Pyridoxine
Pyridoxine, also known as vitamin B6, is a water-soluble vitamin essential for several important bodily functions, including amino acid metabolism, neurotransmitter synthesis, and hemoglobin production. It plays a critical role in maintaining the health of the nervous system and skin, and it is involved in the body's use of glycogen.Pyridoxine is indicated for the prevention and treatment of vitamin B6 deficiency, which may arise from various causes such as malnutrition, alcoholism, or certain medical conditions. It is also used to manage nausea and vomiting in pregnancy (morning sickness) and to alleviate symptoms of premenstrual syndrome (PMS). Additionally, it may be prescribed to manage certain genetic disorders and neurological conditions.
The dosage of pyridoxine varies depending on the individual's age, condition being treated, and other factors. For adults, the recommended daily allowance (RDA) is between 1.3 mg and 2 mg. However, doses used for medical treatment can be higher. For example, in cases of deficiency, a higher dose such as 10-50 mg daily may be prescribed. Always follow a healthcare provider's recommendations for the appropriate dosage.
Pyridoxine is generally safe for most people, but it may be contraindicated in individuals with known hypersensitivity to the vitamin. Caution is advised in individuals with certain medical conditions or those who are taking other medications that could interact with pyridoxine.
Patients with certain conditions, such as those with a history of heart disease or liver disease, should use pyridoxine with caution and under medical supervision. High doses of pyridoxine can lead to neurological symptoms such as peripheral neuropathy, so it is important to adhere to recommended doses. Pregnant and breastfeeding women should consult a healthcare provider before taking pyridoxine supplements.
Common side effects of pyridoxine are rare when taken in recommended doses. However, high doses can lead to side effects such as: Numbness or tingling in the extremities Sensory changes Loss of coordination Skin lesions Photosensitivity

Oral contraceptives: Certain birth control pills may decrease pyridoxine levels in the body. Other medications: Consult with a healthcare provider for a comprehensive list of possible
