Can you take meclizine and Vicodin together?

Not a very good idea! They are both prescribed for pain, so take one or the other. Mixing those two will make you feel awful.

No. Mixing the two can cause you to stop breathing. If you pass out while taking these two medications together, you risk vomiting, and then breathing in your vomit, and thus drowning in it. This happened the other day in the Emergency Room where I work at. Don't ever mix opiate medications, such as morphine and Vicodin. It's a really great way to die.
