Monitor blood pressure when co-administering blood pressure lowering drugs with sildenafil. Pulmonary vasodilators may significantly worsen the cardiovascular status of patients with pulmonary veno-occlusive disease (PVOD). Should signs of pulmonary edema occur when sildenafil is administered, consider the possibility of associated PVOD. The incidence of epistaxis was 13% in patients taking sildenafil with PAH secondary to CTD. 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. When 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.

Key features of Sildenafil 50mg Tablets

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. Therefore, use of sildenafil in patients with retinitis pigmentosa is not recommended.

Cases of sudden decrease or loss of hearing, which may be accompanied by tinnitus and dizziness, have been reported in temporal association with the use of PDE-5 inhibitors, including sildenafil. It is not possible to determine whether these reported events are related directly to the sildenafil 12 5 mg 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. Inform patients taking sildenafil tablets not to take VIAGRA or other PDE-5 inhibitors.

Does sildenafil interact with foods or drinks?

The safety of sildenafil is unknown in patients with bleeding disorders or active peptic ulceration.

What should I do if I accidentally use too much sildenafil?

Therefore, use of sildenafil in patients with retinitis pigmentosa is not recommended. Cases of sudden decrease or loss of hearing, which may be accompanied by tinnitus and dizziness, have been reported in temporal association with the use of PDE-5 inhibitors, including sildenafil. It is not possible to determine whether these reported events are related directly to the sildenafil 12 5 mg 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. Inform patients taking sildenafil tablets not to take VIAGRA or other PDE-5 inhibitors. Use Sildenafil tablets 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).

Article highlights

If priapism (painful erection greater than 6 hours in duration) is not treated immediately, penile tissue damage and permanent loss of potency could result.

What special precautions should I follow?

Use Sildenafil tablets 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). If priapism (painful erection greater than 6 hours in duration) is not treated immediately, penile tissue damage and permanent loss of potency could result. In a small, prematurely terminated study of patients with pulmonary hypertension (PH) secondary to sickle cell disease, vaso-occlusive crises requiring hospitalization were more commonly reported by patients who received sildenafil than by those randomized to placebo. 6 ADVERSE REACTIONS The following serious adverse events are discussed elsewhere in the labeling:Hypotension [see Warnings and Precautions (5.1)]Vision Loss [see Warnings and Precautions (5.4)]Hearing Loss [see Warnings and Precautions (5.5)]Priapism [see Warnings and Precautions (5.7)]Vaso-occlusive Crisis in Patients with Pulmonary Hypertension Secondary to Sickle Cell Disease [see Warnings and Precautions (5.8)]6.1 Clinical Trials ExperienceBecause clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the sildenafil citrate 120 mg clinical trials of another drug and may not reflect the rates observed in practice.In a 12-week, placebo-controlled clinical study and an open-label extension study (SUPER-1) in 277 sildenafil-treated adults with PAH (WHO Group I) [see Clinical Studies (14)] the adverse reactions that were reported by at least 10% of sildenafil-treated patients in any dosing group, and were more frequent in Sildenafil-treated patients than in placebo-treated patients are shown in Table 1. Adverse reactions were generally transient and mild to moderate in nature.

5.2 Prolonged Erection and Priapism

Many of these events were reported to occur during or shortly after sexual activity, and a few were reported to occur shortly after the use of sildenafil without sexual activity. Others were reported to have occurred hours to days after use concurrent with sexual activity.
