Brand Name: Lopressor, Toprol XL
Generic Name: metoprolol
Drug Class: Thiazide Combos
What is metoprolol (Lopressor, Toprol XL), and what is it used for?
Metoprolol is a beta-blocker (beta-adrenergic blocking agent) used for the treatment of:
- High blood pressure
- Heart pain
- Congestive heart failure
- Abnormal heart rhythms
- Some neurologic conditions.
Metoprolol's off-label use is to prevent migraine headaches.
- Metoprolol is used to treat:
- High blood pressure (hypertension
- Congestive heart failure
- Angina pectoris (heart pain) related to coronary artery disease.
- Metoprolol also is useful in slowing and regulating certain types of abnormally rapid heart rates (tachycardias).
- Other uses for metoprolol include:
- Preventing migraine headaches
- Treatment of hyperthyroidism and certain types of tremors
What are the side effects of metoprolol (Lopressor, Toprol XL)?
Metoprolol is generally well tolerated. Side effects include:
- abdominal cramps,
- memory loss,
- low blood pressure,
- decreased exercise tolerance,
- increased triglycerides,
- cold extremities,
- sore throat, and
- shortness of breath or wheezing.
Possible serious adverse effects include:
- slow heart rate,
- Raynaud's phenomenon,
- hepatitis, and
- increased insulin resistance.
Metoprolol can aggravate breathing difficulties in patients with asthma, chronic bronchitis, or emphysema.
- In patients with existing slow heart rates (bradycardias) and heart blocks (defects in the electrical conduction of the heart), metoprolol can cause dangerously slow heart rates and even shock. Metoprolol reduces the force of heart muscle contraction and can aggravate symptoms of heart failure. In patients with coronary artery disease, abruptly stopping metoprolol can suddenly worsen angina, and occasionally precipitate heart attacks. If it is necessary to discontinue metoprolol, its dosage should be reduced gradually over several weeks.
- Initiation of high-dose extended-release metoprolol in patients undergoing non-cardiac surgery is associated with bradycardia (slow heart rate), hypotension, stroke, and death. However, long-term therapy with metoprolol should not be routinely withdrawn before major surgery. The impaired ability of the heart to respond to reflex adrenergic stimuli may increase the risks of general anesthesia and surgery.
What is the dosage for metoprolol?
- Metoprolol should be taken before meals or at bedtime.
- The dose for treating hypertension is 100-450 mg daily in single or divided doses.
- Angina is treated with 100-400 mg daily in two divided doses.
- Heart attack (acute myocardial infarction) is treated with three 5 mg injections administered 2 minutes apart followed by treatment with 50 mg oral metoprolol every 6 hours for 48 hours. After 48 hours, patients should receive 100 mg orally twice daily for at least 3 months.
- The dose for congestive heart failure is 25 mg/daily initially. Then the dose is increased every 2 weeks to reach a target dose of 200 mg/daily orally.
- Hyperthyroidism is treated with 25 to 30 mg by mouth every 6 hours.
What drugs interact with metoprolol?
- Calcium channel blockers and digoxin (Lanoxin) can lower blood pressure and heart rate to dangerous levels when administered together with metoprolol.
- Metoprolol can mask the early warning symptoms of low blood sugar (hypoglycemia) and should be used with caution in patients receiving diabetes treatment.
- Fluoxetine (Prozac) can increase blood levels of metoprolol by reducing the breakdown of metoprolol and increasing the side effects of metoprolol.
Is metoprolol safe to use during pregnancy or while breastfeeding?
- Safe use of metoprolol during pregnancy has not been established.
- Small quantities of metoprolol are excreted in breast milk and may potentially cause adverse effects in the infant.

