Tadalis SX 20 mg is a tadalafil-based medicine used to treat erectile dysfunction in men. It works by improving blood flow to the penis during sexual stimulation, which helps support a firmer erection and can improve sexual performance. Common side effects may include headache, back pain, muscle pain, indigestion, flushing, nasal congestion, and dizziness. These effects are often mild, but serious symptoms such as chest pain, fainting, vision changes, or an erection lasting more than 4 hours need urgent medical care.
