Ramipril is an angiotensin-converting enzyme (ACE) inhibitors. This medication treats high blood pressure by relaxing blood vessels. It can also ease heart failure symptoms after a heart attack. Ramipril is taken by mouth, typically once or twice daily, by adults. Some of the more common side effects of this medication include headache, dizziness, and feeling tired. Ramipril is generic only because the brand name Altace is no longer available.
Ramipril is an angiotensin-converting enzyme (ACE) inhibitor. It blocks ACE, a protein in your body that tightens blood vessels. In doing so, ramipril relaxes your blood vessels and causes your blood pressure to go down.

Risk factors: Black people | Older adults | Female | Having angioedema in the past
People who take an ACE inhibitor, like ramipril, can experience a rare, but serious side effect called angioedema. This involves swelling in different parts of the body, including the face, throat, and tongue. Swelling of the tongue or throat area can be potentially life-threatening, since it can make it difficult to breathe.
Angioedema can happen at any time during treatment. Your provider will ask you to stop the medication if you have symptoms. Get medical attention right away if you experience swelling in any of the areas mentioned above, stomach pain, or difficulty breathing.
Although rare, ramipril can cause a life-threatening allergic reaction (e.g., anaphylaxis). If you experience trouble breathing, hives, or swelling in your face or throat, get medical help right away.
Risk factors: History of liver problems | Drinking large amounts of alcohol
In some rare cases, people who took ramipril have developed life-threatening liver problems. If you notice symptoms of liver problems, such as nausea, stomach pain, or yellowing of your skin or whites of your eyes, let your provider know right away.
Risk factors: Severe heart failure | Kidney problems | Not enough fluid in your body | Taking other medications that can cause kidney damage | History of blocked kidney blood vessels (renal artery stenosis)
Ramipril is usually good for the kidneys. But in some cases, it can make kidney problems worse. The risk is higher for people who have certain types of kidney problems, such as renal artery stenosis or very severe heart failure. Your provider might order lab tests every so often to make sure your kidneys are healthy and working properly. Your provider will check your kidneys before starting ramipril and regularly as needed. Let your provider know if you're urinating less often than usual, as this could be a sign that your kidneys aren't working as well.
Let your provider know if you've collagen-vascular condition, such as lupus or rheumatoid arthritis. If so, you might be at higher risk for developing lower blood cell counts while taking ramipril, especially if you also have kidney problems. Your provider might order blood tests more often to check you blood cell counts.
Risk factors: Not enough fluid in your body | Having diarrhea or vomiting for a long time | Low salt levels in your body | Taking higher doses of diuretic medications
Sometimes, taking ramipril can cause your blood pressure to drop too much. This can cause you to feel dizzy, tired, or lightheaded. This side effect is more common when you first start ramipril or when the dose is raised. Make sure to stay well-hydrated. If your blood pressure drops too much and you feel dizzy, make sure to sit down slowly while holding onto something and let your provider know. If you fall and hit your head, get medical help right away. If you feel dizzy, lightheaded, faint, tired, or confused while taking ramipril, contact your provider right away.
Risk factors: Diabetes | Kidney problems | Taking other medications that also raise potassium
Some people who took ramipril developed high potassium levels, which can be dangerous. The risk is higher for people who've diabetes, kidney problems, or are taking other medications that also raise potassium levels. For this reason, make sure your provider knows your full medical history and what medications you're taking before starting ramipril. If you experience signs of high potassium levels, such as nausea, muscle weakness, or abnormal heartbeat, tell your healthcare provider right away.
Taking ramipril can cause dry cough. This side effect can happen anytime after you start taking the medication. This isn't a side effect your body will adjust to. If it's bothersome, your provider might recommend that you take a different blood pressure or heart failure medication. This cough should go away after stopping the medication.
High blood pressure: The typical dose is 2.5 mg to 20 mg by mouth total per day. Smaller doses are usually taken once a day, but larger doses can be split into two doses throughout the day.
Heart failure after heart attack: The typical starting dose is 2.5 mg by mouth twice a day. After 1 week, your provider might slowly raise your dose over time. The typical maintenance dose is 5 mg twice daily.
Your dose might differ if you have kidney problems.
