Adverse Reactions
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: • Risks from Concomitant Use with Opioids [see Warnings and Precautions (5.1) ] • Abuse, Misuse, and Addiction [see Warnings and Precautions (5.2) ] • Dependence and Withdrawal Reactions [see Warnings and Precautions (5.3) ] • Effects on Driving and Operating Machinery [see Warnings and Precautions (5.4) ] • Patients with Depression [see Warnings and Precautions (5.7) ] • Neonatal Sedation and Withdrawal Syndrome [see Warnings and Precautions (5.8) ] • Risks in Patients with Impaired Respiratory Function [see Warnings and Precautions (5.9) ] The most common adverse reactions in panic disorder patients treated with alprazolam XR (incidence of ≥ 5% and at least twice that of placebo) include: somnolence, memory impairment, dysarthria, coordination abnormal, ataxia, libido decreased, constipation, and nausea.

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 information included in the section on Adverse Reactions Observed in Short-Term, Placebo-Controlled Trials with Alprazolam XR is based on pooled data of five 6- and 8-week placebo-controlled clinical studies in panic disorder.
Adverse Reactions Observed in Short-Term, Placebo-Controlled Trials of Alprazolam XR Adverse Reactions Reported as Reasons for Discontinuation of Treatment in Placebo-Controlled Trials Approximately 17% of the 531 patients who received alprazolam XR in placebo-controlled clinical trials for panic disorder had at least 1 adverse event that led to discontinuation compared to 8% of 349 placebo-treated patients.
The most common events leading to discontinuation and considered to be drug-related (i.e., leading to discontinuation in at least 1% of the patients treated with alprazolam XR at a rate at least twice that of placebo) are shown in Table 1.

The most commonly observed adverse reactions in panic disorder patients treated with alprazolam XR (incidence of 5% or greater and at least twice the incidence in placebo patients) were: sedation, somnolence, memory impairment, dysarthria, coordination abnormal, ataxia, libido decreased.

Adverse reactions are further categorized by body system and listed in order of decreasing frequency according to the following definitions: those occurring in at least 1/100 patients (frequent); those occurring in less than 1/100 patients but at least 1/1000 patients (infrequent); those occurring in fewer than 1/1000 patients (rare).
Cardiac disorders: Frequent: palpitation; Infrequent: sinus tachycardia Ear and labyrinth disorders: Frequent: vertigo; Infrequent : tinnitus, ear pain Eye disorders: Frequent: blurred vision; Infrequent: mydriasis, photophobia Gastrointestinal disorders: Frequent: diarrhea, vomiting, dyspepsia, abdominal pain; Infrequent: dysphagia, salivary hypersecretion General disorders and administration site conditions: Frequent: malaise, weakness, chest pains; Infrequent: fall, pyrexia, thirst, feeling hot and cold, edema, feeling jittery, sluggishness, asthenia, feeling drunk, chest tightness, increased energy, feeling of relaxation, hangover, loss of control of legs, rigors Musculoskeletal and connective tissue disorders: Frequent: back pain, muscle cramps, muscle twitching Nervous system disorders: Frequent: headache, dizziness, tremor; Infrequent: amnesia, clumsiness, syncope, hypotonia, seizures, depressed level of consciousness, sleep apnea syndrome, sleep talking, stupor Psychiatric system disorders: Frequent: irritability, insomnia, nervousness, derealization, libido increased, restlessness, agitation, depersonalization, nightmare; Infrequent: abnormal dreams, apathy, aggression, anger, bradyphrenia, euphoric mood, logorrhea, mood swings, dysphonia, hallucination, homicidal ideation, mania, hypomania, impulse control, psychomotor retardation, suicidal ideation Renal and urinary disorders: Frequent: difficulty in micturition; Infrequent: urinary frequency, urinary incontinence Respiratory, thoracic, and mediastinal disorders: Frequent: nasal congestion, hyperventilation; Infrequent: choking sensation, epistaxis, rhinorrhea Skin and subcutaneous tissue disorders: Frequent: sweating increased; Infrequent: clamminess, rash, urticaria Vascular disorders: Infrequent: hypotension Discontinuation-Emergent Adverse Reactions Occurring at an Incidence of 5% or More Among Patients Treated with Alprazolam XR Table 3 shows the incidence of discontinuation-emergent adverse reactions that occurred during short-term, placebo-controlled trials in 5% or more of patients treated with alprazolam XR where the incidence in patients treated with alprazolam XR was 2 times greater than the incidence in placebo-treated patients.

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 post-approval use of alprazolam and/or alprazolam XR.
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, jaundice Investigations: Liver enzyme elevations Psychiatric disorders: Hypomania, mania Reproductive system and breast disorders: Gynecomastia, galactorrhea, menstruation irregular Skin and subcutaneous tissue disorders: Photosensitivity reaction, angioedema, Stevens-Johnson syndrome
