Pentazocine (Talwin) originally was believed to be a safe, nonaddictive analgesic, but further experience has shown that severe mental and emotional disturbance, as well as addiction, may occur. This survey documents the experience in the Texas Medical Center and elsewhere. The accumulated data show the following: (1) Depressive states are reported most frequently, while toxic psychoses, hallucinogenic reactions with panic, and paranoid states on withdrawal of the drug are less frequent. (2) Of the 197 cases of addiction reported to date, only six were related to oral use of the drug. The abstinence syndrome is mild, consisting usually of restlessness, nausea, cramps, and insomnia. (3) Convulsions have been reported on four occasions. Euphoria and psychotomimetic effects may relate to rapid release of noradrenaline and dopamine. Oral use of the drug is advised to avoid euphoriant effects and addiction, and physicians should alert patients to report unusual visual phenomena. Tranquilizers are of value in cases of severe reactions.

We discuss the case of a 24-year-old black woman at 33--34 weeks gestation, who after intravenous injection of Talwin presented with the following symptom complex: pyrexia, nausea, vomiting, shaking, chills, headache, myalgias, polyarthralgias, severe abdominal pain and "contractions." This symptomatology presents a complex diagnostic problem. Systematic laboratory evaluation eliminated more common etiologies, i.e., sub-acute bacterial endocarditis, HAA + hepatitis, placental abruption, chorioamnionitis, and urinary tract infection. The Talwin had been filtered through cotton ball. History plus exclusion of other etiologies led to the diagnosis of "cotton fever." The available literature is reviewed, and the importance of recognizing this entity when servicing a pregnant population with a high rate of drug abuse is discussed.

Abuse of intravenous crushed Talwin (pentazocine) and Ritalin (methylphenidate) tablets has not been fully described. The objective of this study was to characterize intravenous pentazocine/methylphenidate abuse in emergency department patients and compare its clinical toxicity to pentazocine/tripelennamine. Cases of intravenous pentazocine/methylphenidate abuse presenting to the Truman Medical Center Emergency Department between August 1987 and November 1992 were identified. Information regarding patient demographics, drug abuse, chief complaints, evaluation, treatment, and disposition were obtained from the emergency department record. The clinical presentation was compared to 104 published cases of pentazocine/tripelennamine abuse. Twenty nine patients were treated 34 times. They were 32 +/- 9 years of age, 48% male, and 52% black. Patients' chief complaints were cardiovascular/pulmonary (N = 8), central nervous system (N = 7), localized infection (N = 7), gastrointestinal (N = 5), malaise (N = 5), trauma (N = 1), and gynecologic (N = 1). Treatment was primarily supportive and included supplemental oxygen and intravenous fluids. The clinical findings were similar to those reported for pentazocine/tripelennamine; 58% had the typical symptom complex of chest pain, anxiety, muscle spasm, dizziness, and nausea.
