Novel immune-based cancer therapies such as programmed death 1 (PD-1) inhibitors continue to emerge for both curative and palliative intent. Post-market data of PD-1 inhibitors indicate that there are a wide range of side effects associated with these drugs, including ones that have relevance to symptom control and represent a diagnostic challenge at the end of life. We present a case of pembrolizumab-induced hypothyroidism causing extreme fatigue and persistent hypoglycemia.
