After taking the time to visit the doctor and waiting an hour at a pharmacy, no one wants to hear that their medication isn't in stock. Online service Capsule wants to resolve the pain points associated with conventional chemists, delivering prescription drugs straight to New Yorkers’ doors.

Going to the GP can be a pain. Opening hours are short, and prescriptions can be under-explained. These issues are driving a boom in retail healthcare in the US, which is continuing to proliferate as services expand to appease a growing number of people who want more control over their health.

Most healthcare clinics operate during office hours and require long waits, making it difficult for working people to visit unless something serious happens. Subsequently, minor health problems often go ignored or undertreated. Now, time-poor commuters no longer have to ignore health concerns.

The number of people Googling symptoms and diagnosing themselves has reached worrying proportions, with 20% of Brits now turning to the web rather than visiting a GP. Be Your Own Doctor is a new programme from Channel 4 that wants to help viewers navigate this potentially confusing world.
