Important Safety Information
What is the most important information I should know about Letairis?
Letairis can cause serious birth defects if taken during pregnancy.
- Females must not be pregnant when they start taking Letairis or become pregnant while taking Letairis.
Females who are able to get pregnant must have a negative pregnancy test before beginning Letairis, each month during treatment, and one month after stopping Letairis. Your doctor will decide when to do the tests, and order the tests for you depending on your menstrual cycle.
Females who are able to get pregnant are women who:
- Have entered puberty (even if they have not started their period), and have a uterus, and have not gone through menopause (have not had a period for at least 12 months for natural reasons, or who have had their ovaries removed)
- Females who are able to get pregnant are women who:
Females who are able to get pregnant must use two acceptable forms of birth control, while taking Letairis and for one month after stopping Letairis because the medication may still be in the body.
- If you have had a tubal sterilization or have an IUD or progesterone implant, these methods can be used alone and no other form of birth control is needed.
- Talk with your doctor or gynecologist to find out about options for acceptable forms of birth control that you may use to prevent pregnancy during treatment with Letairis.
- If you decide that you want to change the form of birth control, talk with your doctor to be sure that you choose another acceptable form of birth control.
- Do not have unprotected sex. Talk to your doctor or pharmacist right away if you have unprotected sex or if you think your birth control has failed. Your doctor may tell you to use emergency birth control.
- Tell your doctor right away if you miss a menstrual period or think you may be pregnant.
If you are the parent or caregiver of a female child who started taking Letairis before reaching puberty, you should check your child regularly to see if she is developing signs of puberty. Tell your doctor right away if you notice that she is developing breast buds or any pubic hair. Your child may reach puberty before having her first menstrual period.
