Oral Contraceptive Pill Brands to Prescribe
For most patients requiring oral contraception, a combined hormonal contraceptive (CHC) containing ethinyl estradiol 20-30 mcg with a third or fourth generation progestin is recommended as first-line therapy, with specific brand selection based on patient characteristics and potential non-contraceptive benefits. 1, 2
Types of Oral Contraceptive Pills
Combined Hormonal Contraceptives (CHCs)
CHCs contain both estrogen and progestin components and are available in various formulations:
Monophasic pills (same hormone dose throughout cycle)
Drospirenone-containing pills (4th generation progestin):
Norgestimate-containing pills (3rd generation progestin):
- Ortho-Cyclen® (norgestimate 0.25mg/ethinyl estradiol 35mcg) 7
Multiphasic pills (varying hormone doses throughout cycle)
- Ortho Tri-Cyclen® (norgestimate 0.18-0.25mg/ethinyl estradiol 35mcg)
Progestin-Only Pills (POPs)
- Norethindrone 0.35mg (Micronor®, Nor-QD®) 8
- Drospirenone 4mg (Slynd®)
Selection Algorithm Based on Patient Characteristics
1. For patients with no specific concerns:
- Start with a low-dose CHC (20-30mcg ethinyl estradiol) with a third or fourth generation progestin
- Examples: Yasminelle® (drospirenone/EE 20mcg) or Ortho-Cyclen® (norgestimate/EE 35mcg)
2. For patients with specific concerns:
Acne or hirsutism:
- Choose CHCs with anti-androgenic progestins:
Premenstrual symptoms/PMDD:
Water retention/bloating concerns:
History of headaches (without aura):
- Lower estrogen dose (20mcg) options like Yaz® or Yasminelle® 9
Heavy menstrual bleeding:
- Higher estrogen dose (30-35mcg) options like Yasmin® or Ortho-Cyclen® 9
Medical contraindications to estrogen:
- Progestin-only pills like norethindrone 0.35mg 8
- Consider non-oral options like IUDs or implants for higher efficacy 2
Important Considerations
Efficacy
- CHCs have a typical failure rate of approximately 5-8% with typical use 1, 8
- POPs have a typical failure rate of approximately 5% with typical use 8
- Perfect use failure rates are much lower (0.1-0.5%) 8
Safety Considerations
- Blood pressure measurement is required before initiating CHCs 1
- Avoid CHCs in women with:
- History of VTE, stroke, or coronary artery disease
- Migraine with aura
- Uncontrolled hypertension
- Age ≥35 years who smoke
- Multiple cardiovascular risk factors 1
Medication Interactions
- Efficacy may be reduced with:
- Certain anticonvulsants (phenytoin, carbamazepine, barbiturates, primidone, topiramate, oxcarbazepine)
- Rifampin or rifabutin
- St. John's wort 1
Starting Regimens
- CHCs can be started anytime in the menstrual cycle if reasonably certain patient is not pregnant
- If started >5 days after menses began, abstain from sex or use barrier methods for 7 days 1
- For norethindrone or norgestrel POPs, use backup for 2 days if started >5 days after menses began
- For drospirenone POPs, use backup for 7 days if started >1 day after menses began 1
Common Pitfalls to Avoid
- Not accounting for drug interactions - Always check for medications that may reduce contraceptive efficacy
- Overlooking medical contraindications - Screen for VTE risk factors, migraines with aura, and cardiovascular disease
- Not providing clear instructions on missed pills and backup methods
- Failing to consider non-contraceptive benefits when selecting a specific formulation
- Not discussing potential side effects like breakthrough bleeding, especially in the first 3-6 months of use
While long-acting reversible contraceptives (LARCs) like IUDs and implants are more effective than OCPs 2, oral contraceptives remain a popular choice for many patients and can be tailored to provide additional non-contraceptive benefits.
