Final answer:
If a drug-drug interaction is expected, the pharmacy software should alert the pharmacist, who must then inform the physician, update the patient's records, and document the interaction.
Step-by-step explanation:
When a drug-drug interaction is expected, several steps must be taken according to the Drug-Drug Interaction and Allergy-Drug Reaction Policy. Pharmacy software should be designed to provide an alert to the pharmacist when such an interaction is detected. The pharmacist should then notify the physician who prescribed the drugs to discuss potential alternative medications or adjustments to the treatment regimen.
In addition, the patient’s medication list and allergies must be reviewed and updated to reflect current information. Actions taken regarding the interaction should be documented in the pharmacist's notes to ensure that appropriate follow-up can occur if needed. The patient themselves should not be asked to contact the doctor; this is the responsibility of the pharmacist who is managing the drug interactions.
