What Are Warnings and Precautions for Drospirenone?

Contraindications

Effects of drug abuse

  • None

Short-Term Effects

  • See “What Are Side Effects Associated with Using Drospirenone?”

Long-Term Effects

  • See “What Are Side Effects Associated with Using Drospirenone?”

Cautions

  • Use leads to decreased estradiol serum levels; unknown if clinically relevant loss of bone mineral density may occur
  • Some studies suggest COC containing progestin and estradiol is associated with an increased risk of cervical cancer or intraepithelial neoplasia; however, controversy continues about the extent to which such findings may be due to differences in sexual behavior and other factors
  • Discontinue if jaundice or acute or chronic disturbances of liver function develop; do not resume until LFTs return to normal and causation identified; drospirenone contraindicated with hepatic impairment or benign or malignant liver tumors
  • Consider the possibility of ectopic pregnancy in women who become pregnant or report lower abdominal pain
  • Progestins may decrease insulin sensitivity; patients with diabetes may be at greater risk of hyperglycemia and may require additional medication adjustments or monitoring
  • Bleeding irregularities (.g, breakthrough or tetracyclic bleeding or spotting) may occur, especially during the first 3 months; may resolve over time or by changing to a different contraceptive; if persists, evaluate for causes (.g, pregnancy, malignancy)
  • Carefully observe females for the history of depression and discontinue drospirenone if depression recurs to a serious degree
  • Thromboembolic risk
    • Thromboembolism risk with combined oral contraceptives containing drospirenone and Ethinyl estradiol higher than those containing some other progestins plus Ethinyl estradiol
    • Epidemiological studies have not indicated an association between progestin-only preparations and an increased risk of myocardial infarction, cerebral thromboembolism, or venous thromboembolism
    • Discontinue if arterial or venous thromboembolic events occur; consider discontinuing prolonged immobilization due to surgery or illness
  • Hyperkalemia
    • Drospirenone has antimineralocorticoid activity, including the potential for hyperkalemia in high-risk females, comparable to spironolactone 25 mg
    • Contraindicated in females with conditions that predispose to hyperkalemia (e.g., renal impairment, hepatic impairment, adrenal insufficiency, long-term coadministration with strong CYP3A4 inhibitor)
  • Drug interaction overview
  • Effects of another drug on hormonal contraception
    • Drugs or herbal products that induce certain enzymes, including CYP3A4, may decrease systemic concentrations of hormonal contraceptives and potentially diminish the effectiveness or increase breakthrough bleeding
    • Instruct women to use a nonhormonal backup contraceptive for 28 days after discontinuing the enzyme inducer
    • Strong CYP3A4 inhibitors may result in a moderate increase of drospirenone systemic exposure
  • Effects of drospirenone on other drugs
    • Potential for increased serum potassium concentration if drospirenone is coadministered with other drugs that increase potassium levels

Pregnancy & Lactation

  • Based on epidemiologic studies and meta-analyses, there is little or no increased risk of birth defects in the children of females who inadvertently use oral progestins during early pregnancy
  • Discontinue if pregnancy occurs, as there is no reason to use hormonal contraceptives during pregnancy
  • Human data
    • Epidemiologic studies and meta-analyses have not found an increased risk of genital or nongenital birth defects (including cardiac anomalies and limb-reduction defects) following maternal use of oral progestins before conception or during early pregnancy
  • Lactation
    • Negligible amounts of drospirenone are excreted in the breast milk
    • At therapeutic doses, no effects on breastfed newborns/infants are anticipated
  • Human data
    • After daily administration of 4 mg, the average drospirenone concentration in breast milk over 24 hours is 5.6 ng/mL
    • Based on this concentration, the estimated average infant daily dosages for an exclusively breastfed infant are 840 ng/kg/day (relative infant dose is 1.5%)
