infection, but they can make you significantly more comfortable while your body fights it off.

For the pressure and pain, acetaminophen or ibuprofen both work well. Choose whichever you typically tolerate better. These also help bring down any fever.

For congestion, oral decongestants narrow the swollen blood vessels in your nasal passages, which opens things up and helps drainage. Nasal decongestant sprays work faster but carry an important limitation: using them for more than three consecutive days can cause rebound congestion, where your stuffiness actually gets worse when you stop. Oral decongestants don’t have that rebound effect, but they can raise blood pressure and cause jitteriness, so they’re not ideal for everyone.

Use Steam, Fluids, and Sleep Position

Warm, moist air loosens thick mucus and soothes irritated tissue. A hot shower works well, or you can drape a towel over your head and breathe the steam from a bowl of hot water for five to ten minutes. Some people repeat this two or three times a day and find it noticeably easier to breathe afterward.

Staying well-hydrated keeps your mucus thinner and easier to drain. Water and warm liquids like tea or broth are ideal. Alcohol and caffeine can be mildly dehydrating, so they’re not the best choices when you’re congested.

At night, sleep with your head slightly elevated. Propping yourself up on an extra pillow or placing a wedge under the head of your mattress helps mucus drain forward rather than pooling at the back of your throat. This reduces that miserable post-nasal drip cough that tends to get worse when you lie flat, and it can make the difference between a rough night and a tolerable one.

Know When to Call Your Doctor

If you’ve been doing all of the above for 10 days and your symptoms haven’t improved, it’s reasonable to call your doctor and ask about antibiotics. At that point, a bacterial infection is more likely, and a short course of antibiotics may help. Most doctors follow a “watch and wait” approach before prescribing because giving antibiotics for a viral infection doesn’t help and contributes to antibiotic resistance.

If you experience the “double worsening” pattern (improving, then suddenly getting worse around day five or six), that’s also worth a call. Your doctor may want to start antibiotics sooner in that scenario.

Recognize Emergency Warning Signs

Sinus infections rarely become dangerous, but the sinuses sit close to the eyes and brain, so infection can occasionally spread to those areas. Get medical attention immediately if you develop any of the following:

  • Swelling, redness, or pain around your eyes
  • Double vision or other vision changes
  • High fever that isn’t responding to medication
  • Confusion or difficulty thinking clearly
  • A stiff neck

These symptoms suggest the infection may have spread beyond the sinuses and require urgent treatment.

What About Recurring Sinus Infections?

If you get sinus infections several times a year, daily saline rinses (even when you’re feeling fine) can help prevent flare-ups. Some people also benefit from herbal preparations. A European plant-based formula called Sinupret, which combines several herbs, has strong clinical evidence for reducing symptoms of acute sinus infections. Pelargonium sidoides, a South African geranium extract sold in many pharmacies, has moderate evidence for uncomplicated bacterial sinus infections. Bromelain, an enzyme from pineapple, has some support for reducing sinus inflammation, though the evidence is weaker in adults than in children.

Chronic sinusitis, where symptoms persist for 12 weeks or longer, is a different condition with different causes. It often involves ongoing inflammation rather than active infection, and it typically needs evaluation by a specialist to sort out contributing factors like allergies, nasal polyps, or structural issues.
