Lo/Ovral-28 (norgestrel and ethinyl estradiol) Tablets is a combination of female hormones used as contraception to prevent pregnancy. Lo/Ovral-28 is available in generic form. Common side effects of Lo/Ovral-28 include nausea (especially when you first start taking Lo/Ovral-28), vomiting, headache, stomach cramping, bloating, dizziness, vaginal discomfort/irritation/itching, increased vaginal fluids/discharge, breast tenderness or enlargement, nipple discharge, freckles or darkening of facial skin, increased hair growth, loss of scalp hair, changes in weight or appetite, problems with contact lenses, or decreased sex drive. Acne may improve or get worse. Vaginal bleeding between menstrual periods (spotting) or missed/irregular periods may occur, especially during the first few months of use.
Dose of Lo/Ovral is one tablet daily for twenty-one consecutive days, beginning on the first day (Day 1 Start) of the menstrual cycle or on the Sunday after the period begins (Sunday Start). The tablets are then discontinued for one week (7 days). Withdrawal bleeding usually occurs within 3 days following discontinuation of Lo/Ovral and may not finish before the next pack is started. Follow pack instructions. Lo/Ovral may interact with acetaminophen, ascorbic acid (vitamin C), modafinil, dexamethasone, antibiotics, seizure medicines, or HIV medicines. Tell your doctor all medications you use. Lo/Ovral must not be used during pregnancy. If you have just given birth or had a pregnancy loss/abortion after the first 3 months, talk with your doctor about birth control, and find out when it is safe to use birth control containing estrogen, such as this medication. This medication passes into breast milk. This may affect milk production and may have undesirable effects on a nursing infant. Consult your doctor before breastfeeding.
