By the pharmaranks editorial teamReviewed against the FDA (openFDA) sourcesUpdated Apr 23, 2025How we research

Chattem Inc recalled Unisom, SleepMinis, Diphenhydramine HCl, Mini-Capsules, 25 mg, 60 Mini-Capsules… in Mar 2025 — an FDA Class II recall (D-0362-2025) because CGMP Deviations; detection of Nitrosamine Drug Substance-Related Impurities (NDSRI), N-nitroso-desmethyl-diphenhydramine (n-dph), above the FDA Recommended Intake Limit.

May cause temporary or medically reversible harm; low probability of serious harm.

Why it was recalled

CGMP Deviations; detection of Nitrosamine Drug Substance-Related Impurities (NDSRI), N-nitroso-desmethyl-diphenhydramine (n-dph), above the FDA Recommended Intake Limit

An impurity above the accepted limit

A by-product of manufacturing or storage exceeded the limit the FDA accepts. Nitrosamines are the common example: the concern is long-term exposure, not immediate danger from one dose.

This is a manufacturing or quality failure, not a finding that the medicine is unsafe to take — across every recall we hold, none was issued for that reason. It does not mean the batch was harmless.
