From the Guidelines

You should consider discussing an adjustment to your estrogen dose with your healthcare provider, as fatigue and anxiety can be significant side effects that impact your quality of life, and there may be alternative dosing strategies that can help mitigate these symptoms. Fatigue and anxiety can be side effects of increased estrogen, and they may improve over time as your body adjusts. However, these symptoms shouldn't be severe or significantly impact your quality of life. According to a recent study on hormonal replacement therapy 1, transdermal administration of 17β-estradiol is preferred due to its better safety profile and more beneficial effects on circulating lipids, markers of inflammation, and blood pressure.

Possible Adjustments

  • Consider trying an intermediate dose between your previous and current levels, for example, if you increased from 1mg to 2mg daily, you might try 1.5mg as a compromise that could reduce side effects while still managing spotting.
  • Alternatively, your provider might suggest splitting your current dose throughout the day to maintain more consistent hormone levels, which could help alleviate fatigue and anxiety.

Monitoring Symptoms

  • Keep a symptom diary to track patterns and severity to help your provider make appropriate adjustments.
  • If you experience severe anxiety, panic attacks, or extreme fatigue, contact your healthcare provider promptly as these could indicate the dose is too high for your body.

Key Considerations

  • Estrogen affects neurotransmitters like serotonin and GABA, which influence mood and energy, explaining these side effects 1.
  • The goal is to find a balance that manages your symptoms, such as spotting, while minimizing side effects like fatigue and anxiety.

From the Research

Expected Symptoms with Increased Estrogen

  • Fatigue and anxiety are not directly mentioned as expected symptoms of increased estrogen in the provided studies 2, 3, 4.
  • However, study 5 suggests that estrogen changes can contribute to vulnerability to major depressive disorder (MDD) in women, which may include symptoms of anxiety and fatigue.
  • Study 6 discusses the treatment of generalized anxiety disorder, but does not specifically address the relationship between estrogen and anxiety.

Dose Titration and Symptom Management

  • Study 4 supports dose titration, as it found a significant difference in response between two different doses of estradiol transdermal system.
  • The study suggests that the onset of efficacy is within 1 to 2 weeks after the start of therapy, and that efficacy is fully sustained during the 7-day patch wear period 4.
  • If symptoms of fatigue and anxiety persist, it may be necessary to explore alternative doses or formulations of estrogen, or to consider non-hormonal treatments for anxiety, such as those discussed in study 6.

Non-Hormonal Treatment Options

  • Study 3 mentions non-hormonal approaches, such as citalopram, desvenlafaxine, escitalopram, gabapentin, paroxetine, and venlafaxine, which are associated with a reduction in frequency of vasomotor symptoms by approximately 40% to 65%.
  • Study 6 discusses the use of these medications as first-line treatments for generalized anxiety disorder.
