Menopause Flashcards
Menopause definition
permanent cessation of menses following the loss of ovarian follicular activity; occurs 1 year after last menses, FSH ≥40 IU
Perimenopause definition
immediately prior to menopause and 1st year after menopause begins , characterized by anovulatory bleeding
Postmenopausal definition
period greater than 1 year after menopause occurs
Non-hormonal factors that can contribute to menopause
Age, surgery (bilateral oophorectomy/hysterectomy), chemotherapy, pelvic radiation, smoking
Two categories of menopause symptoms
Vasomotor symptoms (VMS) and Genitourinary syndrome of menopause (GSM)
VMS Sx
Hot flashes, night sweats, occur 12-24 months after last menstrual period
GSM Sx: Genital
dryness, burning, irritation
GSM Sx: Urinary
dysuria, urgency, recurrent UTI Sx
GSM Sx: Sexual
dryness, dyspareunia
Other symptoms associated with menopause
Menstrual irregularity, sleep disturbances, mood changes, difficulty with memory and concentration, osteoporosis
Types of estrogens for HT
Conjugated equine estrogen (CEE), 17-beta estradiol, bioidentical hormones
Where does CEE come from?
Pregnant mare’s urine, natural product
17-beta estradiol
Synthetic product
Bioidentical hormone information
Compounded preparations which are said to provide a unique mix of estradiol, estrone, and estriol at dosages specifically designed for each woman but aren’t FDA regulated
Systemic estrogen routes of administration
PO, TD patch, TD emulsion, TD spray, TD gel, vaginal ring, implanted pellet
Vaginal/local estrogen routes of administration
Vaginal cream, vaginal tablet, vaginal ring
Common ADEs of estrogen
N/V, headache, breast tenderness, heavy bleeding
Serious ADEs of estrogen
CHD, stroke, VTE, breast cancer, gallbladder disease
Role of progestogen in combination HT
Mitigation of endometrial hyperplasia
Who do you give progestogen to?
Women with an intact uterus (aka no hysterectomy)
Progestogen dosing
Given a minimum of 12-14 days/month
Progestogen ADEs
irritability, depression, headache
Types of progestogen products
MPA, norethindrone, micronized progesterone
Preparations of progestogen
Systemic/oral
For cyclic use, how often must the progestogen be taken?
Minimum of 12-14 days per month
For a woman with a Hx of hysterectomy, is use of progestogens indicated?
No
For women with endometriosis with a Hx of hysterectomy, would you use progestogen?
Yes, if combined with estrogen it may minimize endometriosis exacerbations
Continuous cyclic treatment regimen
Estrogen daily, progestogen given the last 12-14 days of every cycle to give scheduled withdrawal bleeding 1-2 days after the last progestogen dose
Continuous combined treatment regimen
Estrogen and progestogen daily, associated with absence of vaginal bleeding
Who is the continuous combined treatment regimen reserved for?
Women 2 years post menopause
Continuous long-cycle treatment regimen
Estrogen daily, with progestogen given 12-14 days EVERY OTHER MONTH, bleeding periods may be heavier and longer than withdrawal bleeding
Intermittent combined treatment regimen
3 days of estrogen alone, followed by 3 days of combined estrogen and progestogen repeated without interruption

WHI results for the group who received estrogen and progesterone vs. placebo
Increased risk of MI, stroke, breast cancer, blood clots
Decreased risk of colorectal cancer and fractures
WHI results for the group who received estrogen only vs. placebo
No difference in risk of MI or breast cancer
Increased risk of stroke and blood clots
Decreased risk of hip fractures
WHI benefits of HT
Relieved Sx of VMS and GSM, decreased hip fracture and osteoporosis and colon cancer
What did the WHI do for HT?
FDA safety warning labels were added to all estrogen and progestogen products for increased risk of MI, stroke, breast cancer, endometrial cancer, thromboembolism
Use the lowest effective dose possible!
Indications for HT therapy
Moderate-severe VMS +/- GSM Sx, moderate-severe GSM Sx alone for vaginal therapies
What should all patients be reviewed for before starting HT?
Contraindications and they should all be offered a discussion on the risks and benefits of HT so they can make an informed decision
HT for VMS length of therapy
<5 years, goal should be cessation within 5 years
HT for GSM
Vaginal products only
Low dose vaginal estrogen usually doesn’t require progestin but long-term use may require intermittent progestin
Length of therapy for GSM HT therapy
Usually require prolonged therapy
Contraception during menopause
All good to use as long as age ≥40 years old
Nonpharm Tx for VMS
Cognitive behavioral therapy, hypnosis, mindfulness-based stress reduction, weight loss (limited evidence of benefit)
Cooling techniques, avoidance of triggers, yoga (insufficient evidence)
Nonpharm Tx for GSM
Nonhormonal vaginal lubricants and moisturizers (1st line for GSM only!)
Herbals for menopause
Black cohosh and phytoestrogens
No evidence for herbals
Androgens for menopause
Methyltestosterone and esterfied estrogens, testosterone; administer with or without concurrent estrogen therapy
ADEs of androgens
Acne, hirsutism, lowering of voice, lipid and liver function changes
SERMs for menopause
Raloxifene (Evista), ospemifene (Osphena), CEE and bazedoxifene (Duavee)
Raloxifene indications
Prevention and treatment of osteoporosis
Ospemifene indication
Severe dyspareunia
CEE and bazedoxifene indications
moderate-severe Sx of VMS in women WITH A UTERUS, prevention of osteoporosis
Raloxifene dosing
60mg PO QD
Ospemifene dosing
60mg PO QD
Duavee dosing
0.45mg CEE, 20mg bazedoxifene
Duavee has an increased risk for…
VTE and CVA
Duavee ADEs
leg cramps, hot flushes, sweating, GI Sx
SSRI for menopause
Paroxetine mesylate (Brisdelle), used for VMS
Paroxetine mesylate dosing
7.5mg PO QD
Paroxetine mesylate ADE
GI Sx
Paroxetine mesylate BBW
Suicidality
Who do you consider paroxetine mesylate in?
Patients with concomitant depression, CIs to HT, or those who don’t wish to take HT
SNRIs for menopause
Desvenlafaxine, venlafaxine (off-label); effective for VMS
Prasterone (Intrarosa) indication
Dyspareunia due to menopause
Prasterone dosing
6.5mg intravaginally QHS daily
Clonidine and gabapentin
Off-label uses for VMS
Patient counseling for HT
Systemic HT is highly effective in alleviating VMS +/- GSM
Using the lowest effective dose and limiting therapy to <5 years removes nearly all risk
HT is indicated for healthy women with significant VMS <60 years old and within 10 years of menopause onset
Discontinuation of HT
Tapered to limit recurrence of hot flashes, slowly D/C over 3-6 months after 4-5 years of therapy
What should women experiencing menopause prior to age 45 do regarding HT?
Use HT until the natural age of menopause (~51 years old in the US)
