Medicines for White-coat hypertension
Blood pressure that reads high in a clinical setting but is normal at home — common, and important to recognise so people are not treated unnecessarily.

Quick answer
What is White-coat hypertension?
White-coat hypertension is when a person's blood pressure is raised when measured in a clinical setting (such as a GP surgery or hospital), but is normal when measured away from that setting, for example at home or with a 24-hour monitor. The name comes from the "white coats" traditionally worn by doctors, reflecting that the raised reading is thought to be linked to the anxiety or stress response some people have during a medical appointment.
- How it is treated: The key to recognising white-coat hypertension is measuring blood pressure away from the clinical setting — using either ambulatory blood pressure monitoring (a device worn for 24 hours that takes readings during normal activities) or home blood pressure monitoring (readings taken at home over several days).
- Self-care: Healthy-lifestyle measures that support blood pressure and heart health — a balanced, lower-salt diet, regular physical activity, maintaining a healthy weight, limiting alcohol, not smoking, and managing stress — are advised, along with periodic out-of-clinic blood pressure monitoring.
- When to seek help: If clinic blood pressure readings are high, ask a GP about confirming with home or 24-hour (ambulatory) monitoring, which can identify white-coat hypertension and avoid unnecessary treatment.
What it is
White-coat hypertension is when a person's blood pressure is raised when measured in a clinical setting (such as a GP surgery or hospital), but is normal when measured away from that setting, for example at home or with a 24-hour monitor. The name comes from the "white coats" traditionally worn by doctors, reflecting that the raised reading is thought to be linked to the anxiety or stress response some people have during a medical appointment. It is common. Its importance is twofold: first, recognising it prevents people being wrongly diagnosed with high blood pressure and treated unnecessarily based on clinic readings alone; and second, although the clinic-only rise is not the same as sustained high blood pressure, people with white-coat hypertension do have a somewhat higher long-term risk of developing true high blood pressure and of cardiovascular problems than those whose blood pressure is normal everywhere, so they benefit from monitoring and healthy-lifestyle measures. This is why modern practice confirms a diagnosis of high blood pressure with out-of-clinic readings rather than clinic readings alone.
How it is treated
The key to recognising white-coat hypertension is measuring blood pressure away from the clinical setting — using either ambulatory blood pressure monitoring (a device worn for 24 hours that takes readings during normal activities) or home blood pressure monitoring (readings taken at home over several days). This is now standard practice when clinic readings are raised, precisely to distinguish true sustained high blood pressure (which needs treatment) from white-coat hypertension (which usually does not need blood-pressure medicines). Where white-coat hypertension is confirmed, the person is usually not started on blood-pressure medication, but is advised on healthy-lifestyle measures (which lower cardiovascular risk generally) and is monitored over time — with periodic out-of-clinic blood pressure checks — because of the higher chance of developing true high blood pressure later. Any other cardiovascular risk factors are also managed. The reassuring message is that white-coat hypertension is common and recognising it prevents unnecessary treatment, while sensible monitoring and healthy habits address the modestly increased long-term risk.

Beyond medication
Lifestyle and self-care
Healthy-lifestyle measures that support blood pressure and heart health — a balanced, lower-salt diet, regular physical activity, maintaining a healthy weight, limiting alcohol, not smoking, and managing stress — are advised, along with periodic out-of-clinic blood pressure monitoring.
When to get help
When to see a doctor
If clinic blood pressure readings are high, ask a GP about confirming with home or 24-hour (ambulatory) monitoring, which can identify white-coat hypertension and avoid unnecessary treatment. Attend recommended monitoring, as there is a higher chance of developing true high blood pressure over time.

Answers
White-coat hypertension: frequently asked questions
What is white-coat hypertension?
It is blood pressure that reads high in a clinical setting (such as a GP surgery) but is normal away from it, thought to relate to the stress of the appointment. It is common, and recognising it prevents unnecessary treatment based on clinic readings alone.
Does white-coat hypertension need treatment?
Usually not with blood-pressure medicines, as the blood pressure is normal outside the clinic. However, because there is a higher chance of developing true high blood pressure over time, healthy-lifestyle measures and periodic out-of-clinic monitoring are advised.
