Paracetamol (acetaminophen): Uses, Dose, Safety

Paracetamol (also called acetaminophen) is one of the easiest, safest medicines for pain and fever when used the right way. People take it for headaches, muscle aches, tooth pain, colds, and to lower fever. It works quickly and usually has few side effects at recommended doses.

How much should you take? For adults the common dose is 500–1000 mg every 4–6 hours as needed, with a maximum of 3000 mg per day for many guidelines, and 4000 mg per day only under medical advice. For children follow weight-based dosing on the label or ask a pharmacist. Never combine multiple products that both contain paracetamol.

Watch your liver. The biggest risk with paracetamol is overdose, which can damage the liver. Avoid alcohol while taking it, and don't exceed the daily limit. If you have liver disease, chronic alcohol use, or take other liver-affecting drugs, check with your doctor before using paracetamol.

Interactions and safety tips. Paracetamol has fewer interactions than many painkillers but it still matters. Some cold and flu medicines contain it, and some prescription drugs can affect its breakdown. Always read labels, tell your doctor all medications you take, and ask a pharmacist if unsure.

When to see a doctor

If your pain or fever lasts more than a few days, if you have severe abdominal pain, yellowing of the skin, dark urine, or confusion, seek medical help. For children under three months with a fever, see a doctor quickly. Serious allergic reactions to paracetamol are rare but need urgent care.

Alternatives and combining therapies

If paracetamol isn't enough, nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can help, but they have different risks such as stomach bleeding and kidney effects. For chronic pain, talk to your clinician about other options including physical therapy, topical treatments, or different medications. Sometimes alternating paracetamol and ibuprofen is recommended for children—follow pediatric advice.

Buying and storing paracetamol. Buy from licensed pharmacies and check expiry dates. Keep in original packaging and store at room temperature away from moisture. For online purchases, use reputable sites that require a prescription when needed and show clear contact information and shipping policies.

Quick tips to use it safely: 1) Know the exact dose for your age or weight. 2) Count total daily milligrams from all products. 3) Ask before mixing with alcohol or other medicines. 4) Keep it out of reach of children—small doses can be dangerous for kids.

Paracetamol works well for many short-term problems and is a good first choice for pain and fever. Use the right dose, watch for liver risks, and get medical help if symptoms are severe or don't improve. If you have questions about dose or interactions, your pharmacist is a fast and reliable resource.

Special groups: Pregnant or breastfeeding? Talk to your doctor—paracetamol is often preferred over NSAIDs but dose guidance matters. For overdose, call emergency services or a poison center immediately; early treatment with antidote can prevent liver damage. Save the medicine label and bring it to hospital immediately for help.
