From the Guidelines
Combination oral contraceptive pills (COCs) are not recommended for patients with chronic kidney disease (CKD) due to the increased risk of thromboembolism, worsening blood pressure control, and potential exacerbation of volume overload issues. The estrogen component in COCs can increase the risk of thromboembolism, which is already elevated in CKD patients due to their prothrombotic state 1. CKD patients often have hypertension, and estrogen can worsen blood pressure control, potentially accelerating kidney damage, as seen in conditions with systolic blood pressure ≥160 mm Hg or diastolic ≥100 mm Hg, which are classified as category 4 1. Additionally, fluid retention caused by estrogen may exacerbate volume overload issues common in CKD. The altered drug metabolism in kidney disease can lead to unpredictable hormone levels and side effects. For CKD patients requiring contraception, progestin-only methods like the mini-pill, depot medroxyprogesterone acetate injections, or levonorgestrel-releasing intrauterine devices are safer alternatives as they don't contain estrogen and pose fewer cardiovascular risks, similar to considerations for patients with a history of high blood pressure during pregnancy or those with vascular disease 1. Key considerations include:
- The severity of CKD, with patients having mild disease (stages 1-2) potentially tolerating COCs with careful monitoring, while those with moderate to severe CKD (stages 3-5) should generally avoid them completely.
- The importance of consulting with both nephrology and reproductive health specialists to balance contraceptive needs with kidney health considerations, taking into account the individual's risk factors and medical history, such as history of deep venous thrombosis (DVT) or pulmonary embolism (PE) 1.
From the FDA Drug Label
Women with a history of hypertension or hypertension-related diseases, or renal disease should be encouraged to use another method of contraception
The use of combination oral contraceptive pills (COCs) is not recommended in patients with chronic kidney disease (CKD) because they may have an increased risk of hypertension and renal disease progression. The FDA drug label advises that women with a history of renal disease should be encouraged to use another method of contraception.
- Key points:
- Increased risk of hypertension
- Potential progression of renal disease
- Alternative contraceptive methods recommended 2
From the Research
Combination Oral Contraceptive Pills in Chronic Kidney Disease
- Combination oral contraceptive pills (COCs) are not recommended in patients with chronic kidney disease (CKD) due to several reasons:
- Estrogen in COCs may exacerbate kidney damage, although estrogens have been shown to have nephroprotective effects in some cases 3.
- The use of COCs in CKD patients may increase the risk of thromboembolism and hypertension, particularly in those with proteinuria or immunologic disorders 4.
- CKD patients are at high risk of thrombosis and major bleeding events, and the use of COCs may further increase this risk 5, 6.
- Alternative contraceptive methods are available for CKD patients, including:
- Progestin-only pills, which are generally safe but may cause intramenstrual spotting 4.
- Non-medicated intrauterine devices, which are a good alternative but require careful evaluation in patients at high risk of pelvic infection 4.
- Barrier methods, which have few risks but require correct use to be effective 4.
Pharmacokinetics of Estrogen and Progesterone in CKD
- The pharmacokinetics of estrogen and progesterone are altered in CKD patients, with higher plasma concentrations of estradiol and estrone in women with end-stage renal disease (ESRD) 7.
- This alteration in pharmacokinetics may require dose adjustments for estrogen replacement therapy in CKD patients, with a recommended reduction of at least 50% in oral estradiol doses 7.
