What to tell your Doctor before taking Fentanyl

• Your history of a brain tumour or head injury
• Any lung condition or difficulty in breathing
• Whether you have experienced slow beats
• Any kidney or liver condition
• Whether you use any sedative or if you have used an MAO inhibitor recently
• No study has confirmed whether the use of fentanyl is dangerous to pregnant women. You should notify your doctor if you plan to become pregnant or you are pregnant already. It is also not known if the drug passes into breast milk or it could harm a breastfeeding baby.
