Central nervous system-related side effects and risks of beta blockers may include fatigue, depression, sleep disorders (namely insomnia) and nightmares, visual hallucinations, delirium, psychosis, Parkinson's disease, and falling.
Several studies have suggested that nebivolol has reduced typical beta-blocker-related side effects, such as fatigue, clinical depression, bradycardia, or impotence. [35] [36] [37] However, according to the FDA [38] Bystolic is associated with a number of serious risks.
Common side effects include feeling tired, heart failure, dizziness, depression, and shortness of breath. Other serious side effects include bronchial spasm. Use is not recommended during pregnancy and alternative drugs are preferred when breastfeeding.
Common side effects include nausea, abdominal pain, and constipation. It may worsen the symptoms of asthma. Propranolol may cause harmful effects for the baby if taken during pregnancy. Its use during breastfeeding is probably safe. It is a non-selective beta blocker which works by blocking β-adrenergic receptors.
Common side effects include headache, feeling tired, diarrhea, and swelling in the legs. More severe side effects include worsening asthma, blocking the ability to recognize low blood sugar, and worsening heart failure. There are concerns that use during pregnancy may be harmful to the baby.
Adverse effects, especially with higher doses, include dizziness, drowsiness, fatigue, diarrhea, unusual dreams, trouble sleeping, depression, and vision problems such as blurred vision or dry eyes. β-blockers, including metoprolol, reduce salivary flow via inhibition of the direct sympathetic innervation of the salivary glands.
It was suspected that propranolol's centrally induced side effects could be due to its high lipophilicity. Thus, it was focused on synthesizing analogues with hydrophilic moieties, favourably placed to see if the side effects would decrease.
An allergy to timolol or any other beta-blockers; Asthma or severe chronic obstructive bronchitis; A slow heart rate (bradycardia), or a heart block; Heart failure; Side effects. The most serious possible side effects include cardiac arrhythmias and severe bronchospasms.
Serious side effects may include low blood pressure, liver problems, heart failure, and bronchospasm. [1] Use appears safe in the latter part of pregnancy and it is not expected to cause problems during breastfeeding. [2] [3] It works by blocking the activation of β- and α-adrenergic receptors.
Other serious side effects may include QT prolongation, heart failure, or bronchospasm. Sotalol is a non-selective β-adrenergic receptor blocker which has both class II and class III antiarrhythmic properties.
