4. possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.

- Fever, joint swelling and pain, muscle aches, blood in urine, shortness of breath, rash.
Propylthiouracil may cause the increase of a particular type of antibody “ANCA” (anti-neutrophil cytoplasmic antibodies) and inflammation of the walls of blood vessels which can be serious if not treated. This can occur even if you have been taking propylthiouracil for many years.

- Itching;
- Hair loss;
- Skin colourations;
- Swelling (for example in the legs and feet);

- Kidney inflammation (blood in the urine), bruises and blood spots due to inflammation of the small blood vessels in the skin, breathlessness and cough;
- Slow blood clotting, bleeding and bruising more easily than usual.
Not known (frequency cannot be estimated from the available data): Liver failure, liver inflammation.
If you feel unwell in any other way, tell your doctor as soon as you can.
