Can a 36-year-old female with uncontrolled diabetes mellitus (DM) and no primary care provider, who is experiencing polyuria, polydipsia, and occasional blurred vision, safely receive a Depo-Provera (medroxyprogesterone acetate) injection?

Can This Patient Safely Receive Depo-Provera?

Yes, this patient can receive Depo-Provera today, but only after obtaining laboratory confirmation that her diabetes is not severely uncontrolled, and she must commit to immediate diabetes management and close follow-up. 1

Medical Eligibility for DMPA in Diabetic Patients

The U.S. Medical Eligibility Criteria for Contraceptive Use applies to DMPA administration, and diabetes itself is not an absolute contraindication to Depo-Provera. 2 However, the critical distinction lies in the degree of diabetes control and presence of vascular complications:

• Diabetes without vascular disease: DMPA is generally safe and can be prescribed 2
• Diabetes with vascular complications (nephropathy, retinopathy, neuropathy, or cardiovascular disease): DMPA carries increased risk and alternative contraception should be strongly considered 2

The Diabetes-DMPA Risk Profile

Evidence of Metabolic Effects

The relationship between DMPA and glucose metabolism is concerning in patients with pre-existing diabetes:

• DMPA approximately doubles insulin levels at 2-3 hours post-glucose challenge in metabolic studies, indicating worsened insulin resistance 3
• In Navajo women (a high-risk diabetes population), DMPA users had 3.8 times higher odds of developing diabetes compared to combination oral contraceptive users, with risk persisting after adjusting for BMI 4
• A case report documented a patient with lipodystrophy-related diabetes whose hemoglobin A1c was normal on leptin and metformin, but who developed severe hyperglycemia requiring up to 1,700 units of insulin daily after a single DMPA injection 5

Clinical Implications for This Patient

Your patient presents with classic symptoms of uncontrolled diabetes (polyuria, polydipsia, blurred vision) and admits to not monitoring glucose or receiving diabetes care. 2 This constellation suggests her diabetes may already have vascular complications, particularly given the blurred vision, which could represent diabetic retinopathy.

Absolute Contraindications to Rule Out

Before administering DMPA, you must confirm this patient does NOT have any of the following 1, 6:

• Active thrombophlebitis or thromboembolic disorders
• Cerebrovascular disease or history of stroke
• Myocardial infarction history
• Significant liver disease
• Undiagnosed vaginal bleeding
• Known or suspected breast cancer

The patient denies these conditions, but her uncontrolled diabetes significantly increases her cardiovascular risk, which is the primary concern here. 1

Required Pre-Administration Steps for This Patient

Immediate Laboratory Testing (Same-Day)

While CDC guidelines state that minimal pre-administration testing is typically required for DMPA 1, this patient's symptomatic uncontrolled diabetes changes the risk-benefit calculation. You should obtain:

• Hemoglobin A1c to quantify degree of diabetes control 7
• Basic metabolic panel to assess for diabetic ketoacidosis risk given her polyuria/polydipsia
• Urine pregnancy test to ensure she is not pregnant 1
• Consider lipid panel given cardiovascular risk assessment needs

Diabetes Screening for Vascular Complications

Given her blurred vision, you should assess for diabetic retinopathy, as this would reclassify her diabetes as having vascular complications 2:

• Dilated fundoscopic examination or referral to ophthalmology is indicated for any diabetic patient with visual symptoms 2
• The prevalence of diabetic retinopathy in adults with diabetes is 3.4%, and vision-threatening retinopathy affects 0.7% 2

Decision Algorithm for DMPA Administration

If laboratory results show:

1. A1c < 9% AND no evidence of vascular complications:

   • DMPA can be administered today 2, 1
   • Provide standard DMPA counseling on menstrual irregularities, delayed return to fertility, and need for condoms for STI protection 1, 8
   • Schedule diabetes follow-up within 2 weeks

2. A1c ≥ 9% OR evidence of vascular complications:

   • Strongly recommend alternative contraception such as copper IUD or progestin IUD, which are highly effective (< 1% failure rate) and safe in all women with diabetes 2
   • If patient insists on DMPA despite counseling, document extensive shared decision-making discussion about increased cardiovascular and metabolic risks 2
   • Arrange urgent diabetes care within 1 week

3. A1c > 12% OR signs of diabetic ketoacidosis:

   • Defer DMPA administration and refer for urgent diabetes management 7
   • Provide interim contraception (condoms, emergency contraception prescription)
   • Reassess DMPA eligibility after diabetes stabilization

Critical Counseling Points Specific to This Patient

Beyond standard DMPA counseling, this patient requires additional diabetes-specific information:

• DMPA may worsen her glucose control, potentially requiring intensification of diabetes medications 5, 3, 4
• She must commit to establishing diabetes care immediately, as uncontrolled diabetes poses greater health risks than unintended pregnancy 7
• Weight monitoring is essential: If she gains > 5% body weight at 6 months, she is at high risk for continued significant weight gain, which will further worsen diabetes control 8
• She should receive calcium 1300 mg daily and vitamin D 600 IU for bone health, as DMPA affects bone density 8, 6

Alternative Contraceptive Options to Discuss

Given her diabetes and financial constraints, long-acting reversible contraceptives (LARCs) may be superior choices 2:

• Copper IUD or progestin IUD: Safe in all women with diabetes, highly effective (< 1% failure rate), no metabolic effects, and cost-effective over time despite higher upfront cost 2
• Progestin implant: Limited data but likely safe, highly effective, and may be covered by insurance with lower long-term cost than quarterly DMPA injections 2

Common Pitfall to Avoid

Do not fail to address the underlying diabetes crisis while focusing solely on contraception. This patient's symptomatic uncontrolled diabetes (polyuria, polydipsia, blurred vision) represents a medical emergency that supersedes routine contraceptive provision. 2, 7 Her statement that she "will establish care" is insufficient—you must facilitate immediate diabetes management through same-day laboratory testing, urgent referral, or direct initiation of diabetes treatment if you are qualified to do so.

Documentation and Follow-Up Plan

Document that you:

• Discussed increased cardiovascular and metabolic risks of DMPA in uncontrolled diabetes 5, 3, 4
• Offered alternative contraceptive methods (IUDs, implant) 2
• Obtained informed consent including diabetes-specific risks if proceeding with DMPA
• Arranged specific diabetes follow-up appointment (not just patient's verbal agreement to "establish care")
• Provided resources for low-cost diabetes care options given her financial constraints

Schedule her next DMPA injection in 11-12 weeks (rather than the full 13 weeks) to allow buffer time for potential missed appointments, which is particularly important given her lack of established care. 8
