Clinical data have shown that co-administration with saquinavir or erythromycin increased plasma levels of sildenafil by about 3 fold [see DRUG INTERACTIONS and CLINICAL PHARMACOLOGY]. Consider a starting dose of 25 mg in patients > 65 years, patients with hepatic impairment (e.g., cirrhosis), and patients with severe renal impairment (creatinine clearance <30 mL/minute) because administration of VIAGRA in these patients resulted in higher plasma levels of sildenafil [see Use In Specific Populations and CLINICAL PHARMACOLOGY]. VIAGRA is supplied as blue, rounded diamond shaped film-coated tablets containing sildenafil citrate equivalent to 25 mg, 50 mg, or 100 mg of sildenafil.

Reported events include those with a plausible relation to drug use; omitted are minor events and reports too imprecise to be meaningful: Body as a Whole: face edema, photosensitivity reaction, shock, asthenia, pain, chills, accidental fall, abdominal pain, allergic reaction, chest pain, accidental injury. Respiratory: asthma, dyspnea, laryngitis, pharyngitis, sinusitis, bronchitis, sputum increased, cough increased. Skin and Appendages: urticaria, herpes simplex, pruritus, sweating, skin ulcer, contact dermatitis, exfoliative dermatitis.

Adjusting Your Sildenafil Dosage Over Time
Non-arteritic anterior ischemic optic neuropathy (NAION), a cause of decreased vision including permanent loss of vision, has been reported rarely post-marketing in temporal association with the use of phosphodiesterase type 5 (PDE5) inhibitors, including VIAGRA. 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 [see WARNINGS AND PRECAUTIONS and PATIENT INFORMATION]. Urogenital: prolonged erection, priapism [see WARNINGS AND PRECAUTIONS and PATIENT INFORMATION], and hematuria. Administration of VIAGRA with nitric oxide donors such as organic nitrates or organic nitrites in any form is contraindicated.
