The FDA has since clarified its recommendation stating that there may be patients in which the benefits of sildenafil therapy outweigh the risks, such as when other treatment options are limited and when close monitoring is available, and advises health care providers to weigh the risk-benefit profile for individual patients when deciding whether to initiate sildenafil. In two of the six subjects, prolonged clinical effects of sildenafil were noted for 72 hours after a single dose of sildenafil.

In many cases, medical follow-up information was limited. Lesinurad; Allopurinol: (Moderate) Lesinurad may decrease the systemic exposure and therapeutic efficacy of sildenafil; monitor for potential reduction in efficacy. Serious cardiovascular events, including myocardial infarction, sudden cardiac death, ventricular arrhythmia, cerebrovascular haemorrhage, transient ischaemic attack and hypertension have been reported post-marketing in temporal association with the use of Viagra. Ribociclib is a strong CYP3A4 inhibitor and sildenafil is a sensitive CYP3A4 substrate.
