Apcalis Oral Jelly is a tadalafil‑based oral jelly used to treat erectile dysfunction (ED) in adult men. Each sachet typically contains 20 mg of tadalafil, a phosphodiesterase‑5 (PDE‑5) inhibitor that relaxes blood vessels in the penis and increases blood flow, helping men achieve and maintain a firm erection when sexually stimulated. Common side effects include headache, flushing, nasal congestion, back or muscle pain, indigestion, and dizziness, which are usually mild and short‑lived. https://www.genericday.com/apcalis-oral-jelly.html
