No significant drug interactions have been identified.

Not all drug interactions are known or reported and new drug interactions are continually being reported.
- It is common to feel better early in the course of therapy, but you should take all of your medication as prescribed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by Cayston or other antibacterial drugs in the future.
- Diarrhea is a common problem caused by antibiotics. This should stop once the antibiotic is discontinued. Sometimes after starting treatment with antibiotics, watery and bloody stools (with or without stomach cramps and fever) can occur even as late as 2 or more months after having taken the last dose of the antibiotic. If this occurs, contact your doctor as soon as possible.
- Severe allergic reactions. Stop your treatment with Cayston and call your doctor right away if you have any symptoms of an allergic reaction, including:
- Rash or swelling of your face
- Throat tightness
- Trouble breathing right after treatment with Cayston (bronchospasm). To decrease the chance of this happening, be sure to use your inhaled bronchodilator medicine before each treatment with Cayston.
- Do not take Cayston if you are allergic to it or to any of its inactive ingredients.
- Tell your doctor if you are allergic to any other medications, especially antibiotics, before taking Cayston. There might be a small risk taking Cayston if you have had an allergic reaction to particularly an antibiotic in the past.
