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.
What is the most important information I should know about multivitamins?
Never take more than the recommended dose of a multivitamin. 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.
Many multivitamin products also contain minerals such as calcium, iron, magnesium, potassium, and zinc. Minerals (especially taken in large doses) can cause side effects such as tooth staining, increased urination, stomach bleeding, uneven heart rate, confusion, and muscle weakness or limp feeling. Read the label of any multivitamin product you take to make sure you are aware of what it contains.
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.
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.
What should I discuss with my healthcare provider before taking multivitamins?
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.
