Iv Glutathione Drip

Got Iv glutathione drip done by doctor. While this was professionally done, I was plagued with anxiety. Anxious of possible side effects. Especially Steven Johnson's Syndrome. My skin did lightened from medium brown to light brown but I had skin pain on my leg thigh and pain when sit down which could be due to vit d deficiency. I had a blood test and was prescribed vit d. Not sure if Iv skin lightening is safe. Doctor was preaching to me how safe the procedure was but never really discussed future side effects. I will use the glutathione suppositories and leave the Iv glutathione drip alone.
