Centrum (Multi Vitamins) at CanadaPharmacyOnline.com

Centrum (multivitamins) is a registered consumer health supplement brand. It is currently owned and marketed by Haleon Group, which was previously GSK's Consumer Healthcare division. Centrum products are sold globally, including in Canada.

There are no generic versions explicitly labeled "generic Centrum", but we offer several store-brand or private-label multivitamin supplements that contain a similar blend of vitamins and minerals.

Dosage:

Brand-name Centrum is available as an oral tablet in the following formulations, strengths, and sizes.
• Centrum Select Chewable 60, tablets
• Centrum Performance, 75 tablets
• Centrum Men 50+, 90 tablets
• Centrum Women 90, tablets

• Centrum Forte Essentials, 100 tablets

• Centrum Select Essentials, 250 tablets

Centrum may also offer many products in other forms that are not included in our list.

Centrum supplements are typically taken once daily, as directed on the product label. Patients should consult their doctor or pharmacist to ensure the product is appropriate for their individual health status and to check for potential interactions with other medications.

Usage:

Centrum is a daily multivitamin and multimineral supplement primarily used to fill nutritional gaps in the diet, ensuring the body consistently receives essential micronutrients needed for good health. While it supports overall well-being, immunity, energy, and the health of specific systems like bones and eyes, it is especially essential when a person's diet is limited or insufficient, or when underlying health conditions or life stages, such as aging or pregnancy, increase nutrient needs. It is not a substitute for healthy food. It should be taken as directed, usually once daily with food, after consulting a healthcare provider to confirm it is suitable for your specific health needs and current medications.

Mechanism of Action
Centrum's mechanism of action differs from that of a drug; instead, it involves nutritional replenishment and support. The product provides essential vitamins and minerals that function as cofactors and coenzymes—meaning they are crucial helper molecules that enable thousands of the body's natural enzymes to work correctly. These enzymes are responsible for vital processes, including converting food into energy (metabolism), building and maintaining tissues, and supporting immune and nerve function. By supplying an adequate amount of these micronutrients, Centrum helps support the body's biological system, preventing deficiencies and allowing normal, healthy physiological processes to operate efficiently.

Take Centrum exactly as recommended by your healthcare provider and follow the directions on the product information from Canada.ca. It is typically taken once daily with food.

Consult your doctor or pharmacist for personalized guidance to confirm it is suitable for your specific health needs.

The information below summarizes some, but not all, potential side effects, risks, and interactions. Before starting Centrum, it is essential to discuss all possible side effects, risks, and interactions with your doctor or pharmacist.

Side Effects:

The information below outlines potential side effects of Centrum, but others are possible. Contact your doctor promptly if any side effects are persistent, worsening, or concerning, or if you experience any other concerning symptoms.

Common side effects – These are common side effects of Centrum, but others are possible. Contact your doctor promptly if any side effects are persistent, worsening, or concerning, or if you experience any other concerning symptoms.
• Constipation
• Diarrhea
• Unpleasant taste in the mouth
• Upset stomach or nausea

Note: If your Centrum contains iron, it may cause your stools to turn a dark or black color, which is generally harmless. Also, the B vitamins (especially B2/riboflavin) often cause bright yellow/green urine. Taking the supplement with food can help mitigate gastrointestinal side effects.

Other Potential Side Effects (less common):
• Belly pain/stomach cramps
• Headache

Serious Side Effects: Seek immediate medical attention or call emergency services if you experience any of the following symptoms.
• Allergic reaction (signs may include rash, itching, hives, swelling of the face, tongue, or throat, difficulty breathing, or swallowing)
• Signs of iron overdose (which can be life-threatening, especially in children, and may include fever, severe stomach pain, throwing up blood or material that looks like coffee grounds, or black, tarry, or bloody stools)
• Symptoms of Chronic Excessive Intake (Hypervitaminosis): While rare when taken as directed, excessive long-term use of certain vitamins can lead to symptoms like changes in mental/mood state, unusual weakness, or bone pain.

Contraindications:

The following is not an exhaustive list of contraindications. Before starting Centrum, it is crucial to discuss all your medical conditions, past and present, and all medications you are taking with your doctor or pharmacist.

You should not take Centrum if you have any of the following conditions, as they present a direct health risk:
• Hypersensitivity: You have a known allergy or hypersensitivity to any of the ingredients (including inactive ingredients in the tablet formulation).
• Iron Overload: You have an iron overload disorder, such as hemochromatosis or hemosiderosis.
• Pre-existing Excessive Vitamin Levels: You have hypervitaminosis (pre-existing excessive levels of any fat-soluble vitamin contained in the supplement).

