7. Product details

1. Why am I using Mevadol Forte?

Mevadol Forte contains three active ingredients,

  • paracetamol,
  • codeine phosphate hemihydrate, and
  • doxylamine succinate.

Paracetamol is an analgesic (pain-relieving medicine) and antipyretic (lowers body temperature). Codeine phosphate hemihydrate is a potent analgesic that helps to relieve pain. The body must convert codeine into morphine before it can provide pain relief. Doxylamine succinate is an antihistamine which can help to relieve tension and nausea associated with pain. This may be especially useful in the treatment of tension headache, migraine and period pain.

Mevadol Forte is used for the short-term management of severe pain for which other treatment options have failed, are not recommended, not tolerated or are otherwise inappropriate to provide sufficient management of pain. This may include toothache and other dental pain, pain from injury or surgery, or headache pain.

2. What should I know before I use Mevadol Forte?

Boxed Warnings

Limitations of use. Because of the risks associated with the use of opioids, Mevadol Forte should only be used in patients for whom other treatment options, including non-opioid analgesics, are ineffective, not tolerated or otherwise inadequate to provide appropriate management of pain (see Section 4.4 Special Warnings and Precautions for Use).
Hazardous and harmful use. Mevadol Forte poses risks of hazardous and harmful use which can lead to overdose and death. Assess the patient's risk of hazardous and harmful use before prescribing and monitor the patient regularly during treatment (see Section 4.4 Special Warnings and Precautions for Use).
Life threatening respiratory depression. Serious, life-threatening or fatal respiratory depression may occur with the use of Mevadol Forte. Be aware of situations which increase the risk of respiratory depression, modify dosing in patients at risk and monitor patients closely, especially on initiation or following a dose increase (see Section 4.4 Special Warnings and Precautions for Use).
Concomitant use of benzodiazepines and other central nervous system (CNS) depressants, including alcohol. Concomitant use of opioids with benzodiazepines, gabapentinoids, antihistamines, tricyclic antidepressants, antipsychotics, cannabis or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Limit dosages and durations to the minimum required; and monitor patients for signs and symptoms of respiratory depression and sedation. Caution patients not to drink alcohol while taking Mevadol Forte.

4 Clinical Particulars

4.9 Overdose

Elderly persons, small children, patients with liver disorders, chronic alcohol consumption or chronic malnutrition, as well as patients concomitantly treated with enzyme-inducing drugs, are at an increased risk of intoxication, including fatal outcome.
The intake of too high a dose of paracetamol can lead to impairment of liver function due to necrosis of liver cells, and this condition may progress to hepatic coma and may be fatal. Independently of these liver lesions, kidney damage as a result of necrosis of the renal tubules has also been reported.
Symptoms and signs of poisoning. The early stage of acute poisoning is typically characterized by nausea, vomiting, anorexia, pallor, abdominal pain, sweating and general malaise. This is usually followed by a 24 to 48-hour period in which the patient feels better; the symptoms however do not disappear altogether. The following stage is characterized by rapid increase in the size of the liver; serum transaminases and bilirubin rise, prothrombin time increases abnormally; urine excretion decreases and a slight increase in nitrogenous substances may develop. Three to five days after poisoning, the clinical features most typically encountered are commonly jaundice, fever, foetor hepaticus, abnormal bleeding tendency, hypoglycaemia, etc., as well as all stages of hepatic encephalopathy.
Nausea, vomiting, anorexia, pallor and abdominal pain generally appear during the first 24 hours of overdosage with paracetamol. Overdosage with paracetamol may cause hepatic cytolysis, which can lead to hepatocellular insufficiency, gastrointestinal bleeding, metabolic acidosis, encephalopathy, disseminated intravascular coagulation, coma and death. Increased levels of hepatic transaminases, lactate dehydrogenase and bilirubin with a reduction in prothrombin level can appear 12 to 48 hours after acute overdosage. It can also lead to pancreatitis, acute renal failure and pancytopenia.
Reactions associated with doxylamine succinate overdosage may vary from central nervous depression to stimulation. Stimulation is particularly likely in children. Atropine-like signs and symptoms, which include dry mouth, fixed dilated pupils, flushing and gastrointestinal symptoms, may also occur. Severe rhabdomyolysis after doxylamine succinate overdose has been reported in humans.
In an evaluation of codeine intoxication in children, symptoms ranked by decreasing order of frequency included sedation, rash, miosis, vomiting, itching, ataxia and swelling of the skin. Respiratory failure may occur. Blood concentrations of codeine ranged from 1.4 to 5.6 micrograms per mL in eight adults whose deaths were attributed to codeine overdosage.
The ingestion of very high doses of codeine can cause initial excitation, anxiety, insomnia (followed by drowsiness in certain cases), areflexia progressing to stupor or coma, headache, miosis, alterations in blood pressure, arrhythmias, dry mouth, hypersensitivity reactions, cold clammy skin, bradycardia, tachycardia, convulsions, gastrointestinal disorders, nausea, vomiting and respiratory depression.
Severe intoxication can lead to apnoea, circulatory collapse, cardiac arrest and death.
Treatment of poisoning. Despite lack of significant early symptoms, patients should be referred to hospital urgently for immediate medical attention.
Consists primarily of management of paracetamol toxicity; naloxone hydrochloride is the treatment of choice for codeine intoxication and must be administered intravenously. In cases of overdosage, methods of reducing the absorption of ingested drug are important. Prompt administration of 50 g activated charcoal and 500 mL iced mannitol 20% by mouth may reduce absorption.
Determinations of the plasma concentration of paracetamol are recommended. Plasma concentrations of paracetamol should be measured at 4 hours or later after ingestion (earlier concentrations are unreliable).
If the history suggests that 15 g paracetamol or more has been ingested, administer one of the following antidotes:
Acetylcysteine 20% IV. Administer 20% acetylcysteine immediately without waiting for positive urine test or plasma level results: initial dose 150 mg/kg over 15 minutes, followed by continuous infusion of 50 mg/kg in 500 mL 5% glucose over 4 hours and 100 mg/kg in 1 L 5% glucose over 16 hours; or
Oral methionine. 2.5 g methionine immediately followed by three further doses of 2.5 g at four hourly intervals. For a 3-year-old child, 1 g methionine 4-hourly for four doses has been used.
If more than ten hours have elapsed since the overdosage was taken, the antidote may be ineffective.
In general, treatment for codeine overdose should be symptomatic. Re-establish adequate respiratory exchange by ensuring a clear airway and using mechanical ventilation. When treatment for paracetamol toxicity has been initiated naloxone 400 microgram may be administered SC, IM or IV; IV may be repeated at intervals of 2 to 3 minutes if necessary. Assisted respiration may be required.
Further measures will depend on the severity, nature and course of clinical symptoms of intoxication and should follow standard intensive care protocols.
For information on the management of overdose, contact the Poisons Information Centre on 13 11 26 (Australia).
