Is there a possible link between Omeprazole and increased anxiety and fatigued?

Posted , 14 users are following.

For 8 months after finished taking Omeprazole, I been getting heart palpitations and anxiety attacks. I was taking them because of GERD and over counter meds not working, and since then been getting anxiety, that has calmed down now as I manage to control other things that trigger them, i.e hunger, heat stress

Had tests at ER, blood test, sugar test chest x-rays etc. All fine.

But I still get some panic attacks, some days worse than others, some days none.

This month, acid reflux is back, and felt bloated, burping and vonstant indigestion.

Doctor thought it may be multiple things, indigestion, muscle ache from physical work and anxiety attacks.

Doctor prescribed me Omeprazole, and gave me a phone number for a therapist that deals with anxiety, mental health problems.

Ever since I started taking Omeprazole again this week, I feel tired fatigued and drowsy, my anxiety seems to go bad again, heart beats fast and like air stuck in my chest, and feel kinda down, especially when doing nothing, or rainy days, and I get stomach upsets and discomfort too and muscle aches, as if I might got a cold or something.

I read online about the dangers of Omeprazole, but I only take one a day.

Is it a side effect of Omeprazole or is it more likely other things unrelated to antacids?

I tried not taking them today and had no symptoms of indigestion, stomach problems and didn't have anxiety symptoms.
