Metoprolol is a medicine used to treat high blood pressure, severe chest pain, and lower the risk of repeated heart attacks. It is also administered to patients with heart failure. While metoprolol is an effective medication, it can cause side effects in some individuals. These side effects can vary from person to person and may include dizziness, fatigue, and muscle cramps. In rare cases, metoprolol has been associated with more serious side effects, such as an allergic reaction or anaphylaxis. It is always important to consult a healthcare provider to understand the potential risks and benefits of taking this medication.
| Characteristics | Values |
|---|---|
| Muscle spasms | Metoprolol has been associated with muscle cramps, muscular weakness, and myopathy. |
| Side effects | Metoprolol can cause dizziness, drowsiness, lightheadedness, fainting, decreased alertness, and erectile dysfunction. It may also cause changes in blood sugar levels and increase the risk of hypoglycemia. |
| Allergic reaction | In rare cases, metoprolol can cause a serious allergic reaction (anaphylaxis) with symptoms such as swelling of the lips, mouth, throat, or tongue, fast breathing, wheezing, tightness in the throat, and skin, tongue, or lip discolouration. |
| Respiratory distress | Metoprolol has been linked to respiratory distress in a pediatric patient with a mitochondrial disorder, possibly due to the drug's impact on mitochondrial dysfunction. |
| Mitochondrial dysfunction | Metoprolol may worsen underlying chest wall weakness and contribute to mitochondrial dysfunction by impacting the respiratory electron transport chain and CoQ10 levels. |

What You'll Learn
Metoprolol can cause muscle cramps and spasms
Metoprolol is a medicine used to treat high blood pressure, either alone or in combination with other medications. It is also used to treat severe chest pain and lowers the risk of repeated heart attacks. It is a beta-blocker, a class of drugs that affect the response to nerve impulses in certain parts of the body, such as the heart.
Like all medicines, metoprolol can cause side effects, but many people have no side effects or only minor ones. Common side effects include dizziness, drowsiness, lightheadedness, and fainting, especially when getting up suddenly from a lying or sitting position. It may also cause decreased alertness, so it is important to refrain from driving or operating heavy machinery until you know how this medicine affects you.
In addition to these common side effects, metoprolol has been associated with muscle cramps and spasms. There have been reports of metoprolol-induced arthralgia, or joint pain, which resolved within a few days of discontinuing the medication. Metoprolol has also been linked to mitochondrial dysfunction, which can result in muscle weakness and respiratory distress. In one case, a patient with a mitochondrial disorder developed muscle weakness, generalised fatigue, and muscle cramps after starting a beta-blocker.
It is important to note that side effects may vary depending on the individual and may improve as your body adjusts to the medicine. If you experience any side effects, consult your healthcare provider for advice and guidance.

Mitochondrial dysfunction and muscle weakness
Mitochondria are the organelles responsible for generating the energy required to sustain life and support growth. They are present throughout the body, and their dysfunction can affect any organ, including the brain, heart, skeletal muscle, or respiratory system. Mitochondrial dysfunction can be caused by another disease or condition, such as Alzheimer's disease, Type 1 diabetes, or multiple sclerosis. It can also be caused by genetic mutations.
Mitochondrial disorders that mostly cause muscular problems are called mitochondrial myopathies. These can cause weakness and wasting in the muscles of the face and neck, leading to difficulty swallowing and, in rare cases, slurred speech. Mitochondrial myopathies can also cause muscle weakness in the arms and legs, as well as exercise intolerance, or exertional fatigue. This refers to unusual feelings of exhaustion brought on by physical exertion, which can vary from person to person. In some cases, exercise intolerance can lead to muscle breakdown and protein leakage after exercise.
Mitochondrial dysfunction is also associated with skeletal muscle disorders such as Duchenne muscular dystrophy, cachexia, and sarcopenia. Muscle weakness, muscle pain, and low muscle tone are common symptoms of mitochondrial dysfunction. In children, mitochondrial disorders may cause difficulty in developing certain skills, such as sitting, crawling, or walking. As they get older, they may have problems with speech or learning and may be unable to get around as easily as their peers.
Beta-blockers, including metoprolol, have been identified as mitochondrial-toxic agents, causing a significant impact on patients with mitochondrial dysfunction. In one case, a patient with a mitochondrial disorder developed respiratory distress after being prescribed metoprolol for hypertension. The patient's symptoms improved after discontinuing the medication, suggesting that metoprolol aggravated his mitochondrial dysfunction and worsened his underlying chest wall weakness.

