I AM A HEART PATIENT With Four Stents. I Am

I AM A HEART PATIENT with four stents. I am on aspirin, Glipizide-Metformin 5MG/500MG TABS twice a day, Ramipril 2.5MG capsules, Carvedilol 3.125MG tablets twice a day, Furosemide 20MG tablets. Will this cause problems with taking Doxycycline Monohydrate 100MG capsules twice a day, prescribed for me by my dermatologist for an intensely itching rash? Nothing he has prescribed so far has been effective. I have had this rash for a year. I started Doxycycline on May 5th and I have a sore spot in my stomach that started today.
