BANNED slimming pills were sold by a doctor from a Runcorn clinic, a hearing of the General Medical Council (GMC) heard.
Dr Sudesh Madan, 52, and her husband Dr Surendra Raizada, 56, both of Rainhill, face allegations which could see them struck off.
A disciplinary committee of the GMC was told Dr Madan, aided by her husband, ran the Look Right slimming clinics from hotels in the region.
But it was alleged their real aim was to sell tablets of Duromine, a powerful appetite suppressant.
The pills were taken off the market last year because of suspected links to fits and heart problems. Nine patients were prescribed them.
Duromine can be prescribed for clinically obese patients whose body mass (BMI) is at a certain level.
However, the hearing was told eight of the nine people given the pills were under this threshold.
Dr Madan admits supplying Duromine to five patients who weren't obese, knowing it wasn't recommended, while Dr Raizada admits selling the tablets from his car and to a woman who was not obese.
The couple, of Briars Close, deny acting acted irresponsibly and deny serious medical misconduct.
The hearing continues.
