I had a mild case of laryngophrayngeal reflux (reflux into the larynx) with no heartburn. My PCP prescribed 20 mg Omeprazole to be taken once a day. I experienced terrible muscle numbness, nausea, gas, burping, fatigue, lightheadness, anxiety and depression. I stopped after 6 days. The symptoms continued. After another 6 days, I had a panic attack and went to the ER. It has been over 20 days since I stopped this awful medication. I still cannot eat normally. I now experience heartburn after almost every meal. I still feel light headed and disconnected with the world. I tracked down the manufacturer of the Omeprazole that I took by asking my pharmacist. The manufacturer's rep wrote up a side effects report for the FDA with my consent. I urge everyone to do the same. You can also contact the FDA directly. This is the only way that we can force the FDA and the drug industry to retest the safety of this drug. Best wishes to all.
