UKMEC 2025 · CoSRH

Contraceptive eligibility calculator

A clinical decision-support tool for assessing UK Medical Eligibility Criteria across the main contraceptive methods. Updated to UKMEC 2025 (published December 2025). Enter patient factors on the left; results stream on the right.

Clinical decision support — not a medical device. This calculator summarises UKMEC categories based on the factors you enter. It is not a medical device, does not replace clinical judgement, and does not capture every clinical scenario. Always cross-reference with the full CoSRH guidance and consider initiation vs continuation criteria for individual patients. Where multiple UKMEC 2 or 3 conditions co-exist, cumulative risk may push the overall recommendation higher — apply clinical judgement. Intended for use by qualified UK healthcare professionals.

Patient factors

All fields optional. Leave blank if unknown.

Demographics & vitals

UKMEC 2025 applies NICE classification: home/ABPM thresholds are 5 mmHg lower than clinic readings.

Cardiovascular & thrombotic
Neurological & rheumatological

MS patients have ~1.2x fracture risk; relevant for DMPA. Immobility increases VTE risk.

Endocrine & metabolic
Oncological & hepatic

UKMEC 2025 clarifies "current treatment" includes the years on tamoxifen or aromatase inhibitors, not just primary therapy.

Postpartum & pregnancy
Renal, haematological & HIV (updated 2025)

All severities of CKD increase VTE risk in UKMEC 2025; bone health relevant for DMPA.

UKMEC 2025 uses clinical status and treatment, not CD4 count. Check ART for enzyme interactions separately.

Drug interactions & IUC-specific
