A blocked nose, pressure around your cheeks and mucus dripping down your throat can make a sinus infection miserable. Home care can ease some symptoms, but it cannot tell you whether the cause is viral, bacterial or something else. Most sinus infections improve without antibiotics; some need medical treatment.
Seek emergency medical care immediately for swelling around an eye, a change in vision or pain when moving the eye. Seek medical advice for severe symptoms, symptoms that worsen after improving, or more than 10 days without improvement. You do not need to try every home remedy before asking for help.
What a sinus infection feels like
Your sinuses are air-filled spaces around the nose, forehead, cheeks and eyes. When their lining becomes inflamed and drainage is blocked, mucus can build up. Symptoms may include congestion, facial pressure, reduced smell, headache, cough, bad breath and postnasal drip. A cold or allergy can cause similar symptoms, so a stuffy nose alone does not confirm an infection.
Most acute sinus infections are caused by viruses. Bacteria can also cause them. Allergies and smoke exposure can contribute to sinus problems, but irritation is not the same thing as a bacterial infection. For allergy-specific advice, see our pollen allergy guide.
MedlinePlus distinguishes acute from longer-lasting sinusitis. Symptoms continuing for about three months or repeatedly returning need assessment rather than an extended course of home remedies.
When to get medical care
The CDC recommends seeing a healthcare provider for:
- Severe headache or facial pain.
- Symptoms that improve and then get worse again.
- More than 10 days of symptoms without improvement.
- Fever lasting longer than three to four days.
- Several sinus infections within a year.
These are reasons to get assessed, not a home test proving that antibiotics are needed. Contact your care team sooner if you have a weakened immune system or are concerned about how ill you feel.
Eye symptoms need urgent attention
Swelling around an eye, especially with fever, pain on eye movement, double vision or reduced vision can signal a serious complication. Orbital cellulitis is a medical emergency, and a sinus infection can be its starting point. Seek emergency medical care immediately rather than massaging the area or waiting for a rinse to help.
If you develop headache, fever, confusion or vomiting after nasal rinsing, seek medical attention immediately and tell the clinician about the rinse and the water used. This is the CDC’s specific warning about illness after nasal rinsing.
Practical ways to feel more comfortable
Try a comfortably warm compress
Rest a clean, warm, damp washcloth gently over your nose and forehead. It may ease pressure. Test the temperature first, keep it comfortably warm rather than hot, and avoid pressing hard or rubbing a painful area. The aim is comfort, not forcing your sinuses to drain.
Use a commercial saline spray
A saline mist can moisten nasal passages and may make congestion easier to manage. Follow the package directions and keep the nozzle clean. A ready-to-use saline spray is different from a medicated decongestant spray and from a refillable irrigation device. Check which one you are buying rather than treating all nasal products as interchangeable.
Drink fluids and make room for rest
Drinking fluids can help keep mucus thinner, and adequate sleep supports recovery. Keep a drink nearby and eat manageable meals. You do not need a rigid eight-glass schedule or a prescribed amount of garlic, ginger or onion to recover. Follow any fluid restriction your clinician has given you.
MedlinePlus adult aftercare advice includes fluids, saline, warm compresses and avoiding smoke. A warm shower may feel soothing, but do not lean over a bowl or pot of boiling water under a towel. Hot water and steam can burn.
Use a humidifier only when the air is dry
More humidity is not always better. If you use a portable humidifier, empty and dry its tank and replace the water daily. Follow the manufacturer’s cleaning instructions; the EPA recommends cleaning portable units every third day. Unplug the device before cleaning.
Keep indoor relative humidity at or below 50%. Lower the output or stop using the unit if windows collect condensation or nearby surfaces become damp. Dirty tanks can spread microorganisms, while excessive moisture encourages mold and dust mites. A humidifier is optional comfort equipment, not an infection treatment.
How to use a nasal rinse safely
Nasal irrigation can help clear mucus. Safe water and a clean device are essential.
