What is Liqrev?
The incidence of epistaxis was also higher in sildenafil -treated patients with a concomitant oral vitamin K antagonist (9% versus 2% in those not treated with concomitant vitamin K antagonist).The safety of sildenafil is unknown in patients with bleeding disorders or active peptic ulceration.5.4 Visual LossWhen used to treat erectile dysfunction, non-arteritic anterior ischemic optic neuropathy (NAION), a cause of decreased vision including permanent loss of vision, has been reported post marketing in temporal association with the use of PDE-5 inhibitors, including sildenafil. Most patients had underlying anatomic or vascular risk factors for developing NAION, including low cup to disc ratio ("crowded disc").Advise patients to seek immediate medical attention in the event of a sudden loss of vision in one or both eyes while taking sildenafil.There are no controlled clinical data on the safety or efficacy of sildenafil in patients with retinitis pigmentosa, a minority of whom have genetic disorders of retinal phosphodiesterases. It is not possible to determine whether these reported events are related directly to the use of sildenafil to the patient's underlying risk factors for hearing loss, a combination of these factors, or to other factors.Advise patients to seek prompt medical attention in the event of sudden decrease or loss of hearing while taking PDE-5 inhibitors, including sildenafil.5.6 Combination with Other PDE-5 InhibitorsSildenafil is also marketed as VIAGRA®. Inform patients taking sildenafil not to take VIAGRA or other PDE-5 inhibitors.5.7 PriapismUse sildenafil with caution in patients with anatomical deformation of the penis (e.g., angulation, cavernosal fibrosis, or Peyronie's disease) or in patients who have conditions, which may predispose them to priapism (e.g., sickle cell anemia, multiple myeloma, or leukemia).
