Letrozole

Letrozole quietly lowers estrogen in the body, which can help certain hormone-sensitive concerns—like supporting ovulation or managing some breast health plans. It’s not a one-size-fits-all fix, but many people find it useful when a doctor feels it fits their needs. Think of it as a gentle nudge to your hormones, not a full reset.

• Usually taken as a small tablet once a day, around the same time.
• Common side effects may include tiredness, warm flashes, or mild aches; tell your doctor if anything feels off.
• Avoid if you’re pregnant or could become pregnant, and share all other medicines with your care team.
• Skip heavy alcohol, and check with your clinician before starting new supplements.
