Jinteli (northindrone acetate and ethinyl estradiol) is a continuous dosage regimen of a progestin-estrogen combination used to treat moderate to severe vasomotor symptoms associated with menopause and to prevent postmenopausal osteoporosis. Common side effects of Jinteli include nausea, vomiting, stomach pain or upset, headache, bloating, breast tenderness or swelling, swelling of the ankles/feet (fluid retention), weight changes, changes in appetite, freckles or darkening of facial skin, increased hair growth, loss of scalp hair, problems with contact lenses, runny nose, vaginal itching or discharge, decreased sex drive, dizziness, or sleep problems. Vaginal bleeding between periods (spotting) or missed/irregular menstrual periods may occur, especially during the first few months of Jinteli use.
Jinteli therapy consists of a single tablet taken once daily. Jinteli may interact with cyclosporine, prednisolone, theophylline, other drugs containing estrogen such as birth control pills, acetaminophen, temazapam, salicylic acid, morphine, and clofibric acid. Tell your doctor all medications and supplements you use. Jinteli is not recommended for use during pregnancy. It may cause birth defects.

Jinteli FDA Prescribing Information: Side Effects
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The adverse reaction information from clinical trials does, however, provide a basis for identifying the adverse events that appear to be related to drug use and for approximating rates.
Adverse events reported in controlled clinical studies of norethindrone acetate and ethinyl estradiol are shown in Table 6 below.
