continuous hormones or has placebo pills only every 84 days
when taking prednisone and oral bc what happens?
decrease efficacy of OCC and increased prednisone ADRs
when taking valproic acid and oral bc what happens?

An otherwise healthy 25 year old nulliparous woman has just been diagnosed with a lower extremity deep venous thrombus (DVT) after orthopedic surgery. She has been placed on therapeutic anticoagulation for treatment. Up until this point, she had been taking a combined oral contraceptive pill. She presents to her gynecologist for contraceptive counseling. The best next step is: A.Discontinuation of combined oral contraceptive until anticoagulation therapy is complete B.Transition to an oral contraceptive pill containing a lower dose of estrogen C.Transition to levonorgestrel IUD D.Transition to copper IUD E.Continue current combined oral contraceptive
(C) Transition to levonorgestrel IUD. i guess copper isn't first line because it is can increase bleeding
Your patient, who is taking an oral contraceptive, has heard about and asks about the risk of thromboembolism as a result of taking these drugs. To reduce the risk of this potentially severe adverse hematologic response, but still provide reasonably effective contraception, what would you prescribe? A.A combination product with a higher estrogen dose B.A combination product with a higher progestin dose C.A combination product with a lower estrogen dose D.A combination product with a lower progestin dose E.A product that contains only estrogen
A combination product with a lower estrogen dose estrogen=what is the main cause of the clotting
Which of the following patients is the best candidate for combined oral contraceptives? A. 45-year-old with a family history of breast cancer B. 37-year-old smoker C. 32-year-old with a history of a pulmonary embolism during her most recent pregnancy D. 25-year-old with a history of migraines with aura 38-year old with hepatocellular carcinoma
A-family hx of breast cancer seems odd but I guess if you dont have the cancer it's just a family hx it's okay
A woman has been sexually assaulted and she wishes to have her pregnancy terminated by pharmacologic means. What is generally the most appropriate drug? A.Levonorgestrel B.Methotrexate C.Mifepristone D.Ulipristal E.Copper IUD
A.Levonorgestrel B.Methotrexate C.Mifepristone D.Ulipristal E.Copper IUD Progesterone antagonist: not the same as emergency contraception. Once the zygote has been implanted, EC is not effective (hence the decreasing efficacy with increasing time after unprotected intercourse)
Which of the following would be indications for seeking medical care after taking emergency contraception? A. Menses over two weeks late B. Abdominal pain C. Irregular bleeding D. All of the above E. None of the above
ALL OF THE ABOVE
Oral Contraceptive Danger Signs...points to counsel on when to see medical attention

