Genetic differences can affect how our bodies respond to medications. Some people’s genes can make a drug work better or worse, change how safe it is, or influence how much of the drug they need. These genetic changes can affect how the body processes medicine, like how quickly it is broken down or how it interacts with cells. For example, a genetic difference might cause a person’s body to break down a drug too fast, making it less effective, or too slowly, increasing the risk of side effects. This is why people can have different reactions to the same medication.
