The last two times I have been in the hospital for severe asthma problems I was given IV Magnesium Sulfate in addition to the IV steroids and nebulizer treatments. Has anyone else been given IV Magnesium Sulfate in the hospital? If so, was it helpful for you? Did your doctor recommend you take a Magnesium supplement after you were discharged? So far, my doctor has not recommended that I take a daily supplement.
