123 PILL – Identification, Dosage, Side Effects
The round, white pill debossed with the imprint “123” on one side (and frequently “BAC” on the reverse) is a generic combination formulation of Butalbital, Acetaminophen, and Caffeine (50 mg / 325 mg / 40 mg).
Commonly known by brand names such as Fioricet or Esgic, this specialized multi-ingredient medication is primarily prescribed to treat complex headaches. Because it contains a barbiturate, its legal classification and controlled substance status vary by state and federal jurisdiction due to its potential for misuse, physical dependence, and addiction.
