Step 1
Talk to your doctor. Antibiotics are only available through prescription for a licensed physician. Explain your symptoms of sinusitis and allow your doctor to examine your nasal and sinus passages. Your doctor may prescribe an antibiotic based on your symptoms or he may take a fluid sample to start a bacterial culture. A bacterial culture will allow the particular bacteria causing your sinusitis to be identified. This makes it much easier to choose which type of antibiotic would be best suited to treat the infection.

Step 2
Inform your doctor of any drug allergies you may have. You should also disclose all prescription and over-the-counter medication you are taking. Chronic conditions should be discussed too. This will help your doctor avoid prescribing medication that may cause an allergic reaction, interact with other drugs or adversely affect your other health conditions.
-
Step 3
Follow both your doctor's directions and the manufacturer's directions. Keep the prescription antibiotics away from excessive light and moisture. You will start see an improvement in your sinus infection symptoms after a few days on prescription antibiotics, but continue to take the prescription until it is gone.

Step 4
Take your prescription antibiotics at regular time intervals to keep a constant level of medicine in your body. If you miss a dose, take it as soon as you notice unless your next dose is within the hour. In that case, just take the next dose.
-
Step 5
Monitor your side effects of the prescription antibiotics and discuss them with your doctor. If any of them increase over time or become unbearable, contact your doctor about discontinuing or changing your prescription. If your face, tongue or throat starts to swell or you have trouble breathing, you could be having an allergic reaction to the prescription medication. Seek emergency medical help immediately.
