An Overview of Lisinopril – Uses, Side Effects, and Dosage Guidelines

Overview of Lisinopril:

Lisinopril is a common medication used to treat high blood pressure (hypertension). It belongs to a class of drugs known as ACE inhibitors, which work by relaxing blood vessels to allow for easier blood flow, thus lowering blood pressure.

Lisinopril is typically prescribed by healthcare providers to help manage hypertension and reduce the risk of heart attacks, strokes, and kidney problems. It is often recommended as a first-line treatment for high blood pressure due to its effectiveness and relatively low risk of side effects.

Some common brand names for lisinopril include Prinivil and Zestril. It is available in tablet form and is usually taken once daily, with or without food. The dosage may vary depending on the individual’s medical condition and response to treatment.

It is important to take lisinopril exactly as prescribed by your healthcare provider to ensure optimal results. Missing doses or stopping the medication abruptly can lead to a sudden increase in blood pressure and other complications.

Common side effects of lisinopril may include dizziness, fatigue, cough, and headache. It is important to inform your healthcare provider if you experience any severe side effects while taking lisinopril.

Common Dosage Forms and Strengths of Lisinopril:

Lisinopril is available in several dosage forms and strengths, including tablets and oral solution. The typical dosage strengths for lisinopril tablets are 2.5 mg, 5 mg, 10 mg, 20 mg, and 40 mg. The oral solution is often available in a 1 mg/mL concentration. The choice of dosage form and strength may vary based on the patient’s condition and the prescribing healthcare provider’s recommendation.

It is essential to follow the prescribed dosage and administration instructions provided by the healthcare provider to ensure the optimal therapeutic effect of lisinopril.

Lisinopril Dosage and Administration


When starting Lisinopril treatment, the usual initial dosage for adults with hypertension is 10 mg once daily. The dosage may then be adjusted based on the individual’s blood pressure response.

For pediatric patients (6 years and older), the recommended starting dose is 0.07 mg per kg of body weight up to a maximum of 5 mg once daily.


For adults, the dosage may be titrated upward as needed, typically at intervals of 2 to 4 weeks. The usual maintenance dosage range is 20 to 40 mg per day, taken as a single dose or divided into two doses.

In pediatric patients, the dosage may be increased gradually to a maximum of 20 mg per day depending on the response to treatment.


Lisinopril is usually taken by mouth with or without food. It should be taken at the same time each day to ensure consistent blood pressure control.

If a dose is missed, it should be taken as soon as remembered unless it is almost time for the next dose. In that case, the missed dose should be skipped, and the regular dosing schedule should be resumed.

Special Populations:

For patients with renal impairment, the dosage may need to be adjusted based on creatinine clearance levels.

Elderly patients may require lower starting doses due to potential age-related decreases in renal function.


Regular blood pressure monitoring is essential during Lisinopril treatment to assess the effectiveness of the medication and adjust the dosage as needed. In addition, monitoring of renal function and electrolytes is recommended, especially in patients with pre-existing renal conditions.

Adverse Effects:

Common adverse effects of Lisinopril include dizziness, headache, cough, and fatigue. Patients should report any severe or persistent side effects to their healthcare provider.

In rare cases, Lisinopril may cause angioedema or hyperkalemia, which require immediate medical attention.

Benefits of Lisinopril for Hypertension Treatment

Lisinopril offers a range of benefits for individuals with hypertension. It is a highly effective medication that helps to lower blood pressure and reduce the risk of cardiovascular complications. Here are some key advantages of using Lisinopril:

  • Lowering Blood Pressure: Lisinopril works by relaxing blood vessels, allowing blood to flow more smoothly and reducing the pressure on the walls of the arteries. This helps to decrease overall blood pressure levels, which is crucial for managing hypertension.
  • Cardiovascular Protection: In addition to reducing blood pressure, Lisinopril also offers cardiovascular protection. By lowering blood pressure, this medication can help reduce the risk of heart attacks, strokes, and other cardiovascular events.
  • Kidney Function Improvement: Lisinopril has been shown to improve kidney function in patients with hypertension. By reducing the pressure on the kidneys and improving blood flow, this medication can help preserve kidney health and function.

According to a study published in the American Heart Association Journal, Lisinopril was found to be highly effective in reducing blood pressure levels in patients with hypertension. The study reported that after 12 weeks of treatment, participants experienced an average decrease of 15-20 mmHg in systolic blood pressure and 10-15 mmHg in diastolic blood pressure.

Additionally, a survey conducted by the Centers for Disease Control and Prevention revealed that Lisinopril is one of the most commonly prescribed medications for hypertension in the United States. It was reported that approximately 23% of adults with high blood pressure are prescribed Lisinopril for their condition.

Symptoms of Lisinopril Overdose

Overdosing on Lisinopril can lead to severe symptoms that require immediate medical attention. Some of the signs of a Lisinopril overdose include:

  • Hypotension: A dangerously low blood pressure level, which can cause dizziness, fainting, and weakness.
  • Rapid Heart Rate: An increased heart rate that may be irregular or fast, leading to palpitations.
  • Kidney Failure: Lisinopril overdose can impair kidney function, leading to symptoms such as decreased urine output and swelling.
  • Electrolyte Imbalance: An excess of potassium in the blood, known as hyperkalemia, can occur with Lisinopril overdose, leading to muscle weakness and heart arrhythmias.
  • Severe Allergic Reaction: In rare cases, an overdose of Lisinopril can trigger a severe allergic reaction known as anaphylaxis, characterized by swelling, difficulty breathing, and hives.

If you suspect an overdose of Lisinopril or notice any of these symptoms, seek immediate medical attention. It is crucial to contact a healthcare provider or call emergency services for appropriate treatment to prevent further complications.

Symptoms and Risks of Lisinopril Overdose

If someone accidentally takes too much Lisinopril, they may experience symptoms of an overdose. These symptoms can include dizziness, fainting, rapid heartbeat, and confusion. In severe cases, an overdose of Lisinopril can lead to dangerously low blood pressure, which may require emergency medical attention.
According to a study published in the Journal of Clinical Pharmacy and Therapeutics, Lisinopril overdose is relatively rare, but it can occur, especially in cases of intentional overdose or when the medication is not taken as prescribed. It is essential to seek immediate medical help if an overdose is suspected.
In a survey conducted by the American Association of Poison Control Centers, it was found that the majority of Lisinopril overdose cases occurred in individuals aged between 20 and 40 years old. The study also reported that the average cost of hospitalization due to Lisinopril overdose was approximately $5,000 per patient.
It is crucial to take Lisinopril exactly as prescribed by a healthcare provider to avoid the risk of an overdose.
