Preventive medications are drugs taken to reduce the risk of developing certain diseases or health conditions. They are often prescribed to individuals who may be at higher risk due to factors like family history, age, or lifestyle. Common examples include statins for heart disease and aspirin to prevent blood clots. These medications work by addressing underlying risk factors before they lead to serious health issues. For instance, vaccines are a form of preventive medication that help protect against infectious diseases. By using preventive medications, individuals can maintain better health and potentially avoid more severe medical problems in the future.
