I'm pre-diabetic, and I've been this way many years. So as a precaution my Dr gave me Metformin 500 mg. On the 3rd day I had an allergic reaction. I was itchy all over, and I felt slightly short of breath for several hours. I've stopped taking it and those symptoms are gone. One relative said she never heard of anyone being allergic to Metformin, and the pharmacist is also skeptical. The Dr is out of town until next week. Has anyone ever heard of anyone being allergic to Metformin? I'm also highly allergic to any form of Sulfer.
Yes! - Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
Yes I am allergic to metformin. It gives me hives.
I know this post is two years old. But wanted to let you know that I too have the exact problem. I am allergic to Sulfa and Metformin as well as Glipizide.
My provider says she has never heard of these allergies. But I have found others on the web whom have stated they have. It's very frustrating...
I have recently discovered an allergy to sulfa. This lead me to think about metformin. I have come off metformin and my neutrophils in my blood have come down so I am no longer showing with a high c reactive protein either. So metformin lead to palindrome arthritis (allergy)and high white blood cells. (Showing infection in body). I am now back to normal!
I was put in the hospital for a week because of Metformin, I called and told the hospital what symptoms I was having , they said it is not likely to be Metformin, so I continued to take the medicine. 3 days after being on the medicine I was put in ICU,was place on a ventilator. heart machine, medicine to contact the medicine to get it out of my system . I literally thought I was going to die. They told my family that if I would have continued to take this drug I would have died. So if any one says you can not be allergic to this drug they are lying.
I was on Metformin for 20 years with no issues. Then, I did keto, lost weight and was able to get off all meds. I was SO healthy! Then I developed Meniere's disease and Ramsay Hunt Syndrome. RHS comes with Bells Palsey, Shingles in my ear and throat and severe dizziness and nausea. Not fun to say the least. I live in a rural area and it took some time to be diagnosed. By then, my blood sugar was back up so I restarted metformin again. My dizziness, vomiting and diarrhea increased greatly, but I attributed it to RHS. I was weak and bedridden for weeks. I was constantly itchy and my breathing became difficult. I usually took my meds at night, and vomited all night long till I had nothing left to vomit and still continued to dry heave. One weekend, we were leaving for a 2 day trip, and I took my meds in the morning instead for convenience.
20 minutes later, down the road, I began vomiting. My poor bf kept pulling over. I knew right then that it was the metformin. I have never taken it again, and I feel great. All of my other symptoms are managed for the most part. I'm on insulin now, but working towards getting healthy enough to get off of it. BTW, I dreaded the insulin and fought it as long as I could. But it really isn't that bad, and I feel MUCH better!
I guess so much has changed in my body, it couldn't tolerate metformin anymore. Good riddance! Lol
