Apcalis (Tadalafil) is used to treat male sexual function problems (impotence or erectile dysfunction-ED). Tadalafil belongs to a group of medicines called phosphodiesterase 5 (PDE5) inhibitors. In combination with sexual stimulation, tadalafil works by increasing blood flow to the penis to help a man get and keep an erection. Tadalafil is also used to treat the symptoms of an enlarged prostate (benign prostatic hyperplasia-BPH).
How to use: Take one tablet as needed, usually at least 30 minutes before sexual activity. Tadalafil’s effect on sexual ability may last up to 36 hours so do not take more than one tablet a day.
To treat the symptoms of BPH, take this medication as directed by your doctor, usually once a day. If you are taking tadalafil to treat both ED and BPH, take it as directed by your doctor, usually once a day. You may attempt sexual activity at any time between your doses.
