NHS high fever adults emergency symptoms 39.4 C
103°F (39.4°C) three hours after IV paracetamol can occur if the underlying illness is still driving the fever. The temperature not fully falling does not by itself mean the IV dose failed, but it needs clinical assessment, especially in a hospital patient.
- Do not give another paracetamol dose yet unless the treating clinician prescribes it. Usual IV dosing intervals are at least 4-6 hours, and total daily dose limits depend on age, weight, liver function, and all other paracetamol-containing medicines.
- Notify the doctor/nurse now for review of vital signs and cause of fever. They may need to assess for infection/sepsis, reaction to transfusion or medication, postoperative causes, dehydration, etc.
- While awaiting review: recheck temperature using a reliable method; monitor pulse, blood pressure, respiratory rate, oxygen saturation, urine output, and mental status. Use light clothing and tepid comfort measures, not ice baths or alcohol rubs.
Emergency escalation now if there is confusion/drowsiness, low blood pressure, fast or difficult breathing, oxygen desaturation, mottled/cold skin, seizure, severe headache or neck stiffness, rash, persistent vomiting, chest pain, or reduced urine output.
If this is a child, age and weight are essential because 1 g IV paracetamol may not be an appropriate dose for smaller children.
