Kariva Information

Kariva

Oral contraceptives come in a variety of formulations. The main division is between combined oral contraceptive pills, containing both estrogen and synthetic progestogens (strictly progestins, the term used in the United States, but the former term is used in the United Kingdom), and progestogen only pills (mini-pills). Combined oral contraceptive pills also come in varying types, including varying doses of estrogen, and whether the dose of estrogen or progestogen changes from week to week.

Combination pills usually work by preventing a woman's ovaries from releasing eggs (ovulation). They also thicken the cervical mucus, which keeps sperm from joining with an egg. The hormones in combination and progestogen-only pills also thin the lining of the uterus. This could prevent pregnancy by interfering with implantation of a blastocyst.

Recent Kariva Side Effects

I have been on Kariva (generic for Mircette) birth control for about 6 years now, I started when I was a junior in high school because of all the symptoms associated with irregular cycles. For the first 3 years I believed it was a miracle drug because my ability to focus increased, my cramps were few and far between, and I felt less moody. BUT...increasingly now over the past couple years it seems like the pill is losing it's effects. I also started having horrible migraines at least once a month, sometimes twice...and my doctor was not sure why, so she decided to cut me off from the birth control "just in case" and within a couple weeks I became very emotional, had cramps, and had trouble focusing in my college classes. I went back to my doctor and she put me right back on the pill...but it seems like ever since that happened, I haven't fully gotten back to the state I was in before the migraines started. After seeing this thread, I am wondering if withdrawal may be the cause of how my body and mind felt after going off the birth control...maybe if I had held out longer, those symptoms would have died off. OR, maybe the birth control dosage needs to be increased, but I'm worried that could make things worse or increase dependency later on. Does anyone have advice about what would be the best course of action? My doctor seems smart, but I feel like no one really knows the answer to fixing "myself", to feeling at least sane again...and I really need these migraines to go away because they are getting worse and becoming very hard to handle emotionally, and physically...and financially.

Kariva Chemical Information

desogestrel - A synthetic progestogen with progesterone hormone receptor agonistic activity. Desogestrel binds intracellular progesterone receptors in progesterone responsive tissue and the resultant complex interacts with DNA and results in either gene transcription or gene repression. This leads to an inhibition of LH release and prevents ovulation and alters the cervical mucus. Desogestrel is used in birth control pills alone or in combination with estrogens.

ethinyl estradiol - A semisynthetic estrogen. Ethinyl estradiol binds to the estrogen receptor complex and enters the nucleus, activating DNA transcription of genes involved in estrogenic cellular responses. This agent also inhibits 5-alpha reductase in epididymal tissue, which lowers testosterone levels and may delay progression of prostatic cancer. In addition to its antineoplastic effects, ethinyl estradiol protects against osteoporosis. In animal models, short-term therapy with this agent has been shown to provide long-term protection against breast cancer, mimicking the antitumor effects of pregnancy. (NCI04)
