Like all medicines, Zopya can cause side effects, although not everybody gets them.
Contact your doctor immediately if you experience:
- fever, signs of infection or extreme tiredness. These may be due to rare decrease of some blood cells.
- signs of liver problems such as yellowing of the skin and/or the eyes (jaundice), whether or not associated with bleeding which appears under the skin as red pinpoint dots and/or confusion (see ?Take special care with Zopya?).
- swelling in the mouth or skin disorders such as rashes and itching, blisters of the skin. These may be the signs of an allergic reaction.
The most common side effect (affects 1 to 10 patients in 100) is bleeding.
Bleeding may occur as bleeding in the stomach or bowels, bruising, haematoma (unusual bleeding or bruising under the skin), nose bleed, blood in the urine. In a small number of cases, bleeding in the eye, inside the head, the lung or the joints has also been reported.
If you experience prolonged bleeding when taking Zopya
If you cut or injure yourself, it may take slightly longer than usual for bleeding to stop. This is linked to the way your medicine works as it prevents the ability of blood clots to form. For minor cuts and injuries e.g., cutting yourself, shaving, this is of no concern. However, if you are concerned by your bleeding, you should contact your doctor straightaway (see ?Take special care with Zopya?).
