Arm Intervention/treatment
Experimental: Paracetamol
Patients will receive paracetamol intravenously (1 g in 100 mL) over 15 minutes (single dose), as an analgesic during the first stage of labor, given by a member of the study team.
Drug: Paracetamol
Active Comparator: Pethidine
Slow intravenous administration of pethidine, 50 mg to be diluted in 10 mL of sterile water (single dose), as an analgesic during the first stage of labor, given by a member of the study team.
Drug: Pethidine

Primary Outcome Measures :
  1. The efficacy of intravenous paracetamol to supply adequate analgesia as indicated by changes in the pain intensity score using the visual analog scale. [ Time Frame: 4 hours ]
    Assessment is to be done and followed up by the investigator at ½, 1, 2, 3 and 4 hours from drug administration. Scores range from 0 [no pain] to 10 [worst possible pain].
