How to take Generic Viagra (Sildenafil Citrate)?
Take Generic Viagra exactly as directed by your doctor. Take each dose with a
full glass of water.
DOSAGE:
- If you have prostate problems or high blood pressure for which you take medicines called alpha-blockers, your doctor may start you on a lower dose of Generic Viagra.
- For most patients, the recommended dose is 50 mg taken, as needed, approximately 1 hour before sexual activity. However, Generic Viagra may be taken anywhere from 4 hours to 0.5 hour before sexual activity. Based on effectiveness and toleration, the dose may be increased to a maximum recommended dose of 100 mg or decreased to 25 mg. The maximum recommended dosing frequency is once per day.
If OVERDOSE
In studies with healthy volunteers of single doses up to 800 mg, adverse events were similar to those seen at lower doses but incidence rates were increased. In cases of overdose, standard supportive measures should be adopted as required. Renal dialysis is not expected to accelerate clearance as sildenafil is highly bound to plasma proteins and it is not eliminated in the urine.
What to do if I miss a dose?
Generic Viagra is used as needed, so you are not likely to miss a dose.
Who should not take Viagra (Sildenafil Citrate)?
- Generic Viagra is not indicated for use in newborns, children, or women.
- If you take any medicines that have nitrates in them (like nitroglycerin for chest pain)—every day or even once in a while—you should NOT take Generic Viagra.
- Generic Viagra has systemic vasodilatory properties and may augment the blood pressure lowering effect of other anti-hypertensive medications
- There is no controlled clinical data on the safety or efficacy of Generic Viagra in the following groups; if prescribed, this should be done with caution.
IMPORTANT PRESCRIBING INFORMATION
- Patients who have suffered a myocardial infarction, stroke, or life-threatening arrhythmia within the last 6 months
- Patients with resting hypotension (BP<90/50/) or hypertension (BP>170/100)
- Patients with cardiac failure or coronary artery disease causing unstable angina
- Patients with retinitis pigmentosa (a minority of these patients have genetic disorders of retinal phosphodiesterasese).
Generic Viagra should be used with caution in patients with anatomical deformation of the penis (such as angulation, cavernosal fibrosis or Peyronie’s disease), or in patients who have conditions which may predispose them to priapism (such as sickle cell anemia, multiple myeloma, or leukemia).
What side effects may occur?
The most common side effects of Generic Viagra are headache, facial flushing, dyspepsia, nasal congestion, urinary tract infection, abnormal vision, diarrhea, dizziness, rash and upset stomach. If you observed that you have some of these effects refrain from further sexual activity and notify your doctor. Less commonly, bluish vision, blurred vision, or sensitivity to light may briefly occur. If you experience sudden decrease or loss of vision, stop taking Generic Viagra, and call a doctor right away.
Generic Viagra (Sildenafil Citrate) Drug Interactions
Caution is advised when Phosphodiesterase Type 5 (PDE5) inhibitors are co-administered with alpha-blockers. PDE5 inhibitors, including VIAGRA, and alpha-adrenergic blocking agents are both vasodilators with blood pressure lowering effects. When vasodilators are used in combination, an additive effect on blood pressure may be anticipated. In some patients, concomitant use of these two drug classes can lower blood pressure significantly leading to symptomatic hypotension (e.g. dizziness, lightheadedness, fainting).
The safety and efficacy of combinations of Generic Viagra with other treatments for erectile dysfunction have not been studied. Therefore, the use of such combinations is not recommended. In humans, Generic Viagra has no effect on bleeding time when taken alone or with aspirin. In vitro studies with human platelets indicate that sildenafil potentiates the antiaggregatory effect of sodium nitroprusside (a nitric oxide donor). The combination of heparin and Generic Viagra had an additive effect on bleeding time in the anesthetized rabbit, but this interaction has not been studied in humans.
