How often should medication therapy be reviewed for potential interactions?

Medication therapy should be reviewed for potential interactions whenever a new medication is prescribed. This approach is crucial because the introduction of a new medication can alter the effectiveness and safety of existing medications, potentially leading to harmful interactions. Pharmacists play an essential role in this process, as they are trained to evaluate the entire medication regimen for any new interactions, contraindications, or side effects that may arise from the combination of drugs.

Regular reviews ensure that any changes in the patient's health status, new medications, or changes in therapy are taken into consideration. It helps in optimizing the therapeutic outcomes while minimizing risks associated with drug interactions. This practice is vital for maintaining patient safety and promoting effective medication use, making it an integral part of comprehensive pharmaceutical care.
