Prescription medications have transformed modern healthcare by helping treat illnesses, manage chronic diseases, relieve pain, improve mental health, and enhance quality of life for millions of people. From medications that control blood pressure to treatments for anxiety, ADHD, insomnia, allergies, and chronic pain, today’s therapies play an important role in helping people live healthier lives.
However, every prescription medication has both potential benefits and risks.
