OVERVIEW

What is paracetamol?

Paracetamol is the active salt in many familiar India medicine brands, including products sold for fever and pain. It is also called acetaminophen in some countries. It is available as tablets, capsules, oral liquids, drops, suppositories and injections.

Brand names are not enough for safe use. Always match the active salt, strength, dosage form and route written on your pack. A 500 mg tablet, 650 mg tablet, children’s syrup and injection are not interchangeable.

USES

What is paracetamol used for?

Paracetamol is used to lower fever and relieve mild-to-moderate pain. Common examples include headache, body ache, toothache, menstrual pain, muscular pain and discomfort during a short illness.

It does not cure an infection or remove the cause of pain. It is not an antibiotic and it is not the same as an anti-inflammatory medicine. Persistent or severe symptoms need medical assessment.

SAFE USE

The most important paracetamol safety rule

Do not take more than one paracetamol-containing product without checking the composition. Paracetamol can appear in fever tablets, pain tablets, cold-and-flu products, cough products, headache medicines and night-time preparations.

The total daily amount, not only the number of one brand’s tablets, determines overdose risk. Keep a written record when more than one person is giving medicines.

DOSE & MAXIMUM

Paracetamol dose and maximum dose: why the exact product matters

Paracetamol dosing depends on the strength, dosage form, age, body weight, liver health and other medicines. Tablets, drops and liquids need different measurement methods. A child’s dose must be calculated from the child’s own weight and the exact bottle concentration, not from an adult tablet.

For adult 650 mg paracetamol tablets, product information commonly uses one tablet at a time with at least 4 to 6 hours between doses, and no more than six 650 mg tablets in 24 hours. A clinician may set a lower maximum for people with liver disease, low body weight, malnutrition, heavy alcohol use or other risks.

Do not continue self-treatment for more than 3 days without medical advice if pain or fever remains.

SIDE EFFECTS

Paracetamol side effects and danger signs

Paracetamol is usually well tolerated at the correct dose. Nausea, stomach discomfort, itching or a rash can occur. Rare but serious reactions include allergic swelling, breathing trouble, severe skin rash, blistering, mouth ulcers, unexplained bruising/bleeding and liver injury after overdose.

Urgent help is needed after a possible extra dose even when the person feels fine. Liver injury may not cause immediate symptoms.

SPECIAL GROUPS

Children, pregnancy, breastfeeding and liver disease

Children need a child-appropriate formulation and weight-based guidance. Do not cut down an adult tablet or estimate syrup with a kitchen spoon.

In pregnancy and breastfeeding, ask the doctor or pharmacist who knows the person’s health and other medicines. The usual aim is the lowest effective amount for the shortest time.

Check first before paracetamol in liver disease, regular heavy alcohol use, severe malnutrition, very low body weight, kidney disease, serious infection or when taking warfarin or other regular medicines.

COMMON QUESTIONS

Paracetamol FAQs

What is paracetamol used for?

Paracetamol lowers fever and helps mild-to-moderate pain. It does not cure the underlying infection or other cause of symptoms.

Is paracetamol and Dolo the same?

Dolo is a brand family. Dolo 650 commonly contains paracetamol 650 mg, but always read your own strip because brands can have variants.

Can I use two paracetamol brands together?

Do not combine them unless you have checked the total paracetamol amount. Different brands can contain the same salt.

Can children take paracetamol?

Yes, child-appropriate paracetamol products are used for children when suitable, but the dose must be based on the child’s weight, age and exact formulation. Do not use an adult tablet as a shortcut.

What should I do after taking too much paracetamol?

Seek urgent medical care immediately even if you feel well. Bring the product packs and a record of everything taken.
