How long before chemotherapy should the Sancuso patch be applied for effectiveness?

The Sancuso patch is designed to prevent nausea and vomiting associated with chemotherapy by delivering the active ingredient granisetron transdermally. For optimal effectiveness, the patch should be applied 24 to 48 hours prior to the administration of chemotherapy. This timeframe allows the medication to be adequately absorbed into the bloodstream, ensuring that the levels of the drug are sufficient to counteract potential nausea and vomiting caused by the chemotherapy regimen.

Applying the patch too close to the chemotherapy treatment, such as only a few hours beforehand, may not provide enough time for the medication to reach therapeutic levels in the body, which could lead to inadequate control of symptoms. Therefore, the recommendation to apply it 24 to 48 hours before chemotherapy is crucial for maximizing its effectiveness in managing nausea and improving patients' overall comfort during their treatment.
