Consumer:

Consumer information for this minor interaction is not currently available. Some minor drug interactions may not be clinically relevant in all patients. Minor drug interactions do not usually cause harm or require a change in therapy. However, your healthcare provider can determine if adjustments to your medications are needed.

Professional:

Study data (n=90) reported a statistically significant interaction between finasteride and terazosin affecting finasteride pharmacokinetics, but not those of terazosin. Treatment with terazosin (45 days) and finasteride (10 days) resulted in a finasteride Cmax and AUC(0-24) significantly greater than for finasteride alone. The clinical significance of this interaction remains to be determined. Earlier data (n=48) failed to reveal significant pharmacokinetic or pharmacodynamic alterations in either drug when administered concurrently. No special precautions are recommended at this time.
