Why is this medication prescribed?

Pfizer saw an economic advantage with this new discovery and experienced immediate success with Viagra, accumulating about a billion dollars in sales in its first year alone. In 2014, Fox News reported that “over 30 million men suffer from erectile dysfunction,” and it is estimated that approximately 20 million Americans have taken Viagra. Men’s Health reported around the same time that during the last two or three decades, ED rates have gone up, especially among younger men. The Journal of Sexual Medicine published results from one study that showed that “one out of every four new ED patients is under 40 years old.” In 2016, the FDA approved the first-ever generic version of Viagra to be manufactured and distributed by Teva, a Pennsylvania-based pharmaceutical company. The drugs entered the market in December 2017.

Dosage Forms & Strengths

Experts have linked Viagra to some serious side effects affecting the eyes, ears, penis, heart and blood vessels. A 2014 study published in JAMA Internal Medicine also points to a possible link between the use of sildenafil (the active ingredient in Viagra) and melanoma, the most dangerous form of skin cancer. However, the significance of this link is still unclear. Viagra is an oral medication used to treat erectile dysfunction (ED) in men. An erection occurs when blood flow increases into the penis, making it expand and become firm.

Can Viagra be crushed, split, or chewed?

Two long chambers inside the penis, called the corpora cavernosa, contain spongy tissue that collects blood flowing into the chambers, creating pressure that results in the expansion of the penis. Viagra blocks certain naturally occurring enzymes in the body, causing blood vessels to relax and enhancing blood flow to the penis. Viagra does not automatically cause an erection; rather, it assists a man with ED in obtaining and keeping an erection when sexually aroused or stimulated. The active ingredient in Viagra can treat other disorders. Doctors prescribe Revatio (sildenafil) for adults with pulmonary arterial hypertension (PAH). When they expire or you don’t need them anymore, get rid of them. Commonly known as “the little blue pill,” Viagra has raked in billions for pharmaceutical giant Pfizer since its 1998 release. But the erectile dysfunction drug has links to serious side effects, including vision and hearing loss, heart complications and melanoma.

Can everyone use Viagra?

PAH is a progressive, life-threatening disorder that causes abnormally high blood pressure in the pulmonary artery, which is the blood vessel responsible for carrying blood from the heart to the lungs. Revatio works to improve a patient’s ability to exercise and slow down the progression and worsening of the disease. Signs and symptoms of this serious health condition can include shortness of breath when active, fainting spells, dizziness, swelling of the ankles or legs, chest pain and a rapid heart rate. The National Institutes of Health (NIH) defines erectile dysfunction as “a condition in which a man is unable to get or keep an erection firm enough for sexual intercourse.” Signs of erectile dysfunction (ED), sometimes referred to as impotence, may include the ability to get an erection sometimes but not every time, the ability to get an erection that does not last long enough to engage in sexual intercourse or the inability to get an erection at any time. Physical causes for the condition can include nerve damage, artery damage or damage to the smooth muscles and fibrous tissues in the penis.

Prevention & Wellness

Certain diseases and health complications can also lead to ED, such as high blood pressure and diabetes. Psychological and emotional disorders, such as anxiety, depression and stress, can cause or exacerbate ED. Certain lifestyle choices have an effect as well, such as an unhealthy diet, lack of exercise, drinking in excess and smoking. ED can also be a potential side effect when taking certain medications, including those used to treat blood pressure, allergies, depression and ulcers. Complications of the condition can result in an unfulfilled sex life, emotional problems — such as depression and anxiety — a loss of intimacy with a partner, a strained relationship and the inability to get a partner pregnant.
