Interaction Details
Prednisone is classified as belonging to the following category: Cytochrome P450 3A4 (Cyp3A4) Substrates
In vitro research suggests that calamus inhibits cytochrome P450 3A4 (CYP3A4). Theoretically, use of calamus with drugs metabolized by CYP3A4 might increase drug levels and potentially increase the risk of adverse effects.
Some drugs metabolized by CYP3A4 include lovastatin (Mevacor), clarithromycin (Biaxin), indinavir (Crixivan), sildenafil (Viagra), triazolam (Halcion), and numerous others.

Calamus Overview
Calamus is a grass-like plant commonly mostly commonly found in Eastern Europe in swamps or along the banks of waterways. Calamus has traditionally been used in both Ayurdevic and Chinese medicine for a number of ailments, including digestive disorders including colic, ulcers, gastritis, flatulence, diarrhea, intestinal infections, dyspepsia, and anorexia. It is also used to induce vomiting, induce sweating, improve memory and for the treatment of inflammatory disorders. The FDA does not allow calamus in food due research showing it has carcinogenic effects, likely due to the beta-asarone content, which can vary heavily depending on the species.
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.
