Viagra is one of the most controversial and widely discussed pharmaceutical drugs to have hit the market in the last 30 years. Men most commonly use this to treat erectile dysfunction. However, there are men who use Viagra to prolong their erection because, as they claim, the longer you are erect, the better the sexual performance.

The U.S. Food and Drug Administration has warned the public of the serious side effects of taking Viagra such as sudden vision and hearing loss, heart attack, stroke, irregular heartbeats, and death. But what if a person has taken Viagra that is not intended for humans, what would be the consequence?

An unnamed man from Reynosa, Mexico was rushed to the hospital after complaining about a painful three-day erection. At the hospital, he admitted consuming a sexual stimulant meant for breeding bulls in hopes of having a steamy sexual encounter with his date, according to an article by Latin Times.

The man reportedly traveled from Veracruz in East Mexico to purchase a stimulant that would treat his erectile dysfunction as he wanted to have sex with a young, 30-year-old woman. However, the sexual stimulant he bought was actually a drug used by Mexican breeders to stimulate bulls for cattle reproduction.

After three days of experiencing the painful erection, the unidentified man decided to have himself checked by a medical professional at a hospital in Reynosa at the U.S.-Mexico border and see if he could undergo an urgent operation that would possibly help alleviate the erection.

In an interview, a doctor said he was hospitalized in the Specialized Hospital 20 of the city of Reynosa. "He had taken a sexual stimulant which he had bought in Veracruz, used by farmers in that region to invigorate bulls for insemination," the doctor added.

As of this writing, the results of the surgery remain unknown. If it turned out to be unsuccessful, then the likelihood is that the man's penis will no longer function for erectile purposes.

Meanwhile, the story was quick to spread like wildfire across the web, with several Twitter users posting amusing comments about the story. "Tadalifil does the same thing, ask your GP for some," one user wrote. "I'll take a whole pack, please," another user joked.

One Twitter user even made fun of British Prime Minister Boris Johnson in his tweet, saying, "Get well soon @BorisJohnson." "They could not have got the coffin lid on if he died," the user added. Some users also jokingly suggested using other types of Viagra as they made fun of the man's condition. "He should have tried the new Viagra LIGHT," one user tweeted.

Although many animal drugs start off as human medications, because there is far more money invested in human drug research, there are cases where manufacturers sometimes reformulate their drugs for sale to animal owners. This may explain why the unnamed man experienced the said side effects of Viagra pills for bulls since taking veterinary medications is not recommended for humans.
