Vaprisol
The most common adverse reactions reported with Vaprisol administration were infusion site reactions. In studies in patients and healthy volunteers, infusion site reactions occurred in 52.5% of subjects treated with Vaprisol 40 mg/day compared to 3.3% in the placebo group. The majority of the reactions were mild and did not lead to discontinuation of drug. However, some serious infusion site reactions did occur, and infusion site reactions were the most common type of adverse event leading to discontinuation of Vaprisol.
The adverse reactions presented in Table 5 are derived from 72 healthy volunteers and 111 patients with euvolemic hyponatremia who received Vaprisol 20 mg IV as a loading dose followed by 40 mg/day IV for 2 to 4 days and from 40 healthy volunteers and 21 patients with euvolemic hyponatremia who received placebo. The adverse reactions occurred in at least 2% of patients treated with Vaprisol and at a higher incidence for Vaprisol-treated patients than for placebo-treated patients.
