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. It’s important to understand that Sildenafil does not increase sexual desire, and it will not cause an erection without sexual stimulation. Moreover, this medication does not prevent sexually transmitted diseases, thus it is essential to practice safe sex while using it.

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 the penis. When combined with sexual stimulation, this mechanism aids a man in achieving and maintaining an erection. Without such stimulation, Viagra may not produce the desired effect.

How long does Viagra last?

Viagra works best within 30 to 60 minutes of taking it, but it may be taken up to four hours before sexual activity. For optimal results, it is best to take it one hour prior to sexual engagement. It is crucial that you do not exceed one tablet of sildenafil within a 24-hour period to avoid any adverse effects.

How much does Viagra cost?

The price of your medication can vary depending on the strength and quantity you choose to purchase. Many Americans often question the high price of Viagra, but buying it online can help save you as much as 90% on costs. Furthermore, purchasing generic Viagra, known as Sildenafil, can result in even greater savings. When buying a 90-day supply, you can maximize your cost efficiency without needing any coupon for discounts.

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 it, but it 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.

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 advised against engaging in sexual intercourse for health reasons.
  • If you are currently 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 cause dizziness or vision problems. You should not drive, operate machinery, or engage in other activities requiring alertness or clear vision until you feel certain you can do so safely.
  • Combining Viagra with alcohol or marijuana may increase the risk of dizziness or other side effects. Thus, it is advisable to limit alcohol intake while taking Viagra. Inform your doctor if you are also using marijuana.
  • In women, sildenafil should only be used when clearly needed, especially during pregnancy or breastfeeding, as high blood pressure in the lungs can pose risks to both the pregnant woman and the unborn baby.

Common side effects of Viagra may include but are not limited to:

  • Flushing, which can include warmth, redness, or a tingling feeling.
  • Headaches, dizziness, and muscle or back pain along with an upset stomach.
  • Blurred vision or changes to your color vision.
  • Runny or stuffy noses and nosebleeds.
  • Sleep problems such as insomnia.

Contact your doctor if you experience any of the following Viagra side effects:

  • Signs of a heart attack, including nausea, sweating, chest pain or pressure, or pain spreading to your jaw or shoulder.
  • Any vision changes or sudden loss of vision.
  • A painful erection or one that lasts longer than 4 hours.
  • Ringing in your ears or sudden hearing loss.
  • Irregular heartbeat.
  • Symptoms of an allergic reaction such as rashes, itching, dizziness, difficulty breathing, or swelling of the face, tongue, or throat.
