Is niacinamide a medication that nourishes the heart?

Niacinamide is generally not a medication used for nourishing the heart.

Niacinamide belongs to the vitamin class of drugs, also known as vitamin B3 or vitamin PP. Since vitamins are essential nutrients for the human body, niacinamide serves as a nutritional component and can be used to treat diseases caused by niacinamide deficiency, such as pellagra, stomatitis, glossitis, coronary heart disease, viral myocarditis, and rheumatic heart disease. Although niacinamide has vasodilatory effects and improves blood supply to the heart, it is not classified as a cardiac-nourishing drug.

Pregnant women in the early stages of pregnancy should use niacinamide with caution, and individuals allergic to this medication must avoid it. Niacinamide may have an antagonistic interaction with isoniazid; therefore, when taking isoniazid long-term, appropriate supplementation of niacinamide may be necessary. Acute allergic reactions such as urticaria, lip swelling, and laryngeal edema may occur after taking niacinamide. Thus, the medication should only be taken under medical supervision, and self-medication must be avoided.

During treatment, maintain a light diet and avoid spicy, raw, cold, greasy, or other irritating foods. If any adverse reactions occur, discontinue the medication immediately.