Blood Pressure Readings: Chart, Normal, High, Low
Blood pressure is the force applied by the blood over the inner walls of the arteries. Although the average blood pressure for a person remains constant, it shows minor fluctuations throughout the day—declining while relaxing and momentarily increasing while being excited or under stress. An increase in resting blood pressure can scar, stiffen, or harden the arteries.
Why Is My Bottom Blood Pressure Number High?
Isolated diastolic hypertension (IDH) occurs when your systolic blood pressure is normal, and only your diastolic blood pressure is high (over 80 mm Hg). Causes of high diastolic blood pressure include a high-sodium diet, obesity, lack of physical activity, excessive alcohol consumption, stress and anxiety.
High Blood Pressure (Hypertension)
High blood pressure (hypertension) is a disease in which pressure within the arteries of the body is elevated. About 75 million people in the US have hypertension (1 in 3 adults), and only half of them are able to manage it. Many people do not know that they have high blood pressure because it often has no has no warning signs or symptoms. Systolic and diastolic are the two readings in which blood pressure is measured. The American College of Cardiology released new guidelines for high blood pressure in 2017. The guidelines now state that blood normal blood pressure is 120/80 mmHg. If either one of those numbers is higher, you have high blood pressure. The American Academy of Cardiology defines high blood pressure slightly differently. The AAC considers 130/80 mm Hg. or greater (either number) stage 1 hypertension. Stage 2 hypertension is considered 140/90 mm Hg. or greater. If you have high blood pressure you are at risk of developing life threatening diseases like stroke and heart attack.REFERENCE: CDC. High Blood Pressure. Updated: Nov 13, 2017.
How Can I Lower My Blood Pressure in Minutes?
Learn how to lower your high blood pressure quickly and how to better manage this condition.
What Does it Mean When the Bottom Number of Your Blood Pressure is Over 100?
Diastolic blood pressure (DBP) is the pressure exerted on the walls of the arteries when the heart muscle relaxes between beats. When the bottom number of blood pressure (diastole) is over 100 mmHg, it may be called diastolic hypertension (DHT). Diastolic blood pressure means the blood pressure reading during the phase when your heart relaxes (diastole). Force of the blood against the walls of the arteries (the blood vessels carrying blood from the heart to other sites) in the body is called blood pressure. The heart pumps the blood into the arteries as it contracts (systole).
How to Lower My Blood Pressure Immediately
If you face any complications of high blood pressure such as a stroke or heart attack, contact your physician without any delay. Do not attempt home remedies in such grave situations. If you have high blood pressure, without any complications, the first thing to do is to calm down and lie flat.
What Is Considered Stroke-Level High Blood Pressure?
Blood pressure readings above 180/120 mmHg are considered stroke-level and require immediate medical attention. Check out the center below for more medical references on hypertension, including multimedia (slideshows, images, and quizzes), related diseases, treatment, diagnosis, medications, and prevention or wellness.
How Do You Check Your Blood Pressure With Fingers?

Is 120 Over 60 a Good Blood Pressure Reading?
If your systolic blood pressure is normal (between 100-120), and your diastolic blood pressure is lower (60 or below), you are considered to have low blood pressure, or isolated diastolic hypotension. Low diastolic blood pressure should be monitored closely.
Congestive Heart Failure (CHF)
Congestive heart failure (CHF) refers to a condition in which the heart loses the ability to function properly. Heart disease, high blood pressure, diabetes, myocarditis, and cardiomyopathies are just a few potential causes of congestive heart failure. Signs and symptoms of congestive heart failure may include fatigue, breathlessness, palpitations, angina, and edema. Physical examination, patient history, blood tests, and imaging tests are used to diagnose congestive heart failure. Treatment of heart failure consists of lifestyle modification and taking medications to decrease fluid in the body and ease the strain on the heart. The prognosis of a patient with congestive heart failure depends on the stage of the heart failure and the overall condition of the individual.
Raynaud's phenomenon is characterized by a pale-blue-red sequence of color changes of the digits, most commonly after exposure to cold. Occurring as a result of spasms of blood vessels, the cause is unknown. Symptoms and signs of Raynaud's phenomenon depend on the severity, frequency, and duration of the blood vessel spasm. Treatments include protection of the digits, medications, and avoiding emotional stresses, smoking, cold temperature, and tools that vibrate the hands.
What Is the Blood Pressure of a Very Fit Person?
Studies show that a very fit person who exercises regularly will have a lower resting blood pressure (usually below 120/80 mm Hg) than someone who leads a sedentary lifestyle.
Arrhythmias (Abnormal Heart Rhythms)
Heart rhythm disorders vary from minor palpitations, premature atrial contractions (PACs), premature ventricular contractions (PVCs), sinus tachycardia, and sinus bradycardia, to abnormal heart rhythms such as tachycardia, ventricular fibrillation, ventricular flutter, atrial fibrillation, atrial flutter, paroxysmal supraventricular tachycardia (PSVT), Wolf-Parkinson-White syndrome, brachycardia, or heart blocks. Treatment is dependent upon the type of heart rhythm disorder.
Atrial Fibrillation (AFib)
Atrial fibrillation (AF or AFib) is an abnormality in the heart rhythm, which involves irregular and often rapid beating of the heart. Symptoms may include heart palpitations, dizziness, fainting, fatigue, shortness of breath, and chest pain. Atrial fibrillation treatment may include medication or procedures like cardioversion or ablation to normalize the heart rate.
Hyperthyroidism is an excess of thyroid hormone due to an overactive thyroid gland. Symptoms can include increased heart rate, weight loss, heart palpitations, frequent bowel movements, depression, fatigue, fine or brittle hair, sleep problems, thinning skin, and irregular vaginal bleeding. Graves' disease is the most common cause of hyperthyroidism. Many other health problems or taking excess thyroid hormone medication can cause an overactive thyroid gland. Treatment for the condition is with medication, radioactive iodine, thyroid surgery (rarely), or reducing the dose of thyroid hormone. No diet has been shown to treat hyperthyroidism or its symptoms and signs.
Migraine headache is a type of headache associated with a sensitivity to light, smells, or sounds, eye pain, severe pounding on one side of the head, and sometimes nausea and vomiting. The exact cause of migraine headaches is not known. Triggers for migraine headaches include certain foods, stress, hormonal changes, strong stimuli (loud noises), and oversleeping. Treatment guidelines for migraines include medicine, pain management, diet changes, avoiding foods that trigger migraines, staying hydrated, getting adequate sleep, and exercising regularly. Prevention of migraine triggers include getting regular exercise, drinking water daily, reducing stress, and avoiding trigger foods.

