Interactions between Amoxicillin and Moderna COVID-19 Vaccine

The SARS-CoV-2 (COVID-19) mRNA-LNP vaccine (cvx 334) in Moderna COVID-19 Vaccine has a moderate potential interaction with Coagulation Defects and Disorders.

In patients with thrombocytopenia or coagulation disorders, IM injections may produce bleeding and hematomas. Patients with a platelet count less than 50,000/mm3 are at an increased risk. Caution is advised if the vaccine (e.g., plague vaccine; hepatitis A and B vaccines; aluminum-adsorbed DTaP, DTP, DT, or Td) must be administered IM. The risk of bleeding may be minimized by vaccination immediately after the administration of replacement factor, use of a 23-gauge (or smaller) needle, and immediate application of direct pressure to the vaccination site for at least 2 minutes.

Amoxicillin has a moderate potential interaction with Diabetes Mellitus.

High urine concentrations of ampicillin may result in false-positive reactions when testing for the presence of glucose in urine using Clinitest®, Benedict's Solution or Fehling's Solution. Since this effect may also occur with amoxicillin, it is recommended that glucose tests based on enzymatic glucose oxidase reactions (such as Clinistix®) be used.

Amoxicillin has a moderate potential interaction with Hemodialysis.

Penicillin antibiotics (except for agents in the penicillinase-resistant class) are removed by hemodialysis. Doses should either be scheduled for administration after dialysis or supplemental doses be given after dialysis.

The SARS-CoV-2 (COVID-19) mRNA-LNP vaccine (cvx 334) in Moderna COVID-19 Vaccine has a moderate potential interaction with Immunodeficiency.

Immunocompromised individuals, including those receiving immunosuppressive therapy, may have a diminished immune response to the messenger RNA COVID-19 vaccine. The US CDC has published considerations related to COVID-19 vaccination for individuals who are moderately to severely immunocompromised (https://www.cdc.gov/covid/hcp/vaccine-considerations/).

Amoxicillin has a moderate potential interaction with Mononucleosis.

Patients with mononucleosis treated with an aminopenicillin antibiotic, may develop a pruritic erythematous maculopapular skin rash. The rash is usually self-limiting and resolves within days of discontinuing the offending agent. An altered drug metabolism or an immune-mediated process unrelated to drug hypersensitivity has been proposed as the underlying mechanism. Therapy with aminopenicillin antibiotics should not be administered in patients with mononucleosis.

Amoxicillin has a major potential interaction with Noninfectious Colitis.

Clostridioides difficile-associated diarrhea (CDAD), formerly pseudomembranous colitis, has been reported with almost all antibacterial drugs and may range from mild diarrhea to fatal colitis. The most common culprits include clindamycin and lincomycin. Antibacterial therapy alters the normal flora of the colon, leading to overgrowth of C difficile, whose toxins A and B contribute to CDAD development. Morbidity and mortality are increased with hypertoxin-producing strains of C difficile; these infections can be resistant to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea after antibacterial use. Since CDAD has been reported to occur more than 2 months after antibacterial use, careful medical history is necessary. Therapy with broad-spectrum antibacterials and other agents with significant antibacterial activity should be administered cautiously in patients with history of gastrointestinal disease, particularly colitis; pseudomembranous colitis (generally characterized by severe, persistent diarrhea and severe abdominal cramps, and sometimes associated with the passage of blood and mucus), if it occurs, may be more severe in these patients and may be associated with flares in underlying disease activity. Antibacterial drugs not directed against C difficile may need to be stopped if CDAD is suspected or confirmed. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C difficile, and surgical evaluation should be started as clinically indicated.

Amoxicillin has a moderate potential interaction with Phenylketonuria.

Some amoxicillin chewable tablets and suspensions products contain phenylalanine. The phenylalanine content should be considered when these products are used in patients who must restrict their intake of phenylalanine (i.e. phenylketonurics).

Amoxicillin has a moderate potential interaction with Renal Dysfunction.

Most beta-lactam antibiotics are eliminated by the kidney as unchanged drug and, in some cases, also as metabolites. The serum concentrations of beta-lactam antibiotics and their metabolites may be increased and the half-lives prolonged in patients with impaired renal function. Dosage adjustments may be necessary and modifications should be based on the degree of renal impairment as well as severity of infection in accordance with the individual product package labeling. Renal function tests should be performed periodically during prolonged and/or high-dose therapy, since nephrotoxicity and alterations in renal function have occasionally been associated with the use of these drugs.

The SARS-CoV-2 (COVID-19) mRNA-LNP vaccine (cvx 334) in Moderna COVID-19 Vaccine has a moderate potential interaction with Syncope.

Syncope may occur in association with administration of injectable vaccines, including the messenger RNA COVID-19 vaccine. Procedures should be in place to avoid injury from fainting, especially for patients who have previously fainted in association with an injection.

The SARS-CoV-2 (COVID-19) mRNA-LNP vaccine (cvx 334) in Moderna COVID-19 Vaccine has a moderate potential interaction with Thrombocytopathy.

In patients with thrombocytopenia or coagulation disorders, IM injections may produce bleeding and hematomas. Patients with a platelet count less than 50,000/mm3 are at an increased risk. Caution is advised if the vaccine (e.g., plague vaccine; hepatitis A and B vaccines; aluminum-adsorbed DTaP, DTP, DT, or Td) must be administered IM. The risk of bleeding may be minimized by vaccination immediately after the administration of replacement factor, use of a 23-gauge (or smaller) needle, and immediate application of direct pressure to the vaccination site for at least 2 minutes.
