10. OVERDOSAGE

Monitor blood pressure when co-administering blood pressure lowering drugs with sildenafil tablets.5.3 Worsening Pulmonary Vascular Occlusive DiseasePulmonary vasodilators may significantly worsen the cardiovascular status of patients with pulmonary veno-occlusive disease (PVOD).

• Common side effects of sildenafil include headaches, flushing, and nasal congestion.
• Serious side effects are rare but require immediate medical attention.
• Patients should report any adverse reactions to their healthcare provider.

Since there are no clinical data on administration of sildenafil tablets to patients with veno-occlusive disease, administration of sildenafil tablets to such patients is not recommended. Should signs of pulmonary edema occur when sildenafil tablets are administered, consider the possibility of associated PVOD.5.4 EpistaxisThe incidence of epistaxis was 13% in patients taking sildenafil tablets with PAH secondary to CTD. This effect was not seen in idiopathic PAH (sildenafil tablets 3%, placebo 2%) patients. The incidence of epistaxis was also higher in sildenafil tablets-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 tablets is unknown in patients with bleeding disorders or active peptic ulceration.5.5 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 postmarketing in temporal association with the use of phosphodiesterase type 5 (PDE-5) inhibitors, including sildenafil. Most, but not all, of these patients had underlying anatomic or vascular risk factors for developing NAION, including but not necessarily limited to: low cup to disc ratio ("crowded disc"), age over 50, diabetes, hypertension, coronary artery disease, hyperlipidemia and smoking.

Based on published literature, the annual incidence of NAION is 2.5–11.8 cases per 100,000 males aged ≥ 50 per year in the general population.An observational case-crossover study evaluated the risk of NAION when PDE-5 inhibitor use, as a class, occurred immediately before NAION onset (within 5 half-lives), compared to PDE-5 inhibitor use in a prior time period. Other risk factors for NAION, such as the presence of “crowded” optic disc, may have contributed to the occurrence of NAION in these studies.Neither the rare postmarketing reports, nor the association of PDE-5 inhibitor use and NAION in the observational studies, substantiate a causal relationship between PDE-5 inhibitor use and NAION [see Adverse Reactions (6.2)].Advise patients to seek immediate medical attention in the event of a sudden loss of vision in one or both eyes while taking PDE-5 inhibitors, including sildenafil tablets. Physicians should also discuss the increased risk of NAION with patients who have already experienced NAION in one eye, including whether such individuals could be adversely affected by use of vasodilators, such as PDE-5 inhibitors.There are no controlled clinical data on the safety or efficacy of sildenafil tablets in patients with retinitis pigmentosa, a minority whom have genetic disorders of retinal phosphodiesterases. Prescribe sildenafil tablets with caution in these patients.5.6 Hearing LossCases 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 tablets. It is not possible to determine whether these reported events are related directly to the use of Sildenafil tablets, 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 tablets.5.7 Combination with other PDE-5 inhibitorsSildenafil is also marketed as VIAGRA ®;.

• Sildenafil 20 mg is a prescription medication used for erectile dysfunction.
• It helps increase blood flow to the penis during sexual activity.
• Typically prescribed for men with ED to improve sexual performance.

Inform patients taking sildenafil tablets not to take VIAGRA or other PDE-5 inhibitors.5.8 PriapismUse 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.5.9 Vaso-occlusive Crisis in Patients with Pulmonary Hypertension Secondary to Sickle Cell AnemiaIn 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 tablets than by those randomized to placebo. The effectiveness and safety of sildenafil tablets in the treatment of PAH secondary to sickle cell anemia has not been established. In a long-term trial in pediatric patients with PAH, an increase in mortality with increasing sildenafil tablets dose was observed. [see Use in Specific Populations (8.4)].

Sildenafil tablets has vasodilatory properties, sildenafil 200 mg resulting in mild and transient decreases in blood pressure. Monitor blood pressure when co-administering blood pressure lowering drugs with sildenafil tablets.

[see Clinical Studies (14)].The overall frequency of discontinuation in sildenafil tablets-treated patients on 20 mg three times a day was 3% and was the same for the placebo group.In Study 1, the adverse reactions that were reported by at least 3% of sildenafil tablets-treated patients (20 mg three times a day) and were more frequent in sildenafil tablets-treated patients than in placebo-treated patients are shown in Table 1. Adverse reactions were generally transient and mild to moderate in nature.At doses higher than the recommended 20 mg three times a day, there was a greater incidence of some adverse reactions including flushing, diarrhea, myalgia and visual disturbances. The incidence of epistaxis was also higher in sildenafil tablets-treated patients with a concomitant oral vitamin K antagonist (9% versus 2% in those not treated with concomitant vitamin K antagonist).
