Secobarbital sodium The sodium salt of secobarbital is classified separately from the free acid, as follows: CAS number: 309-43-3 Chemical formula: C12H18N2NaO3 Molecular weight: 260.265 Side effects Possible side effects of secobarbital include: Somnolence Impaired motor functions Impaired coordination Impaired balance (Ataxia) Dizziness Anxiety Confusion Agitation, irritability, or excitability Headache Hunger Nausea Vomiting Nightmares Increased sensitivity to pain Allergic reactions Difficulty breathing Edema Urticaria Withdrawal Secobarbital may produce psychological addiction and produces physical dependence if used for an extended period of time. Withdrawal symptoms may occur if long-term use is abruptly ended and can include: Anxiety Insomnia Lack of appetite Seizures Tremors Possible death as a result of withdrawal Recreational and Lethal use Secobarbital was widely abused for recreational purposes in the 1960s, 1970s, and 1980s, and accidental overdose was associated with the drug. Lilly's Seconal came in a bright orange/red bullet shaped capsule known as a Pulvule. Prescription use of secobarbital decreased beginning in the early 1980s by which time benzodiazepines had become increasingly common. Secobarbital has acquired many nicknames, the most common being "reds," "red devils," or "red dillies" (because of the color of the capsules). Other common nicknames are "seccies," "Cardinals," "ruby slippers," and, according to the Wegman's School of Pharmacy curriculum, "red hearts". A less common nickname is "dolls"; this was partly responsible for the title of Jacqueline Susann's novel Valley of the Dolls, whose main characters use secobarbital and other such drugs. Actresses Carole Landis, Judy Garland, and journalist Dorothy Kilgallen allegedly either died by suicide or of accidentally overdosing on secobarbital. Seconal was used to induce Fred Hampton into docility before he was then executed in his bed in the early hours of December 4,1969. In 1978, 1000 pills of Seconal were recovered in Jonestown, along with substantial quantities of Valium, Thorazine, Talwin, Demerol, and other sedatives, hypnotics, and analgesics.
