For adult hypothyroidism, levothyroxine is started at -125 mcg/day administered orally. Starting doses and dose changes may differ with individual patients based upon age, the presence of cardiovascular disease , the development of tolerance (reduced effectiveness with continued use), side effects to the medication, and blood levels of thyroid hormone. It may take one to three weeks after initiating therapy with levothyroxine or changing the dose before effects are seen. The goal of replacement therapy is to maintain a normal blood thyroxine level.
Most oral contraceptives (birth control pills) combine estrogen and progestin (natural or synthetic progesterone), but some contain only progestin. Examples of progestin-only contraceptives include the Norplant implant and the Depo-Provera contraceptive device. Progestin aids in preventing ovulation, alters the lining of the uterus, and thickens cervical mucus -- processes that help to prevent conception and implantation. The estrogen in birth control pills prevents egg production. Oral contraceptives have many side effects, so their use should be discussed with a physician.
