I am taking Diclofenac (75mg) each day for Arthritis inflammation. My blood pressure has recently been running quite low and at the same time, my heart rate has been elevating above 100+ This happens upon standing or working (really not exerting , just normal household duties) for any length of time. I am also experiencing rapid heart beat , shortness of breath and tiredness and have to stop and rest for a period of time. I have been taking Diclofenac for several months every day. Are these symtoms common with taking this particular prescription? Is it dangerous for me to continue taking Diclofenac each day? I thank you for any information.
Hithank you for asking your concern on Chat Doctor. Answering to your first question it is very much unlikely to develop these symptoms due to diclofenac. Most common side effect of diclofenac or diclofenac like Chat Doctor.  Gastritis can present with rapid heart beat, shortness of breath in few instances. Antacids should be taken along with diclofenac to decrease gastric damage. But I would like to suggest consulting your physician for these symptoms to check for hypertension, diabetes. I would suggest doing an electrocardiogram (ECG), urine for microprotein or protein. I will be important to check kidney status because you are having a long history of taking diclofenac. Answering to your second question is yes long term diclofenac is dangerous not only for you but to anybody. Gastric ulcer and kidney failure are the most devastating complication it gives. Feel free to ask any doubts thank you regards
