How should I take multivitamins?

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?


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.

What happens if I overdose?

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.

What should I avoid while taking multivitamins?

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.

What are the possible side effects of multivitamins?

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.
