(unless otherwise stated)
|Rationale for decision / comments|
|Women requiring contraception should be given information about and offered a choice of all methods including LARC (long-acting reversible contraception).|
The effectiveness of combined oral contraceptives, progestogen-only oral contraceptives, contraceptive patches, and vaginal rings can be considerably reduced by interaction with drugs that induce hepatic enzyme activity (e.g. carbamazepine, eslicarbazepine, modafinil, nelfinavir, nevirapine, oxcarbazepine, phenytoin, phenobarbital, primidone, ritonavir, St John’s Wort, topiramate, and, above all, rifabutin and rifampicin).
Hormonal contraceptives and antibacterials that do not induce liver enzymes
Advice on interactions between combined hormonal contraceptives and antibacterials that do not induce liver enzymes has been updated to take into account the recommendations of the Faculty of Sexual and Reproductive Healthcare Clinical Guidance: Drug Interactions with Hormonal Contraception (January 2011).
Additional contraceptive precautions are no longer necessary when antibacterials that do not induce liver enzymes are taken with combined oral contraceptives, (unless diarrhoea or vomiting occurs), contraceptive patches or vaginal rings. Click here for more information.

Pregnancy should be excluded before ulipristal is taken.
EllaOne is excluded from the MHRA alert affecting ulipristal for uterine fibroid treatment
|Please note that patients who have a BMI >26 or are greater than 70kg may require more than the standard 1.5mg dose of levonorgestrel.
Consider double dose (3mg) or CI-IUD or ulipristal.Link
Women taking enzyme inducing medication may require further measures. EC providers should advise women using enzyme-inducing drugs that the
effectiveness of UPA-EC and LNG-EC could be reduced.
Women requiring EC who are using enzyme-inducing drugs should be offered a Cu-IUD if appropriate. A 3 mg dose of LNG can be considered but women should
be informed that the effectiveness of this regimen is unknown. A double-dose of UPA-EC is not recommended.
