Treating a NitroMist Overdose
Treatment for a NitroMist overdose, if necessary, will involve supportive care, which consists of treating the symptoms that occur as a result of the overdose. Of greatest importance, usually, is an effort to increase blood pressure. To do this, intravenous fluids can be quite useful, but can also be dangerous in certain individuals with kidney failure or congestive heart failure.If methemoglobinemia occurs, the treatment of choice is usually methylene blue, given intravenously (by IV). Methemoglobinemia is a condition in which the oxygen carried in the bloodstream cannot be released to the body's tissue normally. It can be serious if left untreated.
It is important that you seek medical attention immediately if you believe that you or someone else may have used too much NitroMist.
