Interactions between your drugs

Moderate

naproxen lansoprazole

Applies to: Prevacid NapraPAC (lansoprazole / naproxen) and Prevacid NapraPAC (lansoprazole / naproxen)

GENERALLY AVOID: Theoretically, proton pump inhibitors may decrease the gastrointestinal absorption of enteric-coated naproxen, which requires an acidic environment for dissolution. The proposed mechanism is an increase in gastric pH (i.e. decreased gastric acidity) induced by proton pump inhibitors. In patients treated with proton pump inhibitors, the possibility of a reduced or subtherapeutic response to enteric-coated naproxen should be considered.

MANAGEMENT: Concomitant use of these drugs is generally not recommended.

Moderate

sucralfate lansoprazole

Applies to: sucralfate and Prevacid NapraPAC (lansoprazole / naproxen)

ADJUST DOSING INTERVAL: Coadministration with sucralfate may delay absorption and reduce the bioavailability of lansoprazole by as much as 30%. The exact mechanism of the interaction is unknown, but may involve adsorption of lansoprazole to sucralfate in the gastrointestinal tract.

MANAGEMENT: Some authorities recommend giving lansoprazole at least 1 hour before or after sucralfate administration.

Minor

naproxen sucralfate

Applies to: Prevacid NapraPAC (lansoprazole / naproxen) and sucralfate

Coadministration of naproxen with cholestyramine or sucralfate may delay the absorption of naproxen but not the extent of absorption. The clinical significance is unknown.

Drug and food interactions

Moderate

sucralfate food

Applies to: sucralfate

ADJUST DOSING INTERVAL: The administration of sucralfate with enteral nutrition may result in precipitation and the formation of bezoars that may obstruct feeding tubes. The proposed mechanism is the formation of an insoluble aluminum-protein complex between the aluminum in the sucralfate and the protein in the enteral feeding. In addition, sucralfate may not become activated due to the alkaline pH of enteral nutrition products.

MANAGEMENT: Some experts recommend separating the sucralfate doses from enteral feedings by at least 1 hour. Alternatively, consideration may be given to proton pump inhibitors or H2 antagonists.

Moderate

naproxen food

Applies to: Prevacid NapraPAC (lansoprazole / naproxen)

GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.

MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
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 interaction information available.
