Most sinus infections are viral and clear up on their own within 7 to 10 days, so the best things you can take are over-the-counter remedies that manage your symptoms while your body fights off the infection. Antibiotics only help when the infection is bacterial, which is less common than most people assume. Here’s what actually works, what doesn’t, and when you need something stronger.
Pain Relievers for Sinus Pressure
The throbbing pressure across your forehead, cheeks, and behind your eyes is often the worst part of a sinus infection. Standard over-the-counter pain relievers handle this well. Ibuprofen has a slight edge because it reduces both pain and the inflammation causing the pressure. Acetaminophen works for pain but won’t do much for swelling. You can alternate between the two, or use a combination tablet that contains both. Stay under 4,000 milligrams of acetaminophen in a 24-hour period to protect your liver.
Decongestants That Actually Work
Not all decongestants are equally effective, and this is a point worth paying attention to. Phenylephrine, the decongestant found in most cold medicines on store shelves, is essentially useless. In 2023, an FDA advisory committee concluded that current data does not support its effectiveness as a nasal decongestant. The problem is biological: your gut breaks down about 97% of a phenylephrine dose before it ever reaches your bloodstream.
Pseudoephedrine, on the other hand, reaches the bloodstream almost completely intact and has real evidence behind it. It’s kept behind the pharmacy counter (you’ll need to show ID to buy it), but it doesn’t require a prescription. Look for it by name on the box, or ask your pharmacist directly. It works by narrowing swollen blood vessels in your nasal passages, which opens up airflow.
If you have high blood pressure, skip oral decongestants entirely. That same blood vessel narrowing effect raises blood pressure throughout your body. This is especially important if your blood pressure is severe or uncontrolled.
Decongestant Nasal Sprays
Sprays like oxymetazoline provide fast, powerful relief, but limit use to three days. Beyond that, your nasal passages can become dependent on the spray and swell up worse than before whenever you stop, a cycle called rebound congestion.
Nasal Steroid Sprays
Over-the-counter nasal corticosteroid sprays reduce swelling and mucus production inside the nasal passages. Unlike decongestant sprays, these are safe for longer use and don’t cause rebound congestion. The tradeoff is patience: they can take up to two weeks of daily use before you feel the full benefit. They work best when used consistently on a daily schedule rather than as needed. If you’re dealing with a sinus infection that’s dragging on, starting one early gives it time to build up its effect.
Saline Rinses
Flushing your sinuses with saltwater using a neti pot or squeeze bottle physically washes out mucus, allergens, and irritants. It’s one of the most effective home remedies for sinus congestion, and it’s drug-free, so you can use it alongside anything else you’re taking.
One safety rule is non-negotiable: never use plain tap water. Tap water can contain bacteria and amoebas that are harmless when swallowed (your stomach acid kills them) but can cause serious, even fatal infections when introduced directly into your nasal passages. Use distilled or sterile water from the store, water that’s been boiled for 3 to 5 minutes and cooled to lukewarm, or water filtered through a device specifically designed to trap infectious organisms. If you boil water ahead of time, use it within 24 hours and store it in a clean, sealed container.
Home Measures That Help
Staying well hydrated thins out mucus, making it easier to drain. Water, tea, and broth all count. A humidifier set to 40% to 50% humidity can also help break up mucus and relieve a stuffy nose, particularly at night when lying flat makes congestion worse. Warm compresses placed across your nose and forehead can ease pressure temporarily. Sleeping with your head slightly elevated encourages sinus drainage and may help you rest more comfortably.
When You Need Antibiotics
Antibiotics do nothing against a virus, and roughly 90% of sinus infections start as viral. A bacterial sinus infection is likely if any of these patterns apply:
- Persistent symptoms: congestion, facial pain, and discharge lasting 10 days or more with no improvement
- Severe onset: a fever of 102°F or higher with facial pain and colored nasal discharge lasting 3 to 4 days
- Double worsening: symptoms that start to improve after 4 to 7 days, then suddenly get worse again
If your doctor determines you have a bacterial infection, the standard first-line treatment is amoxicillin, sometimes combined with clavulanate, prescribed for 5 to 10 days. If you’re allergic to penicillin, doxycycline is a common alternative. Finish the full course even if you feel better after a few days.
Symptoms That Need Immediate Attention
A sinus infection rarely becomes dangerous, but the sinuses sit close to the brain and eyes, so complications can be serious when they occur. Get to an emergency room if you develop a fever over 103°F, vision changes or swelling around your eyes, confusion, a stiff neck, or seizures. These can signal that the infection has spread beyond the sinuses and needs urgent treatment.
Putting a Treatment Plan Together
For most sinus infections, a practical approach combines several of these remedies at once. A typical day might look like ibuprofen for pain and pressure, pseudoephedrine to open up your nasal passages, a saline rinse once or twice, and a humidifier running while you sleep. If you’re already using a nasal steroid spray for allergies, keep using it. If you aren’t, starting one can help with the swelling, though it won’t kick in right away.
Give your body 7 to 10 days. If symptoms plateau or fit one of the bacterial patterns described above, that’s when it makes sense to see a provider and discuss antibiotics. Most people recover fully without them.
