Menopause: HRT risks and benefits, alternatives and NICE guidance

RezzyRezzy

Menopause is a huge topic for the AKT, and getting your head around the NICE guidance (NG23) is key to picking the right management for your patients. It's all about balancing that "symptom control vs. long-term risk" equation.

I'll start by pulling up some high-yield lessons on menopause and HRT to give you a solid foundation for your revision.

The NICE guidance (NG23) emphasizes that for most women over 45, menopause is a clinical diagnosis based on symptoms like hot flushes and irregular periods—you don't usually need FSH levels unless they're younger.

When it comes to HRT, the "risk vs. benefit" conversation is what usually comes up in the AKT. I've found a great summary table that breaks down these risks clearly, especially the differences between oral and transdermal options.

It's important to distinguish between the different types of HRT because the risk profile changes significantly depending on whether you're using estrogen alone or a combined preparation.

Here’s a breakdown of the key risks and benefits based on the latest NICE guidance:

FeatureEstrogen-Only HRTCombined HRT (Estrogen + Progestogen)
Breast CancerLittle to no change in riskIncreased risk (related to progestogen and duration)
VTE (Blood Clots)Increased risk with oral; No increased risk with transdermalIncreased risk with oral; No increased risk with transdermal
StrokeSmall increase with oral HRT in women >60Small increase with oral HRT in women >60
CVD (Heart)No increased risk if started <60No increased risk if started <60
Endometrial CancerIncreased risk (must only be used if no uterus)No increased risk (progestogen protects the lining)
OsteoporosisDecreased risk of fracturesDecreased risk of fractures
SymptomsEffective for vasomotor & urogenital symptomsEffective for vasomotor & urogenital symptoms

For women who can't or don't want to take HRT (like those with a history of breast cancer), NICE recommends several alternatives. It's also worth noting that vaginal estrogen can be used long-term for urogenital atrophy, even in many women who can't take systemic HRT, as the absorption is minimal.

Here are the main non-hormonal options:

  • Cognitive Behavioral Therapy (CBT): NICE specifically recommends this for managing low mood and anxiety related to menopause.
  • SSRIs/SNRIs: Drugs like Venlafaxine can help with vasomotor symptoms (hot flushes). Note: Avoid Paroxetine or Fluoxetine if the patient is on Tamoxifen, as they interfere with its metabolism.
  • Gabapentin: Another option for hot flushes, though it can cause drowsiness.
  • Clonidine: An older option for vasomotor symptoms, but often less effective and can cause dry mouth.
  • Lifestyle: Weight loss, regular exercise, and avoiding triggers like caffeine, alcohol, and spicy foods can make a real difference.

If you're feeling ready to test your knowledge on these guidelines, I can set up a quick quiz for you!

I've set up a quiz for you to test your knowledge on these guidelines. It's a great way to lock in those risk/benefit ratios for the AKT!

If you want to dive deeper into any of these, like the specific management of Premature Ovarian Insufficiency (POI) or the different types of progestogens, just let me know!
