Side Effects of Viagra: Important Things You Should Know

Side Effects of Viagra: Important Things You Should Know

Viagra is a brand name for the prescription drug sildenafil, which is used to treat erectile dysfunction. Revatio, another form of sildenafil, is used to treat pulmonary arterial hypertension (PAH), a condition in which high blood pressure in blood vessels of the lungs and heart results in shortness of breath, dizziness, and tiredness. Viagra, popularly called “the little blue pill,” is an easy fix for those suffering from erectile dysfunction. But it must be taken only under certain conditions as it carries risks. The side effects of Viagra range from mild to serious. Learn more about it here.

What is Erectile Dysfunction?

This condition, which may be short-term or long-term, renders one unable to maintain an erection. In some cases, one can get an erection but not maintain it long enough for satisfactory sex. In other cases, one can get an erection but not each time sex is desired. Although erectile dysfunction is a common problem, it is not a normal one.

People are more likely to suffer from erectile dysfunction if they are:

  • Older
  • Have medical conditions or illnesses
  • Taking specific medications
  • Struggling with psychological or emotional issues
  • Overweight
  • Smokers
  • Have unhealthy lifestyle habits

Left untreated, erectile dysfunction can progress into deeper issues such as an unfulfilled sexual life, depression, inability to impregnate one’s partner and loss of intimacy, and ultimately, strained relationships.

How Does the Blue Pill Work?

Viagra’s active component, sildenafil, is a member of a group of drugs called phosphodiesterase 5 (PDE5) inhibitors. Phosphodiesterase is a type of enzyme, which can be found in skeletal muscle, vascular or visceral smooth muscle, brain, kidneys, platelets, lungs, and penile tissue.

PDE5 controls blood flow in the pulmonary arteries. Because the cells in the blood vessels of the lungs are the same as those in the penis, inhibitors allow blood vessels to relax, thus increasing blood flow to lungs and lowering pressure.

What Are the Side Effects of Viagra?

Risks of sildenafil include headaches, lightheadedness due to lowered blood pressure. In fact, among the side effects of Viagra include blood pressure falling down to dangerous levels. This occurs when it is taken with certain medicines, particularly nitrates. Nitrates are normally used to treat angina or chest pain.

Other possible, more severe side effects include priapism, in which an erection does not go away. It is advised to seek medical attention when the erection lasts over four hours. Left untreated, it can irreversibly damage the male sex organ.

Another side effect is the sudden loss of vision, which may signal an eye condition called non-arteritic anterior ischemic optic neuropathy. NAION is characterized by damage to the optic nerve caused by poor circulation of blood to the eye.

Other side effects of Viagra are sudden loss of hearing, decreased hearing or tinnitus, a ringing in the ear.

People taking Viagra could also experience stomach aches, stuffy or runny nose, back and muscle pain, nausea, rashes, and changes in color vision.

Key Takeaways

Viagra is a form of sildenafil that is prescribed for the treatment of erectile dysfunction. Erectile dysfunction, in which an erection cannot be maintained long enough for pleasurable intercourse, occurs mostly in older men or persons with medical conditions or psychological or emotional problems.

Side effects of Viagra include headaches, dizziness, lightheadedness, nausea, stomach pain, vision and hearing loss, among others. If you experience any of the following related to use, consult your doctor.
