Letrosar-5 Talet belongs to the group of anti-cancer medicines called aromatase inhibitors used to treat breast cancer in women who have gone through menopause (cessation of menses periods). Breast cancer is a type of cancer that develops in breast cells stimulated by the female sex hormone known as estrogen.
 
Letrosar-5 Talet contains 'Letrozole' that works by blocking the aromatase enzyme, which is involved in the production of the estrogen hormone. The cancer cells require estrogen for their growth. Hence, by blocking the aromatase enzyme, Letrosar-5 Talet prevents the growth of cancer cells. Thereby Letrosar-5 Talet helps in preventing or stopping the growth of spreading the tumours (cancer cells) to other body parts.

You are advised to take Letrosar-5 Talet for as long as your doctor has prescribed it for you depending on your medical condition. In some cases, Letrosar-5 Talet may cause certain common side-effects such as hypercholesterolemia (increased cholesterol levels), tiredness, weakness, increased sweating, feeling unwell, pain in joints, and hot flushes (feeling of warmth). Do not be reluctant to talk with your doctor if you experience any of these side-effects persistently.
 
Avoid taking Letrosar-5 Talet if you are pregnant or breastfeeding. Letrosar-5 Talet may cause drowsiness and dizziness, so drive only if you are alert. Letrosar-5 Talet should not be given to children as safety has not been established. Avoid consuming alcohol along with Letrosar-5 Talet as it could lead to increased drowsiness and dizziness. Inform your doctor about your health condition and medications to rule out any side-effects.
