Key takeaways
Fosinopril (generic, brand name Monopril no longer available) and Ramipril (generic, brand name Altace no longer available) are both ACE inhibitors used to treat high blood pressure and heart failure. Fosinopril is typically taken once daily, while Ramipril can be taken once or twice daily depending on the dose. Fosinopril is also used to protect the kidneys in people with diabetes, a benefit not mentioned for Ramipril. Both medications can cause a dry cough and dizziness, but Ramipril is noted to cause headaches and feelings of tiredness more commonly. Fosinopril starts working within 1 hour and takes 1-2 weeks to fully kick in, whereas Ramipril starts lowering blood pressure within 1-2 hours but may take a few weeks to find the best dose. Both medications are not safe during pregnancy and can cause serious side effects like angioedema and high potassium levels. However, Ramipril has additional warnings for liver problems and lower blood cell counts.
