What Is Niacinamide?
Niacinamide (vitamin B3) is a prescription medication used to manage niacin deficiency and its associated symptoms, including skin changes, digestive disturbances, and neurological effects. It works by serving as a precursor to NAD and NADP, coenzymes essential for cellular energy metabolism and DNA repair. With the right dose and ongoing monitoring, most patients achieve stable vitamin B3 levels and significant symptom relief.

Is Online Niacinamide Treatment Right for You?
Doctronic can evaluate patients who may benefit from prescription niacinamide (vitamin B3) for niacin deficiency or related conditions such as pellagra, inflammatory skin conditions, or documented low niacin levels. Our licensed physicians review your health history and current symptoms to determine whether niacinamide is appropriate for you.
Because niacinamide affects skin integrity, gastrointestinal function, and neurological health, your physician will consider any relevant history of nutritional deficiencies, chronic digestive disorders, or skin conditions before prescribing. Patients with liver disease or taking certain medications may require additional monitoring.

Frequently asked questions
Niacinamide and niacin are both forms of vitamin B3, but niacinamide does not cause the flushing side effect commonly associated with niacin. Niacinamide is often preferred for treating deficiency and skin conditions because it is better tolerated by most patients.
Prescription niacinamide is primarily used to treat niacin deficiency and pellagra, a disease caused by severe niacin deficiency that causes the 4 Ds: dermatitis, diarrhea, dementia, and death if untreated. It is also used to support certain inflammatory skin conditions.
Symptoms of niacin deficiency include a rough, scaly skin rash that worsens in sunlight, digestive problems such as nausea and diarrhea, fatigue, depression, headache, and in severe cases, confusion or cognitive changes.
Dosage depends on the severity of deficiency and the condition being treated. For pellagra, doses typically range from 100 mg to 500 mg daily in divided doses, though your physician will determine the appropriate dose based on your individual evaluation.
Niacinamide is generally well tolerated at recommended doses. Possible side effects include nausea, stomach upset, and mild skin reactions. Unlike niacin, niacinamide does not typically cause flushing. High doses may affect liver enzymes, so monitoring may be recommended.
Patients with active liver disease, a history of peptic ulcer, or known hypersensitivity to niacin or niacinamide should discuss these conditions with their physician before starting treatment. Your doctor will review your full health history during the evaluation.
Doctronic uses AI-powered evaluation to gather your symptoms and health history, which is then reviewed by a licensed physician. If appropriate, the physician creates a personalized treatment plan that may include a prescription, all without an in-person visit.
