Tadalista is primarily used to treat erectile dysfunction (ED) in men. It contains tadalafil, which helps increase blood flow to the penis, facilitating an erection when sexually stimulated. Tadalista may also be used to treat symptoms of benign prostatic hyperplasia (BPH), such as difficulty in urination due to an enlarged prostate. Always consult a healthcare professional for personalized advice and to ensure it's suitable for you.
