I have taken 1 tab 50 mg Tramadol every 12 hrs. 3 times now. It does not seem to be doing anything for my pain. I was taking 800 mg Ibuprofen every 4 hrs , just during daytime, and not more than 4 times in 24 hrs. I was feeling no pain but my doctor wanted me to try taking this Tramadol. She said I could take the Ibuprofen also so yesterday I tried taking half of the Ibuprofen I usually take but still had a very uncomfortable day. today I started taking the 800 mg. dosage again and the Tramadol 1 this morning . I also feel like my ability to think clearly is impaired , will not drive until this symptom goes away.
