Pyridoxine is vitamin B6. Vitamins occur naturally in foods such as meat, poultry, nuts, whole grains, bananas, and avocados. Vitamin B6 is important for many processes in the body.

Pyridoxine is used to treat or prevent vitamin B6 deficiency. It is also used to treat a certain type of anemia (lack of red blood cells). Pyridoxine injection is also used to treat some types of seizure in babies.

Pyridoxine taken by mouth (oral) is available without a prescription. Injectable pyridoxine must be given by a healthcare professional.

Pyridoxine may also be used for purposes not listed in this medication guide.

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Pyridoxine tablets are taken by mouth. Injectable pyridoxine is injected into a muscle or into a vein through an IV. You may be shown how to use injections at home. Do not give yourself this medicine if you do not understand how to use the injection and properly dispose of needles, IV tubing, and other items used.

You may also consult the Office of Dietary Supplements of the National Institutes of Health, or the U.S. Department of Agriculture (USDA) Nutrient Database (formerly "Recommended Daily Allowances") listings for more information.

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 (http://goo.gl/c4Rm4p) 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. http://www.upandaway.org
