Get Kytril Online

Kytril (granisetron) is prescribed to prevent nausea and vomiting caused by chemotherapy, radiation therapy, or surgery. It is most commonly used in patients undergoing cancer treatment.

Kytril selectively blocks serotonin 5-HT3 receptors located in the gastrointestinal tract and the brain. By blocking these receptors, it prevents the signals that trigger the vomiting reflex during chemotherapy or radiation.

Kytril is typically taken within one hour before the start of chemotherapy. Your prescribing physician will provide specific dosing instructions based on your treatment schedule.

Common side effects include headache, constipation, fatigue, and diarrhea. Less commonly, Kytril may cause changes in heart rhythm. Contact your doctor if you experience chest palpitations or irregular heartbeat.

Kytril, like other 5-HT3 antagonists, can cause small changes in the heart's electrical activity (QT interval prolongation). Patients with pre-existing heart rhythm disorders or those taking other QT-prolonging medications should discuss this risk with their physician before starting Kytril.

Kytril can interact with other medications, including those that affect heart rhythm and certain serotonergic drugs. Your Doctronic physician will review your full medication list to check for interactions before prescribing.
