Vitamin and mineral supplements can interact with certain medications, or affect how
medications work in your body. Before taking a multivitamin, tell your doctor if you also use:
trimethoprim and sulfamethoxazole (Cotrim, Bactrim,
Septra, TMP/SMX); or
an NSAID (non-steroidal anti-inflammatory drug) such as
ibuprofen (Motrin, Advil), naproxen (Aleve, Naprosyn), diclofenac (Cataflam, Voltaren),
etodolac (Lodine), indomethacin (Indocin), ketoprofen (Orudis), and others.
This list is not complete and there may be other medications that can
interact with or be affected by multivitamins. Tell your doctor about all the prescription and
over-the-counter medications you use. This includes vitamins, minerals, herbal products, and
drugs prescribed by other doctors. Do not start using a new medication without telling your
doctor.
Get emergency medical help if you have any of these signs of an allergic
reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
When taken as directed, multivitamins are not expected to cause serious side effects. Less
serious side effects may include:
upset stomach;
headache; or
unusual or unpleasant taste in your mouth.
This is not a complete list of side effects and others may occur. Tell
your doctor about any unusual or bothersome side effect.
