Prevacid (lansoprazole) Disease Interactions

There are 4 disease interactions with Prevacid (lansoprazole):

Major

PPIs (Includes Prevacid) ↔ C. diff

Severe Potential Hazard, Moderate plausibility. Applies to: Pseudomembranous Colitis, Diarrhea

Published observational studies suggest that proton pump inhibitor (PPI) use may be associated with an increased risk of Clostridium difficile-associated diarrhea (CDAD), especially in hospitalized patients. This diagnosis should be considered for diarrhea that does not improve. It is recommended that patients should use the lowest dose and shortest duration of PPI therapy appropriate to the condition being treated. Close monitoring is recommended in patients with diarrhea and in those taking antibacterial agents as CDAD has been reported with the use of nearly all these agents. Treatment with antibacterial agents alters the normal flora of the colon, leading to overgrowth of C. difficile. C. difficile produces toxins A and B, which contribute to the development of CDAD. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated.

Moderate

Lansoprazole (Includes Prevacid) ↔ liver disease

Moderate Potential Hazard, Moderate plausibility. Applies to: Liver Disease

Lansoprazole is primarily metabolized by the liver. Although the drug is generally well-tolerated, dosage adjustments with cautious titration should be considered in patients with severe hepatic impairment.

Moderate

Proton pump inhibitors (Includes Prevacid) ↔ bone fractures

Moderate Potential Hazard, Moderate plausibility. Applies to: Osteoporosis

Various published observational studies have reported that PPI therapy may be associated with an increased risk for osteoporosis related fractures of the hip, wrist or spine. The risk was increased in patients who received high doses (multiple daily doses), and long term treatment (a year or longer). Patients should use the lowest dose and shortest duration of PPI therapy appropriate to the condition being treated. Caution should be used in patients at risk for osteoporosis related fractures and should be managed according to established treatment guidelines.

Moderate

Proton pump inhibitors (Includes Prevacid) ↔ hypomagnesemia

Moderate Potential Hazard, Moderate plausibility. Applies to: Magnesium Imbalance

Symptomatic and asymptomatic hypomagnesemia has been reported rarely in patients treated with PPIs for at least 3 months, in most cases after a year of therapy. Serious adverse events can include tetany, seizures, and arrhythmias. Caution should be used in patients prone to magnesium imbalances such as patients taking other medications that can cause hypomagnesemia (e.g., diuretics). Regular monitoring is recommended.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No information available.

Do not stop taking any medications without consulting your healthcare provider.
