An Overview of Prilosec and Nexium

Prilosec and Nexium are both proton pump inhibitors (PPIs) that are used to treat gastroesophageal reflux disease (GERD), acid reflux, and other related conditions. They work by reducing the amount of acid produced in the stomach, which can help alleviate symptoms such as heartburn, chest pain, and difficulty swallowing.

Prilosec, which is also known as omeprazole, was first approved by the FDA in 1989. Nexium, which is esomeprazole magnesium, was approved in 2001. Both drugs are available in prescription and over-the-counter (OTC) forms.

The Differences Between Prilosec and Nexium

While Prilosec and Nexium are similar drugs, there are some differences between them that may make one a better choice than the other depending on your individual needs.

Chemical Makeup

Prilosec contains omeprazole, while Nexium is made up of esomeprazole magnesium. The two drugs are structurally similar, but some studies have suggested that esomeprazole may be more effective in reducing acid production than omeprazole.


Prilosec is generally less expensive than Nexium, especially in its OTC form. However, if you have insurance, the cost difference may not be as significant.

Dosage and Administration

The recommended dosage for Prilosec is one 20mg capsule per day, while Nexium is often prescribed at a higher dosage of 40mg per day. Nexium is also available in a delayed-release capsule that is meant to be taken on an empty stomach, while Prilosec can be taken with or without food.

Side Effects

Both Prilosec and Nexium can cause side effects, such as headaches, nausea, and diarrhea. However, Nexium may be associated with a slightly higher risk of bone fractures and infections.

Which is the Better Option?

Ultimately, the choice between Prilosec and Nexium will depend on your individual needs and preferences. If cost is a major factor, Prilosec may be the better choice. However, if you have severe symptoms that are not adequately controlled with Prilosec, Nexium may be a better option.

It is important to talk to your doctor about which medication is right for you, as they can provide personalized recommendations based on your medical history and current symptoms.


Prilosec and Nexium are both effective options for treating GERD and other related conditions. While they have some differences, both drugs work by reducing the amount of acid produced in the stomach. The choice between the two will depend on factors such as cost, dosage, and individual side effects. Talk to your doctor to determine which medication is right for you.
