Cialis 80 mg is a high-strength erectile dysfunction medication formulated for men who do not respond well to lower doses of tadalafil. It works by relaxing blood vessels and increasing blood flow to the penile area, helping achieve and maintain a strong erection during sexual stimulation. Known for its long-lasting effect, Cialis 80 mg can remain active in the body for up to 36 hours, allowing greater flexibility and spontaneity in intimate moments. This makes it a popular option for men seeking extended performance support. The tablet is usually taken once daily or as directed by a healthcare professional, with or without food. To reduce the risk of side effects, alcohol intake should be limited. Possible side effects include headache, muscle pain, back pain, flushing, or indigestion. Cialis 80 mg should only be used under medical supervision, especially for men with heart conditions or those taking nitrate medications.
