VIAGRA was shown to potentiate the hypotensive effect of nitrates (4.1, 7.1, 12.2)Known hypersensitivity to sildenafil or any component of tablet (4.2)Administration with guanylate cyclase (GC) stimulators, such as riociguat (4.3)WARNINGS AND PRECAUTIONSPatients should not use VIAGRA if sexual activity is inadvisable due to cardiovascular status (5.1)Patients should seek emergency treatment if an erection lasts >4 hours. Use VIAGRA with caution in patients predisposed to priapism (5.2)Patients should stop VIAGRA and seek medical care if a sudden loss of vision occurs in one or both eyes, which could be a sign of non arteritic anterior ischemic optic neuropathy (NAION). VIAGRA should be used with caution, and only when the anticipated benefits outweigh the risks, in patients with a history of NAION. Patients with a "crowded" optic disc pink viagra may also be at an increased risk of NAION.

Factor	Impact on Viagra Efficacy	Recommendations
Alcohol consumption	Decreases effectiveness	Limit intake before use
Smoking	Impairs vascular response	Quit smoking for better results
Diet	High-fat meals delay absorption	Take on an empty stomach or low-fat meal
Exercise	May improve response	Regular activity can help overall health

(5.3)Patients should stop VIAGRA and seek prompt medical attention in the event of sudden decrease or loss of hearing (5.4)Caution is advised when VIAGRA is co-administered with alpha-blockers or anti-hypertensives. Concomitant use may lead to hypotension (5.5)Decreased blood pressure, syncope, and prolonged erection may occur at higher sildenafil exposures. In patients taking strong CYP inhibitors, such as ritonavir, sildenafil exposure is increased.

Use VIAGRA with caution in patients predisposed to priapism (5.2) Patients should stop VIAGRA and seek medical care if a sudden loss of vision occurs in one or both eyes, which could be a sign of non arteritic anterior ischemic optic neuropathy (NAION). Patients should stop VIAGRA and seek prompt medical attention in the event of sudden decrease or loss of hearing (5.4) Caution is advised when VIAGRA is co-administered with alpha-blockers or anti-hypertensives. Concomitant use may lead to hypotension (5.5) Decreased blood pressure, syncope, and prolonged erection may occur at higher sildenafil exposures. Decrease in VIAGRA dosage is recommended (2.4, 5.6) Most common adverse reactions (≥ 2%) include headache, flushing, dyspepsia, abnormal vision, nasal congestion, back pain, myalgia, nausea, dizziness and rash (6.1) To report SUSPECTED ADVERSE REACTIONS, contact Pfizer at 1-800-438-1985 or FDA at 1-800-FDA-1088 or VIAGRA can potentiate the hypotensive effects of nitrates, alpha blockers, and anti-hypertensives (4.1, 5.5, 7.1, 7.2, 7.3, 12.2) With concomitant use of alpha blockers, initiate VIAGRA at 25 mg dose (2.3) CYP3A4 inhibitors (e.g., ritonavir, ketoconazole, itraconazole, erythromycin): Increase VIAGRA exposure (2.4, 7.4, 12.3) See 17 for PATIENT COUNSELING INFORMATION and FDA-approved patient labeling.

How to take Viagra safely

However, VIAGRA may be taken anywhere from 30 minutes to 4 hours before sexual activity.The maximum recommended dosing frequency is once per day.Based on effectiveness and toleration, the dose may be increased to a maximum recommended dose of 100 mg or decreased to 25 mg.2.3 Dosage Adjustments in Specific SituationsVIAGRA was shown to potentiate the hypotensive effects of nitrates and its administration in patients who use nitric oxide donors such as organic nitrates or organic nitrites in any form is therefore contraindicated [see Contraindications (4.1), Drug Interactions (7.1), and Clinical Pharmacology (12.2)].When VIAGRA is co-administered with an alpha-blocker, patients should be stable on alpha-blocker therapy prior to initiating VIAGRA treatment and VIAGRA should be initiated at 25 mg [see Warnings and Precautions (5.5), Drug Interactions (7.2), and Clinical Pharmacology (12.2)].2.4 Dosage Adjustments Due to Drug InteractionsRitonavirThe recommended dose for ritonavir-treated patients is 25 mg prior to sexual activity and the recommended maximum dose is 25 mg within a 48 hour period because concomitant administration increased the blood levels of sildenafil by 11-fold [see Warnings and Precautions (5.6), Drug Interactions (7.4), and Clinical Pharmacology (12.3)].CYP3A4 InhibitorsConsider a starting dose of 25 mg in patients treated with strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, or saquinavir) or erythromycin. Clinical data have shown that co-administration with saquinavir or erythromycin increased plasma levels of sildenafil by about 3 fold [see Drug Interactions (7.4) and Clinical Pharmacology (12.3)].2.5 Dosage Adjustments in Special PopulationsConsider 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 (8.5, 8.6, 8.7) and Clinical Pharmacology (12.3)]. For most patients, the recommended dose is 50 mg taken, as needed, approximately 1 hour before sexual activity. 4 CONTRAINDICATIONS 4.1 NitratesConsistent with its known effects on the nitric oxide/cGMP pathway [see Clinical Pharmacology (12.1, 12.2)], VIAGRA was shown to potentiate the hypotensive effects of nitrates, and its administration to patients who are using nitric oxide donors such as organic nitrates or organic nitrites in any form either regularly and/or intermittently is therefore contraindicated.After patients have taken VIAGRA, it is unknown when nitrates, if necessary, can be safely administered. Although plasma levels of sildenafil at 24 hours post dose are much lower than at peak concentration, it is unknown whether nitrates can be safely co-administered at this time point [see Dosage and Administration (2.3), Drug Interactions (7.1), and Clinical Pharmacology (12.2)].4.2 Hypersensitivity ReactionsVIAGRA is contraindicated in patients with a known hypersensitivity to sildenafil, as contained in VIAGRA and REVATIO, or any component of the tablet.
