What is lansoprazole?

Lansoprazole is a proton-pump inhibitor (PPI) used to reduce the amount of acid your stomach produces. It’s commonly prescribed for conditions related to excess stomach acid, such as:

  • Gastroesophageal reflux disease (GERD)
  • Stomach and duodenal ulcers
  • Erosive esophagitis (inflammation of the esophagus)
  • Zollinger-Ellison syndrome (a rare condition with high acid production)

Lansoprazole is typically taken once daily, about 30 to 60 minutes before a meal. It’s available as a capsule, orally disintegrating tablet, or liquid.

How does lansoprazole work?

Lansoprazole works by blocking an enzyme in the stomach lining called the “proton pump”, which is responsible for secreting stomach acid. By inhibiting this pump, lansoprazole helps decrease acid levels. This gives the esophagus, stomach, and intestine time to heal and reduces symptoms like heartburn or acid regurgitation.

How do I know if I qualify for lansoprazole?

You may qualify for lansoprazole if you experience any of the following:

  • Frequent heartburn or acid reflux (especially if it's occurring more than twice a week)
  • A diagnosed case of GERD (gastroesophageal reflux disease)
  • Stomach or duodenal ulcers
  • Damage to your esophagus from stomach acid (e.g., erosive esophagitis)
  • A rare condition like Zollinger-Ellison syndrome, which causes excess acid production

A healthcare provider can help determine if lansoprazole is appropriate based on your symptoms, test results, and treatment history.

Frequently
Asked
Questions

How do I know if lansoprazole is right for me?

Lansoprazole may be right for you if you have frequent heartburn, acid reflux, ulcers, or a diagnosed condition like GERD and need more than just occasional antacids. It’s best for people who need consistent acid control. A consultation with a healthcare provider can confirm if it’s appropriate based on your symptoms and medical history.

Who should not take lansoprazole?

You should not take lansoprazole if you’ve had an allergic reaction to it or any proton pump inhibitor (like omeprazole or esomeprazole). It may also not be right for you if you have:

  • Severe liver disease
  • A history of low magnesium or vitamin B12 levels
  • Osteoporosis or are high risk for bone fractures
  • Infections like C. difficile, especially if you’ve had gut issues from antibiotics

Always be sure to check with your provider, especially if you're taking other medications that interact with acid levels or affect nutrient absorption.

Can you take lansoprazole more than once a day?

The typical dosage for lansoprazole is once daily. In some cases, a healthcare provider may recommend taking lansoprazole twice a day. Be sure to follow your provider’s dosage schedule for safety and effectiveness.

Is lansoprazole an antacid?

No, lansoprazole is not an antacid. It's a proton pump inhibitor (PPI), which works by reducing the amount of acid your stomach produces over time.

Antacids, like Tums or Rolaids, neutralize existing stomach acid and provide quick, short-term relief. Lansoprazole, on the other hand, takes longer to start working but provides longer-lasting control by targeting the acid production at its source.

If you need fast relief, an antacid may help temporarily – but for ongoing issues like GERD or ulcers, lansoprazole is often the more effective option when prescribed.

Is lansoprazole the same as omeprazole?

Lansoprazole and omeprazole belong to the same class of medications (proton-pump inhibitors), but they are different drugs. Their main differences lie in their chemical structure, how quickly they’re absorbed, and how long they last in the body.

For most people, they work equally well. Some may respond better to one than the other, or experience fewer side effects. Your provider can help determine which one may be a more suitable treatment for your needs.

What are the most common side effects of lansoprazole?

The most common side effects of lansoprazole are usually mild and may include:

  • Headache
  • Diarrhea
  • Stomach pain
  • Nausea
  • Constipation
  • Gas or bloating
  • Dizziness

These typically go away on their own. If they persist or worsen, or if you experience more serious symptoms like severe diarrhea, muscle cramps, or signs of an allergic reaction, you should contact your healthcare provider.
