Which Steroid Causes Black Fungus?

Black fungus, or mucormycosis, is a rare but serious fungal infection that can affect various parts of the body, including the sinuses, lungs, and brain. It is not caused by steroids themselves but can be associated with their use in certain circumstances, particularly when administered in high doses or for extended periods, as steroids can suppress the immune system.

Mucormycosis is more commonly seen in individuals with weakened immune systems or underlying health conditions, such as uncontrolled diabetes, cancer, organ transplantation, and long-term steroid use, which can increase susceptibility to fungal infections. High-dose corticosteroids, often used to manage severe cases of COVID-19, can further weaken the immune system, potentially increasing the risk of fungal infections like mucormycosis.

It’s important to note that while steroids may be a risk factor, the development of mucormycosis is multifactorial, and other factors, such as local environmental exposure to the fungus, may also contribute to its occurrence.

To mitigate the risk of mucormycosis and other fungal infections, healthcare providers carefully weigh the benefits and risks of using corticosteroids in various medical conditions and closely monitor patients receiving these medications, especially in cases where they may have a weakened immune system. If you are prescribed steroids, it is important to follow your healthcare provider’s guidance and report any concerning symptoms or side effects.
