When a drip is the wrong tool
IV therapy is a delivery method, not a treatment for disease, and there are situations where booking one delays care you actually need. Skip the home drip and see a doctor — urgently, in some cases — if you have chest pain or breathlessness, confusion or fainting, a fever above 39°C, signs of severe dehydration in a child or an elderly relative, vomiting that has persisted beyond 24 hours, blood in vomit or stool, or severe abdominal pain. These are assessment problems, not hydration problems. Similarly, anyone with kidney disease, heart failure or poorly controlled blood pressure should only receive IV fluids under direct medical supervision, and pregnant women should have their obstetrician's sign-off first.
It is also worth saying what drips do not do, because the marketing will not. They do not cure influenza or any viral illness; they make you feel better while your immune system does the work. They do not 'detox' anything — your liver and kidneys handle that, and no infusion accelerates them. They do not compensate long-term for a poor diet, and vitamin levels beyond what your body can use are simply filtered out into expensive urine. A recovery drip after genuine fluid loss is legitimate symptomatic relief.
