Dimercaprol (BAL) is used in treating intoxications caused by arsenical compounds. It is occasionally used for lead, mercury and gold intoxication.
Storage/Stability: Dimercaprol injection should be stored below 40°C; preferably at room temperature (15-30°C).
Caution: Dimercaprol is contraindicated in patients with impaired hepatic function, unless secondary to acute arsenic toxicity. The drug is also contraindicated in iron, cadmium, and selenium poisoning as the chelated complex can be more toxic than the metal alone. Because dimercaprol is potentially nephrotoxic, it should be used cautiously in patients with impaired renal function.
