I have recently been put onto patches but am finding the effects only last for 2 days not 3 to 4 before they run out and I get all the effects like hot flushes, headaches etc. Is it just that it will take time for my system to adjust or I wondered maybe if I just absorb fast. I was changed onto patches as my blood levels were so low (53) and the Consultant felt I would benefit from a low steady absorption rate which she says patches are better for. Does anyone else find their patch runs out long before it is meant to? Many thanks.
