this is a good question that you can always ask your pharmacist. you can be on both of these medications at the same time. i would recommend staying home if possible when you take your relpax with the norco so you can see how they make you feel (it may be hard to distinguish between the possible side effects and a migraine). make sure that you carry a personal medication list that has all of your medications including over-the-counter medications and make sure you show that list to your pharmacist doctor and other health care providers.
can i take relpax 40 mg for migraine when i take my norco for back pain? is there a side effect if i do mix these two?
