Interactions between your drugs

Major

calcium carbonate vadadustat

Applies to: Acid Controller Complete Dual Action (calcium carbonate / famotidine / magnesium hydroxide) and vadadustat

Consumer information for this interaction is not currently available.

ADJUST DOSING INTERVAL: Coadministration of vadadustat with oral products containing multivalent cations such as calcium, magnesium, or aluminum may significantly decrease the bioavailability of vadadustat. The mechanism of this interaction has not been fully described but may involve the formation of an insoluble complex or chelate with multivalent cations that is poorly absorbed from the gastrointestinal tract. According to product labeling, when non-iron-containing phosphate binders were coadministered-administered with vadadustat, the systemic exposure (AUC) and peak plasma concentration (Cmax) decreased by 55% and 52%, respectively.

MANAGEMENT: Vadadustat should be administered at least one hour before, or two hours after the administration of oral non-iron-containing phosphate binders or other medicinal products whose primary component consists of multivalent cations such as calcium, magnesium, or aluminum.

Major

magnesium hydroxide vadadustat

Applies to: Acid Controller Complete Dual Action (calcium carbonate / famotidine / magnesium hydroxide) and vadadustat

Consumer information for this interaction is not currently available.

Moderate

famotidine vadadustat

Applies to: Acid Controller Complete Dual Action (calcium carbonate / famotidine / magnesium hydroxide) and vadadustat

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with vadadustat, an organic anion transporter 3 (OAT3) inhibitor, may increase the plasma concentrations and the risk of adverse effects of drugs that are substrates of OAT3. A drug interaction study evaluating the effect of repeat doses of vadadustat (600 mg once daily) on the pharmacokinetics of furosemide, an OAT1/OAT3 substrate, showed a 2-fold increase in furosemide systemic exposure (AUC).

MANAGEMENT: Caution is advised if vadadustat is used in combination with organic anion transporter 3 (OAT3) substrates. Monitoring for signs and symptoms of increased exposure to the OAT3 substrate should be considered whenever vadadustat is added to or withdrawn from therapy. The prescribing information for concomitant medications may be consulted to assess the benefits versus risks of coadministration, as well as any dosage adjustments that may be required during coadministration and/or following the discontinuation of an OAT3 inhibitor.

Minor

famotidine calcium carbonate

Applies to: Acid Controller Complete Dual Action (calcium carbonate / famotidine / magnesium hydroxide) and Acid Controller Complete Dual Action (calcium carbonate / famotidine / magnesium hydroxide)

Information for this minor interaction is available on the professional version.

Minor

famotidine magnesium hydroxide

Applies to: Acid Controller Complete Dual Action (calcium carbonate / famotidine / magnesium hydroxide) and Acid Controller Complete Dual Action (calcium carbonate / famotidine / magnesium hydroxide)

Information for this minor interaction is available on the professional version.

Drug and food interactions

Moderate

calcium carbonate food

Applies to: Acid Controller Complete Dual Action (calcium carbonate / famotidine / magnesium hydroxide)

Calcium absorption may be increased by taking it with food. However, foods high in oxalic acid (spinach or rhubarb), or phytic acid (bran and whole grains) may decrease calcium absorption. Calcium may be taken with food to increase absorption. Consider spacing calcium administration for at least 2 hours before or after consuming foods high in oxalic acid or phytic acid. Talk to your doctor if you have any questions or concerns. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate

vadadustat food

Applies to: vadadustat

Consumer information for this interaction is not currently available.

MONITOR: Smoking and alcohol consumption during therapy with vadadustat may increase the risk of gastrointestinal erosions. Serious erosions, including gastrointestinal bleeding and the need for red blood cell transfusions, have been reported during vadadustat clinical trials. Patients with a history of gastrointestinal erosion, peptic ulcer disease, and current tobacco smokers and alcohol drinkers may be at higher risk of gastrointestinal injury.

MANAGEMENT: Caution is advised if vadadustat is prescribed to current tobacco smokers or alcohol drinkers. Patients should be advised to contact their physician if they develop potential signs and symptoms of gastrointestinal injury such as abdominal pain, hematemesis, trouble swallowing, chest or throat pain, and/or black, tarry stools.

Minor

famotidine food

Applies to: Acid Controller Complete Dual Action (calcium carbonate / famotidine / magnesium hydroxide)

Information for this minor interaction is available on the professional version.

Report options

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.
