Drug Interactions With Aztreonam for Inhalation Solution
A few medications can lead to drug interactions when combined with aztreonam for inhalation solution. These products include Prepopik, Tice BCG, and the typhoid vaccine. The effectiveness of these medications can be decreased if used with aztreonam inhalation solution, so let your healthcare provider know about any other medications, vitamins, and supplements you are taking to avoid complications.
Aztreonam for inhalation solution (Cayston®) may react with a few other medications. Some of the drugs that may interact with aztreonam for inhalation solution include but are not limited to:
- Sodium picosulfate/magnesium oxide/anhydrous citric acid (Prepopik®)
- Tice® BCG (bacillus calmette-guerin)
- Typhoid vaccine.
The following sections explain in detail the potentially negative interactions that can occur when aztreonam for inhalation solution is combined with any of the drugs listed above.
Sodium Picosulfate/Magnesium Oxide/Anhydrous Citric Acid
Sodium picosulfate/magnesium oxide/anhydrous citric acid is a medicine used to empty the bowels before a colonoscopy (this is known as bowel prep). The manufacturer of the medicine recommends that it not be used in combination with antibiotics, as antibiotics may decrease its effectiveness.
Talk to your healthcare provider about this potential interaction before using these drugs together. Although the interaction is likely less of a concern with aztreonam for inhalation solution, as it is inhaled into the lungs and not taken by mouth, your healthcare provider may still choose to give you a different bowel prep medication while you are using aztreonam for inhalation solution.
Tice BCG is a medication used to treat and prevent certain types of bladder cancer. The manufacturer recommends that it not be used in combination with antibiotics, as antibiotics may decrease its effectiveness.
This interaction is likely less of a concern with aztreonam for inhalation solution, as this medicine is inhaled into the lungs and not taken by mouth. However, you should still talk to your healthcare provider about this potential interaction if you are being treated with both of these medications.
Antibiotic medicines, such as aztreonam for inhalation solution, have the potential to decrease the effectiveness of the typhoid vaccine. This interaction is only a concern with the live vaccine, which is taken by mouth. Talk to your healthcare provider about this potential drug interaction before receiving the live typhoid vaccine.
