DHEA Replacement Dosage for Females After Primary Adrenalectomy
For females undergoing primary adrenalectomy, the recommended DHEA replacement dose is 25 mg as a single daily oral dose, which can be adjusted within the range of 10-50 mg based on serum hormone levels and clinical response. 1
Rationale for DHEA Replacement
Women who undergo adrenalectomy experience deficiency in adrenal androgen secretion, particularly dehydroepiandrosterone (DHEA). This deficiency can lead to:
- Decreased libido
- Low energy levels
- Reduced quality of life
- Androgen deficiency symptoms
Dosing Protocol
Initial Dosing
- Start with 25 mg oral DHEA daily, taken in the morning 1
- This dose represents the most common effective starting point for most female patients
Dose Adjustment
- Monitor serum DHEA sulfate (DHEAS), androstenedione, and testosterone levels
- Target: Maintain hormone levels within normal range when measured in the morning prior to DHEA ingestion
- Dose range: 10-50 mg daily, adjusted based on laboratory values and clinical response 1
Monitoring Parameters
- Serum DHEAS levels
- Androstenedione levels
- Testosterone levels
- Clinical symptoms (energy, libido, well-being)
- Side effects
Clinical Approach
Initial Trial Period:
- Offer a 6-month trial of DHEA replacement to female patients with persistent lack of libido and/or low energy levels despite optimized glucocorticoid and mineralocorticoid replacement 1
- Continue therapy if clinically effective
Laboratory Assessment:
- Measure morning hormone levels before daily DHEA dose
- Target normal physiological ranges for age
Efficacy Evaluation:
- Assess improvement in libido
- Evaluate energy levels
- Monitor overall quality of life
Potential Side Effects
- Increased sebum production
- Facial acne
- Changes in hair status
- Androgenic effects at higher doses
Important Considerations
- There is limited objective evidence of clinical benefit from large studies 1
- Long-term effects of DHEA replacement therapy in patients with primary adrenal insufficiency are not fully known
- Use with caution due to limited long-term safety data
- DHEA is not considered standard replacement therapy but may be justified for individual patients with impaired well-being
Pitfalls to Avoid
- Using doses above 50 mg daily may lead to supraphysiological androgen levels in women
- Failure to monitor hormone levels may result in under or over-replacement
- Not accounting for individual variations in DHEA metabolism
- Overlooking the need to adjust doses based on clinical response
The 25 mg daily dose has been shown to restore DHEA(S) to baseline levels in women, while higher doses (100 mg) can lead to supraphysiological concentrations that may increase risk of androgenic side effects.
