Q: When can a patient expect Prilosec OTC to start working for frequent heartburn?*
A:
Prilosec OTC begins to work on the very first day of treatment. In fact, clinical studies showed that after taking the first dose of their 14-day course of Prilosec OTC, about half of the people were free of heartburn in the first 24 hours, compared with a significantly lower number of people taking placebo. And over a 14-day course of treatment, an increasing number of people taking Prilosec OTC reported complete heartburn relief.

Q: How is Prilosec OTC different from other many over-the-counter (OTC) heartburn products?
A:
Prilosec OTC works differently from many other OTC heartburn products, such as antacids and other acid reducers. Prilosec OTC stops acid production at the source — the acid pumps that produces stomach acid. Prilosec OTC is to be used once a day (every 24 hours) every day for 14 days for treating frequent heartburn.

Q: Is Prilosec OTC the same as prescription Prilosec (Omeprazole)?
A:
Prilosec OTC delivers the same medicine at the same dose as 20-mg prescription Prilosec. Prilosec OTC is available over the counter and is indicated for people with frequent heartburn. Prilosec OTC is to be used once a day (every 24 hours) every day for 14 days, unless directed otherwise by your doctor.

Q: What is frequent heartburn, and how will a patient know it if they have it?
A:
Frequent heartburn means heartburn two or more days a week. If someone regularly takes acid reducers or antacids for his or her heartburn symptoms, that person may have frequent heartburn.

Q: How should a patient take Prilosec OTC?
A:
As part of a course of therapy, a patient takes only one pill a day to treat frequent heartburn for 24 hours.** One pill a day is taken with a glass of water before eating in the morning for 14 days. The patient may repeat this 14-day treatment every 4 months, or as directed by his or her doctor.

Q: Are there any side effects?
