Having cancer is devastating enough; going through chemo or radiation therapy for treatment of cancer and being nauseous or vomiting adds to the discomfort and unpleasantness of the situation. Your doctor can give you a prescription for Kytril*or generic Granisetron to help prevent the sickness that follows chemotherapy or radiation sessions. The generic alternative is not manufactured by the company that makes the brand product.
Kytril is a serotonin receptor antagonist also known as 5-HT3. When taken as directed, Kytril or generic Granisetron blocks the serotonin receptors located in nerve cells in your gut and brain to stop the nausea messages from being sent to the vomiting center located in your brain. The cancer drugs work to destroy the cancer cells but also kill other cells which alerts your immune system that there is a toxin in your body. The immune response is to cause you to vomit so the poison is expelled from your body.
Your doctor may also prescribe the injectible form of Kytril to prevent vomiting after surgery, usually from the anesthetic. Some surgical procedures performed on your heart or abdomen could be jeopardized if you become sick post-operatively as the strain of vomiting can put stress on your body and the sutures.
Side effects from chemo or radiation therapy can be delayed after initial treatment so you may have to take Kytril for several days after. Illness brought about by anesthetics only last for as long as the medicine is in your body.
Ask your doctor about any risks of taking Kytril while you are pregnant, may become pregnant, or are breast feeding. To determine if Kytril is safe for you, explain other medical conditions or allergies to your doctor and list any OTC or Rx drugs you take or use, including herbal remedies and dietary or vitamin supplements.
Do not stop, start, or change the dosage of any current meds you take without consulting with your doctor as this could interfere with how Kytril will perform for you. Until you know how Kytril will affect you, avoid operating a vehicle, machinery, or performing any task that may be considered unsafe.
