Using more than the recommended dose will never be more effective for your child. Excess or prolonged intake of Grilinctus-BM Paediatric Syrup may put your child at risk of developing serious side effects like rapid heart rate, cognition defects, seizures, depression, and inability to concentrate. A standard dosage like 5–10 drops twice or thrice a day is designed to avoid such side effects. Always follow your physician’s recommended dosage.
