Interaction

MR complained about muscles pains, which she attributed to low potassium and her water pill.

After a thorough medication reconciliation, the pharmacist determined that her muscle pains were actually due to an interaction between amlodipine 5 mg and simvastatin 40 mg.

After informing MR's doctor, simvastatin 40 mg was changed to rosuvastatin 5 mg. The successful switch resulted in the absence of subsequent muscle pain.
