Sildenafil Citrate

Chemical Name SILDENAFIL 

VIAGRA is a prescription medication designed to help men maintain an erection following sexual stimulation and be able to continue to enjoy lovemaking with their partner. It works by increasing blood flow to the penis to promote greater rigidity to an existing erection and the ability to maintain that level of rigidity.

The word existing is highlighted there as it is important to note as taking Viagra will not give you an erection - it will only enhance an existing one. Approved by Health Canada for over-the-counter prescription access, it is easy to order generic Viagra online with a prescription from a physician.

Generic Viagra Vs Branded Viagra

Generic Viagra is a viable alternative to branded Viagra for men who are trying to overcome erectile dysfunction. It is reported to have nearly the same level of efficacy as the branded tablets, and the appeal of generic Viagra is that of course it is priced lower and can be acquired with the same prescription for Viagra that you receive from your physician.

The same guidelines for use and safe practices apply to generic Viagra in the same sildenafil citrate way they do for the branded medication, and you can be assured that the availability of generic Viagra means it has also been approved by Health Canada. The vast majority (upwards of 80%) of men who order Viagra online or have their prescription filled in their local pharmacy receive the intended benefit of the medication, and this is also true for those choosing a more affordable alternative in generic Viagra.

Take VIAGRA exactly as prescribed by your healthcare professional. The correct dose for each patient will depend on their condition and response. It is recommended to take your daily dose of VIAGRA approximately one hour before you and your partner intend to have sex. Swallow the tablet whole with a glass of water, and before you buy Viagra be aware that taking more than one dose daily is inadvisable as it greatly increases the risk of severely low blood pressure.

Similarly, be aware when your order Viagra online that the time it takes to see the effects of VIAGRA varies from person to person. It normally takes between 30 minutes to 1 hour, and this tends to be true for generic Viagra as well. Patients may notice the medication takes longer to work after a heavy meal. VIAGRA takes effect more quickly when taken on an empty stomach. 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.


VIAGRA may not be right for some men, and most often because certain medical conditions prevent the individual from be able to take this medication. Patients should discuss the following medical conditions with their healthcare professional before taking branded or generic Viagra.

Be aware before your buy Viagra that it may be necessary to discuss any of the following medical conditions:

  • If you are taking any nitrate medication
  • Irregular heartbeat
  • Coronary artery disease
  • Heart attack, stroke or a history of heart conditions
  • High blood pressure / low blood pressure
  • Penile abnormalities, including curved penis and or birth defects
  • Bleeding problems
  • Retinitis pigmentosa
  • Conditions causing thickened blood or slower blood flow, including leukemia, multiple myeloma (tumors of the bone marrow, or polycythemia), sickle cell disease, and thrombocythemia (blood problems)
  • Priapism
  • Heart or blood diseases
  • Severe kidney problems or liver problems
  • Caution – under no circumstances should men increase their dose without consulting with their healthcare professional.
  • 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.
