Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Experimental Arm (Artificial Tears)
Participants in this arm will receive artificial tears to be administered in the 4 days immediately following radioactive iodine therapy. The schedule of administration will be as follows: Day 1 (day of radioactive iodine therapy): Every 15 minutes for 2 hours, then every 30 minutes for at least 4 hours or until bedtime at night Day 2: Once every 1 hour for 12 hours Day 3: Four times (approximately morning, lunch, dinner, and evening) Day 4: Two times (morning and evening) |
Participants will self-administer the artificial tears according to the schedule.
|
No Intervention: No Intervention (No Artificial Tears)
Participants in this arm will not administer artificial tears in the 4 days immediately following radioactive iodine therapy.
