How should I use this medication?

The recommended dose of this medication is 1 pink tablet in the morning and 1 blue/dark blue tablet at least 4 hours afterward or in the evening.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

The pink tablets and the blue tablets must be taken separately to prevent the ingredients in one tablet from interacting with the other. When taken at the same time, iron interacts with folic acid and calcium. This prevents the iron from being absorbed into the body where it can be used.

The pink tablets should be taken on an empty stomach with a full glass of water. Wait at least one hour before eating, to allow time for the iron to be absorbed.

The blue tablet should be taken at least 4 hours after the pink tablet. To ensure your body absorbs as much calcium as possible, take it within an hour of the evening meal. The acid from the stomach helps break the calcium down so it can be absorbed.

Swallow the medication whole, with a glass of water. Do not crush or split the tablets.

It is important to take this medication exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store this medication at room temperature, protect it from light and moisture, and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

Who should NOT take this medication?

Do not take this medication if you are allergic to multiple vitamin and minerals or any ingredients of the medication.

Are there any other precautions or warnings for this medication?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Other medications: Many medications are affected by the calcium and iron in these multiple vitamins. Check with your pharmacist for specific instructions about separating your regular medications and this multiple vitamin and mineral supplement.

Seizure: People who have seizure disorder and are taking anticonvulsant medication (e.g., carbamazepine, phenobarbital, phenytoin, primidone, valproic acid) may have an increase in seizures when taking folic acid (one of the vitamins in this medication). If you have seizure disorder and are taking anticonvulsants, talk to your doctor about whether any special monitoring is required.

Vitamin B12: High doses of folic acid may hide symptoms of vitamin B12 deficiency. If you have vitamin B12 deficiency, your doctor may recommend a vitamin B12 supplement along with the folic acid that is in this medication. Your doctor may decide to do blood tests to monitor your vitamin B12 levels.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take.
