How Lansoprazole works
Lansoprazole blocks the final step in the stomach’s production of gastric acid. This drug accomplishes this by suppressing the enzyme system in the stomach’s lining. The enzyme system is called an “acid pump” or “proton pump.” This is why lansoprazole is also called a proton pump inhibitor(PPI). Within one to two hours, the stomach’s acid level is measurably lower with 30mg of Prevacid.
Storage, dosage, and how to use Lansoprazole
Prevacid Solutab comes in liquid form, capsules, and tablets. Do not freeze the oral suspension Prevacid Solutab. Capsules and tablets come in 15mg and 30mg doses. Keep the bottles at room temperature and away from any possible heat, moisture and light.
The first dose of the day is taken before eating, preferably in the morning before eating breakfast. Shake the liquid before measuring the dose. Use the provided dosing syringe. Or use another precise dose-measuring device rather than a kitchen spoon. The dose needs to be accurate. Depending on the diagnosis treated, the Provider writes the dosing. Dosing is typically 15mg once a day before the first meal, for eight weeks.
Swallow the capsules and tablets whole, do not crush, chew, break, or open them.
Remove the orally disintegrating tablet from the package only when you can take it immediately. Allow the tablet to dissolve inside the mouth. Do not chew. Swallow as many times as necessary as the tablet continues to dissolve.

Warnings & Precautions
WARNING – Heartburn mimics early heart attacks symptoms. Contact emergency services if you experience chest pain that spreads to your jaw or shoulder. Also get emergency help if you begin to feel anxious, lightheaded, or have difficulty breathing.
WARNING – Experiencing a positive result of using Prevacid, does not mean the problem’s source is resolved. Follow up tests for gastric ulcers and cancer are advised.
Because body fluid levels are influenced by how foods digest, some patients may hold fluids. Bodily fluid may cause uncomfortable symptoms, like swelling, or create conditions that enable bacteria growth in the kidney or bladder. A small number of patient develop chronic kidney conditions. For this reason, the FDA’s position statement is to only use Lansoprazole as indicated and prescribed. Do not use PPIs for simple heartburn or indigestion.
Prevacid, and other medicines like it, are associated with a severe diarrhea caused by bacteria called Clostridium difficile. Call the prescribing Provider if watery or bloody diarrhea occurs. Discontinue use of Prevacid until further labs are completed.
In some cases, Prevacid may cause worsening symptoms of Lupus. Report joint pain and a skin rash on cheeks and arms that worsens in sunlight.
When taking Prevacid Solutab long term or more than once a day, your bones may break more easily.
VITAMIN B12 DEFICIENCY
Long term use of Prevacid/Lansoprazole can lead to B12 deficiency. Because the stomach’s acidity is decreased, the stomach is unable to absorb this necessary vitamin from food. Long term use is three years or more.
MAGNESIUM AND MINERAL DEFICIENCY
Long term use of Prevacid may cause low levels of Magnesium and minerals.
If any of the following conditions are in your health history, tell the Prescribing Provider:
- liver disease
- low blood levels of magnesium
- osteoporosis or osteopenia
Do NOT use Prevacid without the advice of a doctor, if you have or have ever had:
- trouble or pain with swallowing
- bloody or black stools
- vomit that looks like blood or coffee grinds
- heartburn lasting more than 3 months
- frequent chest pain
- heartburn with wheezing
- unexplained weight loss
- nausea or vomiting
- stomach pain
- electrolyte imbalance or metabolic disorder
Short-term use of lansoprazole causes few side effects. Long term use of this medication is more likely to cause adverse effects.
Do not use this drug with any medication that contains rilpivirine.
Drugs to report to the prescribing Provider before taking Lansoprazole :
- long-term corticosteroid medications
- other proton pump inhibitors
- anti-HIV medications – atazanavir, rilpivirine, saquinavir, or tipranavir
- any medication that lowers magnesium levels
- anticancer medications
- antifungal medications
Some drugs, like sucralfate, interfere with absorption of lansoprazole. Methotrexate needs to be reported to the Prescriber to monitor possible liver damage from taking both drugs at the same time. If using Prevacid for a stomach ulcer, avoid anti-inflammatory painkillers, such as ibuprofen and aspirin.
Many other drugs, over-the-counter medications, vitamins, and herbal supplements interfere with Prevacid. Some decrease its efficacy; others cause dangerous conditions in the body. Ginkgo biloba and St John’s wort, for example, make Prevacid less effective. Taken with warfarin, Prevacid increases bleeding and can hasten death.
Recognise that products as simple as fish oil taken with Prevacid cause unwanted side effects. The above list is not comprehensive. Review all medications, supplements, and herbs with your prescribing provider to learn what can and cannot be taken while taking Prevacid. Keep your Medication pamphlet in an easy-to-find location and read it when in doubt.
