Addiction: part II. Identification and management of the drug-seeking patient.

The medications most often implicated in prescription drug abuse are opioid analgesics, sedative-hypnotics and stimulants. Patients with acute or chronic pain, anxiety disorders and attention-deficit disorder are at increased risk of addiction comorbidity. It is important to ask patients about their substance-use history, including alcohol, illicit drugs and prescription drugs. Patients who abuse prescription drugs may exhibit certain patterns, such as escalating use, drug-seeking behavior and doctor shopping. A basic clinical survival skill in situations in which patients exert pressure on the physician to obtain a prescription drug is to say "no" and stick with it. Physicians who overprescribe can be characterized by the four "Ds"-dated, duped, dishonest and disabled. Maintaining a current knowledge base, documenting the decisions that guide the treatment process and seeking consultation are important risk-management strategies that improve clinical care and outcomes.
