Morning-after-pill may be less effective on heavy women

Britain's most popular emergency contraception pill is being reviewed by the UK drugs watchdog following claims it is ineffective on heavier women.

Researchers at Edinburgh University found that Norlevo, made by HRA Pharma, was less effective in women over 11st 3lb (75kg) and ineffective in women over 12st 8lb (80kg).

The US is reviewing guidance as the active ingredient in Norlevo is used in other brands of morning-after pill.

Louise Melvin, from the Faculty of Sexual and Reproductive Health told BBC Radio 5 live's Dominic Laurie: "I would advise women in need of emergency contraception to seek advice from a health professional."
