Does evening primrose oil help with hot flushes?
Current evidence does not support evening primrose oil as an effective treatment for hot flushes, although it is commonly used as a supplement by women in menopause.
Detailed Medical Explanation
Evening primrose oil contains gamma-linolenic acid (GLA), an omega-6 fatty acid, and has been promoted for menopausal symptoms. However, large trials and systematic reviews have not shown consistent benefit for hot flushes. Side effects such as stomach upset and interactions with certain medications can occur. See the NHS menopause treatment page for more information.
Clinical Context
While evening primrose oil is widely available as an over-the-counter supplement, it should not replace evidence-based therapies. Consult with your GP before starting any new supplement.
Evidence-Based Approaches
NICE and NHS guidelines do not recommend evening primrose oil as a primary option for hot flushes. Any use should be informed by current evidence and medical advice. See NICE menopause guidance.
