TopSide Effects by Body System
Endocrine
Endocrine side effects have included breast tenderness, galactorrhea with or without hyperprolactinemia, prevention of lactation, hirsutism, and Cushing's syndrome.
Cushing's syndrome is uncommon and appears to be associated with a long duration of therapy and moderate to high doses of medroxyprogesterone. Doses used for hormonal replacement therapy and for long-term contraception are not associated with Cushing's syndrome.
Medroxyprogesterone has mild glucocorticoid activity. In cases of medroxyprogesterone-induced Cushing's syndrome, low cortisol and adrenocorticotrophic hormone (ACTH) levels with a reduced pituitary-adrenal reserve have been documented. Acute adrenal insufficiency may ensue following withdrawal of medroxyprogesterone.
Metabolic
Weight gain is more frequently encountered than weight loss during medroxyprogesterone therapy. In women using intramuscular medroxyprogesterone for contraception, the mean weight gain after one year of therapy is 2.5 kg. After two, four, and six years, patients gain a mean of 3.7, 6.3, and 7.5 kg, respectively.
Data regarding the effect of medroxyprogesterone on lipid profiles have been conflicting. Some studies report possible negative effects on lipid profiles while others have documented a reduction in total and low-density lipoprotein cholesterol and an increase in high-density lipoprotein cholesterol levels.
Metabolic side effects have included weight changes (increases and decreases), glucose intolerance, and changes in serum cholesterol concentrations.
Genitourinary
Withdrawal bleeding is a common complaint among postmenopausal women receiving sequential (10 to 14 days per cycle) medroxyprogesterone therapy. In postmenopausal women receiving continuous medroxyprogesterone and estrogen therapy, 75% or more are amenorrheic by one year of therapy.
In women receiving medroxyprogesterone for contraception, more than 50% are amenorrheic by one year of therapy.
In women on estrogen replacement therapy, the addition of medroxyprogesterone or other progestin for at least 10 to 14 days of each cycle significantly reduces the risk of endometrial hyperplasia and, thus, the risk of endometrial carcinoma. Low-dose continuous medroxyprogesterone therapy also reduces the risk of endometrial hyperplasia associated with the use of unopposed estrogen.
In patients in whom abnormal bleeding persists or is severe, the possibility of an organic pathology should be considered and ruled out.
Genitourinary side effects have been relatively common and included primarily menstrual changes such as amenorrhea, irregular bleeding, spotting, and heavy bleeding. Vaginal cysts, dyspareunia, and changes in cervical erosion and secretions have also been reported. While endometrial hyperplasia has been reported, medroxyprogesterone tended to have a favorable effect on the endometrium. Changes in libido and anorgasmia have also occurred.
Oncologic
A significant increase in the incidence of breast cancer in beagle dogs in addition to an apparent increase in the incidence of endometrial cancer in rhesus monkeys was noted in early animal carcinogenicity studies.
International long-term studies designed to assess the risk of medroxyprogesterone in humans, sponsored by the World Health Organization, failed to find an increased risk of cancer in users of medroxyprogesterone. Overall, there was no significant increase in the risk of breast cancer, cervical cancer, or epithelial ovarian cancer. Data from these studies did, however, support a significant (8-fold) reduction in the incidence of endometrial cancer among medroxyprogesterone users.
A study from New Zealand has suggested that women taking depot medroxyprogesterone acetate may be at higher risk for breast cancer during the first 5 years, but therapy for more than 5 years confers no increased risk of breast cancer.
Oncologic side effects possibly associated with medroxyprogesterone have been the topic of considerable debate. Data from some animal studies suggested an increased risk of breast and endometrial cancer. The current consensus is that the carcinogenic potential of medroxyprogesterone is no greater than that of other hormonal contraceptives.
Cardiovascular
The majority of cases of thromboembolic disease during hormonal therapy have been attributed to estrogens and not to progestins. However, it has been demonstrated that medroxyprogesterone, at least at high doses, can produce a hypercoagulable state. Whether or not this contributes to the development of thrombotic events remains unknown.
Because medroxyprogesterone can cause edema, it should be used cautiously in patients with underlying disease (like migraine headaches, asthma, heart disease, renal dysfunction, or seizure disorders) which may be exacerbated by edema or fluid retention.
Cardiovascular side effects have included thromboembolic disorders such as thrombophlebitis, deep vein thrombosis, pulmonary embolism, cerebrovascular accidents, and retinal thrombosis. In addition, edema, hypertension, tachycardia, and syncope have been noted.
Musculoskeletal
Musculoskeletal side effects have included changes in bone mineral density and leg cramps.
Reductions in bone mineral density and osteoporosis have been attributed to medroxyprogesterone. Such effects are probably due to medroxyprogesterone-induced estrogen deficiency.
Conflicting data concerning the effects of medroxyprogesterone on bone mineral density have been reported.
In one study, women 25 to 51 years of age receiving medroxyprogesterone 150 mg intramuscularly every three months for five or more years for long-term contraception had a reduction in bone mineral density compared with premenopausal controls. However, bone mineral density in the treatment group was still significantly greater than that observed in postmenopausal controls.
A study of 200 women who received medroxyprogesterone 150 mg intramuscularly every three months for a median duration of 12 years (range 2 to 26 years) reported that bone density was significantly reduced in medroxyprogesterone users. However, bone mineral density in women starting depot medroxyprogesterone after the age of 20 years and using it for 15 or fewer years was greater than the remainder of the cohort.
A study to determine the potential for postmenopausal fracture due to residual effects of depot medroxyprogesterone in former users reported the risk to be small and unlikely to have substantial impact in postmenopausal women. No significant differences in bone density were found, however, women who had used depot medroxyprogesterone for >2 yeas had a trend toward lower bone densities.
Bone density in 185 women receiving long-term depot medroxyprogesterone for a mean of 5 years (range of 1-16 years) was only minimally below the normal population despite decreased estrogen levels.
Dermatologic
Dermatologic side effects have included acne, reduced hair growth, alopecia, melasma, chloasma, rash, excessive sweating, dry skin, scleroderma, erythema multiforme, and erythema nodosum.
Nervous system
Nervous system side effects have included headache, asthenia, dizziness, depression, somnolence, and insomnia. Paresthesias, convulsions, and facial palsy have been reported although causality is unknown.
Gastrointestinal
Gastrointestinal side effects have occurred in up to 5% of patients and included nausea, abdominal pain, bloating, and anorexia.
Hepatic
Hepatic side effects have included elevations in liver function tests, jaundice, cholestatic jaundice, and cholelithiasis.
Hematologic
Hematologic side effects have included rare reports of hypercoagulability with and without thromboembolic activity.
Hypersensitivity
Hypersensitivity side effects have been uncommon but have included urticaria, angioneurotic edema, and anaphylaxis or anaphylactoid reactions.
Local
Local side effects associated with intramuscular administration of medroxyprogesterone have included pain, change in skin color, residual lumps, and sterile abscesses at the injection site.
Ocular
Ocular side effects have included visual disturbances such as sudden loss of vision (partial or complete), sudden onset of proptosis, diplopia, or migraine have been reported. Therapy should be withdrawn in the presence of papilledema or retinal vascular lesions.
Psychiatric
Psychiatric side effects have included dysphoric symptoms similar to premenstrual syndrome (PMS).
