Omeprazole Side Effects

Omeprazole is the generic name for the brand drug Prilosec. The medication is prescribed to treat conditions that have to do with the esophagus, stomach and intestines. This includes gastroesophageal reflux disease (GERD), H. pylori infections and particular ulcers. Omeprazole works to reduce the amount of acid in a person's stomach resulting in heartburn. Prilosec capsules are available by prescription and taken up to two times daily. There is also Prilosec OTC (over-the-counter), which is available without a prescription. Such as the case with most medications, there are a number of possible side effects that Omeprazole may cause.
