What is Viagra?

Viagra also known as sildenafil is used to treat erectile dysfunction and impotence in males. Viagra increases the blood flow around the body and to the penis helping to get and maintain an erection. Known as erection pills, sildenafil doesn't increase sexual desire and therefore 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 relaxes the muscles in the walls of blood vessels which causes an increased blood flow to particular areas of the body including increasing the blood flow to the penis. When sexually stimulated, this helps a man to get erect and then keep the erection. Viagra is most effective within 30 to 60 minutes of taking it although it can be taken up to four hours before sexual activity.

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

• Viagra is taken orally.
• Sildenafil citrate works best 30 to 60 minutes before sexual activity but may be taken up to four hours before sexual activity.
• Eating a high-fat meal could 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 Viagra more than once a day.

Make sure to tell your doctor and pharmacist:

• If you have any drug allergies.
• If you take any other prescription or non-prescription medications.
• Your medical history, especially if you have ever had heart problems including heart disease, heart attacks, strokes, congestive heart failure, heart rhythm problems or coronary artery disease, high or low blood pressure, or blood disorders such as leukemia, multiple myeloma, hemophilia or sickle cell anemia, liver disease, kidney disease, stomach ulcers or retinitis pigmentosa.
• Any penis deformities, such as Peyronie’s disease.
• If you have been told not to 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:

• Sildenafil should not be given to anyone under the age of 18 without medical advice.
• Viagra can make you dizzy or cause you vision problems. Do not drive, operate machines or do any other activities that require alertness or clear vision until you are sure you can do it safely.
• Viagra and alcohol or marijuana can increase the chance of dizziness or other side effects. Limit your alcohol intake while taking Viagra and ask your doctor what a safe amount of alcohol to take would be. 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.
