- Apply granisetron 24 to 48 hours before your chemotherapy treatment, or as directed by your doctor.
- Granisetron should be applied to clean, healthy skin on the upper arm. Do not apply to cut, scraped, or irritated skin. Do not use creams, oils, lotions, powders, or any other products that could irritate the skin or prevent the patch from sticking well.
- To apply granisetron, remove the patch from the sealed pouch. Do not cut or damage the patch. Remove the thin, clear, protective liner. Bend the patch in the middle and remove one-half of the rigid plastic film. Apply the exposed, sticky area of the patch to your skin. Remove the other half of the rigid plastic film and press the whole patch firmly in place against the skin.
- If the patch does not stick well, you may tape the edges with surgical bandages or medical adhesive tape. Do not completely cover the patch with bandages or tape. Do not wrap completely around your arm. Ask your health care provider if you are unsure of what type of dressing you can use.
- Wash your hands immediately after using granisetron.
- You may shower or bathe normally while wearing the patch. You should avoid activities such as swimming, strenuous exercise, or using a sauna or whirlpool. It is unknown how these activities may affect granisetron.
- Continue to wear the patch during your chemotherapy and for at least 24 hours after your treatment is completed. Granisetron may be worn for up to 7 days or as directed by your doctor.
- To remove the patch, gently peel it off of your skin and fold the sticky side together. Throw the used patch in the trash away from children and pets. Wash your hands after handling the patch.
- Gently wash the skin with soap and water where the patch was applied.
- If you miss a dose of granisetron, contact your doctor immediately.
Ask your health care provider any questions you may have about how to use granisetron.

- Do not expose granisetron to the sun, sunlamps, or tanning booths while you wear it. It might not work as well and could cause skin irritation. Keep the patch covered with clothing if you will be in sunlight or near a sunlamp or tanning bed. You will also need to cover the skin where the patch was applied for an additional 10 days after you remove the patch to protect it from exposure to direct sunlight.
- Tell your doctor right away if you experience skin irritation (eg, bumps, blisters, itching, redness, or rash) at the application site or on other areas of the body.
- Serotonin syndrome is a possibly fatal syndrome that can be caused by granisetron. Your risk may be greater if you take granisetron with certain other medicines (eg, certain medicines used to treat depression, pain, migraines). Symptoms may include agitation; confusion; hallucinations; coma; fever; fast or irregular heartbeat; tremor; excessive sweating; and nausea, vomiting, or diarrhea. Contact your doctor at once if you have any of these symptoms.
- Granisetron should be used with extreme caution in CHILDREN; safety and effectiveness in children have not been confirmed.
