Lucy’s stumbled on a connection between her gambling problem and her medication. But her mental health team says they don’t know what she’s talking about.

Freddie’s reached breaking point. And, one day, he notices his dad’s medication leaflet on the kitchen table, sparking a full-blown crisis.

It’s been known for more than two decades that drugs affecting dopamine levels in the brain have potential side effects including impulse control disorders like hypersexuality, or compulsive shopping or gambling.

Warnings have been added to patient information leaflets - but many of the people who’ve contacted BBC investigations correspondent Noel Titheradge about their experiences say the risks weren’t made clear.

Why weren’t they warned about the potential side effects of these medications before it was too late?

Details of organisations offering help and support with some of the issues raised are available at bbc.co.uk/actionline.

If you have any concerns about medication you’re taking, speak to your doctor.
