Radioactive iodine is a type of nuclear medicine treatment that's often used to treat some types of thyroid problems, such as selected thyroid cancer patients and people with hyperthyroidism. Treatment consists of a radioactive medication called radioactive iodine. Radioactive iodine remains in the body for a time after treatment, so the patient might need to take additional precautions for a period of time after treatment. These are the precautions that are mostly to reduce unnecessary radiation exposure to other people, particularly family members, children, pregnant women, caregivers, and people around you.
Precautions and durations depend upon radioactive iodine dosage, condition treated, patient health, and treatment protocol. Molecular Diagnostics and Therapy is a unit that enables patients to receive help with preparation for nuclear medicine treatment and post-treatment care. Dr. Nikunj Jain, Co-Founder, HOD – Nuclear Medicine, provides counseling to patients during the treatment planning phase and after treatment, as well as follow-up depending on the patients' requirements.
Why Are Precautions Needed After Radioactive Iodine Treatment?
Once radioactive iodine has been administered, it is slowly secreted through the urine, saliva, sweat, and various body fluids. During this time, the patient's body gives off low-level radiation. The quantities of radiation decline with time; however, close and/or longer contact with others may need to be restricted for a period of time. By closely following the directions you have been given by your nuclear medicine staff, you're reducing unnecessary radiation exposure and are giving your treatment the best chance of success. Precautions are temporary and may vary according to the dosage and the treatment.
Maintain Distance From Other People
The most crucial thing after radioactive iodine therapy is limiting your close and prolonged contact with other people. You might need to:
Maintain a reasonable distance from others when possible
Avoid prolonged face-to-face contact
Spend less time in close physical contact with family members
Avoid unnecessary visits to crowded places
Follow additional restrictions if advised by your nuclear medicine team
Take Special Care Around Children and Pregnant Women
Fetuses and children are more susceptible to radiation exposure. Moreover, extra safety measures might be required for children and pregnant women. Your doctor might ask you not to come in contact with them for an extended period of time. Instructions for your return home should be discussed among all treatment providers if you have a child or a person who is pregnant. The precautions are particularly important after radioactive iodine therapy, especially high doses of radioactive iodine.
Sleep Separately When Advised
Sleeping in a separate bed from other individuals for some time may be recommended post-treatment. This has the effect of reducing the duration of close contact with another when asleep. The length of time spent in separation varies based on the type of treatment and recommendations from your healthcare team. If you share a room with somebody else, ask your nuclear medicine specialist if there are any other precautions that you should take. Follow Good Hygiene Practices Good personal hygiene can help reduce the spread of radioactive iodine through body fluids. Patients are generally advised to:
Wash their hands thoroughly and frequently
Take regular showers if instructed
Keep the bathroom clean
Flush the toilet twice after each use.
Wash clothing and personal items as instructed
Avoid sharing personal hygiene items
If your medical team provides specific instructions regarding bathroom use or cleaning, follow those instructions carefully. Drink Plenty of Fluids Our body discharges radioactive iodine through urine, but taking more liquids speeds up the elimination. If the patient drinks a lot of water or any other fluids, then it helps the body to flush radioactive iodine. So, according to doctors, It is advisable to drink more water, especially during the first few days after treatment. If the patient has certain medical conditions, the doctor may advise restrictions on fluid intake.
Use Separate Personal Items When Recommended Your medical team will tell you how long to avoid sharing certain items, and you may not be allowed to share some of the items for a time. These might include towels, toothbrushes, feeding utensils, or anything that may come into contact with saliva or other bodily fluids. Do as your treatment centre advises; some of their recommendations might differ depending on the radioactive iodine dose.
Be Careful When Travelling Extra planning might need to occur when it comes to traveling after receiving radioactive iodine. Radioactive iodine is sometimes found at airport/security screenings or elsewhere after you leave the treatment centre via radiation monitoring. (Always bring your nuclear medicine treatment certificate or paperwork with you when travelling.) Make sure you also inform your doctor of any travel precautions while traveling and ask your doctor about any travel precautions or concerns.
Follow Workplace and Public Contact Instructions Sometimes, there are temporary restrictions on your job depending on the Iodine-131 therapy. People working with children, pregnant women, or people who are in close contact with many others could require specific directions. Similarly, individuals with close working relationships with others for long periods, such as healthcare, schools, childcare, and the like, may need additional steps taken. Return-to-work advice is to do so when advised by your Medical Team, depending on the treatment dose and your occupation.
Role of Molecular Diagnostics and Therapy Molecular Diagnostics and Therapy are offered for diagnostic and nuclear medicine purposes and are related to evaluation and management of thyroid disorders. Depending on the individual, appropriate thyroid blood tests, imaging, and nuclear medicine investigations may assist doctors in monitoring patients prior to and following radioactive iodine treatment. Dr. Nikunj Jain, Co-Founder and HOD, helps patients plan for radioactive iodine and then talks about precautions and follow-up after this treatment. There are some suggestions that are based on the patient's treatment dose, diagnosis, and clinical situation.
Conclusion After radioactive iodine therapy, taking precautions is a good idea for minimising unnecessary radiation exposure to those around you. Keeping a normal distance from others, being careful near children and pregnant women, observing hygiene precautions, drinking enough fluid - safely, as appropriate for medical reasons, and following travel and workplace precautions can all help to promote safe healing. These precautions only last for a temporary period of time and may last longer or shorter for different individuals. Always follow the specific instructions from your nuclear medicine specialist rather than general advice from other sources.
Under the supervision of Dr. Nikunj Jain, Molecular Diagnostics and Therapy delivers services for nuclear medicine and diagnostics for patients and their families throughout the process of evaluation, treatment, and follow-up. Radioactive iodine therapy can be performed safely and effectively when patients follow the post-treatment instructions given by their medical team.
