Welcome to HealthcareMagic
DHEA tablets are indicated in old ( >35 yrs ) patients or in patients who have low egg store in their ovaries to increase the quality and quantity of their eggs. With such high DHEAs levels I dont think you should continue with DHEA tablets, instead she should be given dexamethasone
tablets to reduce the DHEAs levels to normal. High DHEAs levels may deteriorate the quality of eggs. Please consult your doctor regarding further management.
