Antibiotic Use
Antibiotics and sinusitis
Sinuses are hollow spaces in your skull around the eyes and nose. Sinusitis happens when the lining inside the nose and sinuses gets irritated and swells, causing you to have a stuffy or blocked nose, or drainage from the nose or back of the throat. Sinusitis can occur when the fluid is trapped, which can allow germs to grow, sometimes leading to a sinus infection.
Most sinus infections are caused by viruses, so antibiotics won’t help you feel better any sooner, because antibiotics kill bacteria, not viruses. But sometimes a bacterial infection can cause sinusitis. Unfortunately, it is difficult to tell at first whether the sinusitis is caused by a bacteria that needs antibiotics, but luckily only about 1 out of 10 cases of sinusitis is caused by bacteria.
When we use antibiotics when they are not needed, they may not work when we do need them. This is because each time you take antibiotics, you are more likely to have some bacteria that survive and aren't killed by the medicine. Bacteria that don't die can change and become even harder to kill, making your next infection harder to treat. These tougher bacteria can also spread to family members, children, and coworkers. While there are other antibiotics that can be used, these antibiotics often don’t work as well and usually cost more. Also, antibiotics can cause allergic reactions, diarrhea, and other side effects – so it’s best only to use them when you really need them.
If you have a viral sinus infection, ask your pharmacist about over-the-counter medicine for your symptoms, such as congestion, cough, and headache.
Be sure to tell the pharmacist about any prescription medicines that you’re already taking or any medical conditions. Be careful when you use certain nasal drops, which can make your symptoms worse when you stop taking them, if you take them longer than directed.
