Generic Viagra Sildenafil

Generic Viagra Sildenafil

How does generic Viagra work?

Sildenafil (“generic Viagra”) works in exactly the same way as Viagra. They both belong to a group of medicines called PDE-5 inhibitors, which relax the blood vessels that supply the penis. This allows more blood to flow to the penis when aroused, enabling an erection.

Both Sildenafil and Viagra are taken in the form of tablets, on an empty stomach about an hour before sex. They are not aphrodisiacs, so you will still need to be sexually aroused for them to work. You should also avoid drinking alcohol before taking Viagra or Sildenafil as this may limit its effectiveness. Taken correctly, both Viagra and generic Viagra should last for around 4 to 6 hours.

Don’t be disappointed if you don’t see the results you hoped for the first time that you take generic Viagra. You should persevere, as it may take up to eight attempts to work for you, alternatively your doctor may recommend a different dosage.

Viagra Dosage Information

viagra may be taken with or without food.

The recommended dose for most patients is a 50mg dose approximately 1 hour before sexual activity. Some will find they can take it as soon as 30 minutes before sex and have it take effect in time, while others will find they are best taking it up to 4 hours before sex.

The dosage could be upped to 100mg or decreased to 25mg depending on how your respond to the medications and based on your doctor’s recommendations.

The maximum dose is once a day, and more detailed information regarding dosage will be found in the printed guidelines for taking the medication included with your purchase when you order Viagra online or pick up your prescription in the pharmacy.

Appearance and Form

In addition to retaining the Viagra name, Pfizer also retained the trademark on the appearance of the drug; the blue diamond shape.

Subsequently, manufacturers of Sildenafil are unable to produce the drug with a similar appearance.

Usually, Sildenafil will be issued simply as a regular-shaped blue or white tablet; however in 2012, Nipatra, a chewable version of sildenafil was released by Mercury Pharma.

Whereas Viagra tablets have ‘VGR’ and the dosage amount inscribed on them, Sildenafil will normally have ‘SL’, followed by the dosage.

Viagra Warnings

Some medicines are not safe to take with Viagra. Specifically, Viagra shouldn’t be used in combination with a nitrate drug for treating chest pain or heart problems. This includes nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, amyl nitrate, or nitrite "poppers."

Taking Viagra with a nitrate drug can cause a sudden and dangerous drop in blood pressure.

Also, you shouldn’t use the medicine for pulmonary hypertension Adempas (riociguat) if you’re taking Viagra.

  • Before you start on Viagra, tell your doctor if you have or have ever had:
  • Heart disease, a heart attack, heart failure, or heart rhythm problems
  • High or low blood pressure
  • High cholesterol
  • A stroke
  • Kidney or liver disease
  • Diabetes
  • A blood disorder, such as multiple myeloma, leukemia, or sickle cell anemia

Viagra can lower blood flow to the optic nerve in your eye, which may cause sudden vision loss. Most people who experience this complication also have heart disease, high blood pressure, high cholesterol, diabetes, or specific eye problems. Being a smoker and over 50 years of age also increases the risk of vision issues.
