I'd been taking a low dose of Temazepam for sleep problems for several years - would wake at 3 am and couldn't get back to sleep, which is not good when you have a responsible job.
Last week when I requested some more from my GP, he had changed them to Zopiclone - without any word to me of this. It set me off reading the instruction leaflets for both of them. Guess what I found on the Temazepam listed as a side effect: 'A very fast, uneven or forceful heartbeat (palpitation)'. Just what I suffer with - words fail me!! Both lots of tablets will go straight back to the chemist who dispensed them.
Just a warning to everyone to make sure that the tablets you are taking don't have that side effect. Why did my doctor change me to Zopiclone? At first I thought it must have been brought to his attention of the effect on the heart, but a nursing friend has told me it's because they are cheaper.
