Is it ok to take nyquil, a decongestant and naproxen together?

Probably: Different forms of nyquil have different ingredients. If it contains Acetaminophen for pain or fever, you may not need to also take naproxen.

Possibly: Check label for type of nyquil u r using: if it has acetaminophen, u don't need the naproxen. The other two meds should be ok together; decongestant may offset the sedative effect of nyquil. Always read labels carefully for ingredients.
