What is the most important information I should know about aztreonam (Cayston)?
You should not use this medication if you are allergic to aztreonam.
Before using aztreonam, tell your doctor if you are allergic to any type of antibiotic, especially a cephalosporin (Ceftin, Cefzil, Keflex, Omnicef, and others), a penicillin (Amoxil, Augmentin, Bactocill, Bicillin C-R, Dycill, Dynapen, Omnipen, Principen, PC Pen VK, Pen-V, Pfizerpen, and others), or similar antibiotics such as Invanz, Primaxin, or Marum.
Use aztreonam for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Aztreonam will not treat a viral infection such as the common cold or flu.
If you use other inhaled medications, you may need to use them in a certain order while using aztreonam inhalation. Ask your doctor for specific instructions about when to use your other medications in relation to your aztreonam inhalation doses.
