Sunday's Panorama focused on the potential side effects of Seroxat, one of Britain's most widely used anti-depressants.
Prompted by the large e-mail response created from a previous Panorama about Seroxat, this programme takes an in depth look at the reactions of some people to the drug.
It asks if the drugs regulator, the Medicines and Health products Regulatory Agency (MHRA), is failing to protect patients.
Dr Alistair Benbow of GlaxoSmithKline was in the studio for a discussion about Seroxat, which starts after the programme finished on Sunday, 11 May.
He was joined by Charles Medawar, co-author of the medical report which was based on the e-mails sent in by Panorama viewers.
Also on the panel was Dr Alfred White, from the Royal College of Psychiatrists, who says that Seroxat can be a very useful drug.
