Brand Cialis 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 Brand Cialis (Tadalafil). The combination is generally fine at 20mg, but a small number of medications can reduce contraceptive efficacy meaningfully and need either a backup method or a switch.
How Brand Cialis 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 Tadalafil acts on CYP3A4 determines whether Brand Cialis affects contraception. Most agents in Erectile Dysfunction (ED) have no clinically meaningful effect on the pill at 20mg.
Practical guidance
According to the prescribing information for Tadalafil, women on hormonal contraception should review Brand Cialis 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 Brand Cialis therapy is the standard mitigation.
Frequently asked questions
Will Brand Cialis make my pill less effective? ▾
Most Erectile Dysfunction (ED) medications at 20mg do not affect oral contraceptive efficacy. The exceptions are CYP3A4-inducing drugs and a small number of others. The prescribing information for Tadalafil states whether the interaction is meaningful.
Do I need a backup contraceptive on Brand Cialis? ▾
Backup contraception is needed only when there is a documented interaction between Brand Cialis and the contraceptive method. For most users at 20mg, no backup is required. The pharmacist confirms whether Tadalafil interacts with hormonal contraception.
