Symptom relief
Taking either a nonprescription (over-the-counter) or prescription decongestant may help reduce the swelling in your nasal passages and encourage sinus drainage. Decongestants are available in sprays, drops, and tablets.

If your sinusitis is painful, your health care provider may suggest that you take a pain reliever as well. Over-the-counter (nonprescription) painkillers such as aspirin and acetaminophen (Tylenol) can help ease the discomfort of sinusitis.

Having one or more allergies can make sinusitis worse. Taking an antihistamine may bring some relief.

Corticosteroid drugs, which require a prescription, can reduce inflammation. They are available as either pills or a nasal spray.

Antibiotic treatment
If the sinusitis appears to be due to  bacterial infection, the health care provider is likely to prescribe an antibiotic medication such as Avelox^® (moxifloxacin hydrochloride) to kill the bacteria. Although bacterial sinusitis often clears up on its own, antibiotics can shorten the time it takes to get better and reduce the risk that the sinusitis will not clear up and lead to complications.

Surgery
Some people have chronic sinusitis that remains bothersome even if they take medication. One way to treat this problem is with surgery to open the blocked sinus passages.

Home remedies
Besides medication or any other treatment that your health care provider may prescribe, there are some simple things you can do. You won't make the sinusitis disappear, but you may feel better.

• Inhale steam to help soothe inflamed sinus cavities and open obstructed nasal passageways, relieving the pressure inside.
• Rinse a washcloth or small towel in warm water, wring it out, and apply over the inflamed area to help relieve the pain.
• Use a saline (salt and water) nasal spray or drops to relieve some symptoms.
• Drink a lot of water or other fluids to help dilute the secretions and at least partially relieve the congestion.
• Avoid leaning over with your head facing down. That position can increase the pressure on the sinuses and the pain.
• Try to stay inside, where the temperature doesn't change. Sudden temperature changes can make inflammation worse.
