Vitamin A and Deferasirox

Here is the interaction we found between these two, with the evidence behind it.

Moderate

HEPATOTOXIC DRUGS

Why this applies to Deferasirox

Deferasirox falls under HEPATOTOXIC DRUGS — the group Vitamin A interacts with.

Theoretically, taking high doses of vitamin A in combination with other potentially hepatotoxic drugs might increase the risk of liver disease.
The tolerable upper intake level (UL) is the highest level of intake that is likely to pose no risk of adverse effects. Doses of vitamin A above the UL can cause hepatotoxicity, ranging from elevated liver enzymes to liver failure.
Severity Moderate Likelihood Possible Evidence C

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the concern with Deferasirox (Exjade, Jadenu): this iron chelator can be tough on your liver on its own, and your care team usually checks liver enzymes while you're on it. High doses of vitamin A can also stress the liver, since too much of this fat-soluble vitamin can build up and raise liver enzymes or, rarely, cause more serious liver trouble. Stacking the two could, in theory, add to that strain.

Keep in mind this is based mostly on expert opinion, not hard studies, and it really applies to high-dose supplements (above the upper limit), not the small amounts in food or a normal multivitamin. Watch for warning signs like yellowing skin or eyes, dark urine, belly pain, or unusual tiredness, and check with your pharmacist or doctor before adding vitamin A.

About Vitamin A

What is Vitamin A?

  • Eye and vision health
  • Skin health and acne
  • Immune support
  • Correcting vitamin A deficiency
  • Childhood growth and development

Vitamin A is an essential nutrient important for vision, skin, immune function, and growth. Most people get enough from a balanced diet, and supplements are mainly useful for correcting a true deficiency. Because vitamin A is fat-soluble and can build up to harmful levels, more is not better, and high doses are especially risky in pregnancy.

About Deferasirox

What Is Deferasirox Used For?

Brand names: Exjade, Jadenu

Deferasirox — available as tablets (film-coated and for oral suspension) and as oral granules, and sold under brand names including Exjade (tablet for oral suspension) and Jadenu (film-coated tablet and granules) — is used to remove excess iron that builds up in the body. All formulations are approved to treat chronic iron overload due to blood transfusions in patients 2 years of age and older.

All formulations are also approved for chronic iron overload in non-transfusion-dependent thalassemia (NTDT) syndromes in patients 10 years of age and older, but only when liver iron levels and serum ferritin meet specific thresholds. Using deferasirox together with other iron-chelation medicines has not been shown to be safe or effective.
