Zofer MD 4 Tablet contains Ondansetron 4 mg, a selective 5-HT3 receptor antagonist used primarily for the prevention and treatment of nausea and vomiting associated with chemotherapy, radiotherapy, and postoperative recovery. Ondansetron acts by blocking serotonin receptors in the central nervous system and gastrointestinal tract, thereby inhibiting the emetic signals transmitted to the vomiting center in the brain. This medication is indicated for patients undergoing cancer treatment who experience acute nausea and vomiting, as well as for individuals who develop nausea following surgical procedures. Zofer MD 4 Tablet is administered orally and is generally well tolerated, with a favorable safety profile. Common adverse effects may include headache, constipation, dizziness, and fatigue, though serious side effects are rare. It is important to use this medication under medical supervision, particularly in patients with hepatic impairment or those taking other medications that may prolong the QT interval. Dosage adjustments may be necessary based on clinical response and patient condition. Zofer MD 4 Tablet should not be used in patients with known hypersensitivity to Ondansetron or other 5-HT3 antagonists. Proper adherence to prescribed dosing schedules enhances therapeutic outcomes and improves patient comfort during treatment.
