Hi Doctors, I'm a 59 years ago female .I just found out I have an Ulcer.Well I've been under a lot of stress.My Mother's Death Certificate was just signed after over 7 grueling months. My mother passing away in the hospital under questionable circumstances 2 days after having a tracheostomy. I'm Sorry,Back to my original question . My Gastroenterologist dr prescribed Famotidine for my Ulcer is this okay to take with medicine I take for lower back pain Lyrica 100 mg 2x aday, hydrocodone 10-325 tabs 2 or 3 times aday,and OxyContin 20 mg 2 or 3 times aday And is there any adverse effects combining all these medicines.. I have noticed headaches. Thank you
