6.1 Clinical

Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data in the two tables below are estimates of adverse reaction incidence among adult patients who participated in:

4-week placebo-controlled clinical studies with XANAX dosages up to 4 mg per day for the acute treatment of generalized anxiety disorder (Table 1)

Short-term (up to 10 weeks) placebo-controlled clinical studies with XANAX dosages up to 10 mg per day for panic disorder, with or without agoraphobia (Table 2). Table 1: Adverse Reactions Occurring in ≥1% in XANAX-treated Patients and Greater than Placebo-treated Patients in Placebo-Controlled Trials for Generalized Anxiety XANAX n=565 Placebo n=505 Nervous system disorders Drowsiness 41% 22% Light-headedness 21% 19% Dizziness 2% 1% Akathisia 2% 1% Gastrointestinal disorders Dry mouth 15% 13% Increased salivation 4% 2% Cardiovascular disorders Hypotension 5% 2% Skin and subcutaneous tissue disorders Dermatitis/allergy 4% 3% In addition to the adverse reactions (i.e., greater than 1%) enumerated in the table above for patients with generalized anxiety disorder, the following adverse reactions have been reported in association with the use of benzodiazepines: dystonia, irritability, concentration difficulties, anorexia, transient amnesia or memory impairment, loss of coordination, fatigue, seizures, sedation, slurred speech, jaundice, musculoskeletal weakness, pruritus, diplopia, dysarthria, changes in libido, menstrual irregularities, incontinence and urinary retention.

Adverse Reactions Reported as Reasons for Discontinuation in Treatment of Panic Disorder in Placebo-Controlled Trials In a larger database comprised of both controlled and uncontrolled studies in which 641 patients received XANAX, discontinuation-emergent symptoms which occurred at a rate of over 5% in patients treated with XANAX and at a greater rate than the placebo-treated group are shown in Table 3. Table 3: Discontinuation-Emergent Symptom Incidence Reported in ≥5% of XANAX-treated Patients and > Placebo-treated Patients n=number of patients. XANAX-treated Patients n=641 Nervous system disorders Insomnia 29.5% Light-headedness 19.3% Abnormal involuntary movement 17.3% Headache 17.0% Muscular twitching 6.9% Impaired coordination 6.6% Muscle tone disorders 5.9% Weakness 5.8% Psychiatric disorders Anxiety 19.2% Fatigue and Tiredness 18.4% Irritability 10.5% Cognitive disorder 10.3% Memory impairment 5.5% Depression 5.1% Confusional state 5.0% Gastrointestinal disorders Nausea/Vomiting 16.5% Diarrhea 13.6% Decreased salivation 10.6% Metabolism and nutrition disorders Weight loss 13.3% Decreased appetite 12.8% Dermatological disorders Sweating 14.4% Cardiovascular disorders Tachycardia 12.2% Special Senses Blurred vision 10.0% There have also been reports of withdrawal seizures upon rapid decrease or abrupt discontinuation of XANAX. Paradoxical reactions such as stimulation, increased muscle spasticity, sleep disturbances, hallucinations, and other adverse behavioral effects such as agitation, rage, irritability, and aggressive or hostile behavior have been reported rarely. In many of the spontaneous case reports of adverse behavioral effects, patients were receiving other CNS drugs concomitantly and/or were described as having underlying psychiatric conditions. Should any of the above events occur, alprazolam should be discontinued. Isolated published reports involving small numbers of patients have suggested that patients who have borderline personality disorder, a prior history of violent or aggressive behavior, or alcohol or substance abuse may be at risk for such events. Instances of irritability, hostility, and intrusive thoughts have been reported during discontinuation of alprazolam in patients with posttraumatic stress disorder.

6.2 Postmarketing

Experience The following adverse reactions have been identified during postapproval use of XANAX. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Endocrine disorders: Hyperprolactinemia General disorders and administration site conditions: Edema peripheral Hepatobiliary disorders: Hepatitis, hepatic failure Investigations: Liver enzyme elevations Psychiatric disorders: Hypomania, mania Reproductive system and breast disorders: Gynecomastia, galactorrhea Skin and subcutaneous tissue disorders: Photosensitivity reaction, angioedema, Stevens-Johnson syndrome
