Ferric subsulfate solution

Ferric Subsulfate Solution is a topical hemostatic agent, often used in medical and dental procedures to control bleeding. It is also known as Monsel's Solution after the French physician Leon Monsel who first prepared it in 1857.

Composition

Ferric subsulfate solution is a complex, basic iron (III) salt of sulfuric acid. It is composed of ferric ions (Fe3+) and sulfate ions (SO4 2-). The solution is typically prepared by reacting iron with sulfuric acid, followed by oxidation of the resulting ferrous sulfate.

Uses

Ferric subsulfate solution is primarily used as a hemostatic agent. It works by causing protein in the blood to coagulate, forming a scab and sealing off the blood vessel. This stops the bleeding and allows the wound to heal. It is commonly used in minor surgical procedures such as biopsy, dental procedures, and in the treatment of cervical dysplasia.

Safety and Precautions

While ferric subsulfate solution is generally safe for topical use, it can cause skin irritation and should not be used on large wounds or deep puncture wounds. It should also not be used in patients with known hypersensitivity to iron or sulfur compounds.
