I have now been taking Sildenafil (20mg x3 per day) and now am finding my resting pulse rate seems to be 96 beats most of the time when it was normally 70 before the medication, This is the opposite to what I expected. Can anyone advise please?
Have you discussed this with your doctor? There are other medications that can be prescribed for PAH and it's possible you might do better on one of these.
To me it sounds like an adverse reaction or side effect I would tell my doctor because it certainly can't be very comfortable and I don't think it would be very good for you it is also side effect from other blood pressure meds
