The U.S. Food and Drug Administration (FDA) cautions health care providers and patients regarding the use of testosterone replacement therapy products for the aging process, including a decrease in muscle strength, muscle mass, and lack of energy or sexual desire, due to an increased risk of heart attacks and strokes. Testosterone replacement therapy products are indicated for genetic defects, chemotherapy damage, or damage to the hypothalamus or pituitary gland, where testosterone is produced. A patient and his team of health care professionals must seriously consider the risks and benefits when using these products for other indications. Use of testosterone replacement therapy products for low testosterone due to natural aging has been on the rise due to disease state awareness, pharmaceutical marketing and media attention. Pharmacists can make a difference in patients' lives by conducting patient education and counseling for these products.
