The generic name for the brand-name oral contraceptive Ortho Tri-Cyclen is norgestimate and ethinyl estradiol. This combined oral contraceptive (COC) contains both a progestin (norgestimate) and an estrogen (ethinyl estradiol). Generic drugs have the same active ingredients as their brand-name counterparts, offering the same benefits and potential side effects, often at a lower cost.
How the Medication Works: Mechanism of Action
Norgestimate and ethinyl estradiol prevents pregnancy and addresses other hormonal conditions by mimicking natural hormones. Key actions include:
- Inhibiting Ovulation: It suppresses hormones that stimulate ovulation, preventing egg release.
- Altering Cervical Mucus: It thickens cervical mucus, hindering sperm movement.
- Changing the Endometrial Lining: It modifies the uterine lining, reducing implantation likelihood.
This combination is also approved for treating moderate acne in females over 15 by reducing free testosterone.
Generic Alternatives for Ortho Tri-Cyclen
Ortho Tri-Cyclen has been discontinued, but its generic equivalent, norgestimate and ethinyl estradiol, is widely available. Generic versions are bioequivalent, having the same active ingredients, strength, and dosage form.

- Tri-Sprintec: Another common triphasic generic.
