Let's learn about Amphotericin B, a drug used to treat serious fungal infections.

Sometimes, fungal infections in our bodies can be so serious that they can't be cured with regular pills or creams. These infections can sometimes spread to the bloodstream, lungs, or even the brain. Doctors use this powerful drug called Amphotericin B to control serious, life-threatening fungal infections. This is a drug that is often given intravenously in a hospital, under the direct supervision of a doctor. So today, let's talk about this drug, its possible side effects, and what you need to know as a person receiving this treatment.

What kind of medicine is Amphotericin B?

Simply put, Amphotericin B is an antifungal, meaning it kills fungal cells and controls the infection . But it is not a medicine for a common fungal infection. Because it is so strong, it is mainly used for serious fungal infections that have not responded to other medications and that affect the body's internal organs. You may find this medicine under brand names like `Amphocin` or `Fungizone`.

Your doctor may prescribe this medicine for other reasons as well, so if you have any questions, it's best to ask your doctor about it.
