Does Sugammadex Interact with Toremifene?
Sugammadex and Toremifene have a moderate drug interaction according to U.S. FDA drug labeling data. Concomitant use can delay recovery to TOF ratio of 0.9 due to displacement of vecuronium or rocuronium from the sugammadex complex. The mechanism involves high binding affinity of toremifene for sugammadex may displace neuromuscular blocking agents from the complex. Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This information is based on official FDA drug labeling sourced from OpenFDA and the NIH National Library of Medicine.

How This Interaction Works
The interaction between Sugammadex and Toremifene occurs because high binding affinity of toremifene for sugammadex may displace neuromuscular blocking agents from the complex. Clinically, this means concomitant use can delay recovery to tof ratio of 0.9 due to displacement of vecuronium or rocuronium from the sugammadex complex. This is classified as a moderate interaction. While it may not require stopping either medication, your healthcare provider should be aware you are taking both so they can monitor for potential effects and adjust treatment if necessary.
What To Tell Your Doctor or Pharmacist
If you are taking Sugammadex and your doctor is considering prescribing Toremifene (or vice versa), make sure to:
- Inform your doctor and pharmacist of all current medications, including over-the-counter drugs and supplements
- Ask whether the benefits of combining these medications outweigh the risks for your specific situation
- Ask what symptoms to watch for that would indicate the interaction is causing problems
- Ask whether any dosage adjustments are needed
- Never stop or change either medication without first consulting your healthcare provider
