What is Ondem?

Ondem is a medication prescribed for the treatment of nausea and vomiting that occurs due to certain medical conditions. It belongs to the anti-emetics class of medications and works by inhibiting the release of a chemical called serotonin.

It is mainly used for treating nausea and vomiting associated with surgery, chemotherapy, radiotherapy or stomach/intestinal infection, as well as to prevent nausea and vomiting that one experiences due to medicines such as painkillers. It is also useful to prevent nausea and vomiting caused by pregnancy and motion sickness.


How To Take Ondem?

Ondem Of 4 MG Tablet is taken by mouth in the form of a tablet, disintegrating (dissolving) tablet, or solution and film. It can be taken orally with or without food, but it is not advisable to take it with alcohol as this may worsen the effects of the medicine.


Mechanism of Action

Ondansetron binds to a receptor called CTZ in the brain that triggers nausea and vomiting. It works by blocking the release of this chemical from the gut and central nervous system, which prevents nausea and vomiting.



The recommended dosage of Ondem depends on the age, weight, and medical condition of the patient. It is a short-acting medication that takes effect within 30 minutes of being taken.

Use Ondem Syrup with caution in children below 4 years of age as it can cause some side effects such as headache, constipation, and diarrhea. However, these are temporary and will go away on their own once your child's body adapts to the medicine.


How Ondem Works
