Lactobacillus Acidophilus Overview

Lactobacillus Acidophilus Lactobacillus acidophilus is a type of lactic acid-producing bacteria that is commonly found in the human gut, as well as in other areas of the body such as the mouth and vagina. L. acidophilus can also be found in fermented foods such as yogurt and kefir. It is commonly utilized in probiotic dietary supplements as it is considered a "friendly" or "beneficial" bacteria because it helps to maintain the balance of microorganisms in the body, and is purported to help improve digestion and boost the immune system. Some studies have suggested that L. acidophilus may also have a role in preventing and treating certain conditions such as diarrhea, vaginal yeast infections, and eczema.

Peginterferon alfa-2b Overview

  • Peginterferon alfa-2b is used alone or in combination with ribavirin (a medication) to treat chronic (long-term) hepatitis C infection (swelling of the liver caused by a virus) in people who show signs of liver damage and who have not been treated with interferon alpha (medication similar to peginterferon alfa-2b) in the past. Peginterferon alfa-2b is in a class of medications called interferons. Peginterferon alpha-2b is a combination of interferon and polyethylene glycol, which helps the interferon stay active in your body for a longer period of time. Peginterferon alpha-2b works by decreasing the amount of hepatitis C virus (HCV) in the body. Peginterferon alfa-2b may not cure hepatitis C or prevent you from developing complications of hepatitis C such as cirrhosis (scarring) of the liver, liver failure, or liver cancer. Peginterferon alfa-2b may not prevent the spread of hepatitis C to other people.
