Drug Information
4 reviews for Letrozole (Femara)
Femara contains Letrozole.
Letrozole is a hormone medicine used to treat breast cancer in women after menopause. It is also used by fertility specialists to help women ovulate (release an egg).
What is it used for?
- Early and advanced breast cancer (hormone receptor-positive)
- Helping ovulation in some women with fertility problems (off-label)
How does it work?
Letrozole blocks the aromatase enzyme, which lowers oestrogen levels. For fertility, a short course causes the brain to release more hormones that trigger ovulation.
This information is written in simple words to help you understand this product. It does not replace advice from your doctor or pharmacist.
Read these points before you start. If any of them apply to you, talk to your doctor or pharmacist first.
- It is only for women who have been through menopause (or whose ovaries have been switched off).
- It can thin the bones. Your doctor may check your bone density and suggest calcium, vitamin D or bone medicines.
- Do not take it with oestrogen or HRT, as these reduce its effect.
- Tell your doctor if you have liver or kidney problems or osteoporosis.
- For fertility use, follow your specialist's plan exactly. It is usually taken for only 5 days per cycle.
- Tell your doctor or pharmacist about every other medicine, vitamin or herbal product you use.
- Keep this product out of the reach and sight of children.
Like all medicines, Femara can cause side effects, but not everybody gets them.
Common side effects
- Hot flushes
- Joint pain and stiffness
- Tiredness
- Headache
- Hair thinning
- Vaginal dryness
These are usually mild and often get better as your body gets used to it. Tell your doctor if they bother you or do not go away.
Stop using it and get medical help straight away if you notice:
- Signs of a severe allergic reaction
- Yellowing of the skin or eyes
- Chest pain or signs of a heart problem
This is not a complete list. If you notice anything unusual, ask your doctor or pharmacist.
- For breast cancer: take one 2.5 mg tablet once a day, at the same time each day.
- For fertility: take it for 5 days early in your cycle, as your specialist tells you.
- Swallow the tablet with water, with or without food.
If you miss a dose: Take it as soon as you remember, unless it is nearly time for your next dose. Never take two doses at once.
If you use too much: Contact your doctor, a poison control centre or your local emergency number straight away, even if you feel fine. Take the pack with you.
How to store it: Keep it in its original pack at room temperature (below 25°C / 77°F), away from heat, damp and direct sunlight. Do not use it after the expiry date.
