Q and A


Are there interactions between TLD and levonorgestrel?

I’m on TLD drugs and i took a levonorgestrel tablet, should i be worried about the efficacy of the levonorgestrel drug or interaction of the two pills?


Hi there

There are no interactions between any of the meds in TLD and any formulation of levonorgestrel – whether for for HRT, emergency contraception, implants etc.

The best drug interaction website is this site from the University of Liverpool:

This is a link to the report from the Liverpool website showing no interactions:
