6/27/2010
 

Dear Healthcare Provider :

Saudi Food and Drug Authority would like to draw the attention of healthcare professionals to the risk of accidental overdose in neonates and infants during treatment with intravenous paracetamol 10 mg/ml solution for infusion which is marketed in Saudi Arabia as PERFALGAN®; available in 100 ml vials. The warning of risk of overdose is based on information available from the company (Bristol Myers Squibb).

Perfalgan® can be indicated for the short-term treatment of moderate pain, especially following surgery, and for the short-term treatment of fever, when administration by intravenous use is clinically justified by an urgent need to treat pain or hyperthermia and/or when other routes of administration are not possible in children weighing less than 33 kg.

o Up to 31 March 2010, the company received 23 worldwide cases of intravenous paracetamol overdose had been reported in children aged less than 1 year old. One child subsequently died.
o There are concerns regarding the possible confusion between the prescription of PERFALGAN® being issued in mg and then administered in ml.

With this in mind, we would like to remind you that the strength of PERFALGAN® solution for infusion is 10 mg paracetamol per 1 ml solution and encourage you to be extremely vigilant when prescribing and administering PERFALGAN® 10mg/ml solution for infusion to infants and children.
