ORELOX can have side effects. Not all side effects reported for ORELOX are included in this leaflet. Should your general health worsen or if you experience any untoward effects while receiving ORELOX, please consult your doctor, pharmacist or other healthcare provider for advice.
If any of the following happens, stop taking ORELOX and tell your doctor immediately or go to the casualty department at your nearest hospital:
- you have an allergic reaction. The signs may include: a rash, joint pain, swallowing or breathing problems, swelling of your lips, face, throat or tongue
- blistering or bleeding of the skin around the lips, eyes, mouth, nose and genitals. Also flu-like symptoms and fever. This may be a severe skin allergy, called Stevens-Johnson syndrome
- severe blistering rash where layers of the skin may peel off to leave large areas of raw exposed skin over the body. Also, a feeling of being generally unwell, fever, chills and aching muscles. This may be something called toxic epidermal necrolysis
- widespread rash, high body temperature and enlarged lymph nodes (DRESS syndrome or drug hypersensitivity syndrome)
- a red, scaly widespread rash with bumps under the skin and blisters accompanied by fever. The symptoms usually appear at the initiation of treatment (acute generalised exanthematous pustulosis)
- you have a skin rash or skin lesions with a pink/red ring and a pale centre which may be itchy, scaly or filled with fluid. The rash may appear especially on the palms or soles of your feet. These could be signs of a serious skin allergy called erythema multiforme
- chest pain in the context of allergic reactions, which may be a symptom of allergy triggered cardiac infarction (Kounis syndrome)
- rash with blisters arranged in a circle with central crusting or like a string of pearls (linear IgA disease)
- you get infections more easily than usual. This could be because of a blood disorder. This is more likely if you are taking ORELOX for a long time
- a severe infection of the lining of the bowel, characterised by diarrhoea, fever and abdominal pain. This may be something called pseudomembranous colitis
- yellowing of the skin, eyes or mouth and feeling tired. You may also be more pale than normal. This could be because of a serious type of anaemia.
These are all very serious side effects. If you have them, you may have had a serious allergic reaction to ORELOX. You may need urgent medical attention or hospitalisation.
Tell your doctor immediately or go to the casualty department at your nearest hospital if you notice any of the following:
- superinfection (a second infection which occurs during the course of the existing infection, by other bacteria or organisms resistant to ORELOX), including fungal infections such as oral or vaginal thrush
- severe diarrhoea
- Serious neurological problems known as encephalopathy: seizures, confusion, consciousness disorders or even abnormal movements, particularly in case of overdose or renal impairment (see sections 2 and 3)
These are all serious side effects. You may need urgent medical attention.

- nausea (feeling sick) or vomiting (being sick)
- stomach pains
- headaches
- feeling dizzy
- paraesthesia (pins and needles; numbness or tingling feelings)
- tinnitus (ringing in the ears)
