Weight-loss drugs could stop hormone replacement therapy from working and increase the associated risks, guidance has warned. The British Menopause Society has told doctors to closely monitor any women who are on hormone replacement therapy (HRT) for the menopause and are also taking a weight-loss jab.

Common side effects of weight-loss jabs could make taking the contraceptive pill ineffective, experts suggest.

Women also reminded that they should use the most effective contraception to avoid pregnancy while taking 'skinny jabs'.
