Dimercaprol, also called British anti-Lewisite (BAL), is a medication used to treat acute poisoning by arsenic, mercury, gold, and lead.[3] It may also be used for antimony, thallium, or bismuth poisoning, although the evidence for those uses is not very strong.[3][4] It is given by injection into a muscle.[3]

Common side effects include high blood pressure, pain at the site of the injection, vomiting, and fever.[3] It is not recommended for people with peanut allergies as it is typically formulated as a suspension in peanut oil.[3] It is unclear if use in pregnancy is safe for the baby.[3] Dimercaprol is a chelator and works by binding with heavy metals.[3] It has a very pungent odor.

Dimercaprol was first made during World War II.[5] It is on the World Health Organization's List of Essential Medicines.[6]
