Hanoi - A Vietnamese man who took a fake tablet of the impotence drug Viagra was admitted to hospital after his erection lasted two days, doctors said Thursday.

The 47-year-old man was admitted Sunday to Binh Dan Hospital in Ho Chi Minh City from nearby Vinh Long province, two days after taking the Chinese-made tablet, said a doctor from the hospital where he was treated.

The man bought the pill from an acquaintance for less than two dollars (R12) last Friday and took it that evening. The man did not have intercourse after taking the pill, but could not get rid of the erection, said the doctor who declined to be named.
