Before taking this medicine
You should not use torsemide if you are allergic to it, or if:
you are unable to urinate; or
you are allergic to an oral diabetes medicine.
Tell your doctor if you have ever had:
heart disease;
kidney problems (unless you are taking torsemide for edema related to kidney disease);
liver problems such as cirrhosis or hepatitis (unless you are taking torsemide for edema related to liver disease);
gout;
an allergy to povidone (sometimes contained in iodine, Betadine); or
if you are on a low-salt diet.
If you need to have any type of x-ray or CT scan using a dye that is injected into your veins, tell your caregivers that you currently take torsemide.
Tell your doctor if you are pregnant or plan to become pregnant. It is not known whether torsemide will harm an unborn baby. However, having high blood pressure during pregnancy may cause complications such as diabetes or eclampsia (dangerously high blood pressure that can lead to medical problems in both mother and baby). The benefit of treating hypertension may outweigh any risks to the baby.
It may not be safe to breastfeed while using this medicine. Ask your doctor about any risk.
Torsemide is not approved for use by anyone younger than 18 years old.
