What is Prevacid?

Prevacid (lansoprazole) is a medication that helps reduce the amount of acid in your stomach. It is commonly used to treat conditions like duodenal ulcers and stomach ulcers.

Prevacid is also used with certain antibiotics to treat infections caused by a bacteria called H. pylori, which can lead to ulcers.

Additionally, it is prescribed to maintain the healing of these ulcers and to treat symptoms of gastroesophageal reflux disease (GERD). In this condition, stomach acid flows back into the esophagus and causes heartburn.

Prevacid can also be used for longer-term conditions where the stomach produces too much acid, such as Zollinger-Ellison syndrome, a rare disorder. In children, it treats GERD and esophagitis, which is damage to the esophagus caused by acid.

However, following your doctor’s instructions carefully and not using it longer than prescribed is important.

Prevacid is not recommended for treating GERD in children under one year old due to safety concerns, and it should not be used by individuals who are allergic to its ingredients or certain medications used to treat HIV.

How Does Prevacid Work?

Prevacid works by reducing the amount of acid your stomach makes.

It contains a medicine called lansoprazole, which blocks a specific enzyme in the stomach known as the “proton pump.”

This enzyme produces acid, so when lansoprazole blocks it, the acid levels in your stomach decrease. This helps prevent conditions like heartburn and ulcers, which can be caused by too much acid.

Prevacid works whether your stomach is making acid normally or being stimulated by food or other triggers, making it effective for various acid-related conditions.

Dosage Information and Usage

Dosage Form and Strengths of Prevacid

Prevacid delayed-release capsules:

  • 15 mg: Not currently marketed
  • 30 mg: Pink and black capsule

Prevacid solutab delayed-release orally disintegrating tablets:

  • 15 mg: A round tablet with orange to dark brown speckles
  • 30 mg: A round tablet with orange to dark brown speckles

Usage

Prevacid is used to treat several conditions related to excess stomach acid.

  • For duodenal ulcers, the recommended dose is 15 mg once daily for 4 weeks, with a maintenance dose of 15 mg once daily to prevent recurrence.
  • For gastric ulcers, the dose is 30 mg once daily for up to 8 weeks. When treating gastroesophageal reflux disease (GERD), the dose for symptomatic GERD is 15 mg once daily for up to 8 weeks. For the healing of  erosive esophagitis, 30 mg once daily is used for up to 8 weeks, and longer if necessary.
  • In patients with Zollinger-Ellison syndrome, the starting dose is 60 mg once daily, with potential adjustments up to 90 mg twice daily based on individual needs.
  • For pediatric patients aged 1 to 11 years, those weighing 30 kg or less should take 15 mg once daily, while those over 30 kg should take 30 mg once daily for GERD or erosive esophagitis.
  • For patients aged 12 to 17 years, the dose for non-erosive GERD is 15 mg once daily, and for erosive esophagitis, the recommended dose is 30 mg once daily.

Prevacid should be taken before meals, and capsules should not be crushed or chewed. If a dose is missed, it should be taken as soon as possible, but skipped if the next scheduled dose is near, without doubling doses.

Prevacid can also be administered with soft foods or juices for patients who have difficulty swallowing capsules, following specific instructions for mixing.

Side Effects of Prevacid

Common Side Effects

  • Diarrhea
  • Stomach pain
  • Nausea
  • Constipation

Serious but Rare Side Effects

  • Low vitamin B12 levels (e.g., shortness of breath, lightheadedness, irregular heartbeat, muscle weakness)
  • Fundic gland polyps (stomach growths)
  • Low magnesium levels (e.g., seizures, dizziness, irregular heartbeat, muscle weakness)
  • Severe skin reactions (e.g., blistering, peeling, fever, chills, body aches, enlarged lymph nodes)

Warnings and Precautions

  • Presence of Gastric Malignancy: Prevacid may relieve symptoms, but it does not rule out the possibility of stomach cancer. Additional testing may be necessary for adults with poor or recurring symptoms.
  • Acute Tubulointerstitial Nephritis: Prevacid can cause kidney inflammation, which may happen anytime during treatment. Stop taking it and get checked if kidney issues are suspected.
  • Clostridium difficile-associated Diarrhea: Prevacid may increase the risk of severe diarrhea caused by a bacterial infection, especially in hospitalized patients. Use the lowest dose for the shortest time needed.
  • Bone Fracture: Long-term or high-dose use of Prevacid may raise the risk of bone fractures, especially in the hip, wrist, or spine. Use the lowest dose possible.
  • Severe Skin Reactions: Prevacid can cause serious skin conditions like Stevens-Johnson syndrome. If you notice skin rashes or other severe symptoms, stop using the drug and seek medical help.

Overdosage of Prevacid

If someone takes too much Prevacid, it is not removed from the body through dialysis. In one case, a person took 600 mg of Prevacid without any harmful effects.

In animal studies, extremely high doses (much more than what humans would take) did not cause death or noticeable problems in rats or mice.

If you think you’ve taken too much Prevacid, contact a healthcare provider for guidance, even if you don’t feel any immediate symptoms.

