Just started a combination of estradot and prometrium... dizziness I think arising from only 3 -4 doses of the prometrium and/or combo of estradot and so stopped but kept patch on til end of 3 day cycle. Now severe break out in hives all over legs and arms. has anyone else had this reaction. trying to rule out other factors but have not had this sort of reaction to anything else prior and only new thing is medication. tnx based in Australia
