Parents whose teenage son died after taking an acne drug are campaigning at Westminster to get it banned.

Jack Bowlby, 16, from Kingston Lisle, near Wantage, was found dead in his room at Cheltenham College on October 12 last year, after taking the drug Roaccutane.

His inquest found that he had died from compression of a ligature.

His parents, Michael and Amanda, say he was one of a growing number of teenagers who were driven to end their lives because the drug’s side-effects included, they say, depression and psychosis.

On Tuesday, they joined four other sets of parents in a debate at Westminster calling on the Department of Health to examine the evidence more closely.

The debate, attended by Wantage MP Ed Vaizey, was called by North Devon MP Nick Harvey, whose constituent Jonathan Medland believes his son’s death was partly caused by the drug.

Jon Medland, a 22-year-old medical student at Manchester University, hanged himself weeks after being prescribed the drug.
