Long-Term Effects

Cautions
- Avoid using the diaphragm concomitantly; may interfere with ring placement
- Family history of breast cancer and or DVT/PE
- Use caution in current/history of depression, endometriosis, DM, HTN, bone mineral density changes, renal/hepatic impairment, bone metabolic disease, SLE; conditions exacerbated by fluid retention (. g, migraine, asthma, epilepsy)
- Known risk factors for VTE include smoking, obesity, and family history of VTE, in addition to other factors that contraindicate the use of CHCs; stop use if arterial thrombotic or venous thromboembolic event (VTE) occurs or if there is unexplained loss of vision, proptosis, diplopia, papilledema, or retinal vascular lesions; evaluate for retinal vein thrombosis immediately
- The risk of VTE is highest during the first year of CHC use and after restarting a CHC following a break of at least four weeks; the risk of VTE due to CHCs gradually disappears after use is discontinued
- Discontinue if the following develop jaundice, visual problems (may cause contact lens intolerance), migraine with unusual severity, significant blood pressure increase, severe depression, increased risk of thromboembolic complications after surgery
- Discontinue 4 weeks before major surgery or prolonged immobilization
- Discontinue if an arterial thrombotic or venous thromboembolic event occurs
- Estrogens may cause retinal vascular thrombosis; discontinue therapy if visual disturbances occur including migraine, loss of vision, diplopia, or proptosis
- Patients on warfarin, oral anticoagulants (increase in anticoagulant dose may be warranted)
- Increased risk of cervical cancer with OCP use, however, HPV remains the main risk factor for this cancer, evidence suggests long-term use of OCPs, 5 or more years, may be associated with increased risk
- Increased risk of liver cancer with OCP use; risk increases with longer duration of OCP use
- Combination of hormonal contraceptives may affect lipoprotein levels and serum triglycerides
- Use of CHCs may worsen existing gallbladder disease; history of CHC-related cholestasis predicts an increased risk with subsequent CHC use; women with a history of pregnancy-related cholestasis may be at increased risk for CHC-related cholestasis
- Use caution in patients with diseases that may be exacerbated by fluid retention including migraine, diabetes, renal dysfunction, and epilepsy
- CDC guidelines recommend waiting at least 4 weeks following vaginal birth, in women who are not breastfeeding, or 6 weeks after cesarean section to decrease the risk for venous thromboembolism before initiating combined hormonal contraceptives; women with additional risk factors for VTE (besides postpartum) should not use combined hormonal contraceptives (MMWR July 7, 2011)
- The risk of postpartum thromboembolism decreases after the third postpartum week, whereas the risk of ovulation increases after the third postpartum week
- Ring may not be suitable for women with conditions that make the vagina more susceptible to vaginal irritation or ulceration; vaginal/cervical erosion or ulceration in women reported; in some cases, the ring adhered to vaginal tissue, necessitating removal by a healthcare provider and in some instances (. e, when tissue had grown over ring), removal was achieved by cutting the ring without incising the overlying vaginal tissue
- Cases of toxic shock syndrome (TSS) have been reported by NuvaRing users; TSS has been associated with tampons and certain barrier contraceptives, and, in some cases, the patients were also using tampons; a causal relationship between the use of product and TSS has not been established; if a patient exhibits signs or symptoms of TSS, consider the possibility of this diagnosis and initiate appropriate medical evaluation and treatment
- Do not use the product in women with liver disease such as acute viral hepatitis or severe (decompensated) cirrhosis of the liver; acute or chronic disturbances of liver function may necessitate the discontinuation of CHC use until markers of liver function return to normal and CHC causation has been excluded; discontinue use if jaundice develops
- Risk of liver enzyme elevations with concomitant hepatitis C treatment reported; discontinue use before starting therapy with combination drug regimen ombitasvir/paritaprevir/ritonavir, with or without dasabuvir; the drug can be restarted approximately 2 weeks following completion of treatment with the Hepatitis C combination drug regimen
- Increase in blood pressure reported in women using CHCs; this increase is more likely in older women and with extended duration of use; incidence of hypertension increases with increasing concentrations of progestin; for women with well-controlled hypertension, monitor blood pressure and stop use if blood pressure rises significantly
- Hypersensitivity reactions of anaphylaxis and angioedema reported; if anaphylaxis and/or angioedema suspected, discontinue use and administer appropriate treatment
- Carefully monitor prediabetic and diabetic women who are using the product; CHCs may decrease glucose tolerance
- Consider alternative contraception for women with uncontrolled dyslipidemia; some women will have adverse lipid changes while on CHCs
- Women with hypertriglyceridemia, or a family history thereof, may be at increased risk of pancreatitis when using CHCs
- If a woman develops new headaches that are recurrent, persistent, or severe, evaluate the cause and discontinue if indicated
- Consider discontinuation in the case of an increased frequency or severity of migraine during CHC use (which may be prodromal of a cerebrovascular event)
- Breast cancer
- Epidemiology studies have not found a consistent association between the use of combined oral contraceptives (COCs) and breast cancer risk; studies do not show an association between every (current or past) use of COCs and the risk of breast cancer
- Some studies report a small increase in the risk of breast cancer among current or recent users (below 6 months since last use) and current users with longer duration of COC use
- A woman's risk depends on conditions where naturally high hormone levels persist for long periods including early-onset menstruation before age 12, late-onset menopause, after age 55, first child after age 30, nulliparity
Pregnancy and Lactation
- Extensive epidemiological studies have revealed no increased risk of birth defects in women who have used oral contraceptives before pregnancy; studies also do not suggest a teratogenic effect, particularly insofar as cardiac anomalies and limb reduction defects are concerned, when taken inadvertently during early pregnancy
- Administration of oral contraceptives to induce withdrawal bleeding should not be used as a test for pregnancy; oral contraceptives should not be used during pregnancy to treat threatened or habitual abortion
- It is recommended that for any patient who has missed two consecutive periods, pregnancy should be ruled out before continuing oral contraceptive use; if the patient has not adhered to the prescribed schedule, the possibility of pregnancy should be considered at the time of first missed period; oral contraceptive use should be discontinued if pregnancy is confirmed
- Lactation
- Small amounts of oral contraceptive steroids were identified in the milk of nursing mothers, and a few adverse effects on child reported, including jaundice and breast enlargement; in addition, oral contraceptives given in the postpartum period may interfere with lactation by decreasing the quantity and quality of breast milk
- If possible, the nursing mother should be advised not to use oral contraceptives but to use other forms of contraception until she has completely weaned her child
