Is Viagra Generic

Is Viagra Generic

Manufacturer

The makers of Viagra, unless they decide to sell the brand or are acquired by a rival firm, will always be.

Sildenafil on the other hand, is open to wider reproduction, and can be made any pharmaceutical company; provided that they adhere to the same preparation and manufacturing conditions observed to make the original.

It should be noted that have also entered the generic market for Sildenafil, and produce their own version.

Efficacy, Side Effects and Contraindications

The results of the products are clinically the same.

As previously mentioned, Viagra and Sildenafil have the same active ingredient, and perform the same function in the body. This means that they have the same rate of efficacy, carry the same risks of side effects, and are subject to the same contraindicatory restrictions.

Despite the fact that Sildenafil is available, there is a reason that Viagra continues to sell so well; because it is the most established and recognisable prescription medication available for impotence, and will perhaps remain to be for some time.

Side Effects

While VIAGRA helps most patients with correcting their erectile dysfunction issues, there is the possibility of unwanted side effects when taking it. All medicines have a possibility of side effects and Viagra in Canada is no exception. Most are minor and temporary, however, but some may be serious and require medical attention. Speak to your doctor or other trusted healthcare professional immediately if you do not feel well on Viagra.

Common and less common side effects are:

  • Flushing
  • Headache
  • Nasal congestion
  • Stomach discomfort after meals
  • Abnormal vision (blurred vision, seeing shades of colors differently than before, or sensitivity to light)
  • Bladder pain
  • Cloudy or bloody urine
  • Dizziness
  • Increased urination or pain during urination
  • Diarrhea
  • Bleeding of the eye
  • Convulsions (seizures)
  • Decreased or double vision, or in extreme cases, blindness
  • A blue tint to your vision
  • Prolonged, painful, or inappropriate erection of penis (priapism)
  • Redness, burning, or swelling of the eye
  • Anxiety

Interactions

Care should be exercised by people who are also taking protease inhibitors for the treatment of HIV infection. Protease inhibitors inhibit the metabolism of sildenafil, effectively multiplying the plasma levels of sildenafil, increasing the incidence and severity of side effects. Those using protease inhibitors are recommended to limit their use of sildenafil to no more than one 25 mg dose every 48 hours. Other drugs that interfere with the metabolism of sildenafil include erythromycin and cimetidine, both of which can also lead to prolonged plasma half-life levels.

The use of sildenafil and an α1 blocker (typically prescribed for hypertension or for urologic conditions, such as benign prostatic hypertrophy) at the same time may lead to low blood pressure, but this effect does not occur if they are taken at least 4 hours apart.

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.
