Ondenstar 2mg Syrup is a medicine given to children to help treat nausea and vomiting. It is mainly given to treat nausea and vomiting associated with surgery, chemotherapy, radiotherapy, and stomach/intestinal infection. It also helps treat vomiting that is caused as a side effect of medicines like painkillers.

Ondenstar 2mg Syrup may be given before or after meals. To control vomiting caused due to chemotherapy, give this medicine to your child 30 minutes before the procedure. Give it 1 to 2 hours before a radiotherapy session and 1 hour before surgery to prevent your child from vomiting post these procedures. If your child expels out the medicine within 30 minutes of the intake, help your child calm down and repeat the dose. Do not double dose if it is already time for the next dose.

Ondenstar 2mg Syrup may cause some temporary side effects such as headache, constipation, diarrhea, and fatigue. These side effects usually subside once your child’s body adapts to the medicine. In case these side effects persist or become bothersome, do reach out to the doctor on a priority basis.

Let the doctor know about all the medicines your child is taking, including painkillers, antibiotics, or medicines taken to treat depression. Also, inform the doctor if your child has a history of liver problems, kidney malfunction, blockage in the gastrointestinal tract, heart problems, or allergies to any medicine, its ingredients, or a food product. This information is very important for dose alterations and for planning your child’s overall treatment.

How Ondenstar Syrup works

During radiotherapy, chemotherapy, abdominal infection, or any major surgeries, the dead cells in the body start releasing a chemical called serotonin directly into the blood. Later, this stimulates special centers in the body that are responsible for inducing vomiting in your child. Giving Ondenstar 2mg Syrup just before the procedure helps block the effect of this chemical on vomiting centers of the brain and prevents vomiting.
