About this active substance

Ondansetron is a medication used to prevent and treat nausea and vomiting caused by chemotherapy, radiotherapy, or surgery. It belongs to the class of 5-HT3 serotonin receptor antagonists, working by blocking these receptors in the brain and gastrointestinal tract, thereby reducing the reflex of nausea and vomiting.

Ondansetron is administered in the form of tablets, oral solution, or injections, depending on the patient's needs. It is effective in preventing both acute and delayed nausea associated with cancer treatments or postoperative care.

Common side effects include headache, constipation, fatigue, or dizziness. In rare cases, it may cause allergic reactions or heart rhythm disturbances. It is important to use ondansetron as prescribed by a healthcare provider, and patients with heart conditions or those taking other medications should inform their doctor to avoid potential interactions.
