Antithyroid drugs are essential in managing hyperthyroidism and Graves’ disease. Quickly recalling their indications and side effects can improve clinical decision-making and patient care. Below are memory aids designed to help students and healthcare professionals remember key points about these medications.
Common Antithyroid Drugs
- Propylthiouracil (PTU)
- Methimazole (MMI)
- Carbimazole (prodrug of MMI)
Memory Aid for Indications
Think “GAPS”: Graves, Autoimmune, Pregnancy, Short-term
- Graves’ disease
- Autoimmune hyperthyroidism
- Pregnancy (especially PTU in first trimester)
- Short-term therapy before surgery or radioactive iodine
Memory Aid for Side Effects
“FAT CARS”: Fever, Agranulocytosis, Toxic hepatitis, Cardiotoxicity, Arthralgia, Rash, Stevens-Johnson syndrome
- Fever and sore throat (sign of agranulocytosis)
- Agranulocytosis (dangerous decrease in white blood cells)
- Toxic hepatitis (liver toxicity)
- Cardiotoxicity (e.g., arrhythmias)
- Arthralgia (joint pain)
- Rash and Stevens-Johnson syndrome (severe skin reactions)
Additional Tips for Remembering
Use mnemonics like “GAPS” for indications and “FAT CARS” for side effects. Remember that PTU is preferred in pregnancy early on, but MMI is more commonly used otherwise. Always monitor liver function and blood counts during therapy.

Indications: GAPS
Side Effects: FAT CARS
These memory aids simplify the complex pharmacology of antithyroid drugs, making it easier for students and clinicians to recall critical information quickly.
