I'm taking 50mg ammitrypline at night and 75mg venafaxaline in morning for chronic lower back pain .is it ok to take vitamin b as i read this helps.

Likely: These vitamins should be O.K., but the best authority is your pharmacist. Just ask him if these all go together. The medications you mentioned are interesting. Perhaps you need to see an osteopath, or what in england is called a practitioner of "orthopedic medicine", for another opinion about your problem. Some people with these symptoms are helped by natural therapies.

Try it.: You can certainly try it. There is no significant down side to the medication and no significant drug interaction.

Yes : Lower back pain treatment with vitamin b has not been scrutinized to same degrees as later medical interventions have; therefore, it's not possible to base conclusive opinions on evidence-based medicine. However, congratulation anecdotal experience of physicians indicates a potential benefit. Be it a placebo or organic effect, the potential benefit gained far out do any potential harm.
