Cases of overdosage with viloxazine hydrochloride (Vivalan)

Twelve cases of viloxazine overdosage are reported. All patients recovered without sequelae and no ECG abnormalities were observed. Gastric lavage was performed in most cases and was probably beneficial. As viloxazine is rapidly absorbed (Bayliss & Case 1975, Case & Reeves 1975) lavage should be carried out as soon as possible after the tablets are taken. Since the drug is almost exclusively excreted in the urine, it is suggested that forced diuresis be carried out to reduce blood levels as quickly as possible.
