When a medication doesn’t work—even when taken exactly as prescribed—you’re likely facing a therapy gap, a breakdown in treatment effectiveness due to overlooked factors like drug interactions, improper dosing, or individual biological differences. Also known as treatment failure, it’s not always about the drug being weak—it’s often about how it’s used, who’s using it, or what else is in their system. This isn’t rare. Many people take multiple drugs, supplements, or even natural products without realizing how they clash. A simple combo like goldenseal and metformin can lower metformin’s effect, or MAO inhibitors mixed with common painkillers can trigger a life-threatening surge in blood pressure. These aren’t edge cases—they’re everyday mistakes.
Therapy gaps show up in surprising places. Obesity and medication dosing, how body composition changes how drugs are absorbed and processed means standard doses often fail for overweight patients. Therapeutic equivalence, the idea that generics work just like brand-name drugs sounds simple—but psychology, not chemistry, sometimes makes people feel worse after switching. And drug interactions, when two or more substances interfere with each other’s effects are behind half of all preventable hospital admissions in older adults. It’s not just about pills. Cannabis, St. John’s wort, or even expired antibiotics can quietly sabotage treatment. Even something as basic as sleep or circadian rhythm can throw off metabolism and drug effectiveness, turning a good plan into a failed one.
Fixing therapy gaps starts with asking the right questions. Is your dose right for your body? Are you mixing something dangerous with your meds? Is your generic really working the same way? The posts below dive into real cases where treatments fell apart—and how people got them back on track. From opioid-induced low testosterone to why seniors need different blood sugar targets, these aren’t theory pieces. They’re practical guides built from real risks, real data, and real mistakes people made before learning the hard way. You’ll find what to watch for, who’s most at risk, and how to speak up before something goes wrong.
