What is Inspra?
Inspra (eplerenone) is a treatment used to help people who have heart failure or high blood pressure.
Heart failure means the heart is not pumping blood as well as it should. Inspra helps improve survival in people who have had a recent heart attack and now have symptoms of heart failure with reduced ejection fraction.
Inspra is also used to treat high blood pressure, also known as hypertension. High blood pressure makes the heart and blood vessels work too hard, which can lead to stroke, heart attack, or other serious problems.
Inspra lowers blood pressure, which helps protect the heart and brain. It can be used alone or in combination with other drugs for better results.
How Does Inspra Work?
Inspra works by blocking a natural substance in the body called aldosterone. Aldosterone is made in the adrenal glands and plays a key role in controlling blood pressure by telling the kidneys to hold on to salt and water.
Too much aldosterone can lead to high blood pressure and can put stress on the heart. Inspra blocks aldosterone from attaching to special parts of cells called mineralocorticoid receptors.
These receptors are found in the kidneys, heart, blood vessels, and brain. By blocking aldosterone, Inspra helps remove extra salt and water from the body, lowers blood pressure, and eases the workload on the heart.
Inspra Dosage and Administration
Inspra is available in tablet form and has two strengths: 25 mg and 50 mg. It is usually taken orally once or twice daily, with or without food.
Your doctor will choose the correct dose based on your health condition, blood pressure, and blood test results.
You may need regular checkups to measure potassium levels in your blood, as high potassium can be dangerous.
Dosage Form and Strengths of Inspra
- 25 mg tablet
- 50 mg tablet
How to Take Inspra?
- Take Inspra by mouth, once or twice daily as directed by your doctor.
- You can take it with food or without food.
- Try to take it at the same time each day to help you remember.
- Do not change your dose unless your doctor tells you to.
- Your doctor may order blood tests to check potassium and kidney function.
- If you miss a dose, take it as soon as you remember. Skip it if it is almost time for your next dose.
- Do not take two doses at the same time.
- Use Inspra even if you feel fine, especially with high blood pressure.
- Contact your doctor if you notice unusual symptoms like weakness, irregular heartbeat, or muscle cramps.
Recommended Dosage
For Heart Failure After a Heart Attack
The starting dose is 25 mg once daily. After about four weeks, if your body can handle it well, the dose may be increased to 50 mg once daily.
Your doctor will monitor your blood potassium levels to guide any dose adjustments. If your potassium level is too high, your doctor may reduce your dose or stop Inspra until it improves.
Increase the dose if the potassium is less than 5.0. Lower the dose if it exceeds 5.5. Stop treatment if potassium reaches 6.0 or higher until levels become safer.
For High Blood Pressure (Hypertension)
The recommended starting dose is 50 mg once daily. It can take about 4 weeks to see the full effect. If your blood pressure is still high, your doctor may increase the dose to 50 mg twice daily.
Taking more than 100 mg daily is not recommended because it does not work better and may raise your risk of side effects, such as high potassium levels.
Important Monitoring
Before you start Inspra, your doctor will check your blood potassium. It will be checked again during the first week and about a month after starting treatment, and then from time to time.
If you also take certain antibiotics, antifungal drugs, or blood pressure drugs, your doctor may need to monitor your potassium and kidney function more closely.
For People Taking Certain Other Drugs
If you are taking drugs that affect liver enzymes (like verapamil, fluconazole, or erythromycin), the starting dose of Inspra should be 25 mg once daily.
Doctors may increase the dose to 25 mg twice daily, but will not go higher. They do this to reduce the risk of side effects, especially high potassium levels.
Side Effects of Inspra
Inspra may cause both common and serious side effects. Some people may experience mild problems like dizziness or headache, while others may face more serious effects like high potassium levels or kidney issues. Monitoring your feelings while taking Inspra and reporting anything unusual to your healthcare provider is important.

Warnings and Precautions for Inspra
Before using Inspra, knowing that it can raise potassium levels in your blood is important. This risk is higher if you have kidney problems, diabetes, or protein in your urine. Some drugs can also increase this risk. Always tell your doctor about your health history and everything you are taking to avoid serious problems.
- You should not use Inspra if you have very high potassium levels in your blood. This condition is called hyperkalemia, and it can lead to serious heart problems.
- You should not take Inspra if you have severe kidney problems. When your kidneys are not working well, the risk of potassium building up in your blood increases.
- People with type 2 diabetes who have too much protein in their urine should not use Inspra. This combination can raise the risk of dangerous side effects, especially high potassium.
- Let your doctor know if you are allergic to eplerenone, the main ingredient in Inspra. Allergic reactions can be severe and include symptoms like rash, swelling, or trouble breathing.
- Do not use Inspra with potassium supplements or salt substitutes that contain potassium. This can raise potassium levels too high and make them unsafe.
- Avoid using Inspra with water pills like spironolactone, triamterene, or amiloride. Taking these together can increase potassium too much and may harm your kidneys or heart.
- Avoid taking antibiotics like clarithromycin or telithromycin with Inspra. They alter how your body processes the drug and increase side effects.
- Do not take antifungal drugs like ketoconazole or itraconazole with Inspra. These drugs may increase the amount of Inspra in your body and raise the risk of side effects.
- HIV medications like ritonavir, indinavir, or saquinavir interact with Inspra. These combinations cause harmful effects and require avoidance.
- Tell your doctor if you have had kidney disease in the past. Even mild kidney problems can raise your risk of side effects from Inspra.
- Let your doctor know if you have diabetes. This condition, especially if uncontrolled, can affect how your body handles potassium and increase your risk of problems.
- Tell your doctor if you have liver disease. The liver helps process many drugs, and liver issues may affect how Inspra works in your body.
- Let your doctor know if you have high cholesterol or high triglycerides. These may not directly affect how Inspra works, but are important for your overall heart health.
- Tell your doctor about other drugs you take for heart or blood pressure problems. Some may not work well with Inspra or raise the risk of side effects.
- If you are pregnant or planning to become pregnant, tell your doctor. High blood pressure and heart problems during pregnancy can lead to serious risks for both mother and baby.
- Let your doctor know if you are breastfeeding. It is not clear if Inspra passes into breast milk or could affect your baby.
- Inspra may affect fertility in men. It can lower the ability to have children in some cases, especially with long-term use.
- Your doctor may lower your dose of Inspra if you take certain other drugs. These include drugs that affect how your liver breaks down Inspra, which can raise its levels in your body.
- You will likely need regular blood tests while taking Inspra. These tests help check your potassium and kidney function to keep you safe.
