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 should I discuss with my healthcare provider before taking multivitamin?
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.
How should I take multivitamin?
Use this medication as directed on the label, or as your doctor has prescribed. Do not use
the medication in larger amounts or for longer than recommended.
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.
Take your multivitamin with a full glass of water.
The chewable tablet must be chewed or allowed to dissolve in your mouth before
swallowing.
Measure the liquid form of multivitamins using a special dose-measuring spoon or cup,
not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist where
you can get one.
Liquid multivitamins may sometimes be mixed with water, fruit juice, or infant formula
(but not milk or other dairy products). Follow the directions on the medicine label.
It is important to take multivitamins regularly to get the most benefit.
Store this medication at room temperature away from moisture and heat. Keep the
liquid medicine from freezing.
Store multivitamins in their original container. Storing multivitamins in a glass container
can ruin the medication.
What happens if I miss a dose of multivitamin?
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.
