Radioactive Iodine Therapy Cost: Procedure, Benefits, and Side Effects
- Radioactive iodine therapy is a widely used treatment in nuclear medicine that targets thyroid cells using radioactive iodine. Doctors commonly use it to treat hyperthyroidism and certain types of thyroid cancer.
- Although the term “radioactive” may sound alarming, the therapy is generally considered safe when administered by trained specialists. It specifically targets thyroid tissue and minimizes exposure to the rest of the body.
- Patients researching treatment options often want to understand both how the therapy works and the cost of radioactive iodine therapy, especially when comparing healthcare services internationally.
- Through MediHelp Global, patients may explore treatment options in advanced medical centers such as Amrita Hospital Faridabad, which offers specialized care for thyroid conditions.
What is radioactive iodine therapy
Radioactive iodine therapy (RAI therapy) is a nuclear medicine treatment that uses radioactive iodine-131 to destroy overactive or cancerous thyroid cells.
The thyroid gland naturally absorbs iodine to produce thyroid hormones. When radioactive iodine is administered, the thyroid absorbs it just like normal iodine.
The radiation then destroys abnormal thyroid cells while leaving most other body tissues unaffected.
RAI therapy is usually given as:
- an oral capsule
- a liquid solution
- occasionally through intravenous administration
Radioactive iodine therapy mechanism of action
The effectiveness of radioactive iodine therapy comes from the thyroid gland’s unique ability to absorb iodine.
After administration:
- Radioactive iodine enters the bloodstream.
- Thyroid cells absorb the iodine.
- Radiation damages and destroys the targeted cells.
Because other tissues do not absorb iodine in the same way, the treatment remains highly focused on thyroid tissue.
This targeted approach makes radioactive iodine therapy an effective treatment for certain thyroid conditions.
Conditions treated with radioactive iodine therapy
Radioactive iodine therapy for hyperthyroidism
Hyperthyroidism occurs when the thyroid gland produces excessive thyroid hormones.
RAI therapy helps reduce hormone production by shrinking the thyroid gland.
It is often recommended when:
- antithyroid medications do not work
- medication side effects occur
- surgery is not suitable for the patient
Radioactive iodine therapy for Graves’ disease
- Graves’ disease is an autoimmune condition that causes an overactive thyroid.
- Radioactive iodine therapy is frequently used to treat Graves’ disease when medication cannot control thyroid hormone levels.
- After treatment, many patients may require lifelong thyroid hormone replacement therapy.
Radioactive iodine therapy for thyroid cancer
- RAI therapy may also be used to treat certain thyroid cancers, particularly papillary and follicular thyroid cancers.
- Doctors may recommend radioactive iodine therapy after surgery to destroy remaining thyroid tissue or cancer cells.
- The therapy can also treat cancer that has spread to lymph nodes or other parts of the body.
How radioactive iodine therapy is performed
The treatment procedure itself is usually simple.
Patients swallow a capsule or liquid containing radioactive iodine.
After ingestion:
- the iodine enters the bloodstream
- the thyroid absorbs the radioactive iodine
- radiation gradually destroys targeted cells
The procedure typically takes only a few minutes, although preparation and follow-up care may require additional time.
Preparation before treatment
Doctors often recommend several preparation steps before radioactive iodine therapy.
These may include:
- blood tests to check thyroid hormone levels
- stopping certain thyroid medications temporarily
- following a low-iodine diet for one to two weeks
- receiving injections to increase thyroid iodine uptake
Patients may also undergo imaging tests to determine how much radioactive iodine the thyroid will absorb.
Recovery and precautions after treatment
Most radioactive iodine leaves the body within several days.
It is primarily eliminated through:
- urine
- sweat
- saliva
- stool
To reduce radiation exposure to others, doctors often recommend temporary precautions such as:
- maintaining distance from others
- avoiding close contact with pregnant women and children
- sleeping separately for several days
- using separate utensils and towels
These precautions usually last between three days and two weeks, depending on the treatment dose.
Iodine therapy side effects
Like most medical treatments, radioactive iodine therapy can cause side effects.
Common radioactive iodine therapy side effects may include:
- neck tenderness
- dry mouth
- taste changes
- swollen salivary glands
- nausea
- fatigue
Some patients develop low thyroid hormone levels after treatment and may need lifelong thyroid hormone replacement medication.
Most side effects are mild and temporary.
Radioactive iodine therapy cost
- The radioactive iodine therapy cost can vary depending on several factors such as location, hospital facilities, and medical requirements.
- Many patients compare the cost of radioactive iodine therapy internationally because treatment prices differ widely between countries.
Factors affecting treatment cost
Key factors influencing the cost include:
- type of thyroid condition being treated
- diagnostic tests and imaging
- hospital stay requirements
- radiation dose used
- follow-up monitoring and medications
Because each patient’s treatment plan is unique, hospitals usually provide a cost estimate after reviewing medical records.
Why patients choose treatment in India
India has become a destination for medical treatment due to:
- experienced specialists in nuclear medicine
- modern medical infrastructure
- internationally accredited hospitals
- comparatively lower treatment costs
Patients from Asia, Africa, and the United States often travel to India for specialized care.
