1 What is Anthrasil?

Brand: Anthrasil

Generic: Anthrax Immune Globulin

Anthrax immune globulin belongs to a group of medicines known as immunizing agents. It is often used in combination with antibiotics to treat a serious disease termed as anthrax which is spread by touching or eating something that is infected with the anthrax germ, such as animals, or by breathing in the anthrax germ i.e. Bacillus anthracis.

This product is available in solution form which is given to the patients only by or under the supervision of a doctor or other trained healthcare professionals.
