Which of the following is not listed among the monophasic COC formulations in the material?

• A. Sprintec 28
• B. Yaz
• C. Junel Fe 1/20
• D. Ortho-Novum 7/7/7

Answer: (D)

Monophasic combined oral contraceptives deliver the same amount of estrogen and progestin with each active pill throughout the cycle, so the hormonal exposure is constant in those pills.

Sprintec 28, Yaz, and Junel Fe 1/20 are all monophasic products—each active tablet has the same hormone doses. Ortho-Novum 7/7/7, on the other hand, is a triphasic formulation, meaning the hormone doses change across the cycle in three phases (7 days each).

So the option not listed as monophasic is the triphasic product, which is why it’s the correct choice for “not listed among the monophasic COC formulations.”
