From the Guidelines
The primary treatment for Depakote (valproic acid) induced alopecia is discontinuation of the medication or dose reduction, if possible, in consultation with your neurologist or psychiatrist. Hair loss typically begins 3-6 months after starting Depakote and is usually diffuse and non-scarring. If Depakote must be continued, several supportive treatments may help.
- Oral supplementation with zinc (25-50mg daily), selenium (200mcg daily), and biotin (2.5-5mg daily) can support hair growth, as serum levels of these micronutrients tend to be lower in patients with alopecia areata 1.
- Topical minoxidil 2% or 5% solution applied twice daily to the scalp may stimulate hair regrowth.
- Some patients benefit from using gentle, non-medicated shampoos and avoiding harsh hair treatments. The mechanism of Depakote-induced hair loss involves interference with cell division in hair follicles and depletion of certain minerals and vitamins.
- Intralesional corticosteroids, such as triamcinolone acetonide, may also be effective in treating patchy hair loss of limited extent, with 62% of patients achieving full regrowth with monthly injections 1. Hair typically regrows within 3-6 months after discontinuation or dose adjustment of Depakote. Regular monitoring of serum valproate levels may help maintain the lowest effective dose to minimize side effects while controlling the primary condition being treated.
- Counselling and psychological support may also be necessary, especially for patients who are profoundly upset by their alopecia, as it can have a significant impact on their quality of life 1.
From the Research
Treatment Options for Depakote-Induced Alopecia
- Depakote (valproate) induced alopecia is a dose-dependent and reversible side effect, as reported in a case series study 2.
- Treatment involves reassurance, advice on hair care, and if possible, drug discontinuation or dose reduction 3.
- Medications such as biotin and other vitamins with minerals supplementation are effective for most individuals with hair loss 3.
- Other treatment options include agomelatine, topical valproate, or minoxidil, although these lack evidence 3.
- Minoxidil, a topical treatment, has been shown to be effective in promoting hair growth and is FDA-approved for androgenetic alopecia (AGA) in men and women 4.
- The role of vitamins and minerals, such as vitamin A, vitamin B, vitamin C, vitamin D, vitamin E, iron, selenium, and zinc, in non-scarring alopecia is still being researched, and deficiency of these micronutrients may represent a modifiable risk factor associated with the development, prevention, and treatment of alopecia 5.
Management Strategies
- Diagnosis of valproate-associated hair abnormalities is based on history of hair loss or abnormalities following valproate treatment, and is confirmed by use of simple clinical tests such as pull test and modified wash test 3.
- Management includes general measures, such as reassurance and advice on hair care, and specific treatment options, such as medications and supplements 3.
- Recognizing and distinguishing alopecia conditions is crucial in providing adequate and timely treatment to improve outcomes and meet patient needs 6.
