Cialis (tadalafil) is a prescription medication used to treat erectile dysfunction (ED) and benign prostatic hyperplasia (BPH) in men. This phosphodiesterase type 5 (PDE5) inhibitor works by relaxing blood vessels and increasing blood flow to the penis, helping men achieve and maintain erections suitable for sexual activity. For patients seeking affordable erectile dysfunction medications, working with qualified healthcare providers ensures proper diagnosis, appropriate monitoring, and access to authentic treatments with proper safety oversight for managing this sensitive health condition effectively.
