Buy Brand and Generic Viagra Online

It is quick, easy and affordable to buy Viagra and the generic alternative Sildenafil online with Canada Drug Warehouse. We are the perfect solution to high drug prices in the USA.

What is Viagra?

Viagra is the brand name of sildenafil medication and is used to treat erectile dysfunction and impotence in men. Viagra increases the blood flow to the penis helping a man to get and keep an erection. Sildenafil does not increase sexual desire and will not cause an erection without sexual stimulation. This medication does not prevent sexually transmitted disease and you should still practice safe sex.

How does Viagra work?

Viagra works by relaxing the muscles in the walls of blood vessels which results in increased blood flow to particular areas of the body including increasing the blood flow to the penis. When combined with sexual stimulation, this results in helping a man to get and keep an erection.

How long does Viagra last?

Viagra works best within 30 to 60 minutes of taking but may be taken up to four hours before sexual activity. It is most effective when taken one hour before sexual activity. You should not take more than one tablet of sildenafil within a 24 hour period.

How much does Viagra cost?

The price of your medication depends on the strength and quantity you buy. Lots of Americans question why is Viagra so expensive but through buying Viagra online could save up to 90% on the cost of your medication. You can make even better savings through buying generic Viagra called sildenafil and by buying a 90 day supply of your medication. You do not need a Viagra coupon in order to get our great prices.

Always read the patient information and instructions carefully before using this medication.

  • Take Viagra tablets by mouth.
  • Sildenafil citrate works best within 30 to 60 minutes of taking but may be taken up to four hours before sexual activity.
  • Eating a high-fat meal may delay the time it takes for Viagra to work.
  • Your Viagra dosage is based on a number of factors including your medical condition, other medications you may take and your response to treatment.
  • You should not take more than one tablet of Viagra per day.

Cautions

Make sure to tell your doctor and pharmacist:

  • If you have any drug allergies.
  • Which other prescription and non-prescription medications you currently take.
  • Your medical history, especially of heart problems such as heart disease, heart attacks, strokes, congestive heart failure, heart rhythm problems or coronary artery disease. Any liver disease, kidney disease, high or low blood pressure, or blood disorders such as leukemia, multiple myeloma, hemophilia or sickle cell anemia, stomach ulcers or retinitis pigmentosa.
  • If you have any physical deformity of the penis, such as Peyronie’s disease.
  • If you have ever been told you shouldn’t have sexual intercourse for health reasons.
  • If you are taking any nitrate drugs for chest pain or heart problems. Nitrate drugs include recreational drugs such as poppers or amyl nitrate as well as nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate.
  • If you are using marijuana.

Also be aware that:

  • This medication should not be given to anyone under the age of 18 without medical advice.
  • Viagra may make you dizzy or cause you vision problems. You should not drive, operate machinery or do any other activities requiring alertness or clear vision until you can do it safely.
  • Viagra and alcohol or marijuana may increase dizziness or other side effects. You should limit your alcohol intake while taking Viagra. Tell your doctor if you are also using marijuana.
  • In women, sildenafil should only be used when clearly needed when pregnant or breast feeding, as high blood pressure in the lungs may harm both the pregnant woman and the unborn baby.
