Hello,
I understand you are concerned about any interactions between your medications, and especially if any can cause weight gain. Of all your medications, the only serious interaction is between
Omeprazole and Clopidogrel; there has been concern that Omeprazole interferes with Clopidogrel, which as you may know is a blood thinner to protect you from any more heart attacks.
However, the evidence is not clear that Omeprazole actually causes any problems, and so I would not say you absolutely should stop Omeprazole. I recommend you make sure your doctor knows you are taking both these medications, and if Omeprazole is not necessary perhaps it could be stopped.
As far as I know, none of your medications cause significant weight gain. Most often weight gain is due to changes in diet, activity level, or
metabolism. Perhaps since having your heart attack your activity level has not been what it used to be, and this might explain in part the weight gain.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Aaron Branch,
General & Family Physician
