Paracetamol should be given with care to patients with impaired kidney or liver function. Paracetamol could interfere with paper chromatographic estimations of urinary amino acids by producing drug spots, and could interfere technically with laboratory estimations for metadrenalines in the urine to produce erroneous raised results. Paracetamol might interfere with the measurement of serum uric acid concentrations when the reagent used was phosphotungstic acid.
Allergy alert: Paracetamol may cause severe skin reactions. Symptoms may include skin reddening, blisters or rash. These could be signs of a serious condition. If these reactions occur, stop use and seek medical assistance right away.
