Aztreonam for Inhalation Solution Dosage

People who use aztreonam for inhalation solution all receive the same dosing guidelines, which call for inhaling this medicine three times daily. This antibiotic is used for 28 days, followed by a 28-day break before resuming treatment. Your healthcare provider will tell you how many treatment cycles you need.

An Introduction to Your Dosage of Aztreonam for Inhalation Solution

There is only one standard recommended dose of aztreonam for inhalation solution (Cayston®), regardless of your age or weight. As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.

Recommended Aztreonam for Inhalation Solution Dosing Guidelines

The usual recommended dosage of aztreonam for inhalation solution is one single-use vial (75 mg) mixed with one 1-mL ampule of saline three times a day. The medication is normally taken for 28 days, followed by a 28-day break when no aztreonam for inhalation solution is used. This cycle of 28 days using the drug followed by 28 days off should be repeated until your healthcare provider tells you otherwise.
Aztreonam for inhalation solution is inhaled using a nebulizer. A nebulizer is a machine that takes a small amount of liquid and turns it into a fine mist that can be inhaled into the lungs. This medicine must be diluted with 1 mL of sterile diluent (saline) immediately prior to pouring it into the nebulizer. You will receive the saline in single-use ampules along with your medicine.
It is recommended that a bronchodilator be used before each aztreonam for inhalation solution dose. Bronchodilators are inhaled medicines that help open up the airways. If you are using a short-acting bronchodilator, it should be used between 15 minutes and 4 hours before aztreonam for inhalation solution. Long-acting bronchodilators can be taken between 30 minutes and 12 hours before using aztreonam for inhalation solution.
If you are taking other medicines or treatments to help with your cystic fibrosis, it is recommended that you take them in this order:
  • Bronchodilators first
  • Medicines that help clear mucus from your lungs (mucolytics) next
  • Aztreonam for inhalation solution last.
