17 PATIENT COUNSELING INFORMATION
See FDA-approved Medication Guide.

17.1 Bronchospasm
DALIRESP is not a bronchodilator and should not be used for the relief of acute bronchospasm. [see Warnings and Precautions (5.1)].

17.2 Psychiatric Events including Suicidality
Treatment with DALIRESP is associated with an increase in psychiatric adverse reactions. In clinical trials, 5.9% (263) of patients treated with DALIRESP 500 mcg daily reported psychiatric adverse reactions compared to 3.3% (137) treated with placebo. The most commonly reported psychiatric adverse events were insomnia, anxiety, and depression which were reported at higher rates in those treated with DALIRESP 500 mcg (2.4%, 1.4%, and 1.2% for DALIRESP versus 1.0%, 0.9%, and 0.9% for placebo, respectively). Instances of suicidal ideation and behavior, including completed suicide, have been observed in clinical trials. Three patients experienced suicide-related adverse reactions (one completed suicide and two suicide attempts) while receiving DALIRESP compared to one patient (suicidal ideation) who received placebo.

Before using DALIRESP in patients with a history of depression and/or suicidal thoughts or behavior, prescribers should carefully weigh the risks and benefits of treatment with DALIRESP in such patients. Patients, their caregivers, and families should be advised of the need to be alert for the emergence or worsening of insomnia, anxiety, depression, suicidal thoughts or other mood changes, and if such changes occur to contact their healthcare provider. Prescribers should carefully eva luate the risks and benefits of continuing treatment with DALIRESP if such events occur [see Warnings and Precautions (5.2)].

17.3 Weight Decrease
Weight loss was a common adverse reaction in DALIRESP clinical trials and was reported in 7.5% (331) of patients treated with DALIRESP 500 mcg once daily compared to 2.1% (89) treated with placebo. In two placebo-controlled clinical trials of one year duration in which weight was prospectively assessed, 20% of patients receiving roflumilast experienced moderate weight loss (defined as between 5-10% of body weight) compared to 7% of patients who received placebo and 7% of patients who received roflumilast compared to 2% of patients receiving placebo experienced severe (>10% body weight) weight loss. During follow-up after treatment discontinuation, the majority of patients with weight loss regained some of the weight they had lost while receiving DALIRESP. Patients treated with DALIRESP should have their weight monitored regularly. If unexplained or clinically significant weight loss occurs, weight loss should be eva luated, and discontinuation of DALIRESP should be considered [see Warnings and Precautions (5.3)].

The administration of the cytochrome P450 enzyme inducer rifampicin resulted in a reduction in exposure which may result in a decre
