I am severely allergic to sulfa and took Lasix (one tablet) and went into severe shock. I had to be on a respiratory and go through dialysis. If you have a severe allergy do not take Lasix.

According to my PDR the same drug book the doctors use it doesn't actually have Sulfa in it but can cause a cross reaction if you are severely allergic to Sulfa Drugs. Which means if you are severely allergic to the point where you go into anaphylatic reaction than you may have a problem with Furosemide (Lasix). If you are allergic to Sulfa drugs than don't take the Furosemide for your own safety is the best bet a reaction can occur as the Furosemide builds up. Good luck, marjorie zych
