What is Viagra?
Viagra was the first oral pill designed for men with erectile dysfunction (ED), a problem that faces millions of men in the United States and around the world Viagra relaxes muscles within the penis. This allows increased blood flow into the penis, necessary to achieve and maintain an erection.
How does Viagra work?
Viagra belongs to a class of medications known as Phosphodiesterase Type 5 Inhibitors, much like alternative ED treatments Cialis and Levitra, which improve blood flow to the penis, enabling men with erectile dysfunction to respond to sexual stimulation with an erection when they use Viagra. For an erection to occur, with or without the use of Viagra, several chemical messengers are released from the nervous system, one of these chemicals is Cyclic GMP. Its action is to relax muscle tissue allowing for the widening of blood vessels which flow into the penis. This causes blood to enter and fill the corpora cavernosa and corpora spongiosum, which causes an erection. After sexual intercourse has occurred and adequate stimulation has been removed, the body releases the enzyme phosphodiesterase (PDE5) which breaks down Cyclic GMP, resulting in the erection being lost. Sildenafil, the active ingredient of Viagra, works by inhibiting the effect of this enzyme, allowing the blood vessels to be dilated for longer which improves blood flow to the penis, helping to maintain and prolong an erection.
How do I use Viagra?
When you buy Viagra take it only as directed by your doctor, usually once daily as needed. Viagra is taken by mouth, approximately 1 hour before sexual activity and works best for most men. Take Viagra only before sexual activity.
What are the potential side effects from Viagra?
Before you buy Viagra check with your doctor if it is safe for you to continue taking Viagra. Frequent side effects from Viagra may include: Diarrhea, flushing, stomach upset, nasal stuffiness, headache and dizziness might occur. If these effects persist or worsen, consult your doctor immediately. If you experience a painful or prolonged erection that lasts more than 4 hours, stop using this medication and seek immediate medical attention.
What should I discuss with my doctor before taking Viagra?
Before you buy Viagra tell your doctor your medical history. If you have any of the following conditions, consult your doctor before taking this medication: If you have heart problems severe enough that sexual activity puts you in danger. If you have suffered from a heart attack, stroke, or life-threatening heart irregularities within the past 6 months.
What is the recommended dose for Viagra?
The standard doses range from 25 milligrams to 100 milligrams, depending on the medicine's effect. The usual dose is 50 milligrams. If you are over 65, have liver or kidney problems, or are taking erythromycin, ketoconazole, itraconazole, ritonavir, or saquinavir, a dose of 25 milligrams may be sufficient. Your doctor will adjust the dosage if the medicine is not working properly for you.
What should I do in case of overdose with Viagra?
If overdose with Viagra is suspected, contact your local poison control center or emergency room immediately. Symptoms of overdose may include severe dizziness, fainting, or prolonged erection.
