What is the most important information I should know about ambrisentan (Letairis)?

Ambrisentan can harm an unborn baby or cause birth defects. Do not use if you are pregnant.

If you are a woman of child-bearing potential, you will need to have a negative pregnancy test before you start treatment with ambrisentan. You will also be re-tested each month during your treatment.

You will be required to use two forms of birth control to prevent pregnancy during your treatment, and for at least 1 month after your treatment ends. If you have had a tubal ligation or are using a copper IUD, you will not need to use a second form of birth control.

Do not stop taking ambrisentan without first talking to your doctor. You may need to use less and less before you stop the medication completely.

Ambrisentan is available only under a special program called LEAP (Letairis Education and Access Program). You must be registered in the program and sign agreements to use birth control and undergo pregnancy and blood testing as required by the program. Read all program brochures and agreements carefully.
