Lantus and Nyquil drug interactions - a phase IV clinical study of FDA data

Summary:

Drug interactions are reported among people who take Lantus (insulin glargine recombinant) and Nyquil (acetaminophen / dextromethorphan / doxylamine / pseudoephedrine). Common drug interactions include weight decreased among females and nasal disorder among males.

The phase IV clinical study analyzes what interactions people have when they take Lantus and Nyquil. It is created by eHealthMe based on reports of 16 people who take the same drugs from the FDA, and is updated regularly.
