Transient haemoptysis after taking sildenafil

We report a case of a man in his 70s who developed haemoptysis 3 days after commencing sildenafil. Before postulating a potential connection between sildenafil use and haemoptysis, it is important to rule out potential other causative factors and comorbidities. The patient suffers from multiple medical conditions and takes various medications. On examination, no abnormalities were discovered. There were no recent significant changes in his bloodwork. Cessation of sildenafil coincided with spontaneous symptom resolution. Chest CT was performed, and no abnormalities were reported. Pseudohaemoptysis or malignancy may be the main differential diagnoses of haemoptysis in elderly patients with multiple comorbidities. Concurrent anticoagulation of the patient may predispose to haemoptysis and is likely to be of greater clinical concern.
