One of the more common side effects of DHEA supplements is acne. Other side effects include insomnia, fatigue, oily skin, abdominal pain, hair loss, nasal congestion, rapid or irregular heartbeats and heart palpitations.

DHEA supplements may alter liver function, so people with liver disease shouldn't use the hormone. People with mood disorders (such as depression) should only use DHEA under the supervision of their healthcare provider, as DHEA supplementation may worsen mood. High levels of the body's natural DHEA has been associated with psychotic disorders, so people with or at risk for psychotic disorders shouldn't use DHEA unless under the supervision of their healthcare provider.

People taking DHEA supplements may be more likely to develop blood clots, so people with clotting disorders, heart disease and those with a history of stroke should avoid DHEA supplements.

DHEA may interact in unpredictable ways with the following drugs:

• Corticosteroids, such as prednisone, beclomethasone (Beconase, Vancenase), dexamethasone, hydrocortisone, prescribed for inflammatory conditions such as arthritis, asthma and skin infections.
• Insulin
• Lithium
• Prescription drugs that are broken down by the same liver enzymes, including: allergy medication (such as fexofenadine), antifungal drugs (such as itraconazole and ketoconazole), cancer medications (such as etoposide, paclitaxel, vinblastine, or vincristine), cholesterol medications (such as lovastatin) and oral contraceptives.
