Lipoflavonoids are multivitamins. Multivitamins are designed to take up the slack, to provide the vitamins and minerals you might miss if you don't always eat balanced, nutritious meals. There is some controversy over their effectiveness and a consideration that they might actually be harmful, according to the Mayo Clinic. "[It is] alarming to think that vitamin or mineral supplements could actually cause more harm than good," Mayo Clinic nutritionists say.
Allergic Reactions
Lipoflavonoids may cause allergic reactions in some people. These may include throat swelling, tongue swelling, facial swelling, lip swelling, breathing difficulties or hives. All of these require emergency medical treatment. These side effects are uncommon, but should not be taken lightly if even one of them occurs while you are taking multivitamins.
Typical Side Effects
Lipoflavonoids may cause low-key side effects that do not require emergency medical treatment. These side effects, if they occur, may require that you decide if you want to continue taking a multivitamin. They also may fade and go away. These side effects may include having an unpleasant taste in the mouth, nausea and headaches.
Drug Interactions
Lipoflavonoids may interact with medications you are taking. You should consult your doctor before starting a multivitamin if you take one or more of several medications. Nonsteroidal anti-inflammatory drugs (NSAIDs) include such over-the-counter medications as ibuprofen and naproxen sodium. Prescription-level NSAIDs such as diclofenac and etodolac also require a doctor's consent for lipoflavonoids. Indomethacin, a medication often prescribed for gout or arthritis, also may cause problems. Blood pressure medications, heart medications and diuretics also may cause unfavorable interactions with multivitamins.
