DRUG INTERACTIONS

Jadelle® (levonorgestrel implants (unavailable in us)) implants are not recommended for women who require chronic use of phenytoin, phenobarbital, carbamazepine or oxcarbazepine because Jadelle® (levonorgestrel implants (unavailable in us)) is likely to be less effective for these women. Although the large clinical trials of NORPLANT® and of Jadelle® (levonorgestrel implants (unavailable in us)) implants excluded women with epilepsy, there are published studies showing decreased levonorgestrel concentrations in women taking these antiepileptic drugs along with levonorgestrel-containing contraceptives. These drugs may increase the metabolism of levonorgestrel through induction of microsomal liver enzymes. For women receiving long-term therapy with hepatic enzyme inducers, a different method of contraception should be considered. Women on short-term therapy with hepatic enzyme inducers should consider using a back-up method of contraception (such as condoms or spermicides) for the duration of therapy.

Rifampicin is known to decrease the effectiveness of combination oral contraceptives; its effect on levonorgestrel concentrations has not been established. Data from clinical trials of NORPLANT® implants, however, indicate low serum concentrations and subsequent pregnancy in one woman using rifampicin.

Herbal products containing St. John's Wort (hypericum perforatum) may induce hepatic enzymes (cytochrome P450) and may reduce the effectiveness of contraceptive steroids.

Laboratory Test Interactions

Certain endocrine tests may be affected by Jadelle® (levonorgestrel implants (unavailable in us)) use:

  1. SHBG concentrations are decreased.
  2. Thyroxine concentrations may be slightly decreased and triiodothyronine uptake increased.
