What If I Miss a Dose of Kariva?

Missing doses of Kariva increases the risk of pregnancy. What you should do depends on how many tablets you have missed and where exactly you are in your cycle (see Kariva Dosing). If you are not sure what to do, refer to the patient information that comes with each pack of Kariva, or consult your healthcare provider.
 

How Does It Work?

Kariva is a combined oral contraceptive, which means that it is a birth control pill that contains two different types of hormones. It contains both an estrogen (ethinyl estradiol) and a progesterone (desogestrel). Most importantly, the hormones in Kariva prevent pregnancy by stopping ovulation (the maturation and release of eggs from the ovaries). However, it also works to prevent pregnancy in two other, less important ways. Kariva changes the cervical mucus (the fluid of the cervix, which is the lower, narrow part of the uterus that is connected to the vagina), making it more difficult for sperm to enter the uterus. Lastly, Kariva alters the lining of the uterus (called the endometrium), making it less receptive to an embryo.
 
Most traditional birth control pills have 21 days of active pills (that contain the hormones), followed by 7 days of inactive pills (with no active ingredients). This gives your body a break from the hormones, causing you to have a period. Kariva has only two inactive tablets (plus five tablets with ethinyl estradiol) for the last week of the pack. These extra days with ethinyl estradiol (an estrogen) may decrease breakthrough bleeding (bleeding between periods).
