What is Viagra?

Viagra is the brand name of the sildenafil medication and is used to treat erectile dysfunction and impotence in men. Viagra increases blood flow to the penis, helping a man to achieve and maintain an erection. It's important to note that sildenafil does not increase sexual desire and will not cause an erection without sexual stimulation. This medication does not prevent sexually transmitted diseases, thus practicing safe sex is essential.

How does Viagra work?

Viagra works by relaxing the muscles in the walls of blood vessels, resulting in increased blood flow to specific areas of the body, including facilitating blood flow to the penis. When taken in conjunction with sexual stimulation, this results in helping a man to achieve and sustain an erection.

How long does Viagra last?

Viagra typically works best within 30 to 60 minutes of ingestion but may be taken as early as four hours before sexual activity. It is most effectual when taken approximately one hour prior to engaging in sexual activity. It’s crucial that you do not exceed the recommended dosage of one tablet of sildenafil within a 24-hour time frame.

How much does Viagra cost?

The price of your medication varies based on the strength and quantity purchased. Many Americans question why Viagra is so expensive; however, buying Viagra online may save you up to 90% on your medication costs. Moreover, you can save even more by choosing the generic Viagra (sildenafil) and purchasing a larger supply, such as a 90-day amount. It's important to mention that you do not require a Viagra coupon to access our competitive prices.

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

  • Take Viagra tablets by mouth.
  • Sildenafil citrate is most effective when taken within 30 to 60 minutes prior to sexual activity but may be taken up to four hours in advance.
  • Consuming a high-fat meal may delay the onset of efficacy for Viagra.
  • Your Viagra dosage should be determined based on several factors, including your medical condition, other medications you may be taking, and your overall response to treatment.
  • Do not take more than one tablet of Viagra daily.

Make sure to inform your healthcare provider and pharmacist:

  • If you have any drug allergies.
  • What other prescription and non-prescription medications you are currently taking.
  • Your medical history, particularly concerning heart issues such as heart disease, heart attacks, strokes, congestive heart failure, heart rhythm disorders, or coronary artery disease. Any liver or kidney disease, blood pressure issues, or blood disorders like leukemia, multiple myeloma, hemophilia, or sickle cell anemia, and any prior stomach ulcers or retinitis pigmentosa.
  • If you have any physical deformities 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 medications for chest pain or other heart conditions. This includes recreational substances like poppers or amyl nitrate along with prescribed medications such as nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate.
  • If you are using marijuana.

Be aware that:

  • This medication should not be administered to anyone under the age of 18 without appropriate medical advice.
  • Viagra may cause dizziness or vision issues. Avoid driving, operating machinery, or engaging in activities requiring alertness or clear eyesight until you can confirm your safety.
  • Using Viagra alongside alcohol or marijuana may amplify dizziness or other side effects. It is advisable to limit alcohol consumption while taking Viagra. It’s important to inform your doctor if you are also utilizing marijuana.
  • For women, sildenafil should only be utilized when absolutely necessary during pregnancy or breastfeeding, as high blood pressure in the lungs may pose risks to both the mother and the unborn child.

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

  • Flushing, including sensations of warmth, redness, or a tingling sensation.
  • Headaches, dizziness, muscle or back pain, or gastrointestinal discomfort.
  • Blurred vision or alterations in color perception.
  • Runny or congested nasal passages, along with potential nosebleeds.
  • Sleep disturbances such as insomnia.

Please consult your healthcare provider if you experience any of the following serious side effects:

  • Heart attack symptoms, including nausea, sweating, chest discomfort or pressure, or pain radiating to your jaw or shoulder.
  • Changes in vision or sudden vision loss.
  • A painful or prolonged erection lasting more than 4 hours.
  • Tinnitus or sudden hearing loss.
  • Irregular heartbeats.
  • Signs of an allergic reaction, such as rashes, itching, dizziness, breathing difficulties, or swelling of the face, tongue, or throat.
