Azithromycin for Sinus Infections Online

Azithromycin is an antibiotic prescribed to treat certain bacterial infections including bronchitis; pneumonia; sexually transmitted diseases (STD); and infections of the ears, lungs, sinuses, skin, throat and reproductive organs.¹

Azithromycin comes as a tablet, an extended-release liquid and a liquid to take by mouth. The tablets and suspension are usually taken with or without food once a day for 1-5 days.

To help you remember to take azithromycin, take it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take azithromycin exactly as directed. Do not take more or less of it, or take it more often than prescribed by your doctor.

If you vomit within an hour after taking azithromycin, call your doctor right away. Your doctor will tell you if you need to take another dose. Do not take another dose unless your doctor tells you to do so.

You should begin to feel better during the first few days of treatment with azithromycin. If your symptoms do not improve, or get worse, call your doctor.

Take azithromycin until you finish the prescription, even if you feel better. Do not stop taking azithromycin unless you experience severe side effects. If you stop taking azithromycin too soon or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics.²

You should begin to feel better during the first few days of treatment with azithromycin. If your symptoms do not improve, or get worse, contact your provider.

Always take azithromycin until you finish the prescription. If you stop too soon, the infection may not be fully treated.³

Azithromycin will stay in your system for approximately 15.5 days after your last dose.⁴ 

Commonly prescribed doses are 500 mg to 2000 mg for the first dose. Depending on the severity and type of infection, the prescription may follow with 250 mg to 500 mg per day for several days.⁵

• Tell your doctor and pharmacist if you are allergic to azithromycin, clarithromycin (Biaxin, in Prevpac), erythromycin (E.E.S., ERYC, Erythrocin), any other medications, or any of the ingredients in azithromycin tablets or suspension (liquid). Ask your pharmacist for a list of the ingredients.

• Tell your doctor and pharmacist what other prescription and nonprescription medications, vitamins, nutritional supplements and herbal products you are taking or plan to take while taking azithromycin. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.

• If you are taking antacids containing aluminum hydroxide or magnesium hydroxide (Maalox, Mylanta, Tums, others), you will need to allow some time to pass between when you take a dose of these antacids and when you take a dose of azithromycin tablets or liquid. Ask your doctor or pharmacist how many hours before or after you take azithromycin you may take these medications. The extended-release suspension may be taken at any time with antacids.

• Tell your doctor if you have ever had jaundice (yellowing of the skin or eyes) or other liver problems while taking azithromycin. Your doctor will probably tell you not to take azithromycin.

• Tell your doctor if you or anyone in your family has or has ever had a prolonged QT interval (a rare heart problem that may cause irregular heartbeat, fainting or sudden death) or a fast, slow or irregular heartbeat, and if you have low levels of magnesium or potassium in your blood; if you have a blood infection; heart failure or other heart problems; cystic fibrosis; myasthenia gravis (a condition of muscles and the nerves that control them); or if you have kidney or liver disease.

• Tell your doctor if you are pregnant, plan to become pregnant or are breastfeeding. If you become pregnant while taking azithromycin, call your doctor.⁷