Choose the right water
Use water labeled distilled or sterile. Another option is tap water that has been properly boiled and cooled. Current CDC instructions specify a rolling boil for one minute, or three minutes above 6,500 feet, followed by cooling. Store unused boiled water in a clean, sanitized, tightly covered container.
Do not use untreated tap water, and do not assume ordinary bottled drinking water meets the requirement. Adding a salt packet does not make unsafe water safe.
Follow the device instructions
- Wash and dry your hands. Start with a clean, dry device.
- Mix a nasal-irrigation saline packet with the specified amount of safe water. Do not improvise a stronger mixture or add oils.
- Follow the device instructions. For a neti pot, lean over a sink, tilt your head sideways and breathe through your mouth as solution drains through the lower nostril.
- Repeat on the other side as directed, then clean the device and let it dry fully between uses.
The FDA’s nasal-rinsing guidance recommends professional advice if your immune system is weakened. Children need an age-appropriate device and pediatric guidance. Stop rinsing and contact a clinician for nosebleeds or worsening symptoms. New headache, fever, confusion or vomiting after a rinse needs immediate medical attention, as noted above.
Choosing over-the-counter medicines
Ask a pharmacist which product matches the symptom you want to relieve and is suitable for your health conditions, medications and age. Pregnancy, breastfeeding and treatment for a child also warrant specific advice.
Check ingredients before combining products
Acetaminophen or an NSAID such as ibuprofen may help pain or fever when appropriate for you. Follow the Drug Facts label. Combination cold-and-sinus products may already contain a pain reliever, so check active ingredients before adding another medicine.
The FDA warns about duplicate ingredients and excess doses. Acetaminophen can harm the liver when too much is taken; NSAIDs have different risks, including stomach bleeding and kidney problems. Ask before use if you have relevant medical conditions or take other drugs.
Keep medicated nasal sprays short-term
Some decongestant sprays temporarily relieve stuffiness but can make congestion rebound when overused. For example, oxymetazoline should not be used for longer than three days. Follow your particular product’s instructions. This limit does not refer to plain saline spray.
Antihistamines and steroid nasal sprays may be useful when allergies are involved. They do not turn an allergy into an infection or replace an assessment when symptoms are severe. Do not automatically add every available cold remedy to your routine.
When antibiotics may help
Antibiotics do not treat a viral sinus infection. A clinician considers the severity, duration and pattern of symptoms when assessing a possible bacterial cause. CDC adult prescribing guidance supports watchful waiting for appropriate uncomplicated cases when follow-up is available.
If you receive a delayed prescription, make sure you understand when to start it and when to contact the clinician instead. If an antibiotic is prescribed for immediate use, take it exactly as directed. Do not borrow someone else’s medication, use leftovers or choose a treatment length from an online list. Report side effects or worsening illness to your prescriber.
Remedies to skip
Do not swallow eucalyptus oil or apply it to the roof of your mouth. “Food-grade” labeling does not make this a safe sinus remedy. Poison Control warns that swallowing eucalyptus oil can cause serious poisoning. Research involving a specific formulated product is not permission to swallow essential oil from a bottle.
Do not put essential oils, honey or garlic into a nasal rinse. Use a product intended for nasal irrigation according to its directions. If someone swallows eucalyptus oil, contact U.S. Poison Control at 1-800-222-1222 promptly; call 911 for a seizure, trouble breathing or inability to wake the person.
Ordinary foods can be part of your meals, but you do not need to force down garlic or buy “immune-boosting” supplements. Drinking extra water does not flush a sinus virus out of your body. Be wary of anything promising to cure the infection overnight.
A simple plan for the next few days
Write down when symptoms began, whether they improved before getting worse, and any fever readings. List the medicines you take and what you have already tried. These details are more useful at an appointment than simply saying that your sinuses feel blocked.
If home care is appropriate, choose a small number of measures you can manage: rest, fluids, a warm compress and saline if helpful. Follow medicine labels, keep rinse equipment clean and avoid smoke. Check the overall trend each day. Seek care when the warning signs or time thresholds above apply, even if one remedy gives brief relief.
