Hello thanks for asking from HCM for your health related queries I can understand your concern. Cipralex is Escitalopram and Lamictal is Lamotrigine. Abrupt stoppage of drug after regular use or reducing the doses rapidly can result in withdrawal symptoms in form of rebound anxiety, restlessness, some times dizziness and brain fog like situation. You have symptoms like racing heart, terrible feelings and these could be occurring due to anxiety and possibly due to withdrawal from Cipralex. In my opinion restarting the drug would help you in these symptoms. Wait for about 3-4 weeks to see improvement because the drug takes time to show its effects. Reduce the doses of Lamictal gradually and with proper advise of your psychiatrist. Thanks, Hope this helps you. Take care Dr. Seikhoo Bishnoi, Consultant Psychiatrist
