Hello, I have gone through your query and understand your concern. You are suffering from Hypertension and Diabetes. You have to understand that both are non curable diseases and can be well controlled by Medications and Lifestyle changes. Thus you have to take the medications to control your blood pressure and Blood sugar. In addition you need some life style changes like regular exercise and diet modification. Coming to your question about side effects. Any drug have both advantages like curing and controlling diseases and disadvantages like Side effects and allergies. Metpure XL 50 contain Metaprolol, an Beta blocker for controlling blood pressure. It can cause dizziness, weakness, sweating, blurred vision etc. It varies from person to person and it will normalize in few weeks or months as your body adjusts and nothing to be concerned about this.
