Caverta 100 mg contains sildenafil, a PDE-5 inhibitor used to treat erectile dysfunction (ED). By improving blood flow to the penis during sexual stimulation, sildenafil can help men achieve and maintain firmer erections. Better erection quality may indirectly improve sexual confidence, particularly when worries about losing an erection contribute to performance anxiety. Clinical studies have found significant improvements in confidence, self-esteem, and relationship satisfaction among men with ED treated with sildenafil.
