Beta-blockers are a class of drugs that are commonly prescribed to treat heart and circulatory problems, as well as conditions related to the brain and nervous system. They work by slowing down the heart rate and relaxing smooth muscle tissue in blood vessels, which helps to lower blood pressure. While beta-blockers are generally considered safe, like most medications, they can cause side effects in some individuals. One of the known side effects of beta-blockers is muscle weakness, particularly in individuals with mitochondrial disease or dysfunction. In rare cases, beta-blockers have also been associated with toxic myopathy and rhabdomyolysis, which can lead to generalized muscle weakness and fatigue. Additionally, combining beta-blockers with alcohol or certain other medications can cause a dangerous drop in blood pressure, resulting in dizziness, lightheadedness, and weakness.

Beta-blockers can cause muscle weakness in patients with mitochondrial disease
Beta-blockers are a class of medications commonly used to treat heart and circulatory problems. They are also prescribed for conditions related to the brain and nervous system, such as migraines, anxiety, and glaucoma. Beta-blockers work by slowing down the heart rate and relaxing smooth muscle tissue in blood vessels, thereby lowering blood pressure.
While beta-blockers have been extensively studied and are generally considered safe, like most medications, they can cause side effects. Commonly reported side effects include dizziness, lightheadedness, and fatigue. Beta-blockers may also cause muscle-related issues, such as muscle pain, spasms, and weakness. In rare cases, they have been associated with toxic myopathy and rhabdomyolysis, a serious condition involving the breakdown of muscle fibres.
The impact of beta-blockers on muscle weakness is particularly notable in patients with mitochondrial disease. Mitochondrial disorders are characterised by dysfunction of mitochondria, the organelles responsible for generating energy in the body. This dysfunction can affect various organs, including the brain, heart, skeletal muscle, and respiratory system. Beta-blockers have been identified as mitochondrial-toxic agents, and their use may trigger or aggravate muscle weakness in patients with mitochondrial disease.
A case report describes a paediatric patient with a mitochondrial disorder who developed respiratory distress after being prescribed metoprolol, a beta-blocker, for hypertension. Discontinuation of the medication led to improvement, suggesting that beta-blockers can worsen underlying chest wall weakness in patients with mitochondrial dysfunction. Another case study mentions a 75-year-old woman who experienced generalized weakness after her medication was changed to include nebivolol, a beta-blocker.
Given the potential for beta-blockers to aggravate or trigger muscle weakness in patients with mitochondrial disease, healthcare providers should exercise caution when considering their use in this population. While beta-blockers may be beneficial for managing certain conditions, the risks and benefits must be carefully weighed, especially in individuals with mitochondrial disorders.

Beta-blockers can cause lung muscle spasms, making it difficult to breathe
Beta-blockers are a class of medications commonly used to treat problems with the heart and circulatory system. They can also be used to treat conditions related to the brain and nervous system, such as migraines, anxiety and glaucoma. Beta-blockers work by slowing down the heart rate and relaxing smooth muscle tissue in blood vessels, thereby lowering blood pressure.
Beta-blockers may also interact with other medications, such as alcohol, and cause your blood pressure to drop too quickly, leaving you feeling weak, dizzy or lightheaded. They may also mask the warning signs of low blood sugar in people with diabetes. It is important to discuss all medications and supplements you are taking with your doctor.
In some cases, beta-blockers have been associated with muscle weakness, muscular fatigue and muscle cramps, particularly in patients with mitochondrial disease. Mitochondrial disorders are a group of diseases characterised by dysfunction of the mitochondria, which are responsible for generating the energy required to sustain life and support growth. Mitochondrial dysfunction can affect any organ, including the brain, heart, skeletal muscle and respiratory system. Beta-blockers have been found to damage mitochondrial biogenesis, which can lead to decreased oxygen availability to the muscles, potentially causing muscle weakness.
If you are experiencing any side effects from beta-blockers, it is important to consult your doctor or healthcare provider. They may recommend adjusting the dosage or exploring alternative treatments.
