pamidronate disodium injection Overdosage

OVERDOSAGE

There have been several cases of drug maladministration of intravenous pamidronate disodium in hypercalcemia patients with total doses of 225 mg to 300 mg given over 2½ to 4 days. All of these patients survived, but they experienced hypocalcemia that required intravenous and/or oral administration of calcium. Single doses of pamidronate disodium should not exceed 90 mg and the duration of the intravenous infusion should be no less than 2 hours (See WARNINGS).

In addition, one obese woman (95 kg) who was treated with 285 mg of pamidronate disodium/day for 3 days experienced high fever (39.5°C), hypotension (from 170/90 mmHg to 90/60 mmHg), and transient taste perversion, noted about 6 hours after the first infusion. The fever and hypotension were rapidly corrected with steroids.

If overdosage occurs, symptomatic hypocalcemia could also result; such patients should be treated with short-term intravenous calcium.
