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 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, so practicing safe sex is still essential.

How does Viagra work?

Viagra works by relaxing the muscles in the walls of blood vessels, which results in increased blood flow to specific areas of the body including the penis. When combined with sexual stimulation, this results in the ability to achieve and maintain an erection, enhancing one's sexual experience.

How long does Viagra last?

Viagra works best within 30 to 60 minutes of ingestion but may be taken up to four hours before engaging in sexual activity. For optimal effectiveness, it is most advisable to take it one hour before planned sexual activity. Remember, you should not take more than one tablet of sildenafil within a 24-hour period to avoid potential complications.

How much does Viagra cost?

The price of your medication is contingent upon the strength and quantity you buy, making it essential to evaluate your options carefully. Many Americans question why is Viagra so expensive, yet by purchasing Viagra online, you could save up to 90% on the cost of your medication. You can achieve even better savings by opting for generic Viagra, which is called sildenafil, and by purchasing a 90-day supply of your medication. Plus, you do not need a Viagra coupon to access our attractive prices.

It is crucial to read the patient information and instructions thoroughly before using this medication to ensure safety and efficacy.

  • Take Viagra tablets orally according to your healthcare provider's instructions.
  • Sildenafil citrate generally works best within 30 to 60 minutes of administration but may be taken up to four hours prior to sexual activity.
  • Consuming a high-fat meal may delay the onset of Viagra's effects, so timing your doses before meals can be helpful.
  • Your Viagra dosage will depend on various factors, including your medical condition, concurrent medications, and your response to treatment.
  • You should not exceed one tablet of Viagra per day to prevent adverse effects.

Be sure to communicate with your doctor and pharmacist about the following:

  • If you have any known drug allergies.
  • The prescription and non-prescription medications you currently take.
  • Your complete medical history, particularly any heart problems, liver or kidney issues, high or low blood pressure, or blood disorders such as leukemia or sickle cell anemia.
  • Any physical deformities of the penis, such as Peyronie’s disease.
  • If you have previously been advised against sexual activity for health reasons.
  • If you are taking any nitrate medications for heart issues. This includes recreational drugs like poppers or amyl nitrate alongside nitroglycerin and its variants.
  • If you use marijuana.

Additionally, please be aware of the following:

  • This medication should not be administered to anyone under the age of 18 without appropriate medical guidance.
  • Viagra may cause dizziness or visual disturbances. It's best to refrain from driving, operating machinery, or engaging in activities requiring clear vision until you know how the drug affects you.
  • Combining Viagra with alcohol or marijuana may heighten dizziness or other side effects. Therefore, moderation is advisable during treatment. Notify your healthcare provider if you are using marijuana.
  • In women, the use of sildenafil should be limited to cases where it is explicitly indicated during pregnancy or breastfeeding, as it may adversely affect both the woman and the unborn child.

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

  • Flushing, which may present as warmth, redness, or a tingling sensation.
  • Headaches, dizziness, muscle or back pain, or gastrointestinal discomfort.
  • Changes in vision, including blurred vision or shifts in color perception.
  • Runny or congested nasal passages and nosebleeds.
  • Sleep disturbances such as insomnia.

Should you experience any of the following severe side effects, contact your doctor immediately:

  • Symptoms indicative of a heart attack, such as nausea, excessive sweating, chest pain or pressure, or pain radiating to the jaw or shoulder.
  • Any changes in vision or sudden loss of vision.
  • Prolonged or painful erections lasting over 4 hours.
  • Ringing in your ears or sudden hearing loss.
  • Irregular heartbeats.
  • Signs of an allergic reaction including rash, itching, dizziness, breathing difficulties, or swelling of the face, tongue, or throat.
