Kariva is an estrogen and progestin combination which is used in the prevention of pregnancy. This type of oral contraceptive works by preventing ovulation each month. In addition, it also thickens the lining of the uterus so that if ovulation does occur (when more than 24 hours passed between 2 pills), it would still be difficult for the sperm to reach the egg.
Kariva comes in the form of an oral tablet which must be taken daily, at approximately the same time everyday. Missing a pill will increase the likeliness of pregnancy. Kariva , as with most other types of oral contraceptives, does not protect against the spread of sexually transmitted diseases .
Some of the common side effects users may experience when taking Kariva include vomiting, headache, breast tenderness, irregular menstrual periods and weight changes. If you experience more severe symptoms, contact your doctor immediately.
