Task: Answer Verification
Input (English): Question: Is the bioequivalence of the contraceptive steroids ethinylestradiol and drospirenone affected by co-administration of dehydroepiandrosterone?
Answer: Adding DHEA to a COC containing EE and DRSP does not affect the pharmacokinetic properties of EE and DRSP. Therefore, it will most likely not affect its contraceptive efficacy.
Output (English): no
