In Treatment of Breast cancer

Letrocres Tablet relieves the symptoms of breast cancer such as breast lumps, bloody discharge from the nipple, or changes in the shape or texture of the breast. It works by altering the production of those hormones in the body that are essential for the growth and spread of breast cancer. It may also interact with other hormones or have a direct effect on cancer to stop its growth.

In Treatment of Infertility due to anovulation

Letrocres Tablet helps in the normal development of an egg in a woman's ovary (female reproductive organ) and stimulates the release of the egg during a process called ovulation. This helps to treat infertility in women. This increases the chance of a successful pregnancy. You should use the medicine as prescribed for it to be effective.

Q. Why have I been prescribed Letrocres Tablet?

Letrocres Tablet is an aromatase inhibitor. It is generally prescribed to treat breast cancer in women who no longer have periods, either due to menopause or after surgery or chemotherapy. It is also used to treat infertility caused due to anovulation (during menstrual cycle egg cell from ovaries is not released).

Q. How does Letrocres Tablet work?

Letrocres Tablet is also known as an anti-estrogen drug. It is called so because it acts by reducing the production of estrogen in your body by blocking the enzyme aromatase, which is responsible for the production of estrogen. Estrogen stimulates the production of certain types of breast cancer in your body. These cancers are called "estrogen-dependent cancers". Reducing the production of estrogen may prevent cancer from growing.

Q. For how long should I take Letrocres Tablet?

If the breast tumor is in the advanced stage or has spread to other parts of the body, it is recommended that you continue taking Letrocres Tablet till the tumor shows progression. In cases where Letrocres Tablet is given after tamoxifen (another anti-estrogen used for breast cancer) or surgery, it should be given for 5 years or until the tumor comes back, whichever is first. It can also be given as a sequential treatment; 2 years of Letrocres Tablet followed by 3 years of tamoxifen.

Although it is very uncommon, Letrocres Tablet may cause a cataract. So, if you experience blurred vision or eye irritation, consult your doctor immediately.

Q. My friend who is taking Letrocres Tablet often sweats a lot. Is it because of Letrocres Tablet?

However, in some people, the flushes and sweats may continue during the treatment and stop a few months after the treatment finishes. You can consult your doctor who will provide you a remedy if it is very bothersome.
