Medications for depression (MAOIs)
Interaction Rating: Major Do not take this combination.
Brewer's yeast contains a chemical called tyramine. Large amounts of tyramine can cause high blood pressure. But the body naturally breaks down tyramine to get rid of it. This usually prevents the tyramine from causing high blood pressure. Some medications used for depression stop the body from breaking down tyramine. This can cause too much tyramine in the body and dangerously high blood pressure.
Medications for fungal infections (Antifungals)
Interaction Rating: Moderate Be cautious with this combination.
Talk with your health provider.
Brewer's yeast is a fungus. Medications for fungal infections help reduce fungus in and on the body. Taking brewer's yeast with medications for fungal infections can reduce the effectiveness of brewer's yeast.
