Viagra: Frequently Asked Questions Answered

What is Viagra?

Viagra contains the prescription medication sildenafil, which is used to treat erectile dysfunction in men. It belongs to the phosphodiesterase type 5 (PDE5) inhibitor class of medicines. This medication increases blood flow to the penis by relaxing the muscles in the blood vessels. It helps men by achieving and maintaining an erection, but it has no effect on sexual desire or protects against sexually transmitted illnesses.

What are the uses of Viagra?

Viagra treats a sexual dysfunction called erectile dysfunction or impotence in men. While it does not arouse sexual desire, it does help achieve and maintain an erection. Available in three strengths of 25 mg, 50 mg, and 100 mg each, the dosage a doctor recommends depends on your health, medical conditions, and response to treatment. Take it 30 minutes to 60 minutes before sexual activity. Consume only one pill a day.

    Frequently Asked Questions about Viagra

    Viagra works by relaxing your muscles in the blood vessels, allowing blood to enter your penis. It helps you get an erection and maintain it for a long time. The effect of this medicine kicks in after 30 minutes or so. Remember to take viagra only as per your prescription.

    Viagra is available in three strengths: 25 mg, 50 mg, and 100 mg. A doctor will prescribe it to you depending on your health, the severity of your condition, and other medical conditions you may have. Consume it with a light meal at least 30 minutes before sexual activity.

    Though Viagra is a safe medicine, it may trigger adverse effects in those with pre-existing heart problems. Some people with an existing heart condition have reported a heart attack, stroke, or irregular heart rate after taking Viagra. However, clinical studies have failed to prove a correlation between Viagra and heart problems.

    Patients should not take Viagra if they:
    • Are below 18 years of age
    • Are allergic to the drug sildenafil
    • Take medicines for pulmonary arterial hypertension (high blood pressure in the arteries of the lungs)
    • Use a class of medicines called nitrates for chest pain
    • Have heart or liver problems
    • Have low blood pressure
    • Have recently had a stroke, or other heart problems
    • Have retinitis pigmentosa (an inherited eye condition)
    • Have Peyronie's disease (curved, painful erections due to the presence of fibrous scar tissue)
    • Have stomach ulcers
    • Have hemophilia (an inherited bleeding disorder)
    • Have leukemia (cancer of the white blood cells), multiple myeloma (cancer of the bone marrow), or sickle cell anemia (a red blood cell abnormality).

    The effects of Viagra last one to four hours, depending on factors such as your age, medical condition, and prescribed dose. Studies have shown that if you sleep after taking Viagra, you may experience a significant increase in nighttime erections. Do not take Viagra without a doctor’s prescription.

    Viagra dilates the blood vessels and causes increased blood flow to the genitals in women. It may lead to increased sensitivity and arousal in women. However, it may also result in side effects such as headaches, nasal congestion, flushing, nausea, hot flashes, visual disturbances, etc. Since Viagra is a prescription medicine for men with erectile dysfunction, women should not take it.

    The best time to take Viagra is 30 to 60 minutes before sexual activity. Doctors recommend a dose of between 25 mg, 50 mg, and 100 mg based on your age, the severity of your condition, and other medical ailments.

    Viagra is a prescription medicine, meaning it is not available over the counter. Erectile dysfunction or impotence is a medical condition needing doctor's supervision, so seek the opinion of a healthcare professional to determine the reason behind this condition and take steps to handle it.

    Do not take Viagra more than once every 24 hours. Taking it too often could result in undesired side effects such as a severe drop in blood pressure, difficulty breathing, hearing, and visual problems, dizziness, etc.

    Viagra pills are safe if they are taken as per a doctor's prescription. Changes in dose or duration should not be made at any time because they may cause serious side effects. This medication may not be safe for individuals with high blood pressure, those who have recently had a heart attack, or those who are taking alpha-blockers (a type of medicine used to treat high blood pressure).
