Zaldiar is a tablet that contains 37.5 mg Tramadol and 325 mg Paracetamol. A lower dose can be given to those with liver and kidney problems. It is safe as long as it is not taken in excess or prolonged use because it can lead to potentially life-threatening liver and kidney damage.
Take the drug as advised by the doctor (right dose and frequency). To be advised of the safest dose to take, also consult a clinical pharmacist.
