As with all medicines there may be potential side effects.
Any side effects should be reported to your pharmacist or GP.
Common side effects include headache, abdominal pain, constipation, diarrhoea, flatulence and nausea/vomiting.
Rare, but serious, signs to be aware of include allergy, reddening of the skin and peeling (potentially Stevens-Johnson syndrome), yellowing skin/dark urine indicating liver problems, bruising/severely reduced general condition and fever (indicating changes in white blood cells).
