What is the Difference Between Omeprazole and Prevacid?

Omeprazole and Prevacid (lansoprazole) are both proton pump inhibitors (PPIs) used to reduce symptoms of GERD and acid reflux by blocking the amount of acid the stomach produces. They are available in prescription and over-the-counter (OTC) forms, and both are approved for treating the same conditions, including gastroesophageal reflux disease (GERD), esophagitis, and Zollinger-Ellison syndrome.

However, there are some differences between the two medications:

• Brand Names: Omeprazole is widely known as Prilosec, while lansoprazole is known as Prevacid.
• Dosage: The typical prescription dosage for Prevacid is 30 mg once or twice daily, while Prilosec's dosage varies by indication.
• Effectiveness: One study found that Prevacid was slightly more effective at relieving severe heartburn symptoms, but by the end of eight weeks, both medications performed the same.
• Side Effects: Both medications have some common side effects, such as dizziness, headache, nausea, and diarrhea. However, Prevacid may cause additional side effects like fast or irregular heart rate, watery or bloody diarrhea, muscle cramps or weakness, jerky muscle movements, confusion, jitteriness, or seizures.
• User Ratings: Prevacid has a higher average rating (8.0 out of 10) compared to Omeprazole (4.5 out of 10) on Drugs.com, with more users reporting a positive effect.

A healthcare provider can help determine which medication might work best for your health and individual needs.
