Aztreonam is an antibiotic that fights bacteria.

Aztreonam inhalation is used to improve breathing symptoms in people with cystic fibrosis and a lung infection caused by bacteria called Pseudomonas aeruginosa.

This medicine is for use in adults and children at least 7 years old with a 1-second forced expiratory volume (FEV1) between 25% and 75%.

Aztreonam may also be used for purposes not listed in this medication guide.

How should I use aztreonam?

How should I use aztreonam?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Use this medicine only with an Altera brand nebulizer. Do not mix other medicines with aztreonam in the nebulizer.

Be sure you understand how to properly mix this medicine with the liquid (diluent) before pouring it into the nebulizer. Prepare your dose only when you are ready to use the nebulizer. Call your pharmacist if the medicine looks cloudy or has particles in it.

Throw away the medicine ampule (bottle) after one use, even if there is still medicine left inside.

Aztreonam inhalation is usually given 3 times daily at 4-hour intervals for 28 days. Follow your doctor's dosing instructions very carefully.

You may need to use a bronchodilator medicine before each dose of aztreonam. Use only the bronchodilator your doctor has prescribed and carefully follow all instructions about timing the doses in relation to your aztreonam dose.

If you use a short-acting bronchodilator such as albuterol or levalbuterol (Combivent, DuoNeb, ProAir, Proventil, Respimat, Ventolin, Xoponex): Use the bronchodilator between 15 minutes and 4 hours before using aztreonam.

If you use a long-acting bronchodilator such as salmeterol or formoterol (Advair, Breo, Dulera, Foradil, Serevent, Symbicort): Use the bronchodilator between 30 minutes and 12 hours before using aztreonam.

If you use a medicine to clear mucus from your lungs, use it after using a bronchodilator and before using aztreonam.

Keep using aztreonam for the entire 28 days, even if your symptoms quickly improve. Skipping doses could make your infection resistant to medication. Aztreonam will not treat a viral infection (flu or a common cold).

Store the medicine and diluent in the refrigerator. Do not freeze. Do not use past the expiration date on the label.

You may store the medicine and diluent at room temperature for up to 28 days, protected from heat and light. Do not use the medicine if it has been at room temperature for longer than 28 days.
