Nicotinamide and Lidoderm drug interactions - a phase IV clinical study of FDA data
Summary:
Drug interactions are reported among people who take Nicotinamide (niacin and niacinamide (vitamin b3)) and Lidoderm (lidocaine). Common drug interactions include contusion among females.
The phase IV clinical study analyzes what interactions people have when they take Nicotinamide and Lidoderm. It is created by eHealthMe based on reports of 14 people who take the same drugs from the FDA, and is updated regularly.
