Mild and Common Reactions
Some mild side effects may occur during the initial phase of treatment, including:
- Rash and skin itching: The most common side effect, affecting about 5% of patients.
- Nausea and stomach pain: Some people may experience digestive discomfort.
- Headache and dizziness: Caused by the body adjusting to hormonal changes.
- Mild hair loss: Usually temporary and improves as hormone levels stabilize.
2.2. Severe but Rare Side Effects
Although uncommon, some severe side effects may occur, including:
- Agranulocytosis (low white blood cell count): A rare but dangerous side effect (0.2-0.5% of patients) that weakens the immune system, making infections more likely. Symptoms include high fever, persistent sore throat, and unusual fatigue.
- Liver damage: More commonly associated with PTU. Symptoms include jaundice (yellowing of the skin and eyes), dark urine, and prolonged nausea.
- Arthritis and muscle pain: Some individuals may experience joint pain or inflammation due to an autoimmune reaction.
- Vasculitis (blood vessel inflammation): A rare but serious condition that can damage internal organs.
