Q

non HRT treatment

A
  • antidepressants (often not needed when hormones corrected)
  • vaginal moisturiser (Replens)
  • clonidine 50-75mcg BD (antihypertensive, for flushing, if can’t take oestrogens, not 1st line)
  • self-help groups
  • psychotherapy
  • counselling
  • supplements/homeopathy (poor evidence)
22
Q

benefits of HRT

A

treating vasomotor symptoms (hot flushes, night sweats)
treating urogenital symptoms (vaginal dryness)
managing sleep
mood disturbances caused by hot flushes/night sweats
preventing osteoporosis

23
Q

When can you get risks with HRT?

A

risks associated with LT use

24
Why are risks with HRT now lower?
``` not taken orally transdermal preparations used now bypass absorption from GIT can use lower doses straight to blood stream therefore, the risks are much lower ```
25
risks with HRT
``` depends on delivery method combined oral HRT: - small increased risk of breast/ovarian cancer - coronary events - VTE - stroke ```
26
advice for HRTs
minimum effective dose for the shortest duration
27
oestrogen dose in HRT
oestrogen would cause the lining of the uterus to proliferate this increases the risk of uterine cancer therefore, combined with progestogen - progestogen opposes the overproliferation of the uterus can be combined or both taken separetely
28
When is progestogen not needed?
hysterectomy
29
disadvantages with combined products
less flexibility if alteration in oestrogen dose is needed | contain older progestogens
30
considerations with oral oestrogens
- VTE risk with oral oestrogen - oral oestrogen increases SHBG so reducing free androgen, lowers libido - less reliable absorption - more contraindications (obesity, diabetes, gallbladder disease, migraine)
31
What is the optimal HRT regimen?
transdermal oestrogen with micronised progeserone | doesn't increase CV risk
32
problems with transdermal oestrogens/why they might not be used
some women can't absorb it through their skin patches come off can't tolerate adhesive
33
2 options for oral oestrogen formulations
1. oestrogen with continuous progestogen | 2. oestrogen with cyclical progestogen
34
best oestrogen formulation
17 betaestradiol
35
How long should HRT be taken for?
for as long as the benefits outweigh the risks | annual review conducted
36
clot risks with transdermal oestrogen
no clot risks | can be given to women who have Hx/risk of clot/stroke, migraines, hypertension, CVD
37
When should cyclical progesterone be given?
give cyclical HRT for first 6-12 mths to women having periods (peri-menopause)
38
Why is continuous progestogen better?
it's better for endometrial protection
39
Who can take continuous progestogen and s/e?
any age | can cause erratic bleeding if given too early
40
What type of progestogen is given?
micronised progesterone - Utrogestan
41
prescribing of micronised progestogen
cyclically - 200mg every evening for 2 out of 4 weeks continuously - 100mg every evening
42
What is a 3-monthly cyclical regimen?
oestrogen given every day progestogen given for 14 days every 13 weeks (bleed every 3 mths) more suitable for women with infrequent periods/intolernt to progestogens
43
continuous regimen advantage and s/e
preferred because they don't give a wiithdrawal bleed | may have irregular bleeding/spotting for the first 4-6mths
44
Why is the combined form preferred?
because the adverse effects of progestogen can lead to poor compliance if given separately
45
What counselling if giving separate oestrogen and progestogen?
counselling about the protective effect of progestogens to ensure compliance
46
other HRT preparation
IUD Mirena - contains levonorgestrel - LNG delivered locally to the uterus - much lower daily dose needed - delivers progestogen to protect the endometrium - aslo a contraceptive - low bleed risk - safe for up to 5 years - irregular bleeding/spotting
47
vaginal oestrogen
- not HRT - applied to the vagina for vaginal atrophy - systemic absorption of low-dose vaginal oestrogen is very low and doesn't relieve other symptoms (hot flushes) - can be used with HRT or for post-menopausal women who have vaginal symptoms after stopping HRT
48
types of vaginal oestrogen
ortho gynest vagifem pessaries Estring vaginal ring
49
advantages of testosterone for menopause
can improve sexual function/libido general wellbeing improve mood/energy/stamina/concentration/ brain fog/memory
50
disadvantages of testosterone
- no available licenced preparations in UK (off licence) - need to make sure oestrogen levels are well controlled before adding testosterone (no vasomotor symptoms) - can take weeks/months for beneficial effects
51
When should HRT be stopped in an emergency (oral oestrogen)?
- stop 4-6 weeks before surgery - severe chest pain - breathlessness - severe pain the calf of one leg - severe stomach pain - severe neurological effects - hepatitis, jaundice, liver enlargement - BP > 160/100 - prolonged immobility (DVT risk) - detection of a risk factor
52
When to stop HRT?
- symptom control - trial withdrawal after 1-2yrs if symptom free - early menopause - take HRT unitl the age of natural menopause - gradual dose reduction, not abrupt withdrawal - severe symptoms for months after stopping, consider restarting
53
contraception and HRT
HRT doesn't provide contraception U50 considered fertile for 2 yrs after last period O50 considered fertile for 1 yr after last period no risk factors can use low-oestrogen combined contraceptive pill if required/usually POP/barrier/IUD
