A leading US obstetricians and gynaecologists' organisation has updated its guidance on managing menopause symptoms for the first time in 12 years, highlighting hormone therapy and nonhormonal treatments for hot flashes, night sweats and sleep problems.

The American College of Obstetricians and Gynecologists (ACOG) released the recommendations this month, urging women to consult doctors and seek appropriate treatment.

Menopause occurs after 12 consecutive months without menstruation, usually around age 50 in the United States. More than half of menopausal women experience hot flashes and night sweats, while up to two-thirds report sleep disruptions.

Harvard Medical School professor Dr JoAnn Manson said hormone therapy is the first-line treatment for moderate to severe symptoms, although it is not suitable for everyone.

Concerns over breast cancer and blood clots following a 2002 study led to a government warning on hormone treatments for more than 22 years. The FDA announced last year that it would remove the warning from more than 20 products. On Friday, it approved updated labels for three additional estrogen patches.

The FDA said manufacturers had doubled production over the past year and it saw no imminent risk of a nationwide shortage.

For women unable to use hormones, options include fezolinetant, elinzanetant, certain antidepressants, cognitive behavioural therapy, exercise, mindfulness, hypnosis and acupuncture.

Doctors urged women not to believe online misinformation, stressing that effective hormonal and nonhormonal options are available.
