Thiamine is a vitamin used by the body to break down sugars in the diet. The medication helps correct nerve and heart problems that occur when a person's diet does not contain enough thiamine.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
Thiamine comes in tablets to take by mouth. It is usually taken three times a day with meals. If you have a thiamine deficiency, your doctor may prescribe thiamine for 1 month or more. Follow the directions on your prescription label or package label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take thiamine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Thiamine should be taken with meals. If you are taking an extended-release (long-acting) product, do not chew or crush the tablet. There are some tablets that can be crushed and mixed with food.
Before taking thiamine,
Your doctor may suggest that you eat more potatoes, whole-grain cereals and breads, meats (especially pork and liver), peas, beans, and nuts to increase the thiamine in your diet.
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( Web Site) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. Web Site

Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your response to thiamine.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
