Hi there new to the site and looking for advice. Basically I've had asthma for 33 yrs since a young child and had my best control between the ages of 26 and 36, only using salbutumol when required and no preventer on the whole. All that changed when I became ill with then got diagnosed with chronic fatigue syndrome 20 mths ago, following a bad chest infection. Anyway to cut a long story short, the beclomethasane that I was on was no longer doing its job so was put on seretide 13 days ago. A few days ago I stated noticing my heart racing after taking it. It got worse the more I continued so gp advised coming off it. Her plan is to give my prednisolone for 20 days in reducing doses every 5 days, in currently on 40mg (day 3). My problem is continued palpitations /raised heart rate which I thought would have resolved by now! This morning I woke up and resting heart rate was 100bpm, I'm usually around 60 ish. It seems worse as the day goes on and when I'm trying to relax I notice it more. Pharmacist tried to fob me off saying I am probably anxious about taking the prednisolone and that may be causing it! (I've only ever had to take it once before). Has anyone any thoughts or advice?? Could the sameterol still be causing the tachycardia? I was on seretide 125. Thanks.
