CONTRAINDICATIONS AND CAUTIONS
- Contraindicated in patients with a history of hypersensitivity to sulopenem, probenecid, or other beta-lactams.

- Use isn't recommended in patients with creatinine clearance less than 15 mL/minute.
- This drug may cause Clostridioides difficile-associated diarrhea, ranging in severity from mild diarrhea to fatal colitis, which may occur more than 2 months after administration. If c. difficile-associated diarrhea is suspected or confirmed, the drug may need to be discontinued, and appropriate treatment begun.
