Tadalafil (sold in brands like Tadalista 60) is primarily used to treat: 1. Erectile dysfunction (ED) It helps men achieve and maintain an erection by improving blood flow to the ***** during ***** stimulation. It does not increase ***** desire and only works with arousal. 2. Benign prostatic hyperplasia (BPH) (in some cases) It can help relieve urinary symptoms caused by an enlarged prostate, such as difficulty starting urination, weak stream, or frequent urination. About Tadalista 60 mg specifically: Tadalista 60 mg is a very high-strength form of tadalafil. Standard prescribed doses are usually much lower (2.5 mg, 5 mg, 10 mg, or 20 mg). A 60 mg dose is not commonly recommended in clinical guidelines, and it may increase the risk of side effects like headache, flushing, back pain, muscle aches, low blood pressure, and dizziness. Because tadalafil stays in the body longer than many ED medicines (up to ~36 hours in lower doses), high doses can make side effects last longer as well.
