Why is this medication prescribed?

Granisetron transdermal patch is typically prescribed to prevent nausea and vomiting caused by chemotherapy, radiation therapy, or surgery. It belongs to a class of medications called serotonin 5-HT3 receptor antagonists, which work by blocking the action of serotonin, a natural substance in the body that can trigger nausea and vomiting.

How should this medicine be used?

Granisetron transdermal patches are typically used to prevent nausea and vomiting caused by chemotherapy or radiation therapy. Here’s how they are typically used:

• Application: The patch is usually applied to clean, dry skin on the upper outer arm at least one hour before chemotherapy or as directed by your healthcare provider.
• Preparation: Before applying the patch, make sure to wash your hands thoroughly to prevent any contamination. Remove the patch from its packaging and peel off the protective liner to expose the adhesive side.
• Application Site: Choose a flat, hairless area of skin on the upper outer arm. Avoid areas with cuts, irritation, or skin folds. Do not apply the patch to areas where creams, lotions, or oils have been recently applied.
• Application: Press the patch firmly onto the skin and hold it in place for a few seconds to ensure proper adhesion. Smooth out any wrinkles or air bubbles to ensure full contact with the skin.
• Avoiding Water: Try to avoid exposing the patch to water, such as bathing or swimming, as excessive moisture can reduce its effectiveness.
• Patch Removal: The patch is typically worn for up to 7 days, depending on your treatment schedule. After this time, carefully peel off the patch and dispose of it properly. Fold the patch in half with the sticky sides together and discard it in a trash can, away from children and pets.
• Storage: Store the patches at room temperature, away from heat and moisture, and keep them in their original packaging until ready for use.

Always follow the instructions provided by your healthcare provider or pharmacist for the specific dosage and usage of Granisetron transdermal patches. If you have any questions or concerns about how to use the patch, don’t hesitate to ask your healthcare provider for guidance.
