Treatment of Vitamin B3 Deficiency in Chronic Alcohol Abuse

Vitamin B3 (niacin) deficiency — a recognised cause of pellagra — occurs with particular frequency in the setting of chronic alcohol abuse. Patients in this population are prone to multivitamin deficiencies, which shapes both the presentation and the management approach.

Clinical context — chronic alcohol abuse

Chronic alcohol abuse is a direct causal driver of pellagra. Because multivitamin depletion is common in this group, management cannot focus on B3 repletion alone. Causal treatment — including appropriate specialist consultations and, ultimately, addiction therapy — is an essential part of care alongside vitamin replacement.

Treatment approach (partial overview)

Management centres on nicotinamide, used together with preparations of other B-complex vitamins. Causal treatment, incorporating specialist referral and addiction therapy, forms a required component of the overall regimen. The complete protocol — including the full treatment sequence and specifics — is available via the link below.

For pellagra developing due to alcohol abuse or eating disorders (e.g., anorexia nervosa), appropriate causal treatment includes proper specialist consultations, and, ultimately, addiction therapy or psychotherapy, respectively.
It is vital to administer preparations of other group B vitamins as well, because patients with pellagra often suffer from multivitamin deficiencies.
This is particularly true for chronic alcohol abusers.
