Cayston Drug Interactions
Talk to your healthcare provider about all other vitamins, supplements, and medications you are taking before starting treatment with Cayston. Drug interactions may occur when Cayston is combined with a few products, including Prepopik, Tice BCG, and the typhoid vaccine. Combining these products can make the medications less effective.
Cayston® (aztreonam for inhalation solution) may react with a few other medications. Some of the drugs that may interact with Cayston 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 Cayston 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 Cayston, as it is inhaled into the lungs and not taken by mouth, your healthcare provider may still decide to give you a different bowel prep medication while you are using Cayston.
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 Cayston, as Cayston 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 Cayston, have the potential to decrease the effectiveness of the typhoid vaccine. This interaction is only a potential concern with the live vaccine, which is taken by mouth. Talk to your healthcare provider about this issue before receiving the live typhoid vaccine.
