How you have Letrozol
You take Letrozol as a tablet, once a day. It is best to take the tablets at the same time each day. You can take them with or without food.
It is very important that you take tablets according to the instructions your doctor or pharmacist gave you. You should take the right dose, not more or less. And never stop taking a cancer drug without talking to your specialist first.
If you accidentally take too much Femara, contact a doctor or hospital straight away. You may need medical treatment.
If you forget to take a dose and it is almost time for your next dose (for example, within 2 or 3 hours), skip the dose you missed and take your next dose when it is due. Otherwise, take the dose as soon as you remember, and then take the next dose at the normal time. Don't take a double dose.
