Iodotope

1 What is Iodotope?

Brand: Iodotope

Generic: Radiopharmaceutical

Iodotope is substance or agent used by doctors to diagnose or treat medical conditions. Radiopharmaceuticals are radioactive, but they emit very small amounts of radiation that makes them safe to the body.

Radiopharmaceuticals spread throughout the tissue sometime after administration. The tiny amount of radiation is detected by imaging devices and works to make the organ or tissue more visible to imaging. This help doctors see the organ or tissue much more clearly to diagnose the presence of tumors, blockages, abscess, swelling or other abnormalities.

At larger doses, Radiopharmaceutical is used to treat diseases like cancer.

Radiopharmaceuticals can be taken by mouth, injected into the veins or even placed in the eye or bladder.

Certain Radiopharmaceuticals, such as OncoScint(R) CR/CV (satumomab pendetide) and NeutroSpec (technetium 99m TC fanolesomab), was discontinued in the United States due to high risk of severe side effects.

Radiopharmaceuticals require a prescription according to doctor’s instructions.

Only doctors specializing in a field of science called Nuclear Medicine can prescribe and treat using Radiopharmaceuticals.

2 What to know before using

Before using Iodotope, you must know all about the risks and complications associated with it.

Tell the doctor if you experienced sensitivities or allergies to certain Radiopharmaceuticals.

Certain Radiopharmaceuticals can be used to children and elderly, though they may need monitoring or additional lab tests.

Tell your doctor if you are pregnant or breastfeeding before taking Radiopharmaceuticals.

Radiopharmaceuticals emit radiation can harm unborn babies in pregnant patients. If you are female and of reproductive age, the doctor may order a pregnancy test before your receive Radiopharmaceuticals to ensure you are not pregnant.

Make sure you tell all the medications you take before taking Radiopharmaceuticals.

3 Proper usage

To use Iodotope properly, you must follow all instructions given by your doctor.

Radiopharmaceuticals require special steps in preparation and administration. The doctor will tell you in advance on to do before the test.

Depending on the procedure, you may have to fast hours before the test, or drink plenty of fluids or have enemas or laxatives after that.

For accurate results and low chances of adverse effects, make sure you follow the instructions well.

Call the doctor if you need help in understanding the instructions.

4 Precautions to take

Before using Iodotope, there are some precautions you must take.

The amount of Radiopharmaceuticals used in diagnosis is usually very small, so no special precautions are necessary.

In many tests, doctors will recommend you to take plenty of fluids after the test. Many Radiopharmaceuticals are eliminated in the kidneys, and drinking more fluids help flush them out.

Call your doctor if you became

  • dehydrated,
  • have fever,
  • vomiting,
  • have reduced or zero urine output.

Certain Radiopharmaceuticals can alter lab results. For example, radioactive iodine may alter future thyroid tests.

If you receive care from another doctor or will have lab tests, make sure they know you received Radiopharmaceuticals.

5 Potential side effects

As with many medications, there are several potential side effects associated with Iodotope.

The amount of Radiopharmaceuticals used in diagnosis is very small, so adverse effects are unlikely. If they do occur, an allergic reaction is usually the most common.

Call your doctor if you experienced the following:

  • Allergic reaction symptoms such as a rash, hives, itching, swelling of the lips, tongue or throat
  • Fever
  • Chills
  • Difficulty breathing
  • Severe drowsiness
  • Fast heart rate
  • Flushing or redness of skin
  • Nausea or vomiting
  • Stomach pain
  • Swelling of the hands or feet
