Prevacid (lansoprazole) is a proton pump inhibitor (PPI). Doctors may recommend it for short-term treatment of ulcers and acid reflux. Studies have linked long-term Prevacid use with several serious side effects. Prevacid users have filed lawsuits over complications from the drug.
If you took a Proton Pump Inhibitor (PPI) like Prevacid or Nexium and suffered kidney damage or injuries, you may be entitled to compensation.
Prevacid (lansoprazole) belongs to a class of drugs called proton pump inhibitors (PPIs). These are powerful heartburn drugs.
The U.S. Food and Drug Administration approved Prevacid in 1995. Prevacid is available in prescription and over-the-counter (OTC) versions.
Recent studies link Prevacid to several serious health risks, especially when taken long-term. Some of the risks associated with Prevacid can result in serious injury or death. These include kidney damage and cancer.
Patients have filed Prevacid lawsuits after suffering severe side effects.
People should speak with their doctors before starting or stopping Prevacid.
Prevacid treats certain problems related to excess stomach acid. It is generally intended for short-term use — anywhere from 10 days to 12 weeks. But patients sometimes use it for longer periods of time.
Prevacid is not meant for quick relief of heartburn. It takes up to four days to relieve symptoms.
Lansoprazole is the active ingredient in Prevacid. It is not effective at treating symptomatic GERD in infants.
Prevacid decreases the amount of acid in the stomach. It blocks an enzyme in the stomach wall responsible for producing the acid. This prevents proton pumps in the stomach from releasing acid.
Decreased stomach acid gives the stomach and esophagus time to heal. It also prevents further damage and complications. This can prevent ulcers from developing or recurring.
Prevacid is a PPI, like Nexium and Prilosec. PPIs differ from H2 blockers like Zantac and Pepcid.
Both types of medication prevent the stomach from producing too much acid. But they do it in different ways.
Prevacid affects tiny proton pumps that generate acid through a chemical process. Zantac prevents acid-producing cells from responding to histamines in the stomach.
Zantac is advertised to work in as little as 30 minutes. Prevacid can take days and multiple doses to take effect.
Studies have linked Prevacid and other PPIs to several serious side effects. PPI side effects are most common with long-term use lasting a year or more.
The FDA has issued several Prevacid warnings since 2010.
Short-term Prevacid use does not usually cause side effects. When side effects do occur, they are typically mild.
Side effects people should ask their doctors about include abnormal heartbeat, muscle pain, leg cramps, weakness and nervousness. Other side effects may be more common.
People who suffered kidney problems have filed Prevacid lawsuits. The cases are among more than 4,200 lawsuits over several different PPIs.
A federal panel combined the lawsuits in a multidistrict litigation. MDLs allow several similar lawsuits to move more quickly through the legal process. The cases are in New Jersey federal court.
People take Prevacid orally. It is available in delayed-release capsules and delayed-release orally disintegrating tablets.
Patients can swallow the delayed-release capsules whole. People place the disintegrating tablets on the tongue and allow them to dissolve with or without water.
Patients should take either version before a meal. People should not crush either form of the medicine.
Prevacid comes in several forms. Over-the-counter and generic prescription versions are available. There are also store brand equivalents. All forms contain the same active ingredient, lansoprazole.
Prescription Prevacid versions come in both 15 mg and 30 mg pills. Prevacid 24 HR comes in 15 mg pills.
Dosages can vary based on the condition Prevacid treats. Doctors may also consider the age and weight of the patient. Doctors may adjust the dosage depending on the patient’s other health conditions.
The recommended daily dosage of Prevacid in people with liver disease is 15 mg.

Several recent studies have associated side effects with PPI use in infants. A 2017 study found Prevacid given before a child’s first birthday increased bone fracture risks. And a 2018 study found PPIs taken in infancy can lead to childhood allergies.
It may be possible to overdose on Prevacid. But a case study found a person who took 20 times the adult dose suffered no adverse reactions.
Tests on rats and mice found no relative overdose risk at 1,300 times the adult dose. Overdose symptoms may include passing out or trouble breathing.
“If over-exposure occurs, call your poison control center at 1-800-222-1222 for current information on the management of poisoning or over-exposure. ”
If a person misses a Prevacid dose, he or she should take a dose as soon as possible. If the person is nearing the time for the next dose, he or she may wait until the next scheduled time.
Prevacid is available by prescription or over-the-counter (OTC). Prevacid 24HR is the non-prescription version.
Studies have found that Prevacid 24HR often works as well as prescription Prevacid. Prevacid 24HR is only available in a 15 mg dose.
People can take one Prevacid 24HR 15 mg pill daily for 14 days. Prevacid 24HR users should not take the drug for more than 14 days. They should wait at least four months before taking Prevacid 24HR again.
People who are allergic to lansoprazole should not take Prevacid. People allergic to any other PPI or other Prevacid ingredient should avoid it.
Ingredients vary with each Prevacid version. Check label ingredients for allergies before taking Prevacid.
Women who are pregnant or breastfeeding should consult their doctor before taking Prevacid or any other medication.
Prevacid interactions can happen with 290 other drugs or dietary supplements. People should tell their doctor what drugs they take before starting Prevacid.
Some Prevacid interactions can happen with things as common as aspirin or fish oil.
