What is the most important information I should know about lansoprazole?

Lansoprazole can cause kidney problems. Tell your doctor if you are urinating less than usual, or if you have blood in your urine.

This medicine can cause diarrhea, which may be a sign of a new infection. Call your doctor if you have diarrhea that is watery or has blood in it.

Taking a proton pump inhibitor such as lansoprazole may increase your risk of bone fracture in the hip, wrist, or spine.

What is lansoprazole?

Lansoprazole is a proton pump inhibitor. Lansoprazole decreases the amount of acid produced in the stomach.

Lansoprazole is used to treat and prevent stomach and intestinal ulcers, erosive esophagitis (damage to the esophagus from stomach acid), and other conditions involving excessive stomach acid such as Zollinger-Ellison syndrome.

Over-the-counter lansoprazole (Prevacid OTC) is used to treat frequent heartburn that happens 2 or more days per week.

Lansoprazole is not for immediate relief of heartburn symptoms.

Lansoprazole may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking lansoprazole?

Heartburn can mimic early symptoms of a heart attack. Get emergency medical help if you have chest pain that spreads to your jaw or shoulder and you feel anxious or light-headed.

You should not use this medicine if you are allergic to lansoprazole, or if you take any medicine that contains rilpivirine (Edurant, Complera, Odefsey).

Tell your doctor if you have ever had:

  • liver disease;
  • lupus;
  • low levels of magnesium in your blood; or
  • osteoporosis or low bone mineral density (osteopenia).

Do not use over-the-counter lansoprazole (Prevacid OTC) without the advice of a doctor if you have:

  • trouble or pain with swallowing;
  • bloody or black stools; vomit that looks like blood or coffee grounds;
  • heartburn that has lasted for over 3 months;
  • frequent chest pain, heartburn with wheezing;
  • unexplained weight loss;
  • nausea or vomiting, stomach pain; or
  • an electrolyte imbalance or metabolic disorder.

Some forms of lansoprazole may contain phenylalanine. Tell your doctor if you have phenylketonuria (PKU).

Taking a proton pump inhibitor such as lansoprazole may increase your risk of bone fracture in the hip, wrist, or spine. This effect has occurred mostly in people who have taken the medication long term or at high doses, and in those who are age 50 and older. It is not clear whether lansoprazole is the actual cause of an increased risk of fracture.

Some conditions are treated with a combination of lansoprazole and antibiotics. Use all medications as directed by your doctor

Do not give lansoprazole to a child younger than 1 year old. Prevacid OTC is not approved for use by anyone younger than 18 years old.

Ask a doctor before using this medicine if you are pregnant or breast-feeding.

How should I take lansoprazole?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Lansoprazole is usually taken before eating. Prevacid OTC should be taken in the morning before you eat breakfast.

Shake the oral suspension (liquid) before you measure a dose. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

Swallow the capsule whole and do not crush, chew, break, or open it.

Remove an orally disintegrating tablet from the package only when you are ready to take the medicine. Place the tablet in your mouth and allow it to dissolve, without chewing. Swallow several times as the tablet dissolves.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.

Use this medicine for the full prescribed length of time, even if your symptoms quickly improve.

Prevacid OTC should be taken only once daily for 14 days. It may take up to 4 days for full effect. Allow at least 4 months to pass before you start another 14-day treatment with Prevacid OTC.

Call your doctor if your symptoms do not improve or if they get worse while you are taking lansoprazole. If you take Prevacid OTC, call your doctor if your heartburn gets worse over the 14-day treatment, or if you need treatment more than once every 4 months.

If you use lansoprazole for longer than 3 years, you could develop a vitamin B-12 deficiency. Talk to your doctor about how to manage this condition if you develop it.

Store at room temperature away from moisture, heat, and light. Do not freeze the liquid medicine.

What happens if I miss a dose?

Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

What should I avoid while taking lansoprazole?

This medicine can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, call your doctor before using anti-diarrhea medicine.

What are the possible side effects of lansoprazole?

Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if you have:

  • severe stomach pain, diarrhea that is watery or bloody;
  • new or unusual pain in your wrist, back, hip, or thigh;
  • a seizure (convulsions);
  • irregular heartbeats;
  • kidney problems --little or no urination, blood in your urine, swelling, rapid weight gain; or
  • new or worsening symptoms of lupus --joint pain, and a skin rash on your cheeks or arms that worsens in sunlight.

Common side effects may include:

  • nausea, stomach pain;
  • diarrhea, constipation; or
  • headache.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

What other drugs will affect lansoprazole?

Sucralfate (Carafate) can make it harder for your body to absorb lansoprazole. Wait at least 30 minutes after taking lansoprazole before you take sucralfate.

Sometimes it is not safe to use certain medications at the same time. Some drugs can affect your blood levels of other drugs you take, which may increase side effects or make the medications less effective.

Many drugs can affect lansoprazole, and some drugs should not be used at the same time. This includes prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed here. Tell your doctor about all your current medicines and any medicine you start or stop using.

Where can I get more information?

Your pharmacist can provide more information about lansoprazole.


Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use this medication only for the indication prescribed.
