Products Affected - Description
Amikacin injection, West-Ward (formerly Bedford product)
250 mg/mL, 2 mL vials, package of 10 (NDC 55390-0226-02)
250 mg/mL, 4 mL vials, package of 10 (NDC 55390-0226-04)
Reason for the Shortage
- West-Ward Pharmaceuticals’ parent company, Hikma Pharmaceuticals, acquired amikacin injection from Bedford in July 2014. West-Ward is not actively marketing amikacin 250 mg/mL 4 mL vials at this time.1
- Hospira discontinued amikacin in May, 2010 due to a raw material shortage.2
- Teva’s product was unavailable due to manufacturing delays.3
- Sandoz discontinued Amikin injection in 2006.4
- Heritage launched amikacin injection in March 2014.5

Implications for Patient Care
- Amikacin is an aminoglycoside antibiotic. It is effective against many Gram-negative bacteria, including some strains resistant to gentamicin or tobramycin.6-7 It is also effective against Staphylococcus aureus and some other Gram-positive bacteria.7 Amikacin is labeled for a variety of indications including bacterial septicemia, burn-related and post-operative infections, serious complicated and recurrent urinary tract infections, and serious bone and joint, intra-abdominal, central nervous system, respiratory tract, and skin and soft tissue infections.6
- Amikacin is the most active aminoglycoside against Mycobacterium avium complex (MAC). It is also effective against other drug-resistant, non-pulmonary Mycobacterium species, including M. abscessus, M. chelonae, and M. fortuitum. Gentamicin and tobramycin have poor activity against these Mycobacterium species. Streptomycin can be considered as part of a multi-drug treatment of drug-resistant Mycobacterium species.7-10
- Amikacin may be the aminoglycoside of choice for serious nosocomial gram-negative infections in areas where resistance to gentamicin or tobramycin is present.9 Amikacin is not degraded by many pathogen-produced enzymes that inactivate other aminoglycosides resulting in drug resistance.6,8
- Amikacin is a second-line treatment for drug-resistant Mycobacterium tuberculosis. Gentamicin and tobramycin are not considered effective treatments of M. tuberculosis. Streptomycin is also a second-line treatment of M. tuberculosis or a potential first-line alternative if other agents are contraindicated.9,10
- Amikacin is produced in 50 mg/mL and 250 mg/mL concentrations. Use caution when switching between amikacin products of different concentrations.9,10
- Target peak and trough concentrations, and timing of concentration measurement vary between aminoglycosides. Perform pharmacokinetic dosing calculations based on the specific agent being used.9,10
- Compounding pharmacies may be offering compounded amikacin products during this shortage. Extreme caution is warranted if a compounded product is used.11 Compounded products are not FDA-approved and FDA has no control over the quality or consistency of the manufacturing process.11,12 Compounding pharmacies may not test every batch of product for drug concentration, sterility, or lack of pyrogens. In July 2001, several patients died from bacterial meningitis after receiving betamethasone injection prepared by a compounding pharmacy.11,13
Alternative Agents & Management
- The choice of an alternative agent must be patient-specific and based on culture, sensitivity, desired tissue penetration, renal function, and site of infection. No single agent can be substituted for amikacin.7,9 Consult an Infectious Disease specialist for patient and infection-specific recommendations. Begin amikacin therapy only if sufficient supplies are available to complete the course of therapy.
- Consider reserving amikacin for use in patients with drug-resistant MAC and other drug-resistant non-pulmonary Mycobacterium species.9-10
- For other uses, consider using other parenteral aminoglycosides, such as gentamicin or tobramycin for susceptible infections. Streptomycin is primarily used as a second-line treatment of Mycobacterium tuberculosis.9,14 Table 1 briefly compares dosing and pharmacokinetics for the available aminoglycosides.
