I have asthma and also high blood pressure which is treated successfully... I have started to take low dose aspirin at night to to look after my heart, I had SVT which was treated eventually with an ablation, I understood aspirin to be a useful protector, but I am coughing with a dry cough really badly at night and this is making me very tired...should I give up on the idea of using aspirin as a protector? I am a 68 year old woman
