Interaction Details
Prednisone is classified as belonging to the following category: Cytochrome P450 3A4 (Cyp3A4) Inhibitors
Theoretically, CYP3A4 inhibitors might increase the levels and adverse effects of yohimbine, a constituent of yohimbe bark.
In vitro and clinical research shows that the yohimbe bark constituent, yohimbine, is metabolized by CYP3A4 enzymes. Theoretically, drugs that inhibit CYP3A4 might increase the levels and adverse effects of yohimbine.

Yohimbe Overview
Yohimbe is an evergreen tree native to western Africa. The bark of the tree contains a chemical called yohimbine in concentrations ranging from 0.6-1.38%, which has been used in traditional medicine as a natural aphrodisiac and sexual performance enhancer. While widely available as a dietary supplement, yohimbe should be used with caution, as it can have side effects, such as dizziness, increased blood pressure and rapid heart rate.
Prednisone Overview
-
Prednisone is used alone or with other medications to treat the symptoms of low corticosteroid levels (lack of certain substances that are usually produced by the body and are needed for normal body functioning). Prednisone is also used to treat other conditions in patients with normal corticosteroid levels. These conditions include certain types of arthritis; severe allergic reactions; multiple sclerosis (a disease in which the nerves do not function properly); lupus (a disease in which the body attacks many of its own organs); and certain conditions that affect the lungs, skin, eyes, kidneys blood, thyroid, stomach, and intestines. Prednisone is also sometimes used to treat the symptoms of certain types of cancer. Prednisone is in a class of medications called corticosteroids. It works to treat patients with low levels of corticosteroids by replacing steroids that are normally produced naturally by the body. It works to treat other conditions by reducing swelling and redness and by changing the way the immune system works.
