What it is

How to use

• AM — Take the prescribed dose with water or as instructed by your clinician. Record the dose and time to maintain consistent dosing.
• PM — If a split dose is recommended, follow your prescriber’s schedule and avoid doubling doses to catch up.
• The liquid form can be measured in small increments to match a clinician’s recommended dose. Do not change or stop treatment without consulting a healthcare provider.

Why it works

• Letrozole (active) — Inhibits the aromatase enzyme, which reduces conversion of androgens into oestrogens.
• Oral liquid formulation — Enables precise dose adjustments compared with whole tablets.
• Convenience — Single bottle provides a measured supply and a dropper for controlled administration.

What to expect

• Hormone-related effects can begin to appear within days, but individual response varies; some systemic effects may take longer to be noticeable.
• Letrozole has a half-life measured in days; discuss monitoring frequency and follow-up testing with your prescriber.

Good to know

• Commonly reported side effects include joint pain or stiffness, hot flashes, fatigue, headache, nausea and mood changes. Long-term use may affect bone density.
• Do not use if pregnant or breastfeeding. Avoid use in children. Always confirm suitability with a healthcare professional before starting.
• Letrozole can interact with other medicines (for example, some breast cancer treatments, oestrogen-containing therapies and certain blood thinners). Tell your prescriber about all medicines, supplements and medical conditions.
