Have you read the information leaflet that comes with Letrozole? This describes all fairly clearly. Have you started taking this medication yet or are you having some side-effects?
I am sorry to hear that the Letrozole is making you ill. Can you tell us in what way it is making you ill? This might help us to give you some advice. If you are really having trouble with this drug, please mention it to your specialist nurse or consultant, as there are other drugs that can be prescribed.
