What is Neostigmine?

Simply put, Neostigmine is a drug that helps improve the strength of your muscles. Our nerves and muscles communicate through a chemical. In the case of Myasthenia Gravis, this communication does not happen properly. Neostigmine works by making the chemical that carries the message stay there longer, strengthening the connection between the nerves and the muscles. This helps the muscles regain strength and makes it easier to perform daily tasks.

This medicine can sometimes be used for other medical conditions, so if you have any further questions about this, it's best to ask your doctor.
