What is Viagra?

Viagra is the brand name of the medication sildenafil, prescribed for treating erectile dysfunction and impotence among men. This medication is effective as it increases blood flow to the penis, helping a man to achieve and maintain an erection. It is important to note that sildenafil does not increase sexual desire on its own and will not induce an erection without sexual stimulation. Furthermore, this medication does not offer protection against sexually transmitted diseases; therefore, practicing safe sex is crucial.

How does Viagra work?

Viagra operates by relaxing the smooth muscles found in the walls of blood vessels, which leads to heightened blood flow in specific areas of the body, notably the penis. When taken in conjunction with sexual stimulation, this increase in blood flow can assist men in both achieving and sustaining an erection.

How long does Viagra last?

Viagra typically becomes most effective within 30 to 60 minutes after ingestion but may be taken up to four hours prior to engaging in sexual activity. For optimal results, it is advised to consume Viagra about one hour before planned sexual activity. It is important to refrain from taking more than one tablet of sildenafil in a 24-hour period to avoid potential side effects.

How much does Viagra cost?

The cost of your medication may vary based on the strength and quantity selected. Many individuals question the high price of Viagra; however, purchasing Viagra online can result in savings of up to 90% compared to traditional pharmacy prices. Further savings can be achieved by opting for generic Viagra, known as sildenafil, especially when ordering larger quantities such as a 90-day supply. No Viagra coupon is necessary to access our competitive prices.

Always read the patient information and instructions thoroughly before utilizing this medication.

  • Take Viagra tablets by mouth, as prescribed.
  • Sildenafil citrate is most effective within 30 to 60 minutes of taking it but can be consumed up to four hours before sexual activity.
  • Consuming a high-fat meal may delay the onset of Viagra's effectiveness.
  • Your Viagra dosage depends on various factors, such as your medical condition, other medications you may be taking, and your response to the treatment.
  • Do not exceed one tablet of Viagra per day to avoid complications.

Ensure you inform your doctor and pharmacist about the following:

  • If you have any known drug allergies.
  • Any other prescription or non-prescription medications you are currently taking.
  • Your complete medical history, particularly regarding heart issues such as heart disease, heart attacks, strokes, congestive heart failure, heart rhythm problems, or coronary artery disease, as well as any liver or kidney disorders, 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 structural deformity of the penis, including Peyronie’s disease.
  • If you have previously been advised against sexual intercourse for health reasons.
  • If you are taking any nitrate drugs for chest pain or heart-related issues, including recreational drugs such as poppers or amyl nitrate, along with nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate.
  • If you are using marijuana.

Please also be cognizant of the following:

  • This medication should not be administered to individuals under the age of 18 without appropriate medical advice.
  • Viagra may cause dizziness or vision problems; avoid driving, operating machinery, or performing any tasks that require clear vision until you are certain it is safe to do so.
  • Combining Viagra with alcohol or marijuana can heighten dizziness and other side effects; it is wise to limit alcohol intake while on this medication. Communicate with your doctor if you also consume marijuana.
  • In women, sildenafil should be utilized only when necessary during pregnancy or breastfeeding, as high blood pressure in the lungs can adversely affect both the pregnant individual and their unborn child.

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

  • Flushing, which might present as warmth, redness, or a tingling sensation.
  • Headaches, dizziness, back pain, muscle discomfort, or upset stomach.
  • Vision alterations, including blurred or color vision changes.
  • Runny or congested nasal passages and potential nosebleeds.
  • Sleeping issues such as insomnia.

If you experience any following severe side effects from Viagra, it's crucial to contact your doctor instantly:

  • Heart attack symptoms, including nausea, sweating, chest pain or pressure, or discomfort radiating to your jaw or shoulder.
  • Changes in vision or sudden vision loss.
  • A painful erection or one lasting more than four hours.
  • Ringing in the ears or sudden hearing loss.
  • Irregular heartbeat.
  • Signs of an allergic reaction, such as rashes, itching, dizziness, breathing issues, or swelling of the face, tongue, or throat.
