What are symptoms of agranulocytosis?
Having very low levels of granulocytes in the blood can lead to serious or life-threatening infections. Signs and symptoms of agranulocytosis include fever, chills, weakness, sore throat, sores in the mouth or throat, bleeding gums, bone pain, low blood pressure, fast heartbeat, and trouble breathing.
How does carbimazole cause agranulocytosis?
Carbimazole-induced agranulocytosis occurs generally within few weeks or months of taking the anti-thyroid medication, but onset may be delayed by 1 year with an incidence of 0.1%–0.3%. Agranulocytosis is a serious rare side effect of carbimazole….

Why does propylthiouracil cause agranulocytosis?
Immune mechanisms also seem to have a role in pathogenesis, as previously documented with positive lymphocyte transformation tests [16]. Circulating antibodies against differentiated granulocytes may be responsible for propylthiouracil-induced agranulocytosis, rendering this process immune mediated [17].
What are the adverse effects of propylthiouracil?
Propylthiouracil may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
- hair loss.
- difficulty tasting food.
- numbness, burning, or tingling of the hands or feet.
- joint or muscle pain.
- dizziness.
- swelling of the neck.
What happens when granulocytes are low?
Low granulocytes is a condition called granulocytopenia, or sometimes called agranulocytosis. A low granulocytes count is usually caused by a condition affecting the blood such as anemia or leukemia. Such conditions either stop the body from being able to produce new blood cells, or damages existing blood cells.
Does methimazole cause agranulocytosis?
Agranulocytosis is a rare and serious adverse effect of antithyroid drugs (ATD), in particular methimazole (MMI), and usually develops within 3 months following the start of uninterrupted ATD treatment.
What are the side effects of methimazole?
Common side effects may include:
- nausea, vomiting, upset stomach;
- headache, dizziness, drowsiness;
- numbness or tingly feeling;
- rash, itching, skin discoloration;
- muscle or joint pain;
- hair loss; or.
- decreased sense of taste.
Does propylthiouracil cause agranulocytosis?
Background: Propylthiouracil (PTU) has been in use for more than half a century for the treatment of hyperthyroidism. While it is largely known to cause agranulocytosis, its association with aplastic anemia is generally unheard of.
How is agranulocytosis diagnosed?
To diagnose agranulocytosis, your provider will order a blood test. This test, called a complete blood count (CBC), checks neutrophil levels in your blood. Your healthcare provider may also take a sample of your bone marrow to evaluate how your body produces white blood cells.
Can propylthiouracil cause sore throat?
Get emergency medical help if you have signs of an allergic reaction (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).
How is low granulocytes treated?
A treatment called granulocyte colony-stimulating factor (G-CSF). This stimulates the bone marrow to produce more white blood cells. It is used for several types of neutropenia, including low white cell count from chemotherapy. This treatment can be lifesaving in these cases.
