Can you take Duvelisib with Proscar?

Duvelisib has a major potential interaction with Infection.

Any infection should be treated prior to initiation of treatment with duvelisib. Serious, including fatal infections have occurred in patients receiving treatment with this drug. The most common serious infections were pneumonia (including fatal pneumocystis jirovecii pneumonia, PJP), sepsis, and lower respiratory infections. Advise patients to report any new or worsening signs and symptoms of infection. In some cases, treatment might need to be suspended while the infection is treated. Prophylaxis for PJP should be provided during treatment, and in some cases also prophylactic antivirals should be considered in patients with history of CMV infection to avoid CMV reactivation.

Duvelisib has a moderate potential interaction with Liver Disease.

Bilirubin and ALT and/or AST elevation has been reported in patients receiving duvelisib. Monitor hepatic function in all patients during treatment with duvelisib. Caution and close monitoring is advised in patients with hepatic impairment.

The finasteride in Proscar has a moderate potential interaction with Liver Disease.

Finasteride and dutasteride are extensively metabolized by the liver. Therapy with these drugs should be administered cautiously in patients with liver disease as exposure could be higher.

Duvelisib has a moderate potential interaction with Neutropenia.

Caution and close monitoring is advised when starting treatment in patients with neutropenia. Grade 3 or 4 neutropenia has been reported in 42% of patients receiving treatment. Monitor neutrophil counts at least every 2 weeks for the first 2 months of duvelisib therapy, and at least weekly in patients with neutrophil counts < 1.0 Gi/L (Grade 3-4). Withhold treatment with duvelisib in patients presenting with neutrophil counts < 0.5 Gi/L (Grade 4). Monitor until ANC is > 0.5 Gi/L, and then resume duvelisib at same dose for the first occurrence or a reduced dose for subsequent occurrence.

Duvelisib has a major potential interaction with Noninfectious Colitis.

Serious, including fatal diarrhea or colitis has been reported in 18% of patients receiving treatment with duvelisib. Patients with history of colitis should be monitored closely for any signs or symptoms. Advise patients to report any new or worsening diarrhea. Patients presenting with abdominal pain, stool with mucus or blood, change in bowel habits, peritoneal signs, or with diarrhea that is noninfectious should be followed closely and supportive therapy should be initiated based on severity (antidiarrheal agents, to enteric acting or systemic steroids if needed). A diagnostic work- up to determine etiology, including colonoscopy, should be performed. Monitor at least weekly. Upon resolution of the diarrhea or colitis, treatment can be restarted at a reduced dose. Treatment should be discontinued for recurrent Grade 3 diarrhea or recurrent colitis of any grade.

The finasteride in Proscar has a moderate potential interaction with Urinary Tract Obstruction.

Patients with large residual urinary volume and/or severely diminished urinary flow should be carefully monitored for obstructive uropathy. These patients may not be candidates for finasteride therapy.
