Start with a conversation (what to ask)
“I’ve got a fever, a headache, and my throat really hurts… Is there an over-the-counter option?”
“Sorry you’re feeling rough. When did it start? What’s the highest temperature? Any chills, body aches, cough or runny nose? Are you keeping fluids down? Anyone around you with similar symptoms?”
“Since this morning. Fever around 38.5 °C with chills and joint aches. A little cough, hardly any runny nose. Drinking is okay.”
“Any medical conditions, regular medicines, allergies, or chance of pregnancy? (Blood thinners, stomach ulcers, kidney disease, heart failure, asthma: NSAIDs need caution.)”
“No chronic conditions. Not pregnant.”
“For fever and body aches, use acetaminophen or an NSAID (ibuprofen / loxoprofen). For throat pain, add a local option like a lozenge or throat spray. If you feel very unwell or worsen quickly, arrange testing/medical review sooner.”
Red flags — seek urgent care
- Stiff neck, “worst-ever” headache, confusion
- Shortness of breath, chest pain, bluish lips
- Unable to swallow saliva / drooling / trismus (possible peritonsillar abscess)
- Non-blanching rash (doesn’t fade when pressed)
- High fever persisting (≈ ≥38.5 °C for 3 days) or rapidly worsening
- Signs of dehydration (very dark/low urine, dizziness, dry mouth)
- Very young/older age, pregnancy, weakened immunity, serious conditions
- Severe headache with light sensitivity or repeated vomiting
If unsure, contact your local medical helpline or emergency service in your region.
What might it be? Quick clues
🔍 Influenza-like
- Sudden fever, chills, strong body aches and fatigue
- Local outbreak; testing and antivirals often considered if within ~48 h of onset
🔍 Group A strep (strep throat)-like
- Severe throat pain, swollen tonsils with white patches, tender neck nodes
- Usually little cough; may have a sandpaper-like rash
🔍 Viral sore throat / common cold
- Throat pain with mild cough/runny nose; fever often moderate
- Many improve over a few days with self-care
🔍 COVID-19 also possible
- Sore throat, fever, headache, fatigue; cough or loss of taste/smell may appear
- Recent exposure at home/work → consider testing
Final diagnosis requires a clinician. Pharmacists focus on triage and self-care support.
Choosing OTCs (by symptom)
Start with a single-ingredient pain/fever reducer
| Ingredient | Typical adult dose* | Best for | Key cautions |
|---|---|---|---|
| Acetaminophen (paracetamol) | 300–500 mg per dose, every 4–6 h as needed; daily max ~3,000 mg (JP OTC) |
Fever, headache, body aches; gentler on the stomach; preferred in pregnancy | Liver disease: consult a clinician. Watch for duplicate acetaminophen in combo cold meds. |
| Ibuprofen | 200 mg per dose, every 4–6 h PRN; daily max ~1,200 mg (OTC) |
Inflammatory pain/fever; helpful when throat swelling pain is prominent | Ulcer, kidney issues, heart failure, aspirin-sensitive asthma, blood thinners → caution. Avoid in late pregnancy. |
| Loxoprofen | 60 mg per dose, 2–3×/day | Fever and headache with quick relief | NSAID cautions (stomach/kidney/CV/ asthma). Avoid on an empty stomach. |
*Doses are general references. Always follow your local product label and your clinician’s advice.
Add local throat care
| Type | Examples | How to use |
|---|---|---|
| Lozenges / throat spray | Anti-inflammatory (e.g., flurbiprofen), local anesthetic (e.g., lidocaine) | Let lozenges dissolve slowly; spray toward the back of the throat. Avoid eating right after anesthetic sprays to prevent choking. |
| Gargle solutions | Povidone-iodine, etc. | Use short-term only; can irritate mucosa. Thyroid disease/iodine allergy → caution. |
| Cough/expectorants | When throat irritation triggers cough | Humidify air, sip warm fluids; honey works for ages ≥1 year. |
Age & situation matters
👶 Children
- Acetaminophen: 10–15 mg/kg/dose every 4–6 h; up to ~5 doses/day
- Ibuprofen: 5–10 mg/kg/dose (avoid under 6 months)
- Aspirin: generally avoid under 15 years (Reye’s syndrome risk)
- Honey is only for ages ≥1 year
🤰 Pregnancy & breastfeeding
- First choice: acetaminophen (use the lowest effective dose, shortest time)
- NSAIDs: avoid in late pregnancy
- Breastfeeding: acetaminophen/ibuprofen are generally compatible at usual doses
🩺 Conditions & interactions
- Blood thinners/antiplatelets: NSAIDs increase bleeding risk
- Ulcers, kidney disease, heart failure, uncontrolled hypertension: seek medical advice
- Watch duplicate ingredients when combining cold remedies with pain relievers
Home care you can start today
- Fluids + electrolytes: oral rehydration or diluted sports drinks, small sips often
- Throat care: humidify air, warm drinks, honey (≥1 y), avoid a dry throat
- Rest: stay home; even after fever settles, take it easy for 24 h
- Food: soft, easy-to-swallow options (soup, porridge, jelly)
- Fever comfort: use antipyretics for discomfort; change damp clothes after sweating
When to test or see a doctor
- Severe systemic symptoms or high fever: consider evaluation within ~48 h of onset (e.g., influenza testing/antivirals may be time-sensitive).
- Very painful throat with white patches: consider strep testing and treatment.
- Known exposure at home/work: consider COVID-19 testing.
- No improvement after 2–3 days of self-care, or if you worsen → seek care.
Don’t forget ID/insurance & water
FAQ
Q1. Should I take a fever reducer as soon as my temperature rises?
Use it for discomfort, not just a number. Fever helps your immune response; you don’t have to force a normal temperature if you’re otherwise coping.
Q2. Can I take a combo cold medicine and acetaminophen together?
Many combo products already contain acetaminophen — avoid double-dosing. Read labels and ask a pharmacist if unsure.
Q3. Are numbing throat sprays safe?
They can reduce the gag reflex briefly. Avoid eating immediately after use. If numbness lingers, space out doses.
Q4. What OTCs are okay for children?
Acetaminophen is the base; dose by body weight. Avoid ibuprofen under 6 months. Listless behavior, poor intake, or very low urine output → seek care.
Q5. What about during pregnancy?
First choice is acetaminophen. NSAIDs are avoided late in pregnancy. Don’t continue anything repeatedly without checking with your obstetric provider.
Q6. Do I need antibiotics?
Most cases are viral and don’t need antibiotics. Bacterial infections (like strep) require testing and prescription treatment.
