Cod Liver Oil Overview

Cod Liver Oil Cod liver oil is derived from the liver of the Atlantic cod fish. It is a rich source of omega-3 fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), as well as vitamins A and D. Cod liver oil is used as a dietary supplement to provide the health benefits of omega-3 fatty acids and vitamins A and D. Omega-3 fatty acids are important for maintaining heart health and can help to reduce inflammation, lower blood pressure and triglyceride levels, and may decrease the risk of heart disease. While Cod liver oil and fish oil are both sources of EPA and DHA, there are some key differences between the two. For example, cod liver oil is derived from the liver of the Atlantic cod fish, while fish oil is typically derived from the body tissue of oily fish such as salmon, sardines, and anchovies. Additionally, cod liver oil generally has a stronger fishy taste and smell than fish oil due to its liver source.

Rifaximin Overview

  • Rifaximin 200-mg tablets are used to treat traveler's diarrhea caused by certain bacteria in adults and children at least 12 years of age. Rifaximin 550-mg tablets are used to prevent episodes of hepatic encephalopathy (changes in thinking, behavior, and personality caused by a build-up of toxins in the brain in people who have liver disease) in adults who have liver disease and to treat irritable bowel syndrome (with diarrhea) in adults. Rifaximin is in a class of medications called antibiotics. Rifaximin treats traveler's diarrhea and irritable bowel syndrome by stopping the growth of the bacteria that cause diarrhea. Rifaximin treats hepatic encephalopathy by stopping the growth of bacteria that produce toxins and that may worsen liver disease. Rifaximin will not work to treat traveler's diarrhea that is bloody or occurs with fever.

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