The U.S. OTC label sets the maximum at 6 tablets (1,200 mg) in any 24-hour period — that is 6 × 200 mg. Do not take more than directed. If 6 tablets in 24 hours are not handling your pain, talk to a doctor or pharmacist instead of exceeding the label.
Every 4–6 hours while symptoms last, per the label. The scheduler above applies your chosen 4- or 6-hour interval to the doses you log and shows the earliest next dose. Use the smallest effective dose.
Only if 1 tablet does not help: the label allows 2 tablets (400 mg) in that case. It is not a standing double dose — keep using the smallest effective dose, and never exceed 6 tablets (1,200 mg) in 24 hours.
The label rules: 10 mg/kg per dose every 6–8 hours, with a maximum of 40 mg/kg in 24 hours, measured from the 100 mg/5 mL suspension. Use the child's weight when possible, shake well, and use the enclosed dosing cup or an oral syringe. Do not give more than 4 times a day. Children under 6 months should ask a doctor first — this tool does not estimate doses for them.
The suspension is 100 mg per 5 mL, i.e. 20 mg per mL: mL = mg ÷ 20. Example: a 20 kg child → 200 mg per dose → 10 mL. The calculator above does this conversion and rounds to a measurable quarter-mL. Never use a kitchen spoon.
Per the label: stop use and ask a doctor if pain gets worse or lasts more than 10 days, or if fever gets worse or lasts more than 3 days. The schedulers flag this when you enter consecutive days.
Per the label's Warnings: anyone with a stomach ulcer or GI bleeding history; kidney disease; high blood pressure, heart disease, liver disease, asthma, or a past stroke; an aspirin/NSAID allergy; anyone taking a blood thinner, steroid, or another NSAID; people having 3+ alcoholic drinks daily; and anyone pregnant or breastfeeding. The safety self-check above walks through these one by one.
Ask a health professional first. The label says it is especially important not to use ibuprofen at 20 weeks of pregnancy or later unless a doctor definitely directs it, because of risks to the unborn child. Do not decide this from a web tool.
No — not on your own. Both are NSAIDs, and combining them raises the risk of stomach bleeding and kidney problems without clear benefit. If one is not working, talk to a doctor or pharmacist instead of layering them.
Both are OTC NSAIDs for pain and fever; the drugs and labels differ. Ibuprofen: 200 mg every 4–6 hours, max 1,200 mg per day, lasts 4–6 hours per dose, with a children's weight-based suspension. Naproxen (Aleve): 220 mg every 8–12 hours, max 660 mg per day, lasts up to 12 hours per dose, and under-12s should ask a doctor (no OTC weight chart). See the comparison table above. This tool does not recommend one over the other — a pharmacist can help you choose.
The label says to take it with food or milk if stomach upset occurs. That may ease stomach discomfort for some people, but it does not remove the underlying stomach-bleeding risk of NSAIDs.
Get medical help right away or contact Poison Control immediately — do not wait for symptoms. Signs of NSAID overdose can include nausea, vomiting, stomach pain, and drowsiness, and in serious cases breathing difficulty. Do not take any more until a professional advises you.
Ages 12 and up follow the same label directions as adults: 1 tablet (200 mg) every 4–6 hours, max 6 tablets (1,200 mg) per 24 hours. A parent, guardian, pharmacist, or doctor should confirm use for anyone under 18.
No. It is an educational estimate that applies the U.S. OTC Drug Facts label rules (200 mg per tablet, 1 tablet every 4–6 hours, max 6 tablets / 1,200 mg per 24 hours, 12+ only, 10-day / 3-day limits; children: 10 mg/kg per dose every 6–8 hours, max 40 mg/kg per 24 hours, 6+ months only) to the doses you log. It does not know your health history, other medicines, or conditions. Always follow the label on your package and check with a doctor or pharmacist when unsure.
