Has anybody been prescribed phyllocontin continus 225 mg prolonged release tablets Aminophylline Hydrate? I was given these tablets at the end of August this year and was told they would help keep my lungs open. I was told to take 2 in the am. and 2 in the pm I was only taking one in the am. and 1 in the pm. my heart rate rose to 126 bpm to 132 bpm which in turn made me so breathless. I was so distressed and scared, I did not need this on top of c.o.p.d. I rang my Dr who told me I had anxiety problems, all he wants to do is put me on antidepressants. I told him I did not need these at all. I have stopped taking the phyllocontin now. I have also been trying to do a p r course and could not understand why I was having so many problems. now I know that it as my heart rate that was holding me back. when I have asked for advice nobody seems to wont to know or help! Can anyone give mean advice? Best Wishes to all!
