Omeprazole Nausea Causes and Reviews

Nausea and vomiting are common. Usually, they are not serious. You should see a doctor immediately if you suspect poisoning or if you have

Omeprazole Nausea Reviews

Thu, 15 Nov 2012

Heart palpitating , anxiety and back pain. A little Nausea, loss of appetite. Had taken it before for 14 days a year ago and stopped and was just fine but this time I took only 4 days and symptom started after 3 days... Heart burn is not completely gone either.

Started taking Omeprazole about a month and half ago for acid reflux. After about 3 weeks I started getting hot flashes, Nausea, anxiety, dizzy, mental fuzziness and fatigue.  Every day I just felt sicker and sicker.  Finally put it together that it is
the pill.  Stopping immediately, can't wait for the side affects to wear off!!!

Hi, I know this group hasn't been in discussion for a while now but if anyone could help me out I would appreciate it.
I've been taking Omerprazole for three days (only three days!) because of chest pains I was having that my doctor put down to acid reflux, and I'm already experiencing severe stomach pain during the day and general Nausea when I wake up in the morning. Is this normal? My chest pain is still here, and I don't expect the O to have kicked in yet; so then why is it effecting me so much already if it's not even had a chance to do anything?
I think overall, I would simply like to know if most of you think it's actually worth taking this drug on a daily basis, because all I seem to be doing at the moment is swapping one pain for another without the first one even really abating yet. My chest pains put me in some real agony and it makes it uncomfortable and sometimes impossible to get on with my life normally, but if this is the only solution I feel like I might as well get used to it, because at least I'm not having trouble keeping my food down with a bad chest. Thanks in advance.

Took one Omeprazole caps 1-25-2011, woke up 5am 1-26-2011 with severe abdominal pain and Nausea. Doctors say I have reflux disease, if this is a cure I will stay with the acid reflux.
Thu, 15 Sep 2011
I have been on Omeprazole for about a month for Silent Reflux. It worked for that but I have just been to the doctor because I have been suffering from Nausea, abdominal pain, light headedness, headaches, bloating and the feeling of small explosions in my abdomin which I assume is gas. I get random pains in all different parts of my body that seem to move around then disappear. I generally feel ill and don't want to eat or drink. He has told me to stop taking Omeprazoleiand after 3 days I felt like breakfast this morning. I still have the abdominal pains but hopefully I am getting it out of my system.
