What is the difference between Viagra and Sildenafil?

Chemically, Viagra and Sildenafil are the same drug. They both have the same ingredients list (sildenafil). The only difference is that Viagra has a brand name on it, which makes it more expensive, whereas Sildenafil is what is known as a “generic” drug. There is no difference in side effects, dosage, or interference with other medications between the two products.

However, if you have previously been taking Viagra, and are taking multiple medications that mean you may get them confused if you changed the name/packet type of your painkiller, you may wish to continue taking Viagra.

How does Viagra work?

Viagra contain the active ingredient sildenafil, which belongs to a group of medicines called PDE5 inhibitors. The treatment works by relaxing blood vessels in the penis, allowing blood to flow more freely. Bear in mind that Viagra only works in conjunction with sexual stimulation, and the medication alone will not give you an erection.

Is Viagra suitable for me?

Although Viagra is designed for men suffering from erectile dysfunction, your medical history and other medications may mean it isn’t right for you.

Speak to your doctor before using Viagra if:

  • You are allergic to sildenafil or any of the other ingredients listed in the patient information handbook
  • You are taking nitrates or nitric oxide donors/poppers
  • You are taking riociguat for high blood pressure in the lungs
  • You have severe heart or liver problems
  • You have had a stroke or heart attack
  • You have low or uncontrolled high blood pressure
  • You have a deformity of your penis or Peyronie’s Disease

What are the side effects of using Viagra?

Like all medications, Viagra may have side effects, but not everyone gets them. Common side effects include:

  • Headaches
  • Facial flushing
  • Indigestion
  • Stuffy nose
  • Nausea

If you think you may be having an allergic reaction (swelling of the hands and face, difficulty breathing) contact a doctor immediately.

You should always follow your doctor’s recommendation on taking Viagra, and only use the following information as a guide. Although the tablets can be taken with of without food, the effect may be delayed if taken with a heavy meal or reduced if taken with alcohol.

The recommended starting dose for Viagra is 50mg one hour before sexual activity. Do not take more than one dose in 24 hours, and do not take more than 100mg in one dose as it will not increase the effect.

Dosage instructions
Take ONE tablet approximately 1 hour before sexual activity. Adjust according to response up to a maximum of 100mg per day. Maximum ONE dose per day.
