What it is used for
- High blood pressure (hypertension)
- Heart failure
- Reducing the risk of heart attack and stroke in high-risk people
- Protecting the heart after a heart attack
How it works
Ramipril blocks an enzyme that produces a hormone (angiotensin II) that narrows blood vessels. With less of this hormone, vessels relax and widen, lowering blood pressure and reducing the workload on the heart.
How it is taken
Taken by mouth as a tablet or capsule, usually once a day with or without food. Take it exactly as your doctor or pharmacist directs and follow the label. Do not stop on your own; your clinician may check kidney function and potassium with blood tests.
No doses here on purpose. The right strength and schedule depend on you — only a doctor or pharmacist should set them. Always follow your prescription and the label.

- Dizziness, especially when standing
