Same Overview

Same S-adenosyl-l-methionine (SAM-e or SAMe) is a compound that is found naturally in the body and is involved in various processes, including the synthesis of neurotransmitters and the metabolism of hormones. SAM-e has been studied as a potential treatment for a variety of health conditions, including depression, osteoarthritis, and liver disease. As a dietary supplement, it is most often used for improving symptoms of depression and for osteoarthritis. In regard to depression, research suggests that SAM-e may be more effective than placebo in reducing the severity of depression and may be as effective as certain antidepressants for some individuals. However, more research is needed. Similarly, for osteoarthritis, some studies show that it is as effective in reducing symptoms for some individuals as NSAIDs (e.g., ibuprofen). There are a variety of different forms of SAM-e supplements available on the market, typically different salt forms (e.g., sulfate, sulfate-p-toluenesulfonate, and butanedisulfonate), which may affect how well it is absorbed.

Rifapentine Overview

  • Rifapentine is used with other medications to treat active tuberculosis (TB; a serious infection that affects the lungs and sometimes other parts of the body) in adults and children 12 years of age and older. Rifapentine is also used with isoniazid (Laniazid) to treat adults and children 2 years of age and older with latent (resting or nongrowing) TB, including those in close contact with people who have active TB, a positive tuberculin skin test, human immunodeficiency virus (HIV), or those with pulmonary fibrosis (scarring of the lungs with an unknown cause). Rifapentine is in a class of medications called antimycobacterials. It works by killing the bacteria that cause infection.

  • Antibiotics such as rifapentine will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
