About Ondex Syrup
Ondex Syrup is a medication designed to help children cope with feelings of nausea and episodes of vomiting. Primarily, this syrup is prescribed to address symptoms of nausea and vomiting that are often experienced after surgical procedures, chemotherapy sessions, radiotherapy treatments, or due to stomach and intestinal infections. Additionally, Ondex Syrup is beneficial in managing vomiting triggered by the side effects of certain medications, such as painkillers.
In terms of administration, Ondex Syrup can be given either before or after meals, depending on the specific situation. For children undergoing chemotherapy, it is advised to administer the syrup 30 minutes before the procedure to effectively control any potential vomiting. Prior to radiotherapy sessions, the recommended timing for giving the medicine is 1 to 2 hours before the treatment. Similarly, when preparing for surgery, provide the syrup to your child approximately 1 hour in advance to help prevent postoperative vomiting. If the child vomits out the syrup within 30 minutes of intake, it is recommended to offer comfort and reassurance to the child and then repeat the dose; however, doubling the dosage should be avoided if the next scheduled dose is imminent.
While Ondex Syrup is generally well-tolerated, some temporary side effects may occur, including headache, constipation, diarrhea, and fatigue. Typically, these side effects tend to diminish as the child's body adjusts to the medication. If these side effects persist or become bothersome, it is essential to promptly seek medical advice from a healthcare professional.

Therefore, it is essential to seek professional medical advice before making any changes in the medication routine to ensure the safety and well-being of your child throughout their treatment journey.
