Doxycycline Expiration Extension Guidance

Share

FDA has published a guidance, Extending Expiration Dates of Doxycycline Tablets and Capsules in Strategic Stockpiles, to help government public health and emergency response stakeholders determine if stockpiled doxycycline tablets and capsules have retained their purity and potency beyond the manufacturer’s labeled expiration date so the replacement of stockpiled product could be deferred. The document refers to doxycycline tablets and capsules stockpiled by government stakeholders for public health emergency preparedness and response purposes for an anthrax emergency.

It applies to both doxycycline monohydrate and doxycycline hyclate tablets and capsules equivalent to 50 mg and 100 mg of doxycycline that are indicated for post-exposure prophylaxis or treatment of inhalational anthrax. The guidance and any resulting expiration date extensions authorized by FDA do not apply to doxycycline available commercially or otherwise held for any non-emergency purpose.

Covered in the document are an Introduction, Background, Discussion, and References.
