I was on Vicodin 10/325mg- 1 to 2 tabs every 4 hrs, as well as anti-depressants, and muscle relaxers. Then went to a new Dr. and was after several months put on Gabapentin 300mg 4xs a day as well as anti-inflammatories. Then increased to 600mg and one Vicodin instead of two after 3 years of being on 2. Pain increased and had side effects. Following month told to go from 600mg 4xs a day of Gabapentin to 1200mg 4xs a day and one vicodin every 4hrs as well as all other meds and suppose to start something called Duexis which has 800mg of ibuprofen (when it comes in the mail- its $1400.00 for a months supply at pharmacy). I figured 600mg to 1200mg of Gabapentin is too great a jump, so, trying 900mg for a week or so before increasing. Unfortunately 3 days in at 900 mg 4xs a day makes me very dizzy,nauseus,headache and unable to sleep. To be honest, not sure if Gabapentin helping.... had pain and inabilities still with high dose of Vicodin,but was functioning a lil . Now I still have pain but less functioning. Hoping things will get better as my head and body adjust to meds. I do not know if the Gabapentin is or will work. I was ok before, will always have a lot of pain and limited movement, but Vicodin is a narcotic now and taboo,so rather than let me function some, the government took away that and added side effects,extra meds, and less functioning by scaring doctors to take away one med and add 3 more with very high doses. Any suggestions other than surgeries as I have already tried- therapy,chiropractor,shock, shots, steroids, traction, ultra-sound, epidurals..... Going to stick with the Gabapentin for now and hope it works... staying at the 900mg 4xs a day till dizziness,etc... goes away. If it lasts more than a week this bad will call Dr. and not increase to 1200mg 4xs a day, I hope others are doing better or have a better combination... I had morphine in hospital and couldn't handle the dizziness, as well as Percocette, or any other pain meds. Anything stronger than vicodin is out as it makes me to dizzy to cope or walk, (Same as the Gabapentin the past 3 days). So hopefully someone has a better combo, please let me know?