It is crucial to tell your healthcare provider (doctor or pharmacist) about all of your medical conditions, past and present, before starting Centrum. This ensures the supplement's safety and appropriateness for your specific health needs.

These conditions may include, but are not limited to:
• Alcohol Use: Alcohol use or abuse history (which can affect the absorption and metabolism of many nutrients).
• Kidney Disease: Kidney disease, as some vitamin/mineral levels (especially fat-soluble vitamins or potassium) may need adjustment due to reduced kidney function.
• Liver Problems
• Stomach or Intestinal Issues: Stomach or intestinal problems, such as ulcers, celiac disease, or colitis, which can affect nutrient absorption.
• Vitamin B12 Deficiency: Pre-existing Vitamin B12 deficiency (pernicious anemia), as the folic acid in the multivitamin can potentially mask the diagnosis of this condition, which could lead to severe and potentially irreversible neurological damage if not treated promptly.

Drug Interactions:

Before taking the Centrum supplement, it is essential to discuss all potential risks and interactions with your doctor or pharmacist. For complete and up-to-date information, please refer to the consumer label or the Haleon professional health partner website at https://www.haleonhealthpartner-gne.com/content/dam/cf-consumer-healthcare/health-professionals/en_AE/pdf/PIL-Centrum-SILVER_100_ct_Carton.pdf.

Provide your doctor with a complete list of all your medications, including prescriptions, over-the-counter drugs, vitamins, and herbal supplements. Centrum supplement may interact with the following groups of medications:

Significant Drug Interactions (Requires Dose Separation)
• Antibiotics (Tetracyclines and Quinolones): Iron, Calcium, and Zinc in the multivitamin bind to the antibiotic, preventing the body from absorbing the drug, making it less effective. Separate the multivitamin and antibiotic doses by 2 to 6 hours.
• Bisphosphonates (for Osteoporosis): Minerals (especially Calcium) can bind to and reduce the absorption of the bisphosphonate medication. Separate doses by several hours.
• Levodopa (for Parkinson's Disease): Iron can reduce the absorption of levodopa, making it less effective. Separate doses by as much time as possible (ideally 4 hours).
• Minerals (Calcium, Magnesium) in the antacid can also interfere with other medications, requiring separation.
• Thyroid Hormones: Calcium and Iron can block the absorption of levothyroxine, making the thyroid replacement therapy less effective. Separate doses by at least 4 hours.

Interactions Affecting Blood Clotting
• Blood Thinners (Anticoagulants, especially Warfarin): Centrum products typically contain Vitamin K, which promotes blood clotting and can counteract the effects of Warfarin. It is critical to maintain a consistent intake of Vitamin K and to consult your doctor before starting or stopping Centrum.
• Vitamin B12 / High-Dose Vitamin C: While some older studies suggested that high amounts of Vitamin C could affect Vitamin B12 stability, current evidence from clinical studies does not generally support the need to separate their intake strictly. However, if you are concerned, consult your doctor or pharmacist about the optimal timing for your supplements.

Pregnancy and Breastfeeding

For safety and medical accuracy, standard Centrum multivitamins are generally not recommended during pregnancy or breastfeeding. This is primarily because standard adult formulations may provide excessive amounts of preformed Vitamin A (retinol/retinyl esters), which is known to be harmful to a developing fetus and can potentially cause birth defects. Additionally, standard multivitamins usually do not meet the significantly increased nutrient requirements of pregnancy.

Instead, women who are pregnant or breastfeeding should choose a specialized product, such as a Centrum Prenatal or Postnatal formula. These supplements are explicitly designed with:
• Safe levels of Vitamin A (often relying on safer Beta-Carotene).
• Adequate amounts of essential nutrients like Folic Acid (to prevent neural tube defects), Iron (to support increased maternal blood volume), and often DHA (an Omega-3 fatty acid crucial for fetal and infant brain and eye development).

Always consult your healthcare provider (e.g., obstetrician, midwife, or pharmacist) to determine the appropriate supplement, as your nutritional needs change significantly throughout pregnancy and lactation.

Children and Centrum Safety

Centrum is only safe for children when using the age-appropriate "Centrum Junior" or "Centrum Kids" formulations, which are generally designed for children aged 4 to 13 and must be given exactly as directed on the packaging.

WARNING: Adult multivitamins (including Prenatal formulas) are medically unsafe for children. The higher levels of vitamins and minerals, especially Iron, can cause severe systemic toxicity and even death if accidentally ingested by a child. Since accidental overdose of iron-based products is a leading cause of fatal poisoning in children under six, all multivitamin and iron supplements must be stored securely out of their sight and reach.

It is also recommended to consult a pediatrician or family doctor to determine if vitamin supplementation is truly needed and to confirm the correct dosage for a child.
