FAQs

Why have I been prescribed Oncolet 2.5mg Tablet?

Oncolet 2.5mg 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.

How does Oncolet 2.5mg Tablet work?

Oncolet 2.5mg 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.

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 Oncolet 2.5mg Tablet till the tumor shows progression. In cases where Oncolet 2.5mg 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.
