Fempro (Letrozole) is used to treat breast cancer in women who are post-menopausal - that is, women who no longer have periods, either naturally due to their age or after surgery or chemotherapy. This medication is available in tablets containing 2.5 mg of the active ingredient, letrozole. Letrozole belongs to a family of medicines called aromatase inhibitors. They are also called "antioestrogens" because they act by reducing the production of oestrogen in your body.
Oestrogen stimulates the growth of certain types of breast cancer. These cancers are called "oestrogen-dependent." Reducing the production of oestrogen may help to keep the cancer from growing.
Dosage and Administration Follow the directions given to you by your doctor and pharmacist carefully.
The usual dose is one Fempro (Letrozole) tablet daily. Swallow the tablet with a glass of water or other liquid. If your stomach is upset after taking the tablet, take it with a meal or after a snack.
Your doctor will check your progress to make sure the medicine is working and will decide how long your treatment should continue.
If you forget to take it: If it is almost time for your next dose (e.g. within 2 or 3 hours), skip the dose you missed and take your next dose when you are meant to. Otherwise, take the dose as soon as you remember, and then go back to taking your tablet as you would normally. Do not take a double dose to make up for the one that you missed.
