Item info:
VIAGRA (sildenafil citrate) is a prescription drug intended for use by men who have erectile dysfunction (impotence). It helps fill the penis with enough blood to cause an erection. By itself, VIAGRA can not help men get and keep an erection; it can only work when men are sexually excited (stimulated).
VIAGRA is for men only. VIAGRA is not indicated for use in women.
Not to confuse with VIAGRA, REVATIO (another brand in the drug class sildenafil) is used to treat pulmonary arterial hypertension and improve exercise capacity in men and women.
VIAGRA is available in tablet form. You can buy VIAGRA online through online pharmacies or online ordering systems like Euromedonline. If you need a prescription, you can fill out our prescription request form and a US-licensed physician will issue you with one.
Contraindications:
Do not take VIAGRA without informing your doctor of your sensitivity to its formulation: (active) sildenafil citrate; (inactive) microcrystalline cellulose, anhydrous dibasic calcium phosphate, croscarmellose sodium, magnesium stearate, hydroxypropyl methylcellulose, titanium dioxide, lactose, triacetin, and FD & C Blue #2 aluminum lake.
Before taking VIAGRA (sildenafil), tell your doctor if you have heart problems. Your heart may not be healthy enough to handle the extra strain of sexual activity.
Other conditions your doctor also needs to know include:
The existence of these conditions may require your doctor to prohibit, make a dosage adjustment or call for special tests before or during intake.
Interactions:
Do not take VIAGRA without first talking to your doctor if you are taking other prescription or over-the-counter medicines; including vitamins, minerals, and herbal supplements.
Do not take VIAGRA (sildenafil) if you are taking medicines that contain nitrates of any kind, including nitroglycerin and isosorbide mononitrate. This will cause your blood pressure to suddenly drop and become life threatening.
Before taking VIAGRA (sildenafil), tell your doctor if you are using:
VIAGRA is known to cause mild and temporary lowering of your blood pressure. Other common side effects include headache, flushing of the face, and upset stomach.
Less common and more temporary side effects affect vision, including temporary changes in color vision, sensitivity to light, and blurring.
Stop using VIAGRA and call your doctor at once if you feel pain or tight feeling in your chest or irregular heartbeat.
Prolonged erection (more than four hours) can permanently damage your penis. Call a doctor immediately.
If you develop allergic-type reactions, stop taking VIAGRA and seek immediate medical attention.
Side effects other than those identified here may also occur. Talk to your doctor about any side effect that seems unusual or bothersome
Dosage:

You may also call 1.866.279.1400 for 24/7 customer support.
Do not take VIAGRA more than once per day. Take VIAGRA about one hour before sexual activity. If you have consumed a high-fat meal, it may take a while longer to take effect.
