Case One 

Coenzyme Q10 and Statin-Induced Myalgia

LG, a 45-year-old woman, arrives at the pharmacy counter with a prescription for simvastatin 40 mg once daily. She explains that her doctor just prescribed this medication to her to lower her cholesterol. She then inquires about coenzyme Q10, stating, “My friend who also takes simvastatin suggested I take this to prevent muscle pain.” LG takes no other prescription or OTC medications.

How might the pharmacist advise LG? 


Case Two


GL, a 23-year-old man, comes to your pharmacy with a prescription for amoxicillin 500 mg 3 times daily. He explains to the pharmacist that his doctor prescribed the antibiotic to treat a respiratory infection. GL then inquires about probiotics, stating, “My doctor told me I should consider taking this to prevent diarrhea.” 

What advice might you have for GL?
