When a drip is the wrong tool
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.
The regulators agree with this framing. DHA and DoH treat these services as medical procedures precisely because the risks are medical, and the professional standard across the UAE is screening first, physician oversight always, and refusal when the picture does not fit. Any provider operating to that standard will occasionally turn down your money. That is the system working.
