Alprazolam C-Iv Side Effects

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 (5.6)] Neonatal Sedation and Withdrawal Syndrome [see WARNINGS AND PRECAUTIONS (5.8)] Risks in Patients with Impaired Respiratory Function [see WARNINGS AND PRECAUTIONS (5.9)] 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 alprazolam 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 alprazolam dosages up to 10 mg per day for panic disorder, with or without agoraphobia (Table 2).

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 alprazolam, discontinuation-emergent symptoms which occurred at a rate of over 5% in patients treated with alprazolam and at a greater rate than the placebo-treated group are shown in Table

Table 3: Discontinuation-Emergent Symptom Incidence Reported in ≥5% of Alprazolam-treated Patients and > Placebo-treated Patients n=number of patients.

Alprazolam-treated Patients n=641 Nervous system disorders Insomnia Light-headedness Abnormal involuntary movement Headache Muscular twitching Impaired coordination Muscle tone disorders Weakness 29.5% 19.3% 17.3% 17.0% 6.9% 6.6% 5.9% 5.8% Psychiatric disorders Anxiety Fatigue and Tiredness Irritability Cognitive disorder Memory impairment Depression Confusional state 19.2% 18.4% 10.5% 10.3% 5.5% 5.1% 5.0% Gastrointestinal disorders Nausea/Vomiting Diarrhea Decreased salivation 16.5% 13.6% 10.6% Metabolism and nutrition disorders Weight loss Decreased appetite 13.3% 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 alprazolam [see WARNING AND PRECAUTIONS (5.2) and DRUG ABUSE AND DEPENDENCE (9.3)].

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.
