I started taking metermine 30mg for a month and then my dr up my dose to 40mg. I have been on these for 1 1/2 months and have been breaking out in rash on my forehead. I thought I may have been allergic to hairspray or shampoo etc. but I hadn't changed my brands. Is this from the medicine? What can I put on it to help? Never had spots on my face before. I am loosing weight and want to continue. I do get dry mouth and sometime nausea. Drinking lots of water and apple sorts nausea.
