It's difficult for anyone to be able to say for sure whether a drug is safe to use as it may also depend on your general medical health, any other health conditions you may have and other drugs that are being taken. For this reason, it's best to ring the breast care nurse who has all your medical details to hand and will be able to advise you. Alternatively, a pharmacist at a chemists should also be able to say.
Generally speaking, as far as I can tell, there is not thought to be any interaction, but as I say, it's best to check with your breast care nurse, who can also check with the hospital pharmacist if necessary.
