    • barbiturates (for example phenobarbitol)

    • phenybutazone (Butazolidin®)
    • drugs used to treat HIV or AIDS
    • antibiotics
    • phenytoin (Dilantin® is one brand of this drug)

    These medicines/herbal supplements may make your contraceptive less effective and you may need to use a barrier contraceptive when you take these drugs or products.

    Also, tell your healthcare professional if you take lamotrigine (LAMICTAL®), an anticonvulsant used for epilepsy. This may increase the risk of seizures so your healthcare professional may need to adjust the dose
