Pharmacist tips for Granisetron

pharmacist

  • Take granisetron tablets 1 hour before receiving chemotherapy or radiation on the day of treatment. If you're taking two separate doses, take the first dose 1 hour before chemotherapy and the second dose 12 hours later.

    • You will usually have to take multiple medications that work together to prevent nausea and vomiting from cancer treatment. Make sure you take your antiemetics correctly and ask your provider if you have questions about your regimen.

      • Let your provider know if you have a history of heart problems, or if you take medications that can affect the way your heart beats. Sometimes, granisetron can lead to heart-related problems when taken with certain other medications.

        • Let your healthcare team know if you've ever had an allergic reaction to an antiemetic before. They might want to monitor you closely for a reaction.

          Frequently asked questions about Granisetron

          Is granisetron the same as ondansetron (Zofran)?
          Granisetron and ondansetron (Zofran) both work on serotonin receptors to prevent nausea and vomiting. They are used for different conditions and have different prices. Sometimes, one might work better than the other for certain people. Both medications come in many different forms; see below for a side-by-side comparison.
          Is granisetron discontinued?
          The brand-name product Kytril has been discontinued, but the generic product is available. It's not clear why the manufacturer (Roche) decided to stop making the brand medication, but the FDA reports that it wasn't for safety reasons.
          Is granisetron safe in pregnancy?
          It's not known if granisetron can harm your unborn baby. Talk to your provider if you're pregnant or have plans on becoming pregnant.
          Should I take granisetron with food?
          Granisetron can be taken with or without food. It's important to remember that this medication is taken about an hour before chemotherapy or radiation. Talk to your care team about good dietary options on treatment days.

          What are the risks and warnings for Granisetron?

          Granisetron can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

          risk-warning

          Serotonin syndrome

          • Risk factors: Taking other medications that can affect the serotonin levels in your brain

            Serotonin syndrome is a rare, but potentially life-threatening condition where there's too much serotonin active in the brain. Your risk goes up if you use granisetron with other medications that affect serotonin levels, such as antidepressants (e.g., escitalopram (Lexapro)), lithium, tramadol (Ultram), sumatriptan (Imitrex), and St. John's Wort. Symptoms of too much serotonin include a fast heart rate, sweating, muscle stiffness or spasms, fever, and confusion. Tell your provider right away if you have any of these symptoms.

            risk-warning

            Heart rhythm problems

            • Risk factors: History of heart rhythm | Taking other medications causing heart rhythm problems

              People taking antiemetics like granisetron can have changes with their heart rhythm. It's more likely to happen in people with a history of heart problems or take other medications that can affect their heartbeat. Make sure your healthcare team knows your medical history and a full list of your medications.

              risk-warning

              Digestion problems

              • Risk factors: Stomach surgery | Taking opioid medications

                There have been reports of severe constipation in people taking granisetron. It can also mask symptoms of intestinal (gut) blockage or bloating. Pay attention to how often you're having bowel movements, and contact your provider if you have constipation, problems passing gas, and pain or swelling in your stomach area.
