In other controlled trials, dolasetron was tested for use patients for the prevention or treatment of postoperative nausea and vomiting (PONV). For many of the effects listed below, whether the patient received concurrent chemotherapy was not specified in the literature.

Nervous system

Nervous system side effects including headaches (9.4% to 24.3%), lightheadedness (13%), and dizziness (2.2% to 5.5%) have been reported. Flushing, vertigo, paresthesia, and tremor have been reported infrequently. Ataxia and twitching have been reported rarely.
