Do not eat for 4 hours before a venogram. You may drink only clear fluids for 4 hours before the test.

Before a venogram, tell your doctor if you:

• Are or might be pregnant.
• Are allergic to any medicines, contrast material, or iodine dye.
• Have bleeding problems or take blood-thinning medicines, such as aspirin, heparin, or warfarin (Coumadin).
• Have asthma.
• Have had a severe allergic reaction (anaphylaxis).
• Have had kidney problems.
• Have diabetes, especially if you take metformin (Glucophage).

You will be asked to sign a consent form for this test. Talk to your doctor about any concerns you have regarding the need for the test, its risks, how it will be done, or what the results may mean. To help you understand the importance of this test, fill out the medical test information form(What is a PDF document?).
