How ondem oral solution 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 Ondem Syrup just before the procedure helps block the effect of this chemical on vomiting centers of the brain and prevents vomiting.

Frequently asked questions FOR Ondem 2mg/5ml Oral Solution

Ondansetron

Q. What is Ondem Syrup used for?
Ondem Syrup is generally given before any major surgery or before chemotherapy and radiotherapy sessions. In case your child is about to undergo any of the above procedures, the doctor may ask you to give Ondem Syrup to your child to prevent vomiting post-procedure. Apart from this, Ondem Syrup is also found useful in treating vomiting caused due to diseases of the stomach. In such a case, your child’s doctor may prescribe giving Ondem Syrup to your child for a few days. Stick to the dose for best results.
Q. What if my child takes too much Ondem Syrup?
Ondem Syrup is unlikely to cause harm if you give an extra dose by mistake. However, you must still speak to your child’s doctor immediately. Sometimes, excessive intake of Ondem Syrup can cause some serious side effects like excess sleepiness, agitation, rapid heartbeat, hypertension, flushing, dilated pupils, sweating, involuntary muscle jerk, uncontrolled eye movements, overactive reflexes, and seizures. These symptoms are collectively known as serotonin syndrome. If any of these appear, consult the doctor without any delay.
Q. How should Ondem Syrup be stored?
Ondem Syrup should be stored at room temperature, in a dry place, away from direct heat and light. Also, keep all the medicines out of the reach and sight of children to avoid any accidental intake.

Q. Can other medicines be given at the same time as Ondem Syrup?
Ondem Syrup can sometimes interact with other medicines or substances. Tell your doctor about any other medicines your child is taking before starting Ondem Syrup. Also, check with your child’s doctor before giving any medicine to your child.
Q. In what conditions do I need to call my child’s doctor right away?
Call your child’s doctor immediately if your child develops symptoms of serotonin syndrome like irregular heartbeat, green-colored vomiting, inability to pass wind, pale skin and eyes, dark-colored urine, restlessness, and insomnia.
Q. My child is having a migraine and is on medication. Can I give Ondem Syrup along with it?
Avoid combining Ondem Syrup with such medicines because concomitant use of Ondem Syrup with medicines meant to treat depression or migraine results in serotonin syndrome. Consult your child’s doctor before giving any medicine to your child.
