Reason for the Shortage
    • Amphastar has sodium bicarbonate injection available.[1]
    • Pfizer has sodium bicarbonate injection on shortage due to manufacturing delays.[2]
    • Fresenius Kabi has sodium bicarbonate injection temporarily available.[3]
Available Products
    • Sodium Bicarbonate injection, Amphastar, 8.4%, 50 mL syringe, 10 count, NDC 76329-3352-01
    • Sodium Bicarbonate injection, Fresenius Kabi, 4.2%, 5 mL vial, 25 count, NDC 63323-0083-05

Estimated Resupply Dates

    • Pfizer has sodium bicarbonate 4.2% 10 mL LifeShield syringes, 7.5% 50 mL syringes, and 8.4% 50 mL syringes available in limited supply. The 8.4% 10 mL syringes are on back order and the company estimates a release ate of September 2018. The 8.4% 50 mL vials are on back order and the company estimates a release date of November 2018.[2]
    • Pfizer has Neut 4% 5 mL vials on back order and the company estimates a release date of November 2018.[2]

Implications for Patient Care

    • Sodium bicarbonate injection is commonly used in critical care settings during advanced cardiac life support (ACLS). The product is also used to manage metabolic acidosis and hyperkalemia and to increase urinary pH. Sodium bicarbonate injection may be used as an antidote for selected products such as tricyclic antidepressants, methyl alcohol, phenobarbital, or salicylates.[4-5]
    • Some centers have used the injectable product to prepare extemporaneous oral solutions of omeprazole or lansoprazole.[6]


    • Few alternatives are available. Clinicians should make every effort to reserve supplies for critical care uses.
    • If using sodium acetate as an alternative, infuse the product over 15 to 20 minutes rather than 1 to 2 minutes with sodium bicarbonate.[8]
    • When drawing up doses from vials, ensure appropriate sterility measures are taken following USP <797> recommendations for batching.
    • Pfizer has issued a recall on 42 lots of sodium bicarbonate 8.4% 50 mL vials and Neut 4% additive solution due to sterility concerns.

Alternative Agents & Management

    • Conserve sodium bicarbonate for critical uses. Avoid using product for non-essential purposes such as buffering lidocaine during this shortage. The Society of Critical Care Medicine (SCCM) has recommendations for conserving sodium bicarbonate.
    • Evaluate vial use and consider methods to conserve supplies such as drawing up doses from vials rather than wasting unused product. Review storage locations such as crash carts and reduce inventory where possible.
    • If purchasing premade Continuous Renal Replacement Therapy (CRRT) solutions, consider those with higher sodium bicarbonate concentrations.
    • Sodium acetate injection may be an appropriate substitute for toxicology emergencies. The initial dose for salicylate overdose, severe cardiac arrhythmias, and initial rapid treatment of QRS widening is 1 mEq per kg body weight infused over 15 to 20 minutes with a goal serum pH of 7.5 to 7.55. Maintenance infusions are sodium acetate 150 mEq in 1 L 5% dextrose.[8]
    • Prepare oral solutions of omeprazole or lansoprazole using a sodium bicarbonate solution prepared from baking soda (1 teaspoon baking soda dissolved in 240 mL water).[7]
    • Oral sodium bicarbonate 650-mg tablets (Rising Pharmaceuticals, NDC 64980-0294-10) may be an appropriate alternative for urine alkalinization in patients receiving high-dose methotrexate.[9]
