Does vicodin raise my blood pressure?

No, it can rather lower blood pressure. Pain and discomfort can definitely raise blood pressure otherwise.

If anything, Vicodin has the side effect of decreasing blood pressure, not increasing. Dizziness would be something to watch for as something that might be an indication of a drop in blood pressure, although the drug can also cause dizziness without affecting blood pressure as well. Either way, if a person has difficulty tolerating the medication, she should let her doctor know.
