People may take over-the-counter Prilosec to help them prevent indigestion and heartburn. Doctors may prescribe the generically named omeprazole to help treat more serious problems such as gastroesophegeal reflux disease and ulcers. They may prescribe it in combination with antibiotics in the treatment of ulcers caused by the helicobacter pylori bacteria as well. The medication functions to reduce stomach acid production. MayoClinic.com reports that serious side effects from Prilosec use are uncommon.
Diarrhea
The most common non-serious side effect of taking Prilosec is diarrhea, notes Drugs.com. The medication reduces stomach acid production, which can cause a change in the digestive system lower down in the intestines. Because diarrhea is classified as a non-serious side effect, it should not continue for an extended period or be a severe problem. A physician should be consulted if the diarrhea becomes a problem.
Abdominal Pain
MayoClinic.com reports that Prilosec can cause some initial stomach pain. This common, non-serious side effect of the drug most often occurs during initial use, but typically stops without medical treatment.
Headaches
Like many new medication introduced into the body, Prilosec can cause headaches during the first stage of use, Drugs.com indicates. Headaches can occur with any form of the drug, whether taken as a pill, capsule or suspension.
Nausea and Vomiting
Many medications, including Prilosec, can cause nausea and vomiting during first use because the body needs time for the adjustment to the medicine. In most cases, nausea and vomiting will occur as mild problems, but Drugs.com indicates patients should seek medical aid if these side effects become severe or do not stop.
