Moexipril (Oral)

Moexipril treats high blood pressure, as well as congestive heart failure, diabetes, and certain types of renal dysfunction.


High blood pressure is a commonly diagnosed cardiovascular condition that occurs when the amount of pressure against artery walls when blood goes through them is too high. Moexipril is an angiotensin converting enzyme (ACE) inhibitor often prescribed by doctors to treat patients with this condition. This medication is designed to widen blood vessels by relaxing them so blood flows more easily throughout the body, which in turn lowers a person's blood pressure. Lowering a patient's blood pressure lessens the risk of them having heart attacks, stroke, kidney issues, or other medical conditions later on.

Less commonly, moexipril is prescribed for patients with diabetes to protect their kidneys from damage due to their condition. It is often combined with diuretics to treat patients diagnosed with congestive heart failure.

While this medication is most commonly prescribed to treat high blood pressure, it is not a cure for the condition. An overall treatment plan for the condition includes patients making changes in their dietary and exercise habits in combination with this and other medications.

Before you start taking moexipril, inform your doctor or pharmacist of any allergies you have to it or other ACE inhibitors (like captopril, lisinopril, or memantine), or if there are any other allergies you have. This medication could contain inactive ingredients that can cause either allergic reactions or other medical problems.

Before you begin using this medication, talk to your doctor about your medical history, especially if that medical history includes allergic reactions like angioedema (swelling in the throat, tongue, lips, or face), blood filtering procedures like dialysis or LDL apheresis, high potassium levels in your blood, or liver disease.

Before you undergo any surgery, tell the doctor or dentist performing it about everything you are taking, including this medicine, other prescription medications, nonprescription drugs, and vitamins and supplements.

Because this medicine can make you dizzy, you should not drive, use machinery, or perform any other activity that requires you to be alert until you can do so safely.

While taking this medication, report any prolonged periods of diarrhea or vomiting to your doctor. Too much diarrhea, vomiting or sweating can result in dehydration (loss of body water). They can also increase the risk of becoming lightheaded. Make sure you are drinking enough fluids to stay hydrated unless otherwise directed by your doctor.

If you start having a fever, chills, or sore throat, check in with your doctor. These could be signs that you have an infection due to a low white blood cell count.

Talk to your doctor as soon as possible if you see any signs or symptoms of liver problems. Symptoms include appetite loss, nausea or vomiting, pale stools or dark-colored urine, stomach pain, and yellow eyes or skin.

It is possible for high potassium levels (hyperkalemia) to occur while using this medication. Let your doctor know as quickly as possible if you experience any of the symptoms of this condition. Symptoms include confusion, having trouble breathing, having an irregular heartbeat, feelings of heaviness or weakness in your legs, nervousness, nausea or vomiting, shortness of breath, stomach or abdominal pain, or tingling or numbness in your lips, feet, or hands.

Consult with your doctor before using salt substitutes or supplements with potassium. Also discuss your use of certain over-the-counter medicines for asthma, coughs and colds, sinus problems, hay fever, or controlling your appetite. These medicines have been known to raise your blood pressure.

Some groups of people, especially older adults, could be more sensitive to certain side effects of this medication, such as high levels of potassium and dizziness. Other groups may be less sensitive to this medication's intended effects. Talk to your doctor for more information.

If you have severe stomach pains (whether or not you are nauseous or vomiting), contact your doctor immediately. You may be experiencing intestinal angioedema.

If you are a woman of child-bearing age, make sure to use an effective form of birth control in order to prevent pregnancy from occurring. If you are pregnant or trying to become pregnant, do not use this medication. It may have harmful effects on an unborn child. Talk to your doctor immediately if you think you might have become pregnant while taking this medication.

If you are nursing, talk to your doctor before using this medication, as it is not known at this time if this medication is excreted into breast milk.

Hypertension, or high blood pressure, is a serious condition that affects many people. If it is not treated, properly, it can lead to medical conditions that are much more severe - like heart disease, a heart attack, or a stroke, to name a few. Moexipril, when used properly for this specific condition, relaxes blood vessel walls and lowers a patient's blood pressure so the damage that leads to more serious medical conditions lessens or is completely stopped.

While this medication can be an effective part of an overall treatment plan for high blood pressure, there are many risks associated with its use, especially if a patient is already taking medications for other medical conditions. Doctors know what the potential benefits and risks are, but it can be difficult for them to correctly determine what benefit this medication could be for their patient without a more complete picture of their patient's overall medical condition.

For this reason, and many others, patients need to be willing to have open and honest conversations with the medical professionals working with them about their medical history and everything they know about their family's medical history, as well as any medications, vitamins, supplements, and herbal products they are using and their dietary habits. With this information available, it is easier for doctors to determine the risks involved in treating their patient with moexipril and if the benefits outweigh them. Without this information, however, it will take a doctor much longer to come to the same conclusion, and it is possible for more damage to occur in the meantime.

When this medication is administered correctly, it is an effective part of an overall treatment plan for high blood pressure. Combined with changes in diet and exercise habits, patients are less likely to experience more severe medical conditions and can expect to enjoy living a much longer life in much better health overall.
