i am answering based off of research i just did on drug interactions because of my own after effects. nyquil inhibits the liver enzyme that breaks down dextromethorphan. which means that this cough suppressant stays in your system for a long period of time. personally i am finding it unpleasant and consider myself illegal to drive. if nyquil as no effect on your sleepiness or balance you may be ok. i am basically dizzy for a prolonged period.
i take bupropion and i want to take nyquil for my cold. is that safe?
