Shankhpushpi and Brahmi syrup should be taken for the duration recommended by a doctor, depending on the child’s needs. As of now, no long-term side effects have been reported, but if your child experiences any unusual symptoms, it is essential to inform the doctor and follow appropriate measures. Stopping the syrup is generally safe and does not harm the child, but maintaining a healthy diet, proper lifestyle, and following any techniques recommended by the doctor is important to support memory and concentration.
