Brand Names

In the U.S.-

  • Biamine

In Canada-

  • Betaxin
  • Bewon

Category

  • Nutritional supplement, vitamin

Description

Vitamins (VYE-ta-mins) are compounds that you must have for growth and health. They are needed in small amounts only and are usually available in the foods that you eat. Thiamine (THYE-a-min) (vitamin B 1) is needed for the breakdown of carbohydrates.

Some conditions may increase your need for thiamine. These include:

  • Alcoholism
  • Burns
  • Diarrhea (continuing)
  • Fever (continuing)
  • Illness (continuing)
  • Intestinal disease
  • Liver disease
  • Overactive thyroid
  • Stress (continuing)
  • Surgical removal of stomach

Also, the following groups of people may have a deficiency of thiamine:

  • Patients using an artificial kidney (on hemodialysis)
  • Individuals who do heavy manual labor on a daily basis

Increased need for thiamine should be determined by your health care professional.

Lack of thiamine may lead to a condition called beriberi. Signs of beriberi include loss of appetite, constipation, muscle weakness, pain or tingling in arms or legs, and possible swelling of feet or lower legs. In addition, if severe, lack of thiamine may cause mental depression, memory problems, weakness, shortness of breath, and fast heartbeat. Your health care professional may treat this by prescribing thiamine for you.

Thiamine may also be used for other conditions as determined by your health care professional.

Claims that thiamine is effective for treatment of skin problems, chronic diarrhea, tiredness, mental problems, multiple sclerosis, nerve problems, and ulcerative colitis (a disease of the intestines), or as an insect repellant or to stimulate appetite have not been proven.

Injectable thiamine is administered only by or under the supervision of your health care professional. Other forms of thiamine are available without a prescription.

Thiamine is available in the following dosage forms:

    Oral
  • Elixir (Canada)
  • Tablets (U.S. and Canada)
    Parenteral
  • Injection (U.S. and Canada)


Importance of Diet

For good health, it is important that you eat a balanced and varied diet. Follow carefully any diet program your health care professional may recommend. For your specific dietary vitamin and/or mineral needs, ask your health care professional for a list of appropriate foods. If you think that you are not getting enough vitamins and/or minerals in your diet, you may choose to take a dietary supplement.Thiamine is found in various foods, including cereals (whole-grain and enriched), peas, beans, nuts, and meats (especially pork and beef). Some thiamine in foods is lost with cooking.

Vitamins alone will not take the place of a good diet and will not provide energy. Your body also needs other substances found in food such as protein, minerals, carbohydrates, and fat. Vitamins themselves often cannot work without the presence of other foods.

The daily amount of thiamine needed is defined in several different ways.

    For U.S.-
  • Recommended Dietary Allowances (RDAs) are the amount of vitamins and minerals needed to provide for adequate nutrition in most healthy persons. RDAs for a given nutrient may vary depending on a person's age, sex, and physical condition (e.g., pregnancy).
  • Daily Values (DVs) are used on food and dietary supplement labels to indicate the percent of the recommended daily amount of each nutrient that a serving provides. DV replaces the previous designation of United States Recommended Daily Allowances (USRDAs).
    For Canada-
  • Recommended Nutrient Intakes (RNIs) are used to determine the amounts of vitamins, minerals, and protein needed to provide adequate nutrition and lessen the risk of chronic disease.

Normal daily recommended intakes in milligrams (mg) for thiamine are generally defined as follows:

Persons U.S.

(mg)
Canada (mg)
Infants and children

Before Using This Medicine

If you are taking this dietary supplement without a prescription, carefully read and follow any precautions on the label. For thiamine, the following should be considered:

Allergies- Tell your health care professional if you have ever had any unusual or allergic reaction to thiamine. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.

Pregnancy- It is especially important that you are receiving enough vitamins when you become pregnant and that you continue to receive the right amount of vitamins throughout your pregnancy. The healthy growth and development of the fetus depend on a steady supply of nutrients from the mother. However, taking large amounts of a dietary supplement in pregnancy may be harmful to the mother and/or fetus and should be avoided.

Breast-feeding- It is especially important that you receive the right amounts of vitamins so that your baby will also get the vitamins needed to grow properly. However, taking large amounts of a dietary supplement while breast-feeding may be harmful to the mother and/or baby and should be avoided.

Children- Problems in children have not been reported with intake of normal daily recommended amounts.

Older adults- Problems in older adults have not been reported with intake of normal daily recommended amounts. Studies have shown that older adults may have lower blood levels of thiamine than younger adults. Your health care professional may recommend that you take a vitamin supplement that contains thiamine.

Other medicines- Medicines or other dietary supplements

Although certain medicines or dietary supplements should not be used together at all, in other cases they may be used together even if an interaction might occur. In these cases, your health care professional may want to change the dose, or other precautions may be necessary. Tell your health care professional if you are taking any other dietary supplement or prescription or nonprescription (over-the-counter [OTC]) medicine.
