From the Guidelines
Hot flashes during menopause can be effectively managed with non-hormonal medications, such as gabapentin, as the first line of treatment, due to its efficacy and safety profile, as evidenced by studies 1.
Treatment Options
- Non-hormonal medications:
- Gabapentin (300-900mg daily) has been shown to be effective in reducing hot flashes, with a rapid onset of action and minimal side effects 1.
- SNRIs, such as venlafaxine (37.5-75mg daily), and SSRIs, such as paroxetine (7.5-25mg daily), can also reduce hot flash frequency and severity, although they may have more side effects and interactions 1.
- Lifestyle modifications:
Considerations
- Hormone replacement therapy (HRT) is generally not recommended for breast cancer survivors due to the potential increased risk of breast cancer recurrence, although it may be considered in certain cases under the guidance of a specialist 1.
- Local hormonal treatments, such as vaginal estrogen preparations, may be used to treat vaginal dryness, but their safety in survivors of hormone-dependent cancers is still a topic of debate 1.
Recommendation
Gabapentin is a suitable first-line treatment option for hot flashes during menopause, due to its efficacy, safety, and minimal side effects, as supported by the most recent and highest quality studies 1.
From the FDA Drug Label
For treatment of moderate to severe vasomotor symptoms, vulval and vaginal atrophy associated with the menopause, the lowest dose and regimen that will control symptoms should be chosen and medication should be discontinued as promptly as possible. The usual initial dosage range is 1 to 2 mg daily of estradiol adjusted as necessary to control presenting symptoms. Estradiol tablets are indicated in the: Treatment of moderate to severe vasomotor symptoms associated with the menopause.
Menopause Hot Flash Treatment:
- The recommended treatment is estradiol (PO) with a dosage range of 1 to 2 mg daily, adjusted as necessary to control symptoms.
- The goal is to use the lowest effective dose and for the shortest duration consistent with treatment goals and risks for the individual woman 2, 2.
- Estrogens with or without progestins should be prescribed at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman 2.
From the Research
Treatment Options for Menopause Hot Flashes
- Hormone therapy is considered the most effective treatment for menopausal hot flashes, with a success rate of 80-90% 3, 4
- Non-hormonal pharmacologic treatments, such as selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), have been shown to reduce hot flashes by 50-60% 5, 6
- Specific SSRI/SNRI agents, including venlafaxine, paroxetine, fluoxetine, and gabapentin, have been recommended for women with moderate to severe hot flashes who are unable or unwilling to use estrogen therapy 5, 3
Alternative Treatment Approaches
- Behavioral changes and vitamin E supplementation may be a reasonable initial approach for women with mild hot flash symptoms 3
- Progestational agents, such as megesterol acetate, may be a safe alternative for women with a history of breast or uterine cancer 3
- Lifestyle modifications, including dietary changes and stress management, may also be beneficial in reducing hot flash symptoms 7
Efficacy and Safety of SSRI/SNRI Agents
- A systematic review of clinical trials found that escitalopram, paroxetine, and fluoxetine have higher efficacy and safety in the treatment of menopausal hot flashes compared to other SSRI agents 6
- Venlafaxine and desvenlafaxine have also shown significant efficacy in reducing hot flash symptoms, while duloxetine requires further research to confirm its effectiveness 6
