Aetna — Drug safety is easy to overlook when buying medications over the internet to save money. Drugs sold online can be too old, too strong, and too weak and aren’t necessarily made using safe standards, according to the Food and Drug Administration. Some counterfeit drugs can be very dangerous due to the activities of manufacturers outside of the United States, so it is smart to avoid ordering medications off the internet if possible. One exception would be ordering from a trusted source such as a major retail chain in America.
