WARNINGS AND PRECAUTIONS

amiloridetadalafil increases effects of amiloride by pharmacodynamic synergism.

• The mechanism for treating BPH is separate from its effect on blood vessels.
• For BPH, it works by inhibiting PDE5 in the prostate, bladder, and urethra.
• This leads to smooth muscle relaxation in the lower urinary tract.
• Patients may experience improved urinary frequency, urgency, and flow.
• It is not a treatment for prostate cancer, though symptoms can overlap.
• A prostate-specific antigen (PSA) test is often done before and during treatment.
• Tadalafil can cause a slight decrease in measured PSA levels.
• Your doctor needs to be aware you are taking it when interpreting PSA results.
• It represents a non-surgical option for managing moderate BPH symptoms.
• Surgical options remain for cases where medication is not effective enough.
