Warnings

To treat duodenal (intestinal) ulcers, the recommended adult dose of Prevacid (Lansoprazole) is 15 mg daily, before breakfast, for 2 to 4 weeks. For duodenal ulcers that return, Prevacid (Lansoprazole) may be used for up to one year.

To treat gastric (stomach) ulcers, the recommended adult dose of Prevacid (Lansoprazole) is 15 mg daily, before breakfast, for 4 to 8 weeks. The usual recommended dose to treat gastric ulcers caused by NSAIDs is 15 mg to 30 mg daily, before breakfast, for up to 8 weeks. When used to reduce the risk of gastric ulcers for people who are taking NSAIDs, the usual dose is 15 mg daily, before breakfast, for up to 12 weeks.

To treat duodenal ulcers caused by H. pylori bacteria (as confirmed by a test), the recommended dose of Prevacid (Lansoprazole) is 30 mg along with clarithromycin 500 mg and amoxicillin 1,000 mg, all taken twice daily for 7, 10, or 14 days. All of these medications should be taken before meals. This combination of medications helps kill the bacteria that can cause duodenal ulcers.

To treat GERD and associated heartburn symptoms, the recommended dose of Prevacid (Lansoprazole) is 15 mg daily before breakfast for up to 8 weeks. Doses up to 30 mg daily are sometimes prescribed for reflux esophagitis or other conditions associated with increased secretion of acid by the stomach.

To treat GERD in children 1 to 11 years of age, the recommended dose is 15 mg to 30 mg (depending on the child's weight) once daily for up to 12 weeks. An increase in dose may be beneficial for some children. For adolescents 12 to 17 years old who have GERD, the adult dose can be used.

When treating Zollinger-Ellison syndrome or other conditions which overproduce stomach acid, the dose of Prevacid (Lansoprazole) varies, but is often higher than the doses used to treat ulcers. Doses larger than 60 mg daily are often needed.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

Prevacid (Lansoprazole) should be taken before breakfast or, if taken twice daily, before breakfast and another meal. The medication should not be crushed or chewed. The capsules should be swallowed whole with a glass of water. People who have difficulty swallowing capsules may open the capsule and sprinkle its contents on a tablespoon of applesauce, which should then be immediately swallowed.

Prevacid (Lansoprazole) fast dissolving tablets should not be chewed or cut. They should not be swallowed whole; they should be placed on the tongue for about one minute to allow the tablet to dissolve. Once the tablet has dissolved, the particles can be swallowed. Alternatively, for adults and children who have trouble swallowing, the tablet may be dissolved in an oral syringe with water. Speak to your pharmacist for specific directions.

It is important to take Prevacid (Lansoprazole) exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store Prevacid (Lansoprazole) at room temperature, protect it from light and moisture, and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:

stop taking one of the medications,
change one of the medications to another,
change how you are taking one or both of the medications, or
leave everything as is.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Medications other than those listed above may interact with Prevacid (Lansoprazole). Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the Nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.

Before you begin taking a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should take Prevacid (Lansoprazole).

Diarrhea: When gastric acid is decreased, the number of bacteria normally in the digestive system increases. Occasionally, this can cause serious infection in the digestive tract. If you experience severe watery or bloody diarrhea, fever, or abdominal pain while taking Prevacid (Lansoprazole), contact your doctor as soon as possible.

Electrolyte balance: Long term use of Prevacid (Lansoprazole) may cause the levels of electrolytes such as magnesium, calcium, and potassium in the blood to decrease. If you experience symptoms of fluid and electrolyte imbalance such as muscle pains or cramps; dry mouth; numb hands, feet, or lips; or racing heartbeat, contact your doctor as soon as possible. Your doctor may do blood tests periodically to monitor the levels of these electrolytes in your blood while you are taking Prevacid (Lansoprazole).

Liver function: Decreased liver function may cause Prevacid (Lansoprazole) to build up in the body. If you have reduced liver function or liver disease, discuss with your doctor how Prevacid (Lansoprazole) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Prevacid (Lansoprazole), and whether any special monitoring is needed.

If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.

Methotrexate interaction: Prevacid (Lansoprazole), like other medications in this group, may interact with methotrexate when the two medications are used at the same time. This combination may lead to higher than expected amounts of methotrexate in the body and can cause serious side effects, including kidney damage, irregular heartbeat, Anemia, or infection. If you take Prevacid (Lansoprazole) and are also going to receive a dose of methotrexate, discuss with your doctor how Prevacid (Lansoprazole) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Prevacid (Lansoprazole), and whether any special monitoring is needed.

More serious conditions of the stomach and intestines: Even if you experience improvement in acid-related symptoms, it is still possible to have serious underlying stomach problems such as stomach cancer. If you experience symptoms of a more serious condition of the stomach and intestines (e.g., trouble swallowing, unplanned weight loss, vomiting of blood or food, or black stools) while taking Prevacid (Lansoprazole), contact your doctor immediately.

Osteoporosis fractures: Long-term use of Prevacid (Lansoprazole) may be related to an increased risk of bone fractures in the hip, wrist, or spine, as a result of weakened bones. This risk is further increased if you are at risk of developing osteoporosis. If you have osteoporosis or have risk factors for developing osteoporosis, discuss with your doctor how Prevacid (Lansoprazole) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Prevacid (Lansoprazole), and whether any special monitoring is needed.

Vitamin B12: Long-term use of Prevacid (Lansoprazole) may lead to vitamin B12 deficiency. If you are a vegetarian or have low vitamin B12 levels, discuss with your doctor if any special monitoring is required.

Pregnancy: There are no adequate or well-controlled studies on the use of Prevacid (Lansoprazole) by pregnant women. Prevacid (Lansoprazole) should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking Prevacid (Lansoprazole), contact your doctor immediately.

Breast-feeding: It is not known if Prevacid (Lansoprazole) passes into breast milk. If you are a breast-feeding mother and are taking Prevacid (Lansoprazole), it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of Prevacid (Lansoprazole) have not been established for use by children under one year old. For children 1 to 17 years old, Prevacid (Lansoprazole) can be used to treat GERD for a maximum of 12 weeks.
