This article provides a clear overview of the SG 109 pill, including what it is used for and how to identify it accurately.
What Is the SG 109 Pill?
The SG 109 pill is a white, round tablet that is imprinted with “SG 109” on one side. This pill is commonly identified as Diphenhydramine Hydrochloride 25 mg, which is an over-the-counter medication often used for several purposes.
Diphenhydramine is most widely known by its brand name Benadryl, but it is available in various generic forms as well, including those marked with identifiers like pill SG 109.
