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. This medication is known for its reliability and effectiveness. However, it is critical to understand that sildenafil does not increase sexual desire and will not cause an erection without sexual stimulation. This medication does not prevent sexually transmitted diseases, and you should still practice safe sex at all times.

How does Viagra work?

Viagra works by relaxing the muscles in the walls of blood vessels, resulting in increased blood flow to particular areas of the body, including increasing the blood flow to the penis. When combined with sexual stimulation, this effectively aids in helping a man to get and maintain an erection, making it a popular choice among men experiencing ED.

How long does Viagra last?

Viagra works best within 30 to 60 minutes of taking the medication but may be taken up to four hours before sexual activity. It is most effective when taken one hour before sexual activity for optimal results. Caution must be exercised, as one should not take more than one tablet of sildenafil within a 24-hour period to avoid potential adverse effects.

How much does Viagra cost?

The price of your medication depends on the strength and quantity you buy, and many Americans often question why Viagra is so expensive. However, by purchasing Viagra online, you could save up to 90% on the cost of your medication! You can maximize your savings even further by opting for generic Viagra, known as sildenafil, and by purchasing a 90-day supply of your medication. Importantly, you do not need a Viagra coupon in order to benefit from our great prices.

Always read the patient information and instructions carefully before using this medication to ensure safe use.

  • Take Viagra tablets by mouth as directed by your physician.
  • Sildenafil citrate works best within 30 to 60 minutes of taking the medication, 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, potentially impacting its effectiveness.
  • Your Viagra dosage is based on multiple factors, including your medical condition, other medications you may take, and your response to treatment.
  • It is crucial not to take more than one tablet of Viagra per day to avoid serious side effects.

Make sure to inform your doctor and pharmacist of the following:

  • If you have any known drug allergies.
  • Which other prescription and non-prescription medications you are currently taking.
  • Your medical history, especially regarding heart problems such as heart disease, heart attacks, strokes, congestive heart failure, irregular heartbeats, or coronary artery disease. Disclose any liver disease, kidney disease, high or low blood pressure, or blood disorders such as leukemia, multiple myeloma, hemophilia, or sickle cell anemia, as well as any 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 sexual intercourse for health reasons.
  • If you are taking any nitrate drugs for chest pain or heart problems, which can include recreational drugs like poppers or amyl nitrate, along with nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate.
  • If you are using marijuana or other substances.

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. As such, you should not drive, operate machinery, or engage in any activities requiring alertness or clear vision until you can do so safely.
  • Additionally, be cautious when combining Viagra with alcohol or marijuana, as this may heighten dizziness or other side effects. Limit your alcohol intake while taking Viagra and inform your doctor if you are also using marijuana.
  • For women, sildenafil should only be utilized when clearly needed during pregnancy or breastfeeding, as it may pose risks of high blood pressure to both the pregnant woman and the unborn child.

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

  • Flushing, warmth, redness, or a tingling sensation.
  • Headaches, dizziness, muscle or back pain, or an upset stomach.
  • Blurred vision or changes to your color vision.
  • Runny or stuffy noses and nosebleeds.
  • Sleep disturbances such as insomnia.

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

  • Heart attack symptoms such as nausea, sweating, chest pain or pressure, or pain spreading to your jaw or shoulder.
  • Vision changes or sudden vision loss.
  • A painful erection or one that persists for over 4 hours.
  • Ringing in your ears or sudden hearing loss.
  • Irregular heartbeat or palpitations.
  • Symptoms of an allergic reaction such as rashes, itching, dizziness, problems breathing, or swelling of the face, tongue, or throat.
