any patient-specific treatment instructions should be done by the medical provider who is caring for you but if you do not need the pain relief from vicodin now you can switch to ibuprofen at any time if your doctor is okay with it. the vicodin will not be bio-effective after six hours or so so anytime after that.
can i switch from vicodin to advil without waiting for the vicodin to clear my system? . i have shingles (yes i had the shot too) have been taking acyclovir and vicodin. the vic didn't kill the pain so i been adding 2 advil. after 5 days my feet started swelling and i was worried about my kidneys. i read that acy shouldn't be taken with advil so i stopped the adivil 2 days ago. swelling didn't decrease i stopped the acy about 28 hrs. ago still no change in the swelling. i've decided to stop the vic 5-500 and stick with 600 mg. advil.
