- Pfizer Canada is currently experiencing a supply disruption of BICILLIN L-A (penicillin G benzathine) sterile injection due to a production issue.
- To alleviate the temporary shortage (expected resupply date of early July 2016), Health Canada, per the conditions agreed upon by Pfizer Canada, has facilitated the importation of Pfizer Australian labelled BICILLIN L-A, lot 72453.
- The Australian BICILLIN L-A is the same as the Canadian product with respect to composition, packaging (syringes), specification and expiry period (shelf life).
- Healthcare professionals should refer to the BICILLIN L-A Canadian Product Monograph for prescribing information. If administering Australian BICILLIN L-A in children under 2 years of age, it may be necessary to do dosage conversions.
During the temporary supply disruption of BICILLIN L-A (penicillin G benzathine) in Canada, Pfizer will be filling orders of the product with BICILLIN L-A, lot 72453, from Pfizer Australia. In light of this situation, Health Canada, per the conditions agreed upon by Pfizer Canada, facilitated the importation of Pfizer Australian labelled BICILLIN L-A, lot 72453. The Australian BICILLIN L-A is the same as Canadian product with respect to composition, packaging (syringes), specification and expiry period (shelf life). However, healthcare professionals need to be aware of the need to do dosage conversions when administering Australian BICILLIN L-A due to the difference in the expression of product strength as well as differences in the labelling of the syringe. The strength of the drug is expressed in "international units (I.U.)" in the Canadian BICILLIN L-A product label and in "mg" in the Australian BICILLIN product label (1.2 million I.U.= 900 mg).
Pfizer Canada BICILLIN L-A (penicillin G benzathine) sterile injection, available as a 2 mL disposable syringe containing 1.2 million I.U. penicillin G benzathine (as an aqueous suspension) and supplied in packages of 10 syringes.
BICILLIN L-A (benzathine benzylpenicillin) from Pfizer Australia, Lot 72453, has an expiry date of 2018.

Who is affected
Information for healthcare professionals
Healthcare professionals should consult the "Interim Syphilis Treatment Guidelines during the Benzathine Penicillin G (BICILLIN L-A) Shortage 2016" developed by the Public Health Agency of Canada.
Healthcare professionals should be aware of the differences in the syringe labelling of the Canadian BICILLIN L-A product and the Australian BICILLIN L-A product that is being supplied temporarily in its place. The Australian product is the same as the Canadian product with respect to composition, packaging (syringes), specification and expiry period (shelf life). There are differences in the nomenclature used on the label, however, the active ingredient and the non-medicinal ingredients in the Canadian and Australian BICILLIN L-A are the same. The volume of the two products is the same (i.e., 2.3 mL), except that the Canadian product is rounded down to 2mL.
