Hi You are taking two anti hypertensive medications amlodipine and perindopril.Both of them are very safe drugs and are used extensively for this purpose. Breathlessness as a symptom has variety of reasons : asthma/naso-bronchial allergy anemia cardiac problems e.g heart failure , diastolic dysfunction other systemic problems like renal failure psychogenic/anxiety As you can see there are varied reasons for this symptom, both the drugs should not be the reason of the breathlessness, although coversyl can cause dry cough,which may give a feeling of little shortness of breath. I will advise you to consult your doctor to get the basic investigations done to rule out any serious problem. Hope it helps.
