What is multivitamin?

Multivitamins are a combination of many different vitamins that are normally found in foods and other natural sources.

Multivitamins are used to provide vitamins that are not taken in through the diet. Multivitamins are also used to treat vitamin deficiencies (lack of vitamins) caused by illness, pregnancy, poor nutrition, digestive disorders, and many other conditions.

Multivitamins may also be used for other purposes not listed in this medication guide.


Many vitamins can cause serious or life-threatening side effects if taken in large doses. Do not take more of this medication than directed on the label or prescribed by your doctor.

If you have any medical conditions, ask your doctor before taking a multivitamin. If you have certain conditions, you may need a certain vitamin formulation or special tests while taking a multivitamin.

Do not take multivitamins without telling your doctor if you are pregnant or plan to become pregnant. Some vitamins and minerals can harm an unborn baby if taken in large doses. You may need to use a prenatal vitamin specially formulated for pregnant women.

Multivitamins can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.

Avoid taking more than one multivitamin product at the same time unless your doctor tells you to. Taking similar vitamin products together can result in a vitamin overdose or serious side effects.

Avoid the regular use of salt substitutes in your diet if your multivitamin contains potassium. If you are on a low-salt diet, ask your doctor before taking a vitamin or mineral supplement.

Do not take this medication with milk, other dairy products, calcium supplements, or antacids that contain calcium. Calcium may make it harder for your body to absorb certain ingredients of the multivitamin.

Seek emergency medical attention if you think you have used too much of this medicine. An overdose of vitamins A, D, E, or K can cause serious or life-threatening side effects. Certain minerals contained in a multivitamin may also cause serious overdose symptoms if you take too much.

Overdose symptoms may include stomach pain, vomiting, diarrhea, constipation, loss of appetite, hair loss, peeling skin, tingly feeling in or around your mouth, changes in menstrual periods, weight loss, severe headache, muscle or joint pain, severe back pain, blood in your urine, pale skin, and easy bruising or bleeding.

Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and take the medicine at the next regularly scheduled time. Do not take extra medicine to make up the missed dose.

Side effects

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. You may report side effects to FDA at 1-800-FDA-1088.

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:

  • diuretics (water pills);
  • heart or blood pressure medications;
  • tretinoin (Vesanoid);
  • isotretinoin (Accutane, Amnesteen, Clavaris, Sotret);
  • 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.
