For women with a history of venous thromboembolic disease, combined hormonal contraception (CHC), which includes the pill, transdermal patch, or vaginal ring, should not be used due to an unacceptable health risk (UKMEC 4) NICE CKS.
The UK Medical Eligibility Criteria for Contraceptive Use (UKMEC) provides guidance on combined hormonal contraception, progestogen-only contraception, and intrauterine contraception for women with specific medical conditions NICE CKS. While CHC is contraindicated, other hormonal and intrauterine methods of contraception can generally be considered NICE CKS. UKMEC Category 1 indicates no restriction for use, and UKMEC Category 2 means the method can generally be used, with advantages typically outweighing theoretical or proven risks, though more careful follow-up may be required NICE CKS.
