Lisinopril is a commonly prescribed medication used to treat high blood pressure and heart failure. It is also used to improve heart function and reduce the risk of heart attack and stroke. While Lisinopril is a beneficial medication for many, it can cause side effects that range from mild to severe. Some of the more common side effects include dizziness, headache, low blood pressure, and coughing. One of the more serious side effects of Lisinopril is hyperkalemia, or high potassium levels in the blood, which can lead to muscle weakness, pain, and cramps. This is especially true for those with kidney problems, diabetes, or those taking certain other medications.

What You'll Learn
Lisinopril and high potassium levels (hyperkalemia)
Lisinopril is a medication used to treat hypertension (high blood pressure) and heart failure. It works by blocking the formation of angiotensin II, a hormone that causes blood vessels to constrict. By inhibiting the production of this hormone, lisinopril helps blood vessels relax, allowing blood to flow more easily. This leads to a reduction in blood pressure and a decreased risk of heart attack and stroke.
One of the potential side effects of taking lisinopril is hyperkalemia, or high potassium levels in the blood. Hyperkalemia can be a serious condition, and if left untreated, it may lead to death. Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor, and medications in this class have been associated with raising potassium levels. In fact, a study of 5,171 patients starting lisinopril found that 145 experienced hyperkalemia within the first 90 days, resulting in a 2.8% risk.
The risk of developing hyperkalemia while taking lisinopril is influenced by several factors. These include age, kidney function, diabetes status, heart failure, and the dosage of the medication. People with kidney problems, diabetes, or those taking other medications that increase potassium are at a higher risk of developing hyperkalemia. Additionally, the use of potassium supplements and potassium-sparing diuretics can further elevate potassium levels in the blood.
It is important to be vigilant for signs and symptoms of hyperkalemia while taking lisinopril. Common symptoms include muscle weakness, tingling sensations, nausea, vomiting, and confusion. In more severe cases, individuals may experience heart palpitations, shortness of breath, chest pain, and irregular heart rhythms. If you experience any of these symptoms, it is crucial to seek immediate medical attention and contact your healthcare provider. They may adjust your medication regimen or recommend additional monitoring to manage your potassium levels effectively.

Muscle weakness and other symptoms
Lisinopril is a medication used to treat high blood pressure and heart failure. It is also used to improve survival rates in patients with heart problems. While it is a commonly prescribed medication, it can cause a range of side effects, from mild to severe.
Lisinopril can cause muscle weakness, which is a symptom of hyperkalemia or high potassium levels in the blood. Other symptoms of hyperkalemia include nausea, numbness and tingling, chest pain, irregular heartbeat, and muscle cramps or pain. People with kidney problems, diabetes, or those taking certain medications are at a higher risk of developing hyperkalemia. If left untreated, hyperkalemia can lead to serious heart problems and even death.
In addition to muscle weakness, other common side effects of lisinopril include dizziness, lightheadedness, headache, fatigue, nausea, and vomiting. Some people may also experience a dry cough, which usually goes away a few weeks to a few months after starting the medication.
More serious side effects of lisinopril include liver damage, allergic reactions such as angioedema (swelling under the skin), and anaphylaxis. Liver damage symptoms may include jaundice, dark urine, severe stomach pain, and persistent nausea or vomiting. Angioedema can be life-threatening if it causes airway blockage, while anaphylaxis requires immediate medical attention as it can be fatal.
It is important to note that not everyone taking lisinopril will experience the same side effects, and the severity of side effects can vary depending on the individual and the dosage. Regular monitoring and open communication with a healthcare provider are crucial to managing side effects and ensuring the benefits of the medication outweigh the risks.

Side effects: mild to serious
Lisinopril is a commonly prescribed medication used to treat high blood pressure and heart failure. It can also be used to improve a patient's survival rate after a heart attack. While it is a beneficial drug, it does have some side effects, ranging from mild to serious.
Mild Side Effects
Most of the mild side effects of Lisinopril are common to many medications, such as headaches and dizziness. These side effects are usually temporary and tend to get better with continued treatment or soon after stopping the medication. Other mild side effects include:
- Dry cough
- Fatigue
- Nausea
- Diarrhea
- Vomiting
- Low blood pressure
- Mood changes
- Changes in taste
Serious Side Effects
Serious side effects are less common but can be life-threatening and may require immediate medical attention. These include:
- Swelling (Angioedema): Angioedema is a severe allergic reaction that causes swelling under the skin, particularly of the face, lips, tongue, throat, or extremities. It can be dangerous as it may block airways and cause death by asphyxiation.
- High Potassium Levels (Hyperkalemia): Lisinopril can cause an increase in blood potassium levels, leading to symptoms such as muscle weakness, slow or irregular heartbeat, nausea, and fatigue. In severe cases, hyperkalemia can lead to serious heart problems.
- Allergic Reactions: Lisinopril may cause severe allergic reactions, including anaphylaxis, which requires immediate medical attention. Symptoms can include difficulty breathing, swelling of the face and throat, and severe hives.
- Liver Problems: Although rare, Lisinopril can cause liver damage (hepatotoxicity), with symptoms such as jaundice, dark urine, severe stomach pain, and persistent nausea or vomiting.
- Neutropenia: Lisinopril may cause low levels of a type of white blood cell called neutrophils, which help prevent infection. Having low neutrophil levels can increase the risk of infection.