Metoprolol-induced arthralgia
Metoprolol is a medicine that can cause side effects in some individuals. While many people experience no side effects or only minor ones, some people may experience muscle cramps, muscular weakness, and arthralgia.
Arthralgia refers to joint pain, and it can be caused by various drugs, including those from the beta-blocker class, which includes metoprolol. Beta-blockers are known to cause arthralgias and elevate anti-nuclear antibodies. Additionally, they can damage mitochondrial biogenesis, which can lead to further mitochondrial dysfunction, impacting the skeletal muscle and respiratory system.
The exact mechanism by which metoprolol induces arthralgia is not explicitly mentioned in the sources. However, it is worth noting that the side effects of metoprolol can vary depending on the individual, and it is always recommended to consult a healthcare provider to address specific circumstances.
If you are experiencing metoprolol-induced arthralgia or any other side effects, it is important to consult your doctor or healthcare provider. They may provide advice, adjust your medication, or recommend alternative treatments to alleviate the symptoms.

Metoprolol's impact on blood vessels
Metoprolol is a β-adrenergic antagonist, or beta-blocker, that is primarily used to treat hypertension (high blood pressure), angina pectoris, heart failure, and arrhythmias. It lowers blood pressure and slows down the heart rate, making it easier for the heart to pump blood to the rest of the body.
Metoprolol selectively inhibits β-1 adrenergic receptors, which are predominantly found in the heart, and to a lesser extent, the β-2 receptors in the lungs and blood vessels. By blocking the effects of adrenaline on these receptors, metoprolol causes a decrease in cardiac contractility, heart rate, and blood pressure. This can lead to common side effects such as tiredness, dizziness, shortness of breath, and hypotension (low blood pressure).
While metoprolol is generally well-tolerated, it may cause adverse effects in some individuals. These side effects are often mild and may improve as the body adjusts to the medication. However, it is important to monitor blood pressure and heart rate regularly while taking metoprolol, as changes in these parameters can indicate potential issues. Additionally, metoprolol may mask symptoms of hypoglycemia (low blood sugar) and increase the risk of serious or prolonged hypoglycemic episodes, especially in patients with diabetes.
It is important to consult a healthcare provider before taking metoprolol, as they can provide instructions and guidance on its use. They may also advise on potential side effects and how to manage them. Some side effects, such as dizziness and drowsiness, can impact activities like driving or operating machinery. Therefore, it is crucial to understand how metoprolol affects the individual before engaging in such activities.

Metoprolol and fatigue
Metoprolol is a beta-blocker medication that treats high blood pressure and other heart conditions. It is available as immediate-release and extended-release tablets.
Fatigue is a common side effect of metoprolol. This may be due to the drug's ability to slow down the heart rate and lower blood pressure, which can make you sleepy. Metoprolol also passes into the brain, which may be another reason for the tiredness it causes.
It is estimated that around 10 in 100 people who take the immediate-release version (metoprolol tartrate) experience tiredness as a side effect. Tiredness was also reported as a side effect in more than 2% of patients who took the extended-release version (metoprolol succinate) during clinical trials for high blood pressure and angina. In one study, 5% of patients taking doses above 200 mg per day reported feeling tired, compared to about 4% of patients who took 25 mg to 100 mg per day, and 1% of patients who took a placebo.
If you are experiencing fatigue while taking metoprolol, there are some things you can do to help relieve it. Maintaining a regular sleep schedule and getting adequate sleep can help minimize fatigue. Avoiding caffeine in the late afternoon or evening and sticking to a regular bedtime routine can improve your sleep. Regular exercise can also help increase your energy levels.
If fatigue is a persistent or bothersome side effect, check with your healthcare provider. They may adjust your dosage or recommend other ways to manage it.
