Canthaxanthin + Prednisone

At least one FDA label for a product containing Prednisone says to take it with food. If you take Canthaxanthin on an empty stomach out of habit, keep them separate — and take Prednisone with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Prednisone products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

These two come up together because they touch the same health topic — not because they do the same job. Prednisone is a prescription medicine with approved uses on its FDA label. Canthaxanthin is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Prednisone is prescribed for: Prednisone is used as an anti-inflammatory or immunosuppressive medicine (one that lowers immune activity). It treats many conditions across several body systems. Main groups include: Allergic conditions, such as severe allergic rhinitis, atopic dermatitis and drug reactions Joint and autoimmune conditions, such as rheumatoid arthritis and lupus Skin, gut, blood, eye, lung and kidney conditions Hormone (endocrine) conditions, such as adrenal insufficiency Palliative care for certain leukemias and lymphomas Prednisone delayed-release tablets (including Rayos) are also labeled for organ transplant rejection, asthma, COPD flares, and idiopathic pulmonary fibrosis. The standard tablet and solution labels list other uses, such as bursitis, tenosynovitis and severe psoriasis.

Canthaxanthin has been studied for:

• Cancer studied, not established Canthaxanthin has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

  Canthaxanthin for cancer

  Although there has been interest in using oral canthaxanthin for cancer, there is insufficient reliable information about the clinical effects of canthaxanthin for this purpose.

• Psoriasis studied, not established Canthaxanthin has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

  Canthaxanthin for psoriasis

  Oral canthaxanthin has only been evaluated in combination with other ingredients; its effect when used alone is unclear.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Prednisone on your own; if you are taking Canthaxanthin for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Out of every supplement and medication people look up on HelloPharmacist, here is where these two land this week — and which way each has been moving.

Position among everything looked up on this site, not a measure of how commonly either one is used or how important it is. A supplement can climb this list because of a news story. It counts every request to the page, automated ones included, and nothing here identifies anyone.

Natural Medicines records Prednisone as a medicine that can lower these. This is not an interaction with Canthaxanthin — it is a separate effect of the medicine, and it is a reason some people are advised to supplement rather than to avoid one:
