High blood pressure in adults
Moexipril is an angiotensin-converting enzyme (ACE) inhibitor. It works by blocking a protein in your body called ACE from squeezing your blood vessels. Blocking ACE helps relax your blood vessels and lower your blood pressure.

Take moexipril 1 hour before food. You should take it on an empty stomach because food can lower how much of the medication gets absorbed into your body.
Moexipril can make you feel dizzy, especially when you first start taking the medication and when your dose is raised. This should get better as your body gets used to your new blood pressure. To lower your risk of falls, make sure to stand up slowly and carefully from a sitting or lying down position.
Drink plenty of water to stay hydrated while you're taking moexipril, especially on hot days or after exercising. Your blood pressure might drop too much if you don't have enough fluids in your body. This can worsen dizziness and raise your risk of falls. Ask your provider about how you can stay hydrated in a safe way if you have heart failure or kidney problems.
Check your blood pressure at home and write down your readings. Bring your log to your office visits so you can talk with your provider about how well moexipril is working for you and whether your dose needs to be changed.
Mark your appointments on your calendar for any blood work you need while you're taking moexipril. These blood tests help your provider check for side effects, like changes in your potassium levels or kidney health. Your dose might need to be adjusted based on your lab results.
Make sure to tell your providers about all the medications you're taking or planning to take. Moexipril can interact with other medications. These interactions can affect how well your medications work or raise your risk for side effects. Your providers and pharmacists can check that your medications are safe to take together.
Don't use nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil), with moexipril unless your provider says it's okay. Taking these medications with moexipril can raise your risk for kidney problems.
Make sure to eat a variety of fruits and vegetables, follow a low-salt diet, and get regular exercise while you're taking moexipril. This helps lower your blood pressure. You might be able to stop taking the medication if your blood pressure is well-controlled with these lifestyle changes.
Stop taking moexipril and tell your provider right away if you're pregnant. This medication isn't safe to take during pregnancy because it can harm your unborn baby. Your provider might recommend a different medication that's safer during pregnancy and lifestyle changes you can make to help lower your blood pressure.
Moexipril can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Moexipril can cause severe and sometimes life-threatening harm to unborn babies. For this reason, avoid using this medication during pregnancy. Before you start moexipril, discuss with your provider about safer options to treat your blood pressure if you're pregnant or thinking of becoming pregnant. If you become pregnant while you're taking moexipril, stop the medication and let your provider know right away.
Risk factors: Black people | History of angioedema in the past
People who take ACE inhibitors like moexipril can experience a rare, but serious side effect called angioedema. This involves swelling in different parts of the body, including the face, throat, tongue, and stomach. 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. You might be more likely to experience angioedema if you're Black, an older adult, or of female sex. Get medical attention immediately if you notice any unusual swelling, stomach pain, or difficulty breathing. You'll have to stop taking moexipril if this happens.
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 | Dialysis | Heart failure
Taking moexipril can sometimes cause your blood pressure to drop too much. This can make you feel dizzy, tired, or lightheaded. This side effect is more common when you first start moexipril or when your provider raises your dose. Make sure to stay well-hydrated during treatment. Sit or lie down slowly while holding onto something if you feel dizzy, lightheaded, faint, or tired. And get medical help right away if you accidentally fall and hit your head.
Risk factors: Severe heart failure | Kidney problems or renal artery stenosis | Not enough fluid in your body | Taking other medications that can cause kidney damage
Moexipril 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 kidney damage from severe heart failure. Your provider might order lab tests every so often to make sure your kidneys are healthy and working properly. Tell your provider if you're urinating less often than usual, as this could be a sign that your kidneys aren't working as well.
Risk factors: Diabetes | Kidney problems | Taking other medications that also raise potassium
Moexipril can raise the amount of potassium in your body, which can sometimes be dangerous. Your risk of having high potassium levels is greater if you have diabetes or kidney problems or if you're 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 you start treatment. Tell your healthcare provider right away if you have symptoms of high potassium levels, such as nausea, muscle weakness, or abnormal heartbeat.
In some rare cases, people who took ACE inhibitors like moexipril developed a blocked bile duct. This condition can lead to liver problems or liver failure. Your provider might order blood tests to check your liver health from time to time. Let your provider know right away if you notice symptoms of liver problems, such as tiredness, stomach pain, or yellowing of your skin.
The typical dose is 7.5 mg to 30 mg per day taken by mouth an hour before meals. It can be taken as a single dose or split into two equal doses during the day.
Your provider will adjust your dose depending on your kidney function, how well the medication helps lower your blood pressure, and whether you're having side effects.
