VIAGRA can give users a bit too much lift in the bedroom — by causing flatulence.
The sex pill’s windy side-effect was among 555 reported to the medicines watchdog.
Ten fellas complained it made them lose their hearing — like Playboy boss Hugh Hefner.
His lovers Karissa and Kristina Shannon claimed he said he would rather live in silence than without sex before he died aged 91 in 2017.
One bloke’s lips started to swell after using the little blue pill, another became euphoric and seven fainted.
One man reported the bottom burps.
The pill has been linked to 32 deaths in five years.
Around 3.5 million prescriptions for Viagra, or the generic version sildenafil, are handed out annually.
Many more men buy it over the counter for about £4.
It is also given to patients with blood-pressure problems.
Suspected side effects are recorded by the Medicines and Healthcare products Regulatory Agency under its “yellow card” scheme.
The system allows patients and doctors to file a report if they believe a drug has triggered a bad reaction.
The MHRA said all medicines have side-effects and carry some risk but said many events may be coincidental.
Manufacturers Pfizer said most of the side-effects were reported by patients who took sildenafil for high-blood pressure.
A spokesman added: “Since its introduction in 1998 sildenafil has been used by more than 37 million men.
“Its safety has been well established through extensive post-marketing surveillance.”
