Hello, The medicines you are taking are all anti-hypertensives. They do not have any significant side effects except that they can cause an occasional drop in your blood pressure. I would suggest that you check your BP on a regular basis at home as well. Have your primary physician titrate the doses and ensure that you are not being over medicated. If you continue to have a high BP despite this combinations of medicines, have your doctor check for other causes of increased blood pressure like renal artery obstructions and hormone imbalances. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Pranav Balakrishnan, General & Family Physician
