From the Guidelines
For a patient experiencing daily bleeding for three months since starting combined hormonal contraception, I recommend shortening or eliminating the hormone-free interval by using extended or continuous cycling. This approach can help reduce hormone fluctuations that trigger bleeding, as suggested by studies on continuous combined hormonal contraceptives 1. The current evidence indicates that bleeding irregularities are generally not harmful and usually improve with persistent use of the hormonal method, but modifications to the regimen can help alleviate symptoms sooner 1. Some studies have shown that introducing a hormone-free interval of 3 or 4 days can improve bleeding patterns in women using extended or continuous combined hormonal contraceptives 1. However, before making any changes to the contraceptive regimen, it's crucial to rule out other causes of abnormal bleeding, such as pregnancy, infection, missed pills, or anatomical issues, as recommended in the U.S. Selected Practice Recommendations for Contraceptive Use, 2013 1. Key considerations for managing bleeding include:
- Evaluating for underlying gynecological problems
- Considering NSAIDs or hormonal treatment for short-term management of heavy or prolonged bleeding
- Counseling on alternative contraceptive methods if bleeding persists and is unacceptable to the patient 1. Given the potential for bleeding to impact quality of life, prioritizing a regimen that minimizes hormone fluctuations and provides consistent hormonal levels is essential. This can involve switching to a different formulation of combined hormonal contraception or adjusting the dosing schedule to extend the period of active hormone use, which may help stabilize the endometrium and reduce breakthrough bleeding 1.
From the FDA Drug Label
Breakthrough bleeding, spotting, and amenorrhea are frequent reasons for patients discontinuing oral contraceptives. In breakthrough bleeding, as in all cases of irregular bleeding from the vagina, non-functional causes should be borne in mind In undiagnosed persistent or recurrent abnormal bleeding from the vagina, adequate diagnostic measures are indicated to rule out pregnancy or malignancy. If both pregnancy and pathology have been excluded, time or a change to another preparation may solve the problem Changing to an oral contraceptive with a higher estrogen content, while potentially useful in minimizing menstrual irregularity, should be done only if necessary since this may increase the risk of thromboembolic disease Breakthrough bleeding and spotting are sometimes encountered in patients on oral contraceptives, especially during the first three months of use Non-hormonal causes should be considered and adequate diagnostic measures taken to rule out malignancy or pregnancy in the event of breakthrough bleeding, as in the case of any abnormal vaginal bleeding. If pathology has been excluded, time or a change to another formulation may solve the problem.
If a patient has had daily bleeding since starting combined birth control 3 months ago, the first step is to rule out pregnancy or malignancy. If both are excluded, the patient's dosing may be adjusted by either:
- waiting to see if the bleeding resolves on its own
- changing to another preparation It is also possible to change to an oral contraceptive with a higher estrogen content, but this should be done with caution as it may increase the risk of thromboembolic disease 2, 2.
From the Research
Changing Combined Birth Control Dosing
To address daily bleeding in a patient who has been experiencing it since starting combined birth control 3 months ago, several options can be considered:
- Increasing the estrogen content from 20 mcg to 35 mcg per day may help reduce bleeding, as suggested by 3.
- Decreasing the hormone-free interval from seven to four or five days in people using cyclic contraception may also be beneficial, as noted in 3.
- For continuous combined contraception users, adding a hormone-free interval of four or five days can help regulate bleeding patterns, according to 3.
- It's also important to consider that unscheduled bleeding is more common during the early months of combined oral contraceptive use, and counseling patients about the possibility of unscheduled bleeding and the importance of adherence to the pill regimen can improve compliance, as mentioned in 4.
Factors to Consider
When evaluating the patient's situation, it's crucial to:
- Rule out other potential causes of abnormal uterine bleeding, as advised in 3.
- Consider the patient's individual response to the current contraceptive method and any potential side effects, as discussed in 5 and 6.
- Be aware that different formulations of combined oral contraceptives may have varying effects on bleeding patterns, as noted in 5, 6, and 7.
