Lo Loestrin Fe vs. Ortho Tri-Cyclen
See how Lo Loestrin Fe and Ortho Tri-Cyclen compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Lo Loestrin Fe has the lowest estrogen dose of any FDA-approved birth control pill, while Ortho Tri-Cyclen uses a standard triphasic estrogen dose used safely since 1989.
Both carry the same boxed warning about smoking-related cardiovascular risks, but only Ortho Tri-Cyclen is FDA-approved to treat moderate acne.
Lo Loestrin Fe's brand-only pricing runs far higher than Ortho Tri-Cyclen, which has multiple low-cost generic versions like Tri-Sprintec and TriNessa.

Lo Loestrin Fe vs. Ortho Tri-Cyclen Indications
Lo Loestrin Fe
Lo Loestrin Fe is FDA-approved to prevent pregnancy in women who choose oral contraceptives. Its ultra-low estrogen dose makes it an option for people who want effective contraception with less overall hormone exposure. Some clinicians also prescribe it off-label to help manage acne or other hormone-related symptoms, though this is not an FDA-approved use.
Pregnancy prevention (FDA-approved)
Off-label acne or hormonal symptom management
Lowest available estrogen dose among oral contraceptives
Not approved for STI or HIV protection
Ortho Tri-Cyclen
Ortho Tri-Cyclen is FDA-approved both to prevent pregnancy and to treat moderate acne vulgaris in females 15 and older who also want contraception. Its triphasic dosing gradually increases progestin across three weeks to mimic the body's natural hormone pattern. Generic versions carry the same two approved uses.
Pregnancy prevention (FDA-approved)
Moderate acne treatment (FDA-approved)
Triphasic dosing mimics natural hormone cycle
Not approved for use within 4 weeks postpartum
Lo Loestrin Fe vs. Ortho Tri-Cyclen Pros and Cons
Lo Loestrin Fe
Lo Loestrin Fe stands out for using the lowest estrogen dose of any approved birth control pill, which may appeal to people sensitive to estrogen-related side effects. It is brand-only, and list prices vary widely depending on pharmacy and insurance coverage. Like all combination pills, it carries a boxed warning about smoking-related cardiovascular risks.
Pros
Lowest estrogen dose of any FDA-approved pill
Only 2 low-dose hormone days instead of a full placebo week
May cause less estrogen-related nausea or breast tenderness for some users
Cons
Brand-only, with no generic version available
Roughly $171 to $1,017 per month without insurance
Not FDA-approved for acne, unlike Ortho Tri-Cyclen
Lower estrogen dose leaves less margin for error with missed pills
Ortho Tri-Cyclen
Ortho Tri-Cyclen offers decades of real-world use and is one of the few pills FDA-approved to treat acne alongside contraception. The brand itself is discontinued, but generics like Tri-Sprintec and TriNessa keep it widely accessible and inexpensive. It uses a standard estrogen dose and a full 7-day placebo week, unlike Lo Loestrin Fe's shorter hormone-free interval.
Pros
FDA-approved to treat moderate acne, not just off-label
Roughly $10 to $55 per month depending on generic or brand
Decades of clinical use and safety data since 1989
Cons
Standard 0.035 mg estrogen dose, higher than Lo Loestrin Fe's
Full 7-day placebo week may allow more hormone fluctuation
Not recommended for breastfeeding due to reduced milk supply
Triphasic dosing means pills must be taken in the correct order
