Progesterone Contraindications

Progesterone is absolutely contraindicated in patients with known or suspected breast cancer, active thromboembolic disease (DVT/PE), active arterial thrombotic disease (stroke, MI), undiagnosed abnormal vaginal bleeding, known liver dysfunction or disease, known pregnancy, and hypersensitivity to progesterone (including peanut allergy for peanut oil-containing formulations). 1

Absolute Contraindications

Based on FDA labeling and clinical guidelines, progesterone therapy must not be used in the following conditions 1:

Malignancy-Related

  • Known or suspected breast cancer (current or history) 1, 2
  • History of estrogen- or progestin-sensitive cancers 2
  • Carcinoma of the endometrium 2

Thromboembolic Conditions

  • Active deep vein thrombosis or pulmonary embolism 1
  • History of venous thromboembolic disease 1
  • Active arterial thromboembolic disease (stroke, myocardial infarction) 1, 2
  • History of arterial thrombotic events 1, 2

Hepatic Disease

  • Known liver dysfunction or disease 1, 2
  • Hepatic adenomas or carcinomas 2
  • Active hepatic disease 2

Other Absolute Contraindications

  • Undiagnosed abnormal genital bleeding 1, 2
  • Known pregnancy 1
  • Hypersensitivity to progesterone or its ingredients (particularly peanut allergy for formulations containing peanut oil) 1

Important Clinical Context: Progestin-Only vs. Combined Therapy

A critical distinction exists between progestin-only contraception and combined estrogen-progestin therapy. The French Society of Endocrinology guidelines clarify that many cardiovascular contraindications apply specifically to combined estrogen-progestin formulations, while progestin-only methods may be considered in certain high-risk situations 3.

When Progestin-Only May Be Considered (Despite Cardiovascular Risk)

In women with the following conditions, combined estrogen-progestin therapy is formally contraindicated, but progestin-only therapy may be considered 3:

  • Personal history of thromboembolic disease (after acute phase)
  • Documented biological thrombophilia without clinical events
  • Personal history of arterial events (coronary disease, stroke) - only after multidisciplinary consultation 3
  • Controlled or uncontrolled hypertension 3

Relative Contraindications and Cautions

Cardiovascular Risk Factors

  • Smoking in women ≥35 years of age (particularly with combined formulations) 2, 3
  • Uncontrolled hypertension (≥160/100 mmHg) - contraindication for combined therapy, caution for progestin-only 3
  • Family history of early cardiovascular events (before age 50) 3

Other Conditions Requiring Caution

  • Renal dysfunction or adrenal insufficiency (particularly with drospirenone-containing products) 2
  • Cardiac or renal conditions that may be influenced by fluid retention 1
  • Migraine headaches with focal neurologic symptoms or migraine with aura in women ≥35 years 2
  • Meningioma (use caution with progestogen monotherapy) 4

Special Populations

Gynecologic Cancer Survivors

The evidence shows nuanced recommendations 5:

  • Contraindicated: Low-grade serous epithelial ovarian cancer, granulosa cell tumors, certain sarcomas (leiomyosarcoma, stromal sarcoma), advanced endometrioid uterine adenocarcinoma
  • May be considered: Cervical, vaginal, vulvar cancers (not hormone-dependent), high-grade/clear cell/mucinous ovarian cancers, early-stage endometrial cancer

Women at High Risk for Breast Cancer

Women with BRCA1/2 mutations or strong family history should avoid exogenous sex hormones and proceed with extreme caution, requiring thorough risk-benefit assessment with a qualified specialist 6.

Common Pitfalls to Avoid

  1. Do not confuse progestin-only with combined estrogen-progestin contraindications - many cardiovascular contraindications are specific to combined formulations 3

  2. Always check for peanut allergy before prescribing progesterone capsules containing peanut oil 1

  3. Do not prescribe unopposed estrogen in women with intact uterus - this increases endometrial cancer risk and requires progestogen addition 7

  4. Measure blood pressure before prescribing any hormonal contraception - this is the only clinical examination recommended by WHO before starting treatment 3

  5. Screen for thrombophilia only in women with first-degree family history of thromboembolism before age 60 - routine screening is not indicated 3
