When a fever hits, quick relief matters—but not all fever reducers are the same. Know which medicines work, how to dose them, and when to call a doctor. This guide gives practical tips so you can act fast and smart.
Acetaminophen (paracetamol) and ibuprofen are the two most common options. Acetaminophen eases pain and lowers fever without irritating the stomach. Ibuprofen is an NSAID that also reduces inflammation. Both are effective, but the choice depends on age, allergies, and health conditions.
Adults: acetaminophen 500–1000 mg every 4–6 hours, max 3,000–4,000 mg per day depending on product. Ibuprofen 200–400 mg every 4–6 hours, max 1,200 mg per day over the counter. Read labels—some products add other drugs that change the total dose.
Children: dose by weight, not age. For acetaminophen use 10–15 mg per kg every 4–6 hours. For ibuprofen use 5–10 mg per kg every 6–8 hours. Never give aspirin to children or teens with viral illnesses because of the risk of Reye’s syndrome.
Never mix full doses of acetaminophen and ibuprofen at the same time without medical advice. Alternating them can help in some cases, but keep a clear schedule and track timing to avoid accidental overdose.
Avoid ibuprofen if you have active stomach ulcers, certain kidney problems, or are taking blood thinners unless your doctor okays it. Avoid high acetaminophen doses if you drink alcohol regularly or have liver disease. Pregnant people should check with their provider—acetaminophen is usually preferred, but talk to your clinician.
Fever is usually a symptom, not the disease. If a fever comes with severe headache, stiff neck, rash, difficulty breathing, repeated vomiting, confusion, or persistent high fever (over 39.4°C/103°F in adults or lasting more than 48 hours), seek medical care right away.
For babies under three months with a rectal temperature of 38°C (100.4°F) or higher, call your pediatrician immediately. For older infants and toddlers, trust your instincts—if the child looks very unwell, get medical help.

Other ways to help: stay hydrated, rest, and use lightweight clothing. Lukewarm sponge baths can help, but avoid cold baths or alcohol rubs. For sore throats or congestion pair fever reducers with supportive care like fluids and saline sprays.
If you’re unsure which fever reducer fits your health profile, ask a pharmacist or doctor. A quick call can prevent mistakes and make sure you pick the safest option for you or your child.
Keep a medicine log at home: note time, dose, and symptom changes. That helps if you see a doctor or mix medications. Store all medicines out of children's reach and check expiration dates. When in doubt, contact your healthcare provider for clear, personalized advice right away.
