The most well known medicine for Candida might be Nystatin. According to the PDR, no detectable blood levels are found following oral administration of the drug at recommended doses. It is, therefore, effective at reducing localized vaginal or intestinal yeast growth, but cannot travel through the blood stream to handle the infections in other areas. Another drug Nizoral impairs the productions of ergosterol, a vitamin D like substance, which is vital to the integrity of the yeast cell membranes. This drug is difficult for Candidiasis patients to absorb because proper stomach acid is required to absorb it.
Most patients are deficient in stomach acid.
Yeast infections sometimes produce symptoms that make people believe they have excess acid. Recent evidence shows this drug may cause serious liver damage or even fatal reactions. The PDR states that these drugs can only be taken for a short period of time due to toxicity. I do not believe they can be taken long enough to kill the Candida. In the natural health field many substances have bean promoted as being able to reduce yeast Infection.
