Case 1:
A 50-year-old man comes to your office for follow-up. Physical examination reveals a body mass index (BMI) of 36
kg/m2, reflecting a gain of 15 lb since he was seen 1 year ago. His fasting blood glucose is 115 mg/dL, up from 95
mg/dL at the last visit. He has a history of cholestasis, caused by gallstones, and glaucoma. He is currently using a
prostaglandin analog for his glaucoma.

Case 2:
A 34-year-old female patient presents for follow-up. Her current BMI is 37 kg/m2. She is frustrated with her futile attempts to lose weight with lifestyle modification. She is interested in the newer medications available to assist with weight loss.
She has a history of hypertension and depression. You discuss the pharmacotherapy options available and give her an overview of their risks and benefits. Due to her busy schedule and many other medications, she decides that the once-a-day
option of phentermine/topiramate extended release (ER) would best suit her lifestyle.
Before you consider starting her on phentermine/topiramate ER, what is an important factor in her medical history to ask about?

C Monoamine oxidase inhibitor (MAOI) use 52% (255) 66% (56) 42% (33)
Your patient returns in 3 months but has only lost 1% of her baseline weight on 7.5 mg/46 mg phentermine/topiramate ER once daily. She reports she has started walking at least a half hour nearly every day but is having trouble adhering to a low-calorie diet. You encourage her to keep records of everything she consumes with calories, for at least a week. What is the next best step regarding her medication?
