Potential Negative Interaction

  • Vitamin A

    Large amounts of vitamin A can cause side effects, and oral tretinoin can cause similar side effects. Combining vitamin A with oral tretinoin is likely to increase the risk of side effects. People taking oral tretinoin should probably not take more than 10,000 IU of supplemental vitamin A per day.

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