Tadarise 5 mg contains Tadalafil, a medication used for erectile dysfunction (ED). While it is generally well-tolerated, some men may experience mild side effects. Common side effects include headache, dizziness, flushing, nasal congestion, upset stomach, muscle or back pain, and mild visual changes. Tadarise 5 mg is already a low daily dose, which helps minimize side effects. Taking it consistently at the same time each day allows the body to adjust gradually.
