Onton Syrup is an antiemetic medicine. It is used in the treatment of paediatric gastroenteritis in infants and children aged 6 months to 12 years. It is also used in the prevention of nausea and vomiting associated with moderately emetogenic cancer chemotherapy in children aged six months and above. Nausea is an uneasy feeling in which a person feels an urge to vomit, while vomiting is the natural response to the body to forcefully discharge the stomach contents.

Onton Syrup contains 'Ondanestron', which belongs to serotonin 5-HT3 receptor antagonists. It works by blocking the action of a chemical called serotonin in the body, which is responsible for causing nausea and vomiting. As a result, Onton Syrup prevents the sensation of nausea and vomiting caused by cancer chemotherapy.

Onton Syrup may cause certain side effects in your child, such as feeling of warmth, headache, diarrhoea, and stomach pain. These side effects generally resolve over time. However, if it does not resolve, stop giving this medicine to your child and contact the paediatrician. Do not give more than the prescribed dose of Onton Syrup to the child. Onton Syrup can be given with or without food. The dose of the medicine will be decided by your paediatrician.

Nausea/Vomiting: Nausea is an uneasy feeling in the stomach that may come and go in waves in which a person feels a strong urge to vomit. It happens before vomiting. Vomiting is the forcible voluntary or involuntary emptying of stomach contents through the mouth. Usually, your child can face nausea and vomiting as the unpleasant effects of cancer therapy after chemotherapy. It is essential to control vomiting and nausea in cancer patients for performing everyday activities of the day. If not controlled, it can lead to mental changes, loss of appetite, malnutrition, and dehydration. Onton Syrup is used in the treatment of moderately emetogenic cancer chemotherapy in children.
