⚡ Quick Answer — What is Anacin?
Anacin is a paracetamol 500 mg tablet — a widely used analgesic (pain reliever) and antipyretic (fever reducer). Usual adult dose is 500 mg to 1 g (one to two tablets) every 4 to 6 hours as needed, with a maximum of 4 g (eight 500 mg tablets) per day from all sources combined. Paracetamol is the first-line painkiller for pregnancy, children, the elderly, and anyone who cannot take NSAIDs — it has no anti-inflammatory effect but is extremely safe at recommended doses.

Anacin 500 mg is a Pfizer/Wyeth brand of paracetamol (acetaminophen) widely available across India and parts of the Middle East. Paracetamol is on the WHO Essential Medicines List and is the most commonly used analgesic in the world.
Unlike NSAIDs (ibuprofen, diclofenac, naproxen), paracetamol does not have meaningful anti-inflammatory activity, but it is a strong central analgesic and antipyretic. That pharmacological profile makes it the safest first-line pain and fever medicine — with none of the NSAID risks to the stomach, kidneys, or platelets — which is why it is the preferred agent in pregnancy, in children, in older patients, and in anyone with a history of ulcer, kidney disease, asthma, heart failure, or bleeding disorders.
What Is Anacin Used For?
- Headache and migraine
- Dental pain, post-extraction pain
- Muscle ache, mild back pain, neck strain
- Fever of any cause — viral, bacterial, post-vaccination
- Menstrual pain (mild) — as first-line before or alongside NSAIDs
- Osteoarthritis pain (mild) — first-line in some guidelines, before NSAIDs
- Cold and flu symptoms — pain and fever
- Post-operative pain — multimodal analgesia, often combined with NSAID or opioid
How Does Paracetamol Work?
Paracetamol’s mechanism is still not fully understood despite decades of use. The leading explanation involves weak inhibition of cyclooxygenase in the central nervous system (spinal cord and brain), particularly the COX-3 variant that is abundant in these tissues, alongside modulation of endogenous cannabinoid and serotonergic pain-modulating pathways. The net effect is reduced pain perception and a lower body-temperature setpoint in the hypothalamus, without the peripheral anti-inflammatory action of NSAIDs.
Anacin Dosing
- Adults and children > 12 years: 500 mg to 1 g (1–2 tablets) every 4–6 hours as needed
- Maximum: 4 g (4,000 mg) per 24 hours from all sources combined
- Children 6–12 years: 250–500 mg every 4–6 hours, maximum 60 mg/kg/day
- Children under 6 years: use the paediatric suspension (Calpol) with weight-based dosing
- Elderly, low body weight (<50 kg), chronic liver disease, regular alcohol use: reduce the daily ceiling to 2–3 g
Tablets can be taken with or without food. Swallow with a full glass of water. If you miss a dose, take it when you remember unless the next scheduled dose is due within 2 hours — then skip.
Paracetamol and the liver. Paracetamol is extremely safe at recommended doses but is the single most common cause of acute liver failure worldwide at higher doses. Do not exceed 4 g (4,000 mg) per day from all sources combined. That is 8 tablets of 500 mg. Be careful not to double-dose by combining branded paracetamol (Calpol, Anacin, Panadol, Crocin, Tylenol) with cold/flu preparations that often also contain paracetamol. Liver risk rises with regular alcohol use, chronic liver disease, and prolonged fasting — reduce the daily limit to 2 g in those cases.
Who Should Not Take Anacin?
- Known hypersensitivity to paracetamol
- Severe hepatic impairment (advanced cirrhosis, active hepatitis)
- Chronic severe alcohol use without prior review
- Concurrent use of another paracetamol-containing product that would push the daily dose above 4 g
Side Effects
At recommended doses paracetamol has one of the cleanest safety profiles of any medicine.
- Uncommon: mild allergic rash, pruritus, nausea
- Rare: severe skin reactions (Stevens-Johnson syndrome), thrombocytopenia, liver injury at supra-therapeutic doses
- Overdose: acute hepatotoxicity — the single most important risk; symptoms (nausea, vomiting, right-upper-abdominal pain, sweating) may be delayed 24–48 hours. Any intentional or suspected overdose is a medical emergency — attend A&E immediately.

Frequently Asked Questions
What is Anacin used for?
Anacin (paracetamol 500 mg) is used for mild-to-moderate pain — headache, dental pain, muscle ache, menstrual pain, minor injuries — and for fever. It is one of the safest and most widely used pain relievers in the world.
How is paracetamol different from ibuprofen?
Paracetamol acts centrally (spinal cord and brain) and has no anti-inflammatory effect. Ibuprofen is an NSAID and acts on inflammation in the peripheral tissues. Both relieve pain and fever, but ibuprofen is better for inflammation-driven pain (arthritis, strains, dysmenorrhoea) while paracetamol is safer for long-term use and in high-risk patients.
How long does Anacin take to work?
Onset of pain and fever relief is usually within 30 minutes of an oral dose, with peak effect at 1 hour.
Can I take Anacin every day?
Short-term daily use is safe. For chronic daily use (e.g. chronic osteoarthritis), stay well within the 4 g/day ceiling, avoid combining with other paracetamol-containing products, and review with your doctor at least annually.
What happens if I take too much Anacin?
Doses above 150 mg/kg (about 10 g for a 65 kg adult) can cause severe liver injury, even if you feel well initially. Any suspected overdose is a medical emergency — N-acetylcysteine given within 8 hours is highly protective but must be started promptly. Attend A&E.
Can I take Anacin with ibuprofen, diclofenac, or aspirin?
Yes. Paracetamol works on a different pathway and can be safely combined with any NSAID. This is standard practice for moderate pain.
Is Anacin safe in pregnancy?
Yes. Paracetamol is the first-line pain and fever medicine in pregnancy. Use the lowest effective dose for the shortest duration, but do not delay treating a fever.
Is Anacin safe for children?
At weight-based doses, yes. For children under 6 years, the paediatric suspension (Calpol) is usually more convenient than breaking 500 mg tablets.
Can I drink alcohol while taking Anacin?
Occasional light drinking at standard paracetamol doses is acceptable. Regular or heavy alcohol use increases the risk of liver injury — reduce the daily ceiling to 2 g or avoid paracetamol altogether.
What’s the difference between Anacin and Calpol?
Both are paracetamol. Anacin is the Pfizer/Wyeth brand widely distributed across Asian markets. Calpol is the GlaxoSmithKline brand, historically focused on paediatric formulations (oral suspensions) but also available as adult tablets. At the same dose they are clinically equivalent.
What if I miss a dose of Anacin?
Take it when you remember, unless your next dose is due within 2 hours — then skip. Never double up to catch up.
