###Human: What are the chances of getting internal bleeding with Excedrin and Citalopram? ###Assistant: Hello. I understand your concern and agree with you on the fact that both Citalopram and Excedrin increase the risk of bleeding. But the main problem is that taking Excedrin so frequently may lead to drug-induced daily headaches. From the other hand, Citalopram does not seem to be really effective in preventing headaches. For this reason, I would recommend discussing with your doctor on the possibility of switching to another medication for the prevention of headaches. In this regard, I would recommend switching to low dose Amitriptyline. I would like to know more about the description of your headaches in order to be able to suggest more treatment options.
