Letrozole: What It Is and How It Works

Letrozole is a medication that you might have heard about if you’re dealing with breast cancer or struggling with fertility issues. It belongs to a group of drugs called aromatase inhibitors. These drugs work by lowering estrogen levels in the body. Since estrogen can fuel some types of breast cancer, reducing it can slow down or stop cancer growth.

But letrozole isn't just for cancer. Doctors sometimes prescribe it to women facing fertility challenges. By lowering estrogen, it tricks the body into producing more hormones that help with ovulation. This makes it easier to conceive for some women.

What You Should Know About Letrozole Use

When using letrozole, timing and dosage are important. For breast cancer, it’s usually taken once a day over several years to keep estrogen levels low. For fertility, it’s often given for only a few days early in the menstrual cycle to stimulate ovulation. Your doctor will guide you through how and when to take it.

Like any medication, letrozole comes with possible side effects. Some people experience hot flashes, fatigue, or joint pain. If you notice anything unusual or bothersome, it’s a good idea to talk to your healthcare provider rather than just stopping the drug on your own.

Is Letrozole Right for You?

Letrozole is often a key part of treatment plans, but it’s not for everyone. If you are pregnant or breastfeeding, it’s usually avoided because it can harm the baby. Also, your doctor will consider other health factors before prescribing it.
