Drug and food/lifestyle interactions
niacin food/lifestyle
Applies to: Niaspan (niacin)
GENERALLY AVOID: Ethanol can exacerbate the cutaneous flushing that is a common side effect of niacin. At least one case of delirium and lactic acidosis has been reported with coadministration of these drugs, although data are limited.
MANAGEMENT: Coadministration should probably be discouraged, particularly since chronic consumption of large amounts of alcohol is associated with hyperlipidemia.

Applies to: Niaspan (niacin)
A single case has been reported in which cutaneous flushing and tremors were noted in a woman who was taking niacin while wearing a nicotine patch. The mechanism is suspected to be synergistic cutaneous vasodilatory effects. The clinical significance of this possible interaction is not known.
