Uses and warnings
Key warnings include: - Dependence/Withdrawal: "Certain adverse clinical events, some life-threatening, are a direct consequence of physical dependence." Even at recommended doses, dependence risk exists; risk increases above 4 mg/day. Seizures can occur during discontinuation. - CNS Depression: Patients should avoid "hazardous occupations or activities requiring complete mental alertness such as operating machinery or driving." - Pregnancy: Benzodiazepines "potentially cause fetal harm when administered to pregnant women"; avoid during first trimester. - CYP3A Interactions: Contraindicated with ketoconazole and itraconazole due to dangerous metabolic interactions. ---
Alprazolam tablets treat two primary conditions: Anxiety Disorders: "management of anxiety disorder" corresponding to generalized anxiety disorder, or "short-term relief of symptoms of anxiety." The label specifies that everyday stress-related anxiety typically doesn't warrant treatment. Panic Disorder: "treatment of panic disorder, with or without agoraphobia." Clinical studies demonstrated effectiveness over 4-10 weeks, though some patients received treatment up to 8 months without apparent loss of benefit. ---
