              Warnings

              Contraindications

              Known hypersensitivity to any component – vonoprazan, or amoxicillin (or other beta-lactam antibacterials [eg, penicillins, cephalosporins])

              Rilpivirine-containing products, owing to inhibition of gastric pH by vonoprazan

              Cautions

              Serious and occasionally fatal hypersensitivity reactions (eg, anaphylaxis, anaphylactic shock, rash, erythema multiforme, and Henoch-Schonlein purpura) reported with components; discontinue immediately and institute appropriate treatment if hypersensitivity occurs

              Severe cutaneous adverse reactions (SCAR), including SJS and TEN, reported with all components; additionally, DRESS and AGEP have been reported with amoxicillin; discontinue at first signs of SCAR

              Clostridioides difficile–associated diarrhea (CDAD) reported with acid-suppressing therapies and nearly all antibacterial agents; CDAD must be considered in all patients who present with diarrhea following antibacterial use; careful medical history necessary since CDAD reported to occur over 2 months after administration of antibacterial agents; if CDAD confirmed, discontinue, and implement appropriate management

              High percentage of patients with mononucleosis who receive amoxicillin develop an erythematous skin rash; avoid in patients with mononucleosis

              Prescribing this regimen in absence of proven or strongly suspected bacterial infection or prophylactic indication is unlikely to provide benefit and increases risk for drug-resistant bacteria

              Serum chromogranin A (CgA) levels increase secondary to drug-induced decreases in gastric acidity; increased CgA level may cause false positive results in diagnostic investigations for neuroendocrine tumors; assess CgA levels at least 14 days after treatment, and consider repeating test if initial CgA levels are high

              Glucose tests: High urine concentrations of amoxicillin may cause false-positive results when using glucose tests based on the Benedict copper reduction reaction that determines the amount of reducing substances, like glucose, in the urine; use enzymatic glucose oxidase reactions instead while taking amoxicillin

              Drug interaction overview

              • Vonoprazan: CYP3A substrate; weak CYP3A inhibitor; CYP2C19 inhibitor
              • Strong or moderate CYP3A inducers
                • Avoid coadministration
                • Strong or moderate CYP3A inducers may decrease exposure of vonoprazan, which may reduce effectiveness
              • Probenecid
                • Closely monitor
                • Amoxicillin undergoes tubular secretion; probenecid may increase amoxicillin systemic exposure by blocking renal tubular secretion, which may increase risk of adverse reactions
              • Allopurinol
                • Discontinue if skin rash occurs
                • Increase incidence of rashes reported with coadministration of allopurinol and amoxicillin
              • Drugs dependent on gastric pH for absorption
                • Rilpivirine: Contraindicated
                • Atazanavir, nelfinavir: Avoid
                • Other antiretroviral drugs: See prescribing for reliance on gastric pH for absorption
                • Other drugs (eg, iron salts, erlotinib, dasatinib, nilotinib, mycophenolate mofetil, ketoconazole, itraconazole); Check prescribing information for modifying time of dosage or avoidance
                • Vonoprazan reduces intragastric acidity, which may alter absorption of certain drugs
              • Sensitive CYP3A4 substrates
                • See prescribing information for sensitive CYP3A substrates
                • Tacrolimus, cyclosporine: Dosage modification (dose reduction) may be needed; monitor closely
                • Vonoprazan (a weak CYP3A inhibitor) may increase exposure of CYP3A4 substrates, which may increase risk of adverse reactions related to these substrates
              • CYP2C19 substrates
                • Clopidogrel: Carefully monitor the efficacy of clopidogrel, and consider alternative anti-platelet therapy
                • Citaprolam, cilostazol: Carefully monitor for adverse reactions
                • Vonoprazan is a CYP2C19 inhibitor; may reduce plasma concentration of the active metabolite of clopidogrel, resulting in reduced platelet inhibition; may increase exposure of CYP2C19 substrate drugs
              • Oral anticoagulants
                • Monitor INR, and adjust dose accordingly
                • Abnormal prolongation of prothrombin time (increased INR) reported in patients receiving amoxicillin and oral anticoagulants

              • Potassium-competitive acid blocker (PCAB)
              • Suppresses basal and stimulated gastric acid secretion at secretory surface of gastric parietal cell through inhibition of the H+,K+-ATPase enzyme system in a potassium-competitive manner
              • Because this enzyme is regarded as the acid (proton) pump within the parietal cell, vonoprazan has been characterized as a type of gastric proton-pump inhibitor, as it blocks the final step of acid production
              • Does not require activation by acid; may selectively concentrate in parietal cells in both resting and stimulated states
              • Binds to active proton pumps in noncovalent and reversible manner

              Amoxicillin

              • Ampicillin derivative; elicits antibacterial effect by binding to penicillin-binding proteins and inhibiting biosynthesis of cell wall
