It is indicated for the symptomatic relief of occasional mild or moderate pain, such as headaches, dental pain, muscular pain, lumbago and in fever.

2. What you need to know before you take Paracetamol Hualan 650 mg Tablets

Do not take Paracetamol Hualan 650 mg Tablets:

  • If you are allergic (hypersensitive) to paracetamol or any of the other ingredients of Paracetamol Hualan 650 mg Tablets.

Warning and precautions

  • Do not take more medicine than recommended in section 3.
  • Taking this medicine with other medicines that contain paracetamol, for example flu or cold medicines, should be avoided, because high doses of paracetamol can lead to liver damage. Do not use more than one medicine that contains paracetamol without consulting a doctor.
  • Chronic alcoholics should be careful not to take more than 2 g of paracetamol in 24 hours.
  • Patients with kidney, liver, heart or lung diseases and patients with anemia should consult a doctor before taking this medicine. • If you are being treated with any medicines to treat epilepsy, you should consult your doctor before taking this medicine, because when used at the same time, the effectiveness is decreased and paracetamol liver toxicity is possible, especially in high-dose treatments of paracetamol.
  • Asthmatic patients sensitive to acetylsalicylic acid (aspirin) should consult their doctor before taking this medicine.

During treatment with Paracetamol, tell your doctor straight away if:

If you have severe illnesses, including severe renal impairment or sepsis (when bacteria and their toxins circulate in the blood leading to organ damage), or you suffer from malnutrition, chronic alcoholism or if you are also taking flucloxacillin (an antibiotic). A serious condition called metabolic acidosis (a blood and fluid abnormality) has been reported in patients in these situations when paracetamol is used at regular doses for a prolonged period or when paracetamol is taken together with flucloxacillin. Symptoms of metabolic acidosis may include: serious breathing difficulties with deep rapid breathing, drowsiness, feeling sick (nausea) and being sick (vomiting).

Children and adolescents

Not suitable for children and adolescents under 15 years old.

3. How to take Paracetamol Hualan 650 mg Tablets

Always take this medicine exactly as described in this leaflet or as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

The recommended dose is:

Adults and adolescents over 15 years old (weight >55 kg):

Swallow 1 tablet every 4-6hours, as needed. Do not take more than 6 tablets (equivalent to 3900 mg of Paracetamol) in 24 hours.

Patients with liver disease:

Before taking this medicine, you must consult your doctor.

You must take the amount of medicine prescribed by your doctor, with a minimum interval of 8 hours between each dose. You should not take more than 3 tablets of paracetamol in 24 hours, divided into 3 doses.

Patients with kidney disease:

Before taking this medicine, you must consult your doctor.

You should take 1 tablet every 8 hours. Paracetamol Hualan 650 mg Tablets are not indicated for patients with severe kidney disease.

The effective and safe use of Paracetamol Hualan 650 mg Tablets have not been established in children below the age of 14 years. Treatment is therefore not recommended in this population.

The tablets should be swallowed with a glass of liquid, preferably water. The tablets can be swallowed whole or broken in half; the tablets have a score line, which is only there to help you break the tablet if you have difficulty swallowing it whole.

Always take the lowest dose that is effective.

The use of high daily doses of paracetamol should be avoided for prolonged periods of time, because the risk of suffering adverse effects such as liver damage is increased.

Only take this medicine at the start of pain or fever symptoms and stop taking it when the symptoms disappear. If the pain lasts for more than 5 days, the fever lasts for more than 3 days, or if the pain or fever gets worse or other symptoms appear, you should stop the treatment and consult your doctor.

If you take more Paracetamol Hualan 650 mg Tablets than you should

You should immediately consult your doctor or pharmacist.

Talk to a doctor at once if you take too much of this medicine even if you feel well. This is because too much paracetamol can cause delayed, serious liver damage.

Symptoms of overdose may include: dizziness, vomiting, loss of appetite, yellowing of the skin and eyes (jaundice) and abdominal pain.

These symptoms often do not appear until 3 days after the overdose, even in cases of severe poisoning.

Treatment for an overdose is most effective if started within 4 hours of ingesting the medicine.

Patients being treated with barbiturates or chronic alcoholics may be more susceptible to the toxicity of an overdose of paracetamol.
