Long Term Abuse of Domperidone causing Hyperprolactinemia

MDR Kochs patient on AKT since September 2019 along with proton pump inhibitor+Domperidone sustained release tablets since 9 months twice a day for gastritis and nausea, vomiting. Over a period of time kochs was getting healed however patient started complaining of increase in weight and breast since April 2020 .Patient?s TSH level was 5.63uIU/ml and prolactin level -76.97 ng/ml(normal range forTSH-0.45-4.5 uIU/ml and prolactin level -5.18-26.53 ng/ml ). As a chest physician I started looking for AKT or any other drug induced causes of hyperprolactinemia. Patient refused to stop domperidone and started thyroid supplement.
