The BMJ (what used to be called the British Medical Journal) just published an article stating that acetaminophen (ie Tylenol) has been found to provide no relief in low back pain (compared to a placebo). Acetaminophen was also related to a risk of having an abnormal liver test. The article included data from 13 randomized controlled trials (RCTs).
An RCT to evaluate a drug is a research study where one group of people receives the actual drug (in this case, acetaminophen) and the other group receives a placebo (a pill with no active ingredient, generally a sugar pill). Then, data is collected from both groups to see if either achieved any pain relief. In this analysis, it shows that whether you receive acetaminophen or a sugar pill, you had the same amount of pain relief – meaning that active drug had no real pain relief effect.
Although most of the patients I see find no relief from acetaminophen, a small percentage of patients do, so don’t completely dismiss this drug when it comes to helping your pain. However, if you do take acetaminophen, make sure that you’re not taking too much. The FDA recommends taking less than 3000mg a day. This means if you’re taking Extra Strength Tylenol (500mg), you can only take 6 pills a day, or regular strength, 300mg, 10 pills a day. Higher amounts can lead to liver damage that could even be life-threatening.
