Glutathione injections are used to halt the expanse of diseases that destroy neurons. Parkinson's Disease, as well as others, are damaged by the prevention of the oxidation process caused by the drug. A variety of symptoms and side effects can arise from the use of the medicine, however. Some of these are simply minor, while others can cause long-term health concerns. It's important to always follow the procedures set out by a professional physician.
As an antioxidant, glutathione can impact the level of the molecules that already exist in the bloodstream. According to the Textbook of Cosmetic Dermatology, too many antioxidants that naturally occur in the body means that a glutathione injection will have little or no effect.
According to the Journal of Nutrition, people can develop serious digestive problems from the use of glutathione. Severe pains in the abdomen, excess gas and diarrhoea are all commonplace, most notably in people who suffer from liver and kidney problems.
Glutathione also possesses toxic properties that can effect a person's nervous system. According to the Aging Studies Institute, large does of glutathione can adversely effect a person by causing shakes and nervous twitches as well as forms of anxiety and depression.
Selenium can have a negative effect on a person receiving glutathione injections. These side effects appear when a person is exposed to 400 milligrams of selenium while on a glutathione regimen. According to the Agency for Toxic Substances and Disease Registry, this effect will cause numbness in the limbs, whitening of the nails and possibly hair loss.
A built-up tolerance of the drug can also have negative impacts on a person's health. Over the course of time, usually around six months, a person needs more and more glutathione injections for the same effect. This increases the likelihood of adverse symptoms according to the Journal of Nutrition.
