Newly diagnosed with Type 2, I was prescribed Metformin (500gm), one tablet a day for a week, and then two after that. Within a few days I started to get very bad hives, particularly at night, and swollen lips in the morning, so I stopped taking it. However I was told it was all in the mind and to have another go. The results were the same. I've now been put on a low dosage Gliclizide tablet (one a day) but am still getting very bad hives, particularly in the early hours of the morning. Has anyone else experienced this and what have they taken to alleviate the symptoms? I am not overweight, eat healthily and do a lot of walking.