Abdominal Aortic Aneurysm
Abdominal aortic aneurysm is a ballooning or widening of the main artery (the aorta) as it courses down through the abdomen. Most abdominal aortic aneurysms produce no symptoms. Treatment may include observation or surgical repair.
Is A Manual Blood Pressure More Accurate?
Manual blood pressure gives accurate results when used correctly by a trained person. However, manual blood pressure measurement is not the recommended type of blood pressure monitoring for home use because it requires some training.
Palpitations are uncomfortable sensations of the heart beating hard, rapidly, or irregularly. Some types of palpitations are benign, while others are more serious. Palpitations are diagnosed by taking the patient history and by performing an EKG or heart monitoring along with blood tests. An electrophysiology study may also be performed. Treatment of palpitations may include lifestyle changes, medication, ablation, or implantation of a pacemaker. The prognosis if palpitations depends on the underlying cause.

Which Blood Pressure Number Is the Most Important?
The blood that flows through the arteries (blood vessels carrying blood from the heart to other parts of the body) exerts pressure against the arterial walls. The number above (120) is called the systolic blood pressure and the number below (80) is called the diastolic blood pressure. Though both readings are important, many doctors believe that systolic blood pressure is a better predictor of complications of hypertension, such as heart disease or stroke.
Pulmonary hypertension is elevated pressure in the pulmonary arteries that carry blood from the lungs to the heart. The most common symptoms are fatigue and difficulty breathing. If the condition goes undiagnosed, more severe symptoms may occur. As pulmonary hypertension worsens, some people with the condition have difficulty performing any activities that require physical exertion. While there is no cure for pulmonary hypertension, it can be managed and treated with medications and supplemental oxygen to increase blood oxygen levels.
Portal hypertension is most commonly caused by cirrhosis, a disease that results from scarring of the liver. Other causes of portal hypertension include blood clots in the portal vein, blockages of the veins that carry the blood from the liver to the heart, and a parasitic infection called schistosomiasis. Symptoms of portal hypertension include varices (enlarged veins), vomiting blood, blood in the stool, black and tarry stool, ascites (abnormal fluid collection within the peritoneum, the sac that contains the intestines within the abdominal cavity), confusion and lethargy, splenomegaly or enlargement of the spleen, and decreased white blood cell counts.
Hypertension-Induced Chronic Kidney Disease
Hypertension-induced chronic kidney disease (CKD) is a long-standing kidney condition that develops over time due to persistent or uncontrolled high blood pressure (hypertension).

Migraine vs. Headache: Differences and Similarities
Headaches are the most common reason why a person goes to the doctor or other healthcare professional for treatment. There are different types of headaches, for example, migraine, tension, and cluster headaches. The most common type of headache is tension headache. Migraine is much less common. There are few similarities between migraine and other headaches, for example, the severity of the pain can be the same, mild, moderate, or severe; and they can occur on one side or both sides of the head. However, there are many differences between migraine and other types of headaches. Migraine headaches also have different names, for example, migraine with aura and menstrual migraine. Symptoms of migraine that usually aren't experienced by a person with another type of headache include nausea, vomiting, worsens with mild exercise, debilitating pain, eye pain, throbbing head pain. Migraine trigger include light, mild exercise, strong smells, certain foods like red wine, aged cheese, smoked meats, artificial sweeteners, chocolate, alcohol, and dairy products, menstrual period, stress, oversleeping, and changes in barometric pressure. Untreated migraine attacks usually last from 4 to 72 hours, but may last for weeks. Most headaches resolve within 24-48 hours. Doctors don't know exactly what causes migraine headaches; however, other headaches like tension headaches have more specific triggers and causes. Additional tests usually are required to diagnose migraine from other types of headaches, diseases, or other medical problems. Most headaches can be treated and cured with home remedies like essential oils, massage, and over-the-counter pain medication like acetaminophen (Tylenol) and NSAIDs (nonsteroidal anti-inflammatory drugs) like naproxen (Aleve, Anaprox, Naprosyn) or ibuprofen (Advil, Midol, Motrin). Most headaches resolve with OTC and home remedy treatment, while your doctor may need to prescribe medication to treat your migraines. If you have the "worst headache of your life," seek medical care immediately.
