Should You Give Paracetamol for a Temperature of 38.6°C?
Yes, you can give paracetamol to your relative with a fever of 38.6°C, particularly if they are experiencing discomfort or pain alongside the fever. However, fever alone does not necessarily require treatment unless it is causing distress.
When Paracetamol Is Indicated
- Paracetamol is most appropriate when fever is accompanied by discomfort or pain, as it provides effective relief for both symptoms 1, 2.
- The standard adult dose is 650-1000 mg orally every 4-6 hours, with a maximum of 4 grams (4000 mg) per day 3.
- Paracetamol's antipyretic effect begins within hours but may take up to 4 hours to reach maximum effect, so patience is needed after administration 3, 4.
Important Context About Fever Treatment
Fever itself is not inherently dangerous and serves a protective physiological role 5. The evidence shows:
- In patients with infection, outcomes may actually be better with modest fever (38-38.4°C or even 39-39.4°C in some databases) compared to aggressive temperature reduction 5.
- Fever inhibits replication of certain bacteria like N. meningitidis and S. pneumoniae and helps with diagnosis of infection 5.
- In septic patients, paracetamol decreases temperature by only 0.3°C and does not affect mortality or ICU length of stay 5.
Clinical Decision Algorithm
Give paracetamol if:
- Your relative is uncomfortable, has pain, or is distressed by the fever 1, 2
- The fever is interfering with rest or quality of life 1
Consider withholding paracetamol if:
- The fever is well-tolerated without significant discomfort 2
- There is suspected infection where fever may be beneficial 5
If Fever Persists After Paracetamol
- If temperature remains above 38°C after 4 hours, paracetamol may be less effective at higher temperatures 4.
- Consider adding ibuprofen (an NSAID) as second-line therapy if fever persists and causes ongoing discomfort 4.
- Encourage fluid intake up to 2 liters daily to prevent dehydration 4.
- Physical cooling methods like tepid sponging can be added 4.
Critical Safety Considerations
- Do not use paracetamol with any other drugs containing acetaminophen to avoid accidental overdose 6.
- Do not exceed the maximum recommended dose of 4 grams per day in adults 3.
- Single ingestions of more than 10 times the recommended dose are potentially hepatotoxic 1.
- If your relative is allergic to acetaminophen, do not use it 6.
