Applies to: famotidine and Bonisara (cyanocobalamin / folic acid / pyridoxine / strontium gluconate)

By reducing or suppressing gastric acid secretion, H2-receptor antagonists and proton pump inhibitors may interfere with the gastrointestinal absorption of vitamin B12, a process that is dependent on the presence of gastric acid and pepsin. Clinical studies have shown that dietary (i.e., protein-bound) vitamin B12 malabsorption can occur during treatment with these agents, particularly proton pump inhibitors, although the likelihood of developing clinically significant deficiency over time is unknown. There has been one reported case of vitamin B12 deficiency with megaloblastic anemia in a patient who received omeprazole at a minimum of 40 mg/day for 4 years. Also uncertain is whether acid reduction or suppression can affect the absorption of vitamin B12 ingested in the form of oral supplements such as cyanocobalamin. Non-oral routes of administration (e.g., parenteral, intranasal, sublingual) are generally preferred in the treatment of B12 deficiency-related anemia.

Drug and food interactions

Moderate

folic acid food

Applies to: Bonisara (cyanocobalamin / folic acid / pyridoxine / strontium gluconate)

MONITOR: Ethanol may increase folic acid elimination and folic acid absorption is decreased in chronic alcoholics. Excessive alcohol consumption may lead to folate deficiency.

MANAGEMENT: Monitoring of patient response to folic acid supplementation if they also consume alcohol regularly may be recommended.

Moderate

strontium gluconate food

Applies to: Bonisara (cyanocobalamin / folic acid / pyridoxine / strontium gluconate)

ADJUST DOSING INTERVAL: Concomitant administration of strontium with food or milk products may decrease its bioavailability by 60% to 70%.

MANAGEMENT: Strontium salts should be taken at least two hours before or two hours after food or milk products, and preferably at bedtime.

famotidine food

Applies to: famotidine

H2 antagonists may reduce the clearance of nicotine. Cimetidine, 600 mg given twice a day for two days, reduced clearance of an intravenous nicotine dose by 30%. Ranitidine, 300 mg given twice a day for two days, reduced clearance by 10%. The clinical significance of this interaction is not known. Patients should be monitored for increased nicotine effects when using the patches or gum for smoking cessation and dosage adjustments should be made as appropriate.

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.
