Sleeplessness is a frequent side-effect and may be reduced by avoiding dosing at bedtime (provided there is at least 8 hours between doses), otherwise your doctor may reduce the dose.
If you have kidney or liver disorders, make sure that you inform your doctor so that he can adjust your dose, if necessary.
If you forget to take DIRENTO SR 150 mg: Do not take a double dose to make up for forgotten individual doses. If you missed a dose, take it as soon as possible.
