Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Heart disease: If you have a history of heart disease and have significant thyroid tissue left after thyroid gland removal, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Kidney problems: If you have end-stage kidney disease or are receiving dialysis treatments, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Thyroid cancer patients with metastatic disease: If your thyroid cancer has spread to other parts of the body, especially confined areas (e.g., brain, spinal cord), you may experience local swelling or bleeding at these sites when using thyrotropin alfa.
