When it comes to spotting health scams, be skeptical. Question what you see or hear in ads or online. Newspapers, magazines, movies, and radio and TV stations do not always check to make sure the claims in their ads are true or say if a celebrity is being paid to endorse a product. Ask your doctor, nurse, other healthcare provider, or pharmacist about a product before you buy it. Don’t let a salesperson talk you into making a snap decision. Look for red flags in ads or promotional material.
