[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Light headdress in hypertensive patient can be due to sudden rise or fall in blood pressure. So better to consult your doctor and get done blood pressure monitoring and stress test (trade mill test) to see for any fluctuations in blood pressure. If your BP is falling then you should avoid lisinopril. But if your blood pressure is rising then you may need another antihypertensive Chat Doctor.  Don't worry, you will be alright. Consult your doctor and discuss all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
