After taking a break from HRT I went back on in September. The specialist prescribed Indivina 1mg/5mg which I took for about 3 weeks before I started to see results but I was very pleased. The hot sweats and freezing cold episodes had subsided to warm and cool periods which were a great improvement. I had my second prescription, dose 2mg/5mg, from a different chemist and they gave me Duova. The drug is supposedly the same, from the same manufacturer, the instructions on the box and the tablet strip are in French but the info document is English. After about a month I started to wake up again with night sweats. And I'm much warmer and colder during the day. Could this be that the tablets are different?
