Gastrointestinal Medications with the birth control pill
Many women of reproductive age take a combined or progestogen-only oral contraceptive while also using a chronic medication such as Gastrointestinal Medications (Gastrointestinal Medications). The combination is generally fine at 20mg, 40mg, 10mg, but a small number of medications can reduce contraceptive efficacy meaningfully and need either a backup method or a switch.
How Gastrointestinal Medications can affect contraceptive efficacy
Combined and progestogen-only contraceptives are metabolised through CYP3A4. Strong CYP3A4 inducers (some antiepileptics, rifampicin, St John's Wort) lower contraceptive plasma levels and reduce efficacy. Whether Esomeprazole, Famotidine, Omeprazole, Pantoprazole acts on CYP3A4 determines whether Gastrointestinal Medications affects contraception. Most agents in Gastrointestinal Medications have no clinically meaningful effect on the pill at 20mg, 40mg, 10mg.
Practical guidance
According to the prescribing information for Esomeprazole, Famotidine, Omeprazole, Pantoprazole, women on hormonal contraception should review Gastrointestinal Medications with the prescribing pharmacist or doctor. Where an interaction is documented, additional barrier contraception or switching to a non-oral method (IUD, implant) for the duration of Gastrointestinal Medications therapy is the standard mitigation.
