What is Viagra?

Viagra is the brand name of the sildenafil medication, primarily used to treat erectile dysfunction and impotence in men. It works by increasing blood flow to the penis, which helps a man achieve and sustain an erection. It's important to note that sildenafil does not enhance sexual desire and will not induce an erection without sexual stimulation. Additionally, this medication does not protect against sexually transmitted infections, so it is essential to practice safe sex.

How does Viagra work?

Viagra functions by relaxing the muscles within the walls of blood vessels, promoting increased blood flow to specific areas of the body, including the penis. When taken in conjunction with sexual stimulation, this mechanism aids in achieving and maintaining an erection.

How long does Viagra last?

Viagra is most effective when taken within 30 to 60 minutes before sexual activity, although it may be taken up to four hours beforehand. For optimal results, it is often taken about one hour prior to sexual intercourse. Do not exceed more than one tablet of sildenafil within a 24-hour period.

How much does Viagra cost?

The price of Viagra depends on its strength and quantity. Many Americans wonder why Viagra is so expensive; however, purchasing Viagra online can save you up to 90% of the retail cost. Moreover, opting for the generic version, sildenafil, and buying a 90-day supply can lead to even greater savings. No Viagra coupon is necessary to access our competitive pricing.

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

  • Take Viagra tablets by mouth as directed by your healthcare provider.
  • Sildenafil citrate is most effective when taken 30 to 60 minutes prior to sexual activity but may be consumed up to four hours in advance.
  • Consumption of a high-fat meal can delay the onset of Viagra’s effects.
  • Your Viagra dosage is determined by various factors, including your medical health, any other medications you may be taking, and your response to treatment.
  • Do not exceed one tablet of Viagra within any 24-hour period.

Ensure to inform your doctor and pharmacist:

  • If you have any known drug allergies.
  • About the other prescription and non-prescription medications you currently take.
  • Your medical history, especially regarding heart conditions such as heart disease, heart attacks, strokes, congestive heart failure, heart rhythm disorders, or coronary artery disease. Also include any history of liver or kidney disease, high or low blood pressure, or blood disorders like leukemia, multiple myeloma, hemophilia, or sickle cell anemia, as well as stomach ulcers or retinitis pigmentosa.
  • If you have any physical deformity of the penis, such as Peyronie’s disease.
  • If you have been advised against engaging in sexual intercourse for health reasons.
  • If you are utilizing any nitrate drugs for chest pain or heart problems. These include recreational drugs like poppers or amyl nitrate, as well as nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate.
  • If you are using marijuana.

Additionally, be mindful that:

  • This medication should not be administered to anyone under the age of 18 without medical guidance.
  • Viagra may lead to dizziness or vision problems. Avoid driving, operating machinery, or engaging in activities that necessitate alertness and clear vision until you feel safe doing so.
  • The combination of Viagra with alcohol or marijuana may heighten dizziness or other side effects. Caution is advised in limiting alcohol intake while using Viagra. Inform your healthcare provider if you are also using marijuana.
  • In women, sildenafil should only be utilized when clearly warranted during pregnancy or breastfeeding since high blood pressure in the lungs can be detrimental to the mother and unborn child.

Common side effects associated with Viagra may include, but are not limited to:

  • Flushing, which encompasses sensations of warmth, redness, or a tingling feeling.
  • Headaches, dizziness, muscle or back pain, or gastrointestinal discomfort.
  • Blurred vision or alterations to color vision.
  • Nasal congestion or bleeding.
  • Sleep disturbances, including insomnia.

Contact your doctor if you experience any serious side effects from Viagra, such as:

  • Heart attack symptoms like nausea, cold sweats, chest pain or pressure, or discomfort radiating to the jaw or shoulder.
  • Changes in vision or sudden loss of vision.
  • An erection that is painful or lasts more than 4 hours.
  • Ringing in the ears or sudden hearing loss.
  • Irregular heartbeat.
  • Signs of an allergic reaction, such as rashes, itching, lightheadedness, difficulty breathing, or swelling of the face, tongue, or throat.

Q: What is the generic alternative to Viagra?

A: The generic form of Viagra is known as sildenafil and may result in even greater cost savings for you. You can purchase 25mg, 50mg, and 100mg options of both Viagra and sildenafil.

Q: What are the available strengths of Viagra?

A: Viagra is available in strengths of 25mg, 50mg, and 100mg, with sildenafil as a generic alternative.
