Phenoxymethylpenicillin may reduce the excretion of methotrexate causing an increased risk of toxicity. During treatment with phenoxymethylpenicillin non-enzymatic urinary glucose tests may be false-positive.

To reduce the development of drug-resistant bacteria and maintain the effectiveness of penicillin-VK and other antibacterial drugs, penicillin-VK should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy.
