Cigarette smoking increases the risk of serious cardiovascular side effects from oral contraceptive use. This risk increases with age and with heavy smoking (15 or more cigarettes per day) and is quite marked in women over 35 years of age. Women who use oral contraceptives are strongly advised not to smoke.
June l 21 and Junel Fe 28 are progestogen-estrogen combinations. Junel Fe 1/20 and 1.5/30: Each provides a continuous dosage regimen consisting of 21 oral contraceptive tablets and seven ferrous fumarate tablets. The ferrous fumarate tablets are present to facilitate ease of drug administration via a 28-day regimen, are non-hormonal, and do not serve any therapeutic purpose. Each light yellow tablet contains norethindrone acetate (17α-ethinyl-19-nortestosterone acetate), 1 mg; ethinyl estradiol (17α-ethinyl-1,3,5(10)-estratriene-3, 17β-diol), 20 mcg.
June l 21 and Junel Fe 28 are indicated for the prevention of pregnancy in women who elect to use oral contraceptives as a method of contraception.

Effect of the bile acid sequestrant colesevelam on the pharmacokinetics of pioglitazone, repaglinide, estrogen estradiol, norethindrone, levothyroxine, and glyburide. [2010.05]
The purpose of this study was to assess effects of colesevelam on the pharmacokinetics of glyburide, levothyroxine, estrogen estradiol (EE), norethindrone (NET), pioglitazone, and repaglinide in healthy volunteers. Six drugs with a potential to interact with colesevelam were studied in open-label, randomized clinical studies.
Does hormone therapy improve age-related skin changes in postmenopausal women? A randomized, double-blind, double-dummy, placebo-controlled multicenter study assessing the effects of norethindrone acetate and ethinyl estradiol in the improvement of mild to moderate age-related skin changes in postmenopausal women. [2008.09]
BACKGROUND: In postmenopausal women, declining estrogen levels are associated with a variety of skin changes, many of which are reportedly improved by estrogen supplementation. OBJECTIVE: A study was conducted to assess the effects of continuous combined norethindrone acetate (NA) and ethinyl estradiol (EE) in the control of mild to moderate age-related skin changes in postmenopausal women... CONCLUSION: Low-dose hormone therapy for 48 weeks in postmenopausal women did not significantly alter mild to moderate age-related facial skin changes.
Combined continuous ethinyl estradiol/norethindrone acetate does not improve forearm blood flow in postmenopausal women at risk for cardiovascular events: a pilot study. [2007.09]
OBJECTIVE: This study sought to determine whether combined continuous ethinyl estradiol and norethindrone acetate, a postmenopausal hormone therapy (HT) combination designed to have fewer side effects than cyclical therapies and therapies using medroxyprogesterone acetate (MPA), could improve vascular endothelial function in postmenopausal women with risk factors for cardiovascular disease (CVD)... CONCLUSIONS: In this older postmenopausal population with at least one cardiovascular risk factor, treatment with combined continuous ethinyl estradiol and norethindrone acetate failed to improve vascular endothelial function. The agent's proinflammatory effect or subclinical atherosclerosis in this population may have contributed to this finding.
Efficacy and safety of a new 24-day oral contraceptive regimen of norethindrone acetate 1 mg/ethinyl estradiol 20 micro g (Loestrin 24 Fe). [2007.01]
BACKGROUND: New low-dose formulations of combination oral contraceptives (COCs) are safe and effective, but they may be associated with an increased risk of breakthrough bleeding. Extending the duration of active hormonal treatment may reduce the frequency of intracyclic bleeding/spotting while maintaining efficacy and tolerability... CONCLUSIONS: NETA/EE-24 is an effective well-tolerated COC that is associated with a bleeding profile more favorable than that of NETA/EE-21.
Impact of combined estradiol and norethindrone therapy on visuospatial working memory assessed by functional magnetic resonance imaging. [2006.11]
CONTEXT: Hormones regulate neuronal function in brain regions critical to cognition; however, the cognitive effects of postmenopausal hormone therapy are controversial. OBJECTIVE: The goal was to evaluate the effect of postmenopausal hormone therapy on neural circuitry involved in spatial working memory... CONCLUSIONS: Hormone therapy was associated with more effective activation of a brain region critical in primary visual working memory tasks. The data suggest a functional plasticity of memory systems in older women that can be altered by hormones.
Clinical Trials Related to Junel (Norethindrone / Estradiol)
Study of Loestrin 24(24 Days of "Real" Pills) Fe Versus Loestrin 1/20 (21 "Real" Pills) [Completed]
The purpose of this research study is to assess hormone withdrawal symptoms in women while
taking an oral contraceptive in the novel 24/4 (24 days of "real" pills) manner in
comparison to taking pills in the standard 21/7 (21 "real" pills) manner.
It is hypothesized that the 24/4 method will reduce common hormone withdrawal symptoms
compared to the standard 21/7 regimen.
It is further hypothesized that women using the 24/4 regimen will report greater
A Drug-drug Interaction Study Between BMS-663068 and Oral Contraceptives in Healthy Female Volunteers [Recruiting]
This is an open-label, single sequence, 4-cycle, 4-treatment, drug-drug interaction (DDI)
study in healthy female subjects on oral contraceptives (OC). There is no formal research
hypothesis to be statistically tested. It is expected that coadministration of BMS-663068
with OC will not affect the pharmacokinetics (PK) of either ethinyl estradiol (EE) or
