Serum concentrations of methotrexate have been shown to be increased with concurrent use with amoxicillin, while mycophenolate concentrations may be decreased. These immunosuppressant drugs are used in patients with serious conditions, and therefore patients who require the use of amoxicillin while on these drugs should be monitored closely.
