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 incidences cited below are estimates of clinical reactions among 1,003 subjects who participated in the short term (duration of 1 to 42 days) placebo-controlled clinical trials of triazolam.

Adverse reactions leading to discontinuation in two multi-dose placebo controlled clinical trials include coordination disorders, drowsiness, grogginess, somnolence, depression, restlessness, dizziness, lightheadedness, headache, nausea, visual disturbance, nervousness, abdominal distress, bladder trouble, aching limbs, backache, and blepharitis.

Table 1 Common Adverse Drug Reactions in 1% or More of Triazolam-Treated Subjects (and Greater than Placebo) Reported in Placebo-Controlled Clinical Trials Event Triazolam (N=1,003) % Patients Reporting Placebo (N=997) % Patients Reporting Central Nervous System Drowsiness 14 6.4 Headache 9.7 8.4 Dizziness 7.8 3.1 Nervousness 5.2 4.5 Light-headedness 4.9 0.9 Coordination disorders/ataxia 4.6 0.8 Gastrointestinal Nausea/vomiting 4.6 3.7 In addition to the common reactions enumerated above in Table1, the following adverse reactions have been reported at an incidence of 0.9% to 0.5%: euphoria, tachycardia, tiredness, confusional states/memory impairment, cramps/pain, depression, and visual disturbances.

Adverse reactions reported at an incidence less than 0.5% include: constipation, taste alterations, diarrhea, dry mouth, dermatitis/allergy, dreaming/nightmares, insomnia, paresthesia, tinnitus, dysesthesia, weakness, congestion, and death from hepatic failure in a patient also receiving diuretic drugs.

6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of triazolam.

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.
