Re: Diphenhydramine Injection Shortage
|Diphenhydramine injection supply is critically low. Estimates indicate less than a 2 week supply throughout NM Northwest system.|
|Diphenhydramine has been on shortage. Pharmacy Purchasing has been able to obtain orders up to this point.|
|In order to maintain the limited supply for crash cart exchange, sequestering to pharmacy and therapeutic substitution will need to be instituted.|
|Pharmacy will sequester remaining supply from Pyxis machines to the Pharmacy Department. Therapeutic Substitution will take place as follows:|
Injection to PO – For all patients who can take PO in equivalent dose.
If unable to take PO – Therapeutic substitution to Promethazine Injection in equivalent dose. Doses greater than 25 mg – consult with MD.
