Ondansetron 4mg Tablets

Product Introduction

Ondansetron 4mg OD is an antiemetic used to prevent or treat nausea and vomiting related to surgery, chemotherapy, radiotherapy, gastroenteritis, or other clinician-assessed causes. It blocks 5-HT3 serotonin receptors involved in nausea signaling between the gut and brain. Oral-disintegrating forms are useful when swallowing is difficult, while injections are used in supervised settings.

How to use

Use Ondansetron 4mg OD as prescribed for the nausea trigger. For OD tablets, follow the dissolve-in-mouth instructions. Injectable ondansetron should be administered by trained staff.

How it works

Ondansetron blocks 5-HT3 receptors in the gut and central nervous system, reducing nausea and vomiting signals.

Common side effects

Possible effects include headache, constipation, dizziness, flushing, or fatigue. Urgent review is needed for abnormal heartbeat symptoms, serotonin-syndrome features, severe allergy, or signs of bowel obstruction.

Important information

Before use, review rhythm problems, electrolyte imbalance, liver disease, bowel-obstruction symptoms, pregnancy, breastfeeding, and medicines that affect serotonin or QT interval.
