Uganda Clinical Guidelines 2023 · all from source →

General Adult

Diagnosis

1.

Clinical Features — Early (0–24 hours)

Often asymptomatic initially. Nausea, vomiting, malaise. May appear deceptively well.

2.

Clinical Features — Late (24–72 hours)

Right upper quadrant abdominal pain. Jaundice. Liver failure (elevated transaminases, prolonged PT). Renal failure may develop.

3.

High Risk Thresholds

Single adult dose: >150 mg/kg or >7.5 g is potentially toxic. Toxicity is enhanced in patients with hepatic disease, chronic alcohol use, malnutrition, or on enzyme-inducing drugs.

Treatment

1.

If Presentation <2 Hours

Give activated charcoal 50 g (child: 1 g/kg) to reduce absorption. Refer urgently to hospital.

2.

Antidote — N-Acetylcysteine (HC4)

N-Acetylcysteine (NAC) IV: Loading dose 150 mg/kg in 200 ml glucose 5% over 15 minutes. Then 50 mg/kg in 500 ml glucose 5% over 4 hours. Then 100 mg/kg in 1000 ml glucose 5% over 16 hours. Most effective if given within 8 hours; still beneficial up to 24 hours.

3.

Monitoring

Monitor liver function tests, renal function, PT/INR, blood glucose. Refer for specialist management if liver failure develops.