Drug Interactions With Other Medications

  • Antiretrovirals: Prevacid can either decrease or increase the effectiveness of some antiretroviral drugs, like rilpivirine and saquinavir, which can lead to either reduced antiviral effects or increased risk of side effects.
  • Warfarin: Using Prevacid with warfarin may raise the risk of abnormal bleeding due to increased blood thinning, so doctors should monitor your blood clotting levels closely.
  • Methotrexate: When taken together, Prevacid may increase methotrexate levels in the blood, leading to higher risks of side effects, especially with high doses.
  • Digoxin: Prevacid may increase digoxin levels in your blood, so your doctor may need to adjust your dose and monitor drug levels.
  • Theophylline: Prevacid can make the body remove theophylline faster, potentially making the medication less effective, so dosage adjustments may be needed.
  • Drugs dependent on gastric pH for absorption: Prevacid can lower stomach acid, which may affect how well some medications, like iron or antifungal drugs, are absorbed.
  • Combination therapy with clarithromycin and amoxicillin: Taking Prevacid with clarithromycin or amoxicillin may lead to serious reactions or even dangerous heart rhythms.
  • Tacrolimus: Prevacid may increase tacrolimus levels, especially in transplant patients, so regular blood monitoring is necessary.
  • Investigations of neuroendocrine tumors: Prevacid can raise certain hormone levels, potentially leading to false-positive results in tests for neuroendocrine tumors.
  • Secretin stimulation test: Prevacid can cause a high gastrin response during this test, falsely suggesting the presence of a tumor.
  • False positive urine tests for THC: Prevacid may cause false positive results for cannabis in urine drug tests, so further confirmation tests are advised.
  • CYP2C19 or CYP3A4 inducers: Drugs like St. John’s Wort or rifampin can reduce Prevacid’s effectiveness, so they should not be taken together.
  • CYP2C19 or CYP3A4 inhibitors: Drugs like voriconazole can increase Prevacid levels in the body, which might require dose adjustments.
  • Sucralfate: Taking sucralfate can interfere with Prevacid absorption, so it’s recommended to take Prevacid at least 30 minutes before sucralfate.

Frequently Asked Questions

Prevacid is prescribed to treat conditions caused by excess stomach acid, such as gastroesophageal reflux disease (GERD), stomach ulcers, and erosive esophagitis. It works by reducing the amount of acid produced in the stomach.

Prevacid typically stays in your body for about 8 hours before most of it is eliminated.

Prevacid is not an antacid; it is a proton pump inhibitor (PPI). Unlike antacids, which work quickly, Prevacid can take a few days to start working effectively. Your provider might suggest using an antacid, like Tums, alongside Prevacid during this period.

You should avoid taking Prevacid with certain medications and substances. Specifically:
  • Clarithromycin: Can interact with Prevacid and lead to increased side effects.
  • Warfarin: May increase bleeding risk when used with Prevacid.
  • Methotrexate: High doses of methotrexate can interact with Prevacid, potentially causing toxicity.
  • Antiretrovirals: Certain antiretroviral drugs, like rilpivirine and atazanavir, may not work as well with Prevacid.

Prevacid may take 1 to 4 days to fully work and relieve symptoms. It is not meant for immediate relief of heartburn. If you have difficulty swallowing the capsule, you can open it and mix the contents with applesauce, cottage cheese, yogurt, or strained pears.

The best time to take Prevacid is about 30 minutes before eating. This helps ensure the medication works effectively to reduce stomach acid.

Before taking Prevacid during pregnancy, consult with your OB/GYN. Generally, medications that reduce stomach acid, like Prevacid, are considered safe for pregnant patients.

Take Prevacid before a meal. For the full course of treatment, continue taking it even if you start to feel better. If using Prevacid to treat an ulcer linked to an H. pylori infection, take it with the prescribed antibiotics at the same time of day.

Prevacid is available both over the counter (OTC) and by prescription. The OTC strength is 15 mg, while prescription strengths are 15 mg and 30 mg.

Prevacid can be taken long-term, but there are risks associated with extended use. Studies have linked long-term use to serious health issues such as kidney damage and cancer. It’s important to discuss the risks and benefits with your doctor before using Prevacid for an extended period.

Common side effects of Prevacid include headache, diarrhea, constipation, nausea, and stomach pain. More serious side effects can include kidney problems, bone fractures, and vitamin B12 deficiency. If you experience severe symptoms like persistent stomach pain, muscle spasms, or signs of an allergic reaction (such as rash or swelling), contact your doctor immediately.

Yes, you can drink alcohol while taking Prevacid. However, it’s best to limit your alcohol intake because alcohol can increase stomach acid production and potentially worsen your symptoms.

Stopping Prevacid abruptly after taking it for over 8 weeks can lead to increased or “rebound” acid production. This may cause your GERD symptoms to flare up and persist for weeks or even months.

Yes, Prevacid can be used to treat acid reflux. It decreases the amount of acid made by the stomach, helping to manage conditions like ulcers, gastroesophageal reflux disease (GERD), and heartburn.

If you miss a dose of Prevacid, take it as soon as you remember. If it’s almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take two doses at once to make up for the missed dose.

Prevacid is not recommended for children younger than 1 year old, as it may harm them. However, a doctor may prescribe it if they believe the benefits outweigh the risks. If your child is prescribed Prevacid, consult with the doctor for information on its benefits and risks.

Prevacid has been reported to cause weight gain in some cases. However, weight gain is not a common side effect and is more likely to occur with long-term use of the medication.

Yes, Prevacid can be used to treat stomach ulcers. It works by reducing the amount of acid in your stomach, which helps heal ulcers and manage related conditions.

Yes, Prevacid can potentially cause vitamin deficiencies. Some studies suggest that long-term use of proton pump inhibitors like Prevacid may increase the risk of vitamin B-12 deficiency. If you’re concerned about your vitamin B-12 levels, consult your healthcare professional.

  • Inform your doctor of any allergies to medications, particularly to Prevacid.
  • Tell your doctor if you have a history of liver disease, low magnesium levels, or osteoporosis.
  • Long-term use of Prevacid may increase the risk of bone fractures or vitamin B-12 deficiency.
  • Avoid taking Prevacid with certain medications such as warfarin or digoxin unless advised by a doctor.
  • Let your doctor know if you’re pregnant, planning to become pregnant, or breastfeeding.
  • Do not stop taking Prevacid suddenly, as it may cause acid rebound.
