Possible Interactions with Vitamin B2 (Riboflavin)

Overview

Poor dietary habits in combination with birth control medications can interfere with the body's ability to use riboflavin.

Riboflavin can interfere with antibiotics that are sulfa-containing drugs.

Riboflavin may reduce the effectiveness of medications taken for malaria (such as chloroquine, mesloquine).

Riboflavin interacts with selegiline, a mediation used for Parkinson's disease.

Riboflavin may interact with doxorubicin, a medication used for the treatment of certain cancers.

Methotrexate, a medication used to treat cancer, can prevent the body from making riboflavin (as well as other essential vitamins).

Psychotherapeutic medications called phenothiazines (such as chlorpromazine) may lower riboflavin levels.

Tricyclic antidepressants (imipramine, amitriptyline) inhibit the body's use of riboflavin.
