Vitamin C may interact with certain medications, including aluminum, chemotherapy drugs, estrogen, protease inhibitors, statins, niacin, and warfarin. Vitamin C supplements can decrease the level or effect of omadacycline by inhibition of GI absorption. This applies only to the oral form of both agents. Multivalent cation-containing products may impair absorption of tetracyclines, which may decrease its efficacy.
