tadalafil tadarise 40 mg is an oral medication that works as an erection aid. It belongs to a group of medicines called phosphodiesterase (PDE) inhibitors, which increase blood flow to the penis. This increases the likelihood of a man having an erection and achieving a strong, hard erection that lasts. The medicine is used to treat erectile dysfunction and symptoms of benign prostatic hyperplasia (BPH). It helps men who suffer from these conditions achieve a stronger, firmer erection. You should always take this medication exactly as prescribed by your doctor. Using this medication incorrectly may cause side effects, such as increased heart rate or lower blood pressure. You should also avoid drinking alcohol while using this drug as it can decrease your ability to get an erection.
