PYRIDOXINE (VITAMIN B6) + NOT AVAILABLE + DOXYLAMINE
Pyridoxine (vitamin B6): Pyridoxine, also known as vitamin B6, is a water-soluble vitamin that is essential for many bodily functions. It is naturally found in foods such as fish, poultry, meat, grains, and vegetables.
Use:
Pyridoxine is primarily used as a dietary supplement to treat or prevent vitamin B6 deficiency. It is also used to help alleviate certain conditions that may benefit from increased levels of this vitamin, such as nervous system disorders, anemia, and certain types of seizures in infants.
Mechanism of action:
Pyridoxine plays a crucial role in the synthesis, breakdown, and conversion of various compounds in the body. It is involved in the metabolism of proteins, carbohydrates, and fats, allowing these nutrients to be utilized for energy. Additionally, vitamin B6 is required for the synthesis of neurotransmitters such as serotonin, dopamine, and gamma-aminobutyric acid (GABA), which play important roles in mood regulation and nervous system functioning.
Dose:
The recommended daily dose of pyridoxine varies based on age, sex, and specific health conditions. For adults, the recommended daily intake ranges from 1.3 to 2.0 mg. Higher doses may be required for individuals with certain deficiencies or medical conditions, as determined by a healthcare professional. It is available in oral tablet, capsule, or liquid formulations.
Side effects:
Pyridoxine is generally considered safe when taken at the recommended doses. However, excessive long-term supplementation can lead to adverse effects, including numbness, tingling, or pain in the hands or feet (known as peripheral neuropathy). High doses of pyridoxine have also been associated with skin rashes, photosensitivity, and gastrointestinal upset such as nausea, vomiting, and abdominal pain.
It is important to consult with a healthcare professional before starting any supplementation, as they can provide individualized dosage recommendations and monitor for any potential interactions or adverse effects.

Doxylamine: Doxylamine is an antihistamine drug that is commonly used to relieve symptoms of the common cold, allergies, and sleeplessness. It is available both over-the-counter and by prescription.
The mechanism of action of doxylamine involves its ability to block the effects of histamine, a substance that the body releases in response to allergens. By binding to histamine receptors, doxylamine prevents the physiological effects of histamine, such as nasal congestion, itching, and a runny nose. Additionally, doxylamine has sedative properties that can induce drowsiness, making it effective for promoting sleep.
The recommended dose of doxylamine varies depending on the formulation and indication. For adults using the drug to relieve symptoms of the common cold or allergies, the typical dose is 12.5 to 25 mg taken every 4 to 6 hours, with a maximum daily dose of 75 mg. When used as a sleep aid, individuals are typically advised to take 25 mg of doxylamine 30 minutes before bedtime. It is important to follow the instructions provided by the healthcare professional or the package insert regarding dosing.
Common side effects of doxylamine include drowsiness, dry mouth, blurred vision, constipation, and urinary retention. These side effects are generally mild and temporary. However, some individuals may experience more severe adverse effects, such as dizziness, confusion, difficulty concentrating, or an irregular heartbeat. If these symptoms occur, it is recommended to seek medical attention immediately.
It is worth noting that doxylamine may interact with other medications, including sedatives, tranquilizers, and certain antidepressants. Therefore, it is important to inform your healthcare provider about all the medications you are currently taking to avoid potential drug interactions.
Furthermore, doxylamine is not recommended for use in children under the age of 12, and caution should be exercised in older adults, as they may be more prone to experiencing adverse effects.
Overall, doxylamine is an antihistamine that is commonly used to relieve symptoms of allergies, the common cold, and insomnia. It works by blocking the effects of histamine and inducing drowsiness. Like any medication, it has potential side effects that should be considered before use, and it is important to follow the recommended dose and instructions provided by a healthcare professional.
