Tadarise tablets are used to treat erectile dysfunction (impotence) in men, which is described as the inability to obtain or sustain a hard erect penis appropriate for sexual activity due to inadequate blood flow. Tadarise tablets work by relaxing the blood vessels in the penis, allowing more blood to circulate and producing an erection, which is a normal reaction to sexual stimulation. Tadarise tablets, on the other hand, will only work if you are sexually aroused.
