Too Much Supplementation May Raise Cancer Risk Taking more nutritional supplements than needed may increase a patient’s risk of cancer.

An example of the pharmacist's role in solving a drug related problem:

An 87 year old lady, has been taking digoxin 0.25 mg daily for her atrial fibrillation for 3 years. Recently you have noticed that she is getting increasingly frail and may have lost weight. On a Saturday morning she presents a new prescription for digoxin. While you prepare the prescription, she tells you that she has been having visual disturbance and wonders if she needs her glasses replaced.

What would you do and why?
