AND PRECAUTIONS Heart Failure : Was reported more commonly in ZINPLAVA-treated patients with a history of congestive heart failure (CHF) in Trial 1 and Trial 2. In patients with a history of CHF, ZINPLAVA should be reserved for use when the benefit outweighs the risk. ( 5.1 )

5.1 Heart Failure Heart failure was reported more commonly in Trial 1 and Trial 2 in ZINPLAVA-treated patients compared to placebo-treated patients. These adverse reactions occurred primarily in patients with underlying congestive heart failure (CHF). In patients with a history of CHF, 12.7% (15/118) of ZINPLAVA-treated patients and 4.8% (5/104) of placebo-treated patients had the serious adverse reaction of heart failure during the 12-week study period <span class="opacity-50 text-xs">[see Adverse Reactions (6.1) ]</span> . Additionally, in patients with a history of CHF, there were more deaths in ZINPLAVA-treated patients, 19.5% (23/118) than in placebo-treated patients, 12.5% (13/104) during the 12-week study period. The causes of death varied and included cardiac failure, infections, and respiratory failure. In patients with a history of CHF, ZINPLAVA should be reserved for use when the benefit outweighs the risk.
