When it comes to painkillers or other medications everyone is different. Patient A may be fine with one drug, where patient B has a problem. Patient A may have a problem with another drug, where patient B does not have a problem.
For those with tinnitus, it's often about how drugs will affect hearing.
According to Konrad Konradsson, a Swedish audiologist, painkillers with acetyl saticylic acid are not advised for those with tinnitus. Many other medical professionals across the net agree, but also maybe consideration should be given to next paragraph.
No one ready knows what medication may be OK or not for a certain person. All one can do is play the odds. Researching the class of drugs for a particular use should be done. Consider tinnitus against age, gender, usage term, and amount of dose. Generics are usually listed as safer, but that's a blanket medication statement.
After research, a personnel list of conditions considered against the above paragraph, a list of drugs that could be more acceptable or fine from experience should be kept in wallet or purse. I often use Drug.com as one source of assistance.
