Frequently Asked Questions about Femara

1. Is Femara chemotherapy?

No, Femara is not a chemotherapy drug even though it treats cancer. It is a type of hormone therapy drug. It reduces the amount of estrogen needed for the development of hormone-dependent cancers. Many people who take Femara are likely to have had chemotherapy or radiotherapy first to fight their cancer.

2. Does Femara work with low AMH?

AMH, or anti-mullerian hormone, is a hormone secreted by ovaries. Testing its levels gives you an indication of the egg reserve. Femara can induce ovulation. But, if the AMH is low, it does not do anything to improve the egg reserve in the body and therefore cannot improve the chances of pregnancy.

3. How many cycles of Femara are safe?

Femara is used to stimulate ovulation in women. There is not a fixed number of cycles. It is most commonly prescribed safely for 6 consecutive cycles. It takes an average time of 3 cycles of Femara or about 90 days to get pregnant. The doctor may tweak the dosage in the case of multiple cycles.

4. Can you take Femara with a cyst?

Hormonal issues in ovulation increase your chances of developing ovarian cysts, which are commonly occurring fluid pockets inside the ovary or on the surface. Yes, you can take Femara with a cyst. It does not cause any side effects, and in fact, the cyst might likely resolve on its own.

5. Does Femara help with low progesterone?

Progesterone is a kind of hormone secreted in the ovaries. Femara does not target the amount of progesterone directly. It increases fertility by reducing estrogen, triggering the body to produce more. However, it can have a similar effect on the progesterone level, as the stimulated eggs are more likely to produce progesterone.

6. Does Femara make your period longer?

Femara shortens a long period by reducing the amount of estrogen. It might increase the amount of bleeding in the first few months due to a change in the level of hormones.

7. How many cycles of Femara to get pregnant?

It varies from person to person and depends on other factors of your case. It takes an average of 3 cycles on Femara, which is around 90 days, to get pregnant. Doctors try to prescribe it anywhere from 3 to 6 cycles. Beyond this, doctors are likely to suggest alternate methods.

8. Has Femara been considered a chemotherapy drug?

No, Femara is not considered a chemotherapy drug. Most chemotherapy drugs treat cancer by working directly on the cancer cells. Femara is a hormone therapy drug that treats breast cancer in post-menopausal women. Hormone therapy uses the growth of specific hormones to inhibit cancer growth.
