Summary of Interactions with Vitamins, Herbs, & Foods

Types of interactions: Beneficial Adverse Check

Replenish Depleted Nutrients

  • none

Reduce Side Effects

  • Vitamin E

    Preliminary research has found that combined administration of isotretinoin and vitamin E (alpha-tocopherol) substantially reduces the initial toxicity of high-dose isotretinoin without reducing drug efficacy.1 Additional research is needed to further clarify this potentially beneficial interaction.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.

Support Medicine

  • none

Reduces Effectiveness

  • none

Potential Negative Interaction

  • Vitamin A

    Although little is known about how isotretinoin interacts with real vitamin A, the two are structurally similar and have similar toxicities. Therefore, people taking isotretinoin should avoid vitamin A supplements at levels higher than typically found in a multivitamin (10,000 IU per day).
