Gentamicin Injection USP (10 mg/mL and 40 mg/mL) – Potential for Adverse Reactions with 12 Lots Contaminated with Histamine
- Starting date:
- June 29, 2017
- Posting date:
- July 3, 2017
- Type of communication:
- Dear Healthcare Professional Letter
- Source of recall:
- Health Canada
- Important Safety Information
- Healthcare Professionals
- Identification number:
Healthcare professionals including pediatricians, urologists, gynaecologists, respirologists, surgeons, internists, pharmacists, nurses, and emergency room staff.
- Gentamicin Injection USP (10 mg/mL and 40 mg/mL) is indicated for the treatment of serious, potentially life-threatening, infections, in adults and children.
- Twelve lots of Gentamicin Injection USP manufactured at Sandoz Canada Inc. may contain traces of histamine.
- Histamine administered intravenously or intramuscularly could potentially lead to signs and symptoms of anaphylaxis, particularly in pediatric patients and patients with severe renal impairment.
- Although the likelihood of this adverse event is rare, healthcare professionals are advised, when administering Gentamicin Injection USP, to closely monitor all patients for adverse reactions associated with elevated levels of histamine.
Sandoz has identified histamine contamination in 3 Active Pharmaceutical Ingredient (API) batches used to manufacture 12 lots of Gentamicin Injection USP. The 3 API batches were tested for histamine levels. One batch had a level of 5 ppm (5 mcg/g), and the other 2 batches had a level less than the limit of quantification.
|Product Description||DIN||Code||Lot||Expiry Date|
|GENTAMICIN 10MG/ML 2ML 10LIVI CA||02268531||44005211||FH8171||2017-05-31|
|GENTAMICIN 40MG/ML 2ML 10LIVI CA||02242652||44005212||GB3917||2018-02-28|
Gentamicin Injection USP (10 mg/mL and 40 mg/mL), a medically necessary drug, is indicated for the treatment of serious, potentially life-threatening, infections, in adults and children.
Histamine, produced by certain white blood cells and found throughout connective tissues in the body, plays a key role in inflammatory responses, including anaphylactic reactions. Although no information on the safety of intramuscular histamine administration in humans was identified, the literature does suggest that as little as 7 mcg of histamine administered intravenously in adults can trigger vasodilatation and increased heart rate. Similar information could not be found for pediatric patients. Based on the testing of the API batches, the amount of histamine that may be found in a daily adult dose of affected Gentamicin for Injection USP is expected to be below the 7 mcg level.
Who is affected
Information for consumers
Gentamicin Injection USP is used only to treat serious and life-threatening infections that are proven or strongly suspected to be caused by certain bacteria. Gentamicin Injection USP is generally administered by healthcare professionals, either as an injection into a muscle or directly into a vein.
During the manufacturing of Sandoz Gentamicin Injection USP, some lots of the product were contaminated with a substance called histamine. When injected into the body, this could potentially lead to side-effects similar to those experienced during life-threatening allergic reactions. Sandoz and Health Canada are letting healthcare professionals know that they need to take extra precautions and to monitor patients when giving the medication.
Information for healthcare professionals
All patients being administered affected Gentamicin Injection USP lots should be monitored closely for potential adverse reactions associated with increased levels of histamine (see Products affected section). In particular, the daily amount of histamine that could trigger adverse reactions in the pediatric population is unknown. Additionally, patients with severe renal impairment may be more susceptible to the antihypertensive effects of exogenous histamine. Therefore, pediatric patients and patients with severe renal impairment should be monitored more closely.
