Prilosec is a brand name of the generic omeprazole, a medication that may be prescribed by a doctor or which you may purchase over-the-counter. It is used in the treatment of gastrointestinal problems such as gastroesophageal reflux disease (GERD). Other uses for Prilosec, according to the Mayo Clinic include, are as a treatment for Zollinger-Ellison syndrome, a condition that causes ulcers in the duodenum or small intestines; to prevent damage to the esophagus from acid reflux; and, along with antibiotics, to help in the fight against H. pylori bacterial infection. It is available as a pill or capsule. Taking too much of the drug can lead to overdose.


Taking too much Prilosec can cause a variety of serious overdose symptoms to occur in your body. Any one of these symptoms is serious and requires emergency medical aid, the Mayo Clinic reports, so get to an emergency room at the nearest hospital as soon as possible. One such symptom is that your vision may become blurry. This may not be noticeable at first, but if you try to read something at the normal distance from your eyes and it is blurry, seek help.

Mental Symptoms

There are three potential overdose symptoms associated with Prilosec that can affect your brain, the Mayo Clinic states. The most disconcerting of the three is mental confusion. This could mean confusion about where you are, what you are doing, what the date, day or time are or other such mental difficulties. You also may experience drowsiness as a symptom of an overdose. If you know or suspect you have taken too much omeprazole and you feel abnormally tired, go to the hospital. A headache is another problem that can affect you if you take too much of the medication. If you are not prone to headaches and one occurs after taking a large dose of Prilosec, seek emergency medical aid.

Other Overdose Symptoms

Taking an overdose of omeprazole also can produce other types of symptoms. All of these are just as serious, so get help immediately. These may include vomiting and nausea, dry mouth, excessive sweating, an increased heartbeat, bodily flushing or arrhythmia an irregular heart rate.
