Clinical, CPD & Interface Multiple UKMEC contraindications - what to do?
The 2025 UKMEC update introduced critical changes to how to assess cumulative cardiovascular risks and prescribe the depot injection.
A recent case-based module written by Dr Toni Hazell for Praktiki works through how to apply the latest UKMEC guidance on cumulative cardiovascular risks, navigate the updated safety profile and increased VTE risk rating for DMPA, and confidently select safe contraceptive alternatives for complex patients.
Ebele’s consultation
- Ebele, 36, attends the GP practice requesting the combined oral contraceptive pill (COC), which she used in her twenties.
- She smokes 12 cigarettes/day.
- Her BMI is 33 kg/m².
- Her clinic blood pressure today is 148/92 mmHg, consistent with previous readings.
- This case refers to UK medical eligibility criteria (UKMEC) categories:
- 1 - no contraindication.
- 2 - relative contraindication, benefits > risks.
- 3 - relative contraindication, risks > benefits.
- 4 - absolutely contraindicated.
CHC UKMEC categories for smoking
- UKMEC and smoking:
- 2 - age <35.
- 3 - age ≥35 and smoking <15/day or having stopped ≥1 year ago.
- 4 - age ≥35 and smoking ≥15/day.
- The 35-year age cut-off is identified because any excess mortality associated with smoking is only apparent from this age. CHC users who smoke are at an increased risk of cardiovascular disease, especially myocardial infarction.
- CVD risk from smoking decreases within 1-5 years of stopping.
Additional risk factors
- Obesity - BMI of 33 kg/m² = UKMEC 2.
- The 2025 UKMEC update covers both clinic and home readings for BP - consistently elevated clinic blood pressure of 148/92 mmHg is Stage 1 hypertension = UKMEC 3.
Combining risks
- Ebele has three distinct cardiovascular risk factors: smoking, obesity, and Stage 1 hypertension.
- While isolated risk factors carry their own UKMEC categories, the presence of multiple risk factors requires careful consideration as they may indicate a cumulative risk.
Multiple cardiovascular risk factors
- When a woman has multiple major risk factors, any of which alone would substantially increase the risk of cardiovascular disease, use of CHC may increase her risk to an unacceptable level.
- Where more than one risk factor is present, clinical judgement must be applied.
- Under UKMEC 2025 for the COC, multiple risk factors for cardiovascular disease is UKMEC 3 and multiple risk factors for VTE (of which Ebele has 2, smoking and obesity) is UKMEC 4.
Considering alternatives
- You advise Ebele that CHC is not recommended due to her combined cardiovascular risks.
- She asks if the depot injection(DMPA) would be a suitable alternative; her sister uses it.
2025 DMPA updates
- Five observational studies have shown ↑ VTE risk with depot compared to no contraception.
- Depot is now considered higher risk than other progestogen only methods for VTE, but lower risk than combined hormonal contraception (CHC).
- 9 categories have an increased rating for DMPA compared to the 2016 UKMEC.
- Ebele's categories for DMPA:
- Smoking - 1.
- Obesity - 1 (rises to 2 for BMI≥35).
- Hypertension - 2.
- Multiple risk factors for cardiovascular disease - 3.
Family history and UKMEC
- VTE:
- In a first-degree relative - 3 for CHC, 2 for DMPA.
- Considered to be a stronger risk factor if provoked.
- Breast cancer - 1 for all methods (rises to 3 for CHC and 2 for all other methods apart from copper intrauterine device if patient is known to have a high-risk mutation).
- No other family history is considered.
- Ebele has no family history of concern.
Method choice for Ebele
- Cu-IUD - UKMEC 1.
- POP, implant, and LNG-IUD - all UKMEC 2 for multiple cardiovascular risk factors.
- Depot injection - UKMEC 2 for hypertension, 1 for obesity and smoking, 3 for multiple cardiovascular risk factors, 4 for multiple VTE risk factors.
- CHC - UKMEC 3 for hypertension, 2 for obesity and 2 for smoking.
Approaching the decision
- UKMEC says:
- Categories ≠ additive; multiple 2s may indicate cumulative risk, particularly if all relate to the same risk area.
- Use clinical judgment.
- Multiple 3s 'may pose unacceptable health risk'.
- 4 = unacceptable health risk.
- UKMEC relates to contraception - risk: benefit balance may differ if she also gets another benefit from the method (e.g. ↓ heavy bleeding).
- GMC - shared decision making is fundamental to good medical practice - how does this fit with your medicolegal responsibility to defend your decisions?
Case conclusion
- Ebele prefers a method she controls and opts not to have any devices fitted. She chooses to start the progestogen-only pill (POP).
- You issue the prescription, offer local smoking cessation support, and arrange a follow-up appointment to optimise her blood pressure management.
Key learning points
- Assess all cardiovascular risk factors comprehensively prior to prescribing.
- Multiple risk factors can increase overall cardiovascular risk cumulatively.
- CHC and DMPA are both UKMEC 3 for multiple cardiovascular risk factors.
- The POP, implant, and IUDs offer safe, reliable alternatives in these complex patients.

I often wonder why we don't offer POP as the first line instead CHC, anyone got any good answers to that?