Lisinopril and liver damage
Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor that has been on the market for over 25 years. It is used in the therapy of hypertension and heart failure. While ACE inhibitors are usually well-tolerated, lisinopril has been associated with rare instances of acute liver injury that can be severe and even fatal.
Lisinopril has been linked to a low rate of serum aminotransferase elevations (2%) that was no higher than with placebo therapy in controlled trials. These elevations were transient and rarely required dose modification. Despite its widespread use, fewer than a dozen cases of clinically apparent acute liver injury attributed to lisinopril therapy have been published. The latency to onset has ranged from 2 to 48 weeks, and the pattern of serum enzyme elevations has been hepatocellular.
Several cases of lisinopril-induced liver injury have been reported in the literature. One case involved a 59-year-old woman with type 2 diabetes, a high body mass index, and hypertension who presented with a 5-week history of jaundice and itching. She had no previous or family history of liver problems and had started taking lisinopril for diabetic nephropathy 8 weeks before admission. Another case involved a 55-year-old man who developed jaundice 2 weeks after switching to lisinopril. He had no history of liver disease, alcohol abuse, or risk factors for viral hepatitis.
Lisinopril-induced liver injury is considered idiosyncratic and likely due to a reaction to a minor metabolite. Most instances of acute liver injury reported with lisinopril use have been self-limited, but there have been rare reports of acute liver failure and death. Patients with severe lisinopril-induced acute liver injury should avoid using other ACE inhibitors, although cross-sensitivity to liver injury among these agents is rare.
It is important to note that side effects of any medication may be underreported. If you experience any signs or symptoms of liver damage, such as upper stomach pain, pale stools, dark urine, loss of appetite, nausea, unusual tiredness, or yellow eyes or skin, seek medical attention immediately.

Allergic reactions and angioedema
Lisinopril may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and requires immediate medical attention. Symptoms of an allergic reaction include a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of the hands, face, mouth, or throat. Lisinopril has also been associated with angioedema, a type of swelling that can be life-threatening. Angioedema is characterised by swelling of the deep dermis, subcutaneous, or submucosal tissue, caused by the vascular extravasation of fluid into the interstitium. This can lead to potentially life-threatening airway compromise.
Angioedema associated with ACE inhibitors is well-documented in the literature, and with the increased prescribing of newer, longer-acting agents, this potentially lethal adverse reaction is of even greater concern. Lisinopril is one of the most common medications known to cause angioedema, along with other ACE inhibitors such as enalapril and ramipril. In addition to these demographic factors, certain medical conditions and histories can also increase the likelihood of experiencing angioedema. For example, a history of drug rash, adverse drug reactions, or angioedema can predispose an individual to ACE inhibitor-associated angioedema. Seasonal allergies, which can trigger hypersensitivity reactions, can also contribute to the risk.
While any individual taking ACE inhibitors can develop angioedema, certain factors increase the risk. Studies have shown that individuals of African descent, particularly African Americans, are at a higher risk for developing ACE inhibitor-induced angioedema. This risk is also elevated in women, smokers, and people over the age of 65. Combining lisinopril with certain other drugs can also raise the risk of angioedema. For example, combining it with immunosuppressants or drugs for advanced kidney cancer can increase the risk. Diabetes medications can also interact with lisinopril, increasing the risk of hypoglycaemia and potentially affecting the incidence of angioedema.
The symptoms of angioedema can be similar to those of an allergic reaction, and it can be challenging to determine that ACE inhibitors are the cause. Angioedema typically occurs without itching or hives, which are common in allergic reactions. However, other types of angioedema can be quite itchy and may present with a pronounced rash. Angioedema is often characterised by sudden puffiness in the lips, face, tongue, or throat. In severe cases, it can affect the airways, leading to potentially life-threatening airway blockage. If you experience any unusual swelling while taking lisinopril, contact your doctor right away or seek emergency medical attention if the swelling is severe.
