What Paracetamol Is Used For
Paracetamol is commonly used to relieve:
- Headaches
- Joint pain, swelling, and stiffness
- Toothache
- Sore throat
- Fever and general aches associated with colds and flu
It works by reducing the production of certain chemicals in the body that cause pain and fever, providing relief without the anti-inflammatory action of medicines like ibuprofen.
How to Take 500mg Paracetamol Tablets
The following is general adult dosing guidance based on NHS information. Always check the packet or patient information leaflet for your specific product, as instructions can vary.
- One dose is 1 or 2 tablets (500mg or 1000mg)
- Leave at least 4 hours between doses
- Do not take more than 8 tablets (4000mg) in any 24-hour period
- Do not take Paracetamol for more than 3 days without speaking to a doctor
- Do not take other medicines that also contain paracetamol at the same time, including many cold and flu remedies, as this can lead to accidentally taking too much
If you weigh less than 50kg, a lower dose may be appropriate; check the packet or speak to a pharmacist.
Who Should Take Care of or Avoid Paracetamol
Most adults can take Paracetamol safely, but it may not be suitable if you:
- Have had an allergic reaction to paracetamol before
- Have a kidney or liver condition
- Are dependent on alcohol or drink heavily over short periods
Paracetamol is generally considered the safest painkiller option during pregnancy and breastfeeding, but you should always check with a healthcare professional if you have any concerns.
Taking Paracetamol with other medicines:
Some medicines do not mix well with paracetamol, including other paracetamol-containing products (such as cold and flu remedies), certain anti-sickness medicines, blood-thinning medicines like warfarin, and some antibiotics. Always check the leaflet or speak to a pharmacist if you take other medication regularly.
Paracetamol can generally be taken alongside ibuprofen if needed, and normal food, drink and alcohol consumption does not need to be restricted while taking it, though it is always sensible to use the lowest effective dose for the shortest time needed.
Side Effects
Paracetamol very rarely causes side effects when taken correctly at the recommended dose. Serious side effects are rare but can include allergic reactions, liver problems, or issues affecting blood cells. If you experience any unusual symptoms after taking Paracetamol, stop taking it and seek advice from a pharmacist or doctor.
If you think you have taken too much Paracetamol, even if you feel fine, contact NHS 111 or your nearest pharmacy immediately, as an overdose can cause serious liver damage that may not show symptoms right away. In an emergency, call 999.
