Man coughs up blood for 3 days after rare reaction to Viagra

A man in his 70s ended up with more than he bargained for after a dose of an impotency medication left him coughing up blood for three days.

Medics who documented the case said there have only been six other reported incidents of this type of reaction in patients taking sildenafil, most commonly known by the brand Viagra.

The man, who wasn't named in the medical case report, started coughing up blood shortly after taking sildenafil — which is used by millions of British men.

Over the next three, the report states that he hacked up an estimated 50ml of blood, equivalent to just over a shot glass's worth.

Seeking help from doctors he told medics that he had suffered a similar episode two weeks prior, again after taking the little blue pill.

Doctors undertook a thorough examination of the man, including inspecting his throat and nasal passages, and a CT scan of his chest and found no underlying condition that could have caused the bleeding.

This, and 카마그라구매 the fact the man's symptoms stopped after he ceased taking sildenafil led them to conclude the impotency drug was the most likely culprit.

'The precise timing of the episodes aligning with the intake and cessation of sildenafil, 카마그라구매 along with no abnormal laboratory results or treatment modifications, suggests a potential association between sildenafil intake and the episodes,' they wrote.

'Notably, no further episodes have occurred since the discontinuation of sildenafil.'

The patient reportedly suffered no more episodes of haemoptysis, the medical term for 시알리스처??(C) coughing up blood, after a year of follow-up.

Medics, who detailed the patient's experience in the British Medical Journal, said there have only been six other cases of sildenafil-related haemoptysis recorded in medical literature.

Considering the drug is taken by millions of patients worldwide every year, this makes it an incredibly rare and poorly understood reaction.

The authors of the case noted there were factors in their patient's medical history that could explain why the rare reaction occurred.

He was suffering from both kidney problemsand was taking another drug called rivaroxaban, an anticoagulant that thins the blood.

These factors could have combined with sildenafil, which works by temporarily increasing blood flow to the penis, to cause bleeding, they said, though they added this was just a theory. 

'Decreased renal function may affect the metabolism of sildenafil and rivaroxaban, which may explain the haemoptysis due to their increased effects of vasodilation [dilation of blood vessels] and anticoagulation, respectively,' they said.

They concluded that their case study demonstrated the need for monitoring of patients taking sildenafil whilst living with serious health conditions and taking other medications.

The authors added: 'Further studies are needed to clarify the precise mechanism that causes sildenafil-induced haemoptysis.'

Where exactly the patient was treated wasn't detailed in the case report. 




A total of 4.57million prescriptions for sildenafil, more commonly known by the brand name Viagra, and other types of impotency drugs sold under the brand 정품비아그라 names Cialis and Levitra, were dished out by the health service in 2023

It comes as data suggests millions of British men are now taking the libido boosting drug.

A total of 3million prescriptions of sildenafil for erectile dysfunction were dished out by the NHS in 2023 alone.

This doesn't account for many other Brits buying it over the counter privately from high street or online pharmacies, with some options costing mere pennies per pill.
