There is no drug interaction between NyQuil and Protonix (Pantoprazole). They are considered safe to take together.

Having said that, for optimal effects, most guidelines recommend that proton pump inhibitors like Protonix should be taken on an empty stomach, 30 to 60 minutes before food or other medication.

Protonix is generally taken in the morning and therefore co-administration with a night-time cough/cold medication like NyQuil doesn't occur often.

Nevertheless, if you take Protonix in the evening, you can take it with NyQuil as there is no interaction, but ideally, take Protonix at least 30 minutes prior to NyQuil.

Section Summary
There is no drug interaction between NyQuil and Protonix. However, Protonix works best if taken on an empty stomach, before food or other medication.

About Protonix

Protonix (Pantoprazole) is a proton pump inhibitor (PPI) that is dosed once every 24 hours (although is dosed twice daily for certain indications).

It is used for a variety of indications including gastroesophageal reflux disease (GERD), gastric and duodenal ulcers as well as Helicobacter pylori (H. pylori) infections. 

Protonix is currently available by via prescription only, either as a tablet, granules for suspension or as a IV solution.

In terms of dosing, all PPI medications should be dosed about 30 to 60 minutes before food for optimal effects.

Lastly, Protonix does not significantly inhibit liver metabolizing enzymes and compared to other currently available PPIs, like Prilosec, it has the lowest potential for drug interactions.
