How Letrozol works
Letrozol is an aromatase inhibitor. It works by decreasing the amount of estrogen (natural female hormone) produced in the body. This decrease in estrogen can slow down or stop the growth of some breast cancers that need estrogen to grow. In addition, it is also useful in infertility whereby it increases the release of certain hormones to stimulate the release of eggs from the ovaries.
What if you forget to take Letrozol?
If you miss a dose of Letrozol, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular schedule. Do not double the dose.