Your patient is a 38-year-old G2P2 female with type 2 diabetes mellitus for 2 years that is controlled with metformin. She presents for her annual gyn exam and request a prescription for oral contraceptive pills. She smokes heavily quoting around 2 packs per day. Her family history is significant for CVA (mother). When you are deciding to prescribe an oral contraceptive to this patient, which of the following will prompt serious consideration of whether or not to recommend another method of contraception? A.Parity B.Smoking C.Physical Activity D.Diabetes Serum HDL
B-smoking, more than 15 a day
A 23 year old nulliparous patient presents for contraceptive counseling. She is about to start medical school and does not plan on getting pregnant for many years. Her past medical history is notable for epilepsy, first diagnosed as a child. She has been on various medications to control her symptoms over the years but has been well controlled on carbamazepine for the last two years. You review the failure rate of oral contraceptives, depo medroxyprogesterone acetate (DMPA), and intrauterine device (IUD) contraception among the general population. She prefers oral contraception. Given her history of epilepsy you recommend intrauterine device contraception because: A. The metabolic interaction between antiepileptic and oral contraception is harmful to the liver B. The metabolic interaction between antiepileptic and oral contraception reduces the effectiveness of the OC C. The metabolic interaction between antiepileptic and oral contraception results in increased seizure activity D. Epileptic patients are a higher risk of stroke when taking estrogen E. Epileptic patients are at higher risk of clot when taking estrogen
B. The metabolic interaction between antiepileptic and oral contraception reduces the effectiveness of the OC
Drugs that induce 3A4 lower the concentration of the birth control=less effective, what are some drugs that induce 3A4?
Barbiturates carbamazepine topiramate corticosteroids griseofulvin phenytoin pioglitazone modafinil armodafinil, rifampin, and rifabutin, etc. induce 3A4 (i.e., metabolize estrogens and progestins quicker)
A women who has been taking an oral combined contraceptive pill for several years is diagnosed with epilepsy and started on phenytoin. What is the most likely consequence of adding phenytoin? A.Breakthrough seizures from increased phenytoin clearance B.Phenytoin toxicity C.Reduced contraceptive efficacy D.Thromboembolism from the estrogen component of the contraceptive E.Thromboembolism from the progestin component of the contraceptive
C.Reduced contraceptive efficacy
Drospirenone has a BBW, what is it?
Cigarette smoking increases the risk of serious cardiovascular events from oral contraceptive use. This risk increases with age, particularly in women over 35 years of age, and with the number of cigarettes smoked. Women who are over 35 years of age and smoke should not use oral contraceptives
A 25 year old woman has just undergone Roux-en-Y gastric bypass surgery and presents to your clinic requesting contraception. Medical history is negative for hypertension and headache, and notable only for acne and irregular vaginal bleeding secondary to known submucosal uterine fibroids. She is mutually monogamous with one male partner. The BEST contraceptive method for this patient is: A.Combination oral contraceptive pill B. Progestin-only contraceptive pill C. Copper IUD D. Etonogestrel subdermal implant E. Levonorgestrel IUD
Correct answer: (D) Etonogestrel subdermal implant. Oral contraceptives should be avoided in women who have had malabsorptive bariatric surgeries. IUDs may be at higher risk for expulsion in women who have uterine cavities distorted by submucosal fibroids.
A 27-year-old G0 with a copper intrauterine device (IUD) placed 2 years ago presents to the emergency room with severe pelvic pain, fever, nausea, and vomiting. An ultrasound demonstrates fundal placement of the IUD, with normal adnexae. She is diagnosed with pelvic inflammatory disease (PID), and the plan is to admit her for IV antibiotics. How should the IUD be managed? A. The IUD should be removed immediately after the diagnosis of PID is made B. The IUD should be removed after her first dose of IV antibiotics to reduce the patient's risk of bacteremia C. The IUD can be left in place until she has defervesced, then it should be removed D. The IUD can be left in place with consideration of removal only if she does not respond to antibiotics
Correct answer: (D) The IUD can be left in place with consideration of removal only if she does not respond to antibiotics. Explanation: The risk of PID with an IUD in place is quite small. Treatment of PID does not require IUD removal, and routine antibiotics should be administered in this case. If 48-72 hours pass without clinical improvement, IUD removal can be considered, but it has not been shown to improve outcomes in that setting.
A women wants a prescription for an oral contraceptive, and your choice is between an estrogen-progestin combination and a 'minipill'(progestin only). Compared with a hormone combination product, what is the main difference that would occur when a progestin-only approach is used? A.Better contraceptive efficacy B.Direct spermicidal effects C.Higher risk of thromboembolism D.More menstrual irregularities E.Poorer compliance due to taking the drug on an irregular cycle, rather than daily
D.More menstrual irregularities
how would you manage estrogen excess
Decrease estrogen content, consider progestin only or IUD quick cycle aka continous regimen NSAIDS for dysmenorrhea
How do you treat progestin excess??
Decrease progestin content choose less androgenic progestin
A 37-year-old female is interested in oral contraception. She is newly married and sexually active with her husband. She has 2 children from a previous relationship and does not desire any children.

This patient is at risk for which of the following complications if she starts combined oral contraceptives? A.Hypertension B.Endometrial carcinoma C.Trichomoniasis D.Unwanted pregnancy E.Deep Venous Thrombosis
Deep Venous Thrombosis
Progestin Deficiency adverse effects
Dysmenorrhea, menorrhagia (progesterone antagonizes estrogen so sx here are related to excess estrogen action) Late cycle (days 10-21) breakthrough bleeding or spotting
According to the CDC Medical Eligibility Criteria for Contraceptive Use, which of the following contraceptive methods is contraindicated in women with a history of ovarian cancer (not actively undergoing treatment)? A.Depot medroxyprogesterone acetate injection B. Etonogestrel subdermal implant C. Copper IUD D. Levonorgestrel IUD E. None of the above
E. None of the above also strange, I feel like if someone has a hx I am probably not gonna mess with hormones but for this test know it's okay
How can you manage estrogen deficiency?
Exclude pregnancy increase estrogen content or continue current if amenorrhea is acceptable
At her first gyn visit a 22 year old woman asks for birth control pills. Her cycle is regular, every 28-31 days, she has a heavy flow, lasting for about 5 days.

In addition to being used for daily contraception prevention, paragard can be used for
emergency contraception paced within 5 days
MOA of combined oral contraceptives
•Prevents ovulation by Suppressing the follicle-stimulating hormone-luteinizing hormone (FSH-LH) sequence from the anterior pituitary •Estrogens: suppresses FSH and inhibits the maturation of dominant follicle •Progestins: suppresses LH surge, inhibits endometrial proliferation and thickens cervical mucus
