Respiratory symptoms like wheezing or dyspnea may occur, along with mood changes or sleep disturbances. Rare side effects include liver problems and kidney issues.
carries several important warnings. It can cause bradycardia (slow heart rate), hypotension (low blood pressure), and heart failure in some patients, especially in those with pre-existing heart conditions. Respiratory issues such as wheezing may occur, and the drug should be used cautiously in patients with asthma or bronchospastic diseases. Stopping atenolol abruptly can worsen heart conditions, so it must be tapered off gradually. It may also mask symptoms of low blood sugar in diabetic patients.
Overdose, symptoms may include severe bradycardia (extremely slow heart rate), hypotension (low blood pressure), heart failure, shock, seizures, and respiratory depression. Immediate medical attention is required, with treatment focused on supportive care such as IV fluids, atropine for bradycardia, and glucagon for severe heart issues. Overdose may also lead to hypoglycemia in diabetics.
