Overview

Letrotas 2.5mg Tablet is a prescription-only medicine (POM) presented as a tablet, with Letrozole 2.5mg as its active ingredient content.

This page is limited to product, safety and handling information, in line with Malaysian rules on prescription medicine information for the public. Your prescriber or pharmacist is the right source for anything beyond that, together with the leaflet inside the pack.

Through DoctorOnCall, this product is supplied after an online consultation with a licensed doctor and a valid prescription, and it is checked by a registered pharmacist before dispensing. Take it exactly as prescribed, and speak to your doctor before stopping, changing the dose, or starting any other medicine alongside it.

Directions for Use

Take Letrotas 2.5mg Tablet once daily, at about the same time each day, with or without food. Swallow the tablet whole with a glass of water. Continue taking this medicine for the full duration prescribed by your specialist, even if you feel well, as breast cancer hormonal therapy requires consistent long-term use.

Dosage

The usual dose of Letrotas 2.5mg Tablet for breast cancer treatment is 2.5mg taken once daily, continued for the duration determined by your oncologist based on your specific cancer stage and treatment plan. Never adjust the dose or stop treatment without consulting your specialist, as this is a long-term hormonal therapy that requires consistent use for full benefit.

Drug / Food Interactions
