Common side effects include gastrointestinal upset and gout.[3] Serious side effects may include liver problems, pancreatitis, and psychosis.[3] Use is not recommended during pregnancy.[3] Use during breastfeeding may harm the baby.[2] Atenolol works by blocking β1-adrenergic receptors in the heart, thus decreasing the heart rate and workload.[3] Chlorthalidone works by increasing the amount of sodium lost by the kidneys.[2]
The combination was approved for medical use in the United States in 1984.[4] It is available as a generic medication.[3] In 2017, it was the 304th most commonly prescribed medication in the United States, with more than 1 million prescriptions.[6]
