A doctor has prescribed me Voltaren 50mg and online research has indicated that some of my other prescriptions are not compatible. I take low dose aspirin 81mg daily. I also take Metformin ER 500mg 2x/day, Ranitidine 300mg once a day and Citalopram 40mg once a day, just to name a few. When I read many of the side effects of oral Voltaren, this also concerned me because I suffer from Barrett's Syndrome, stomach ulcer and erosions in my small intestine. I am also treating for neck & back pain, hence the oral Voltaren prescription. A couple of years ago, I was treated for a knee injury and was given Voltaren gel. I wonder if it will be OK to use the gel on my back to avoid the side effects to my stomach & sm. intestine or will the gel still interact with the other drugs I already mentioned earlier? I welcome any feedback. Especially from folks who have been in the same situation as I am in. I would also like to hear from anyone who has taken oral Voltaren to describe the side effects. Thanks for your input!
