Facts about erectile dysfunction and sildenafil: Approximately 40% of men over 40 experience some signs of erectile dysfunction. The cause of erectile dysfunction can be from a variety of things both physical and mental. Common reasons for erectile dysfunction include heart disease, smoking, alcohol use, and depression. Oral medications such as sildenafil (generic viagra) have shown to be successful in helping men get and maintain an erection long enought to have sex.

How Does it Work?

Sildenafil was the first drug in the category called PDE-5 inhibitors that was approved for treatment of erectile dysfunction. PDE-5 is an enzyme that degrades nitric oxide levels in many locations throughout the body. In the case of erectile dysfunction, PDE-5 degrades nitric oxide levels in the penis, lessening the quality of erection or eliminating it altogether. Sildenafil binds to PDE-5 and blocks its nitric oxide degrading ability, allowing the dilation of blood vessels and facilitating an erection. Once taken, sildenafil is rapidly absorbed by the small intestine, and its erectogenic effects can be expected in as little as 30-120 minutes. Taking it on an empty stomach may significantly reduce the time it can take to be effective. Perhaps the most interesting aspect of sildenafil is that it will not cause an erection in the absence of sexual stimulation. This is due to the complex interaction between the nervous, endocrine, and vascular system that allows for an erection to occur. It simply facilitates the ability of a natural process to occur and does so with precision, not affecting other systems within the body. 

Effectiveness

Undoubtedly, it has been proven effective time and time again. Its ability to improve male sexual function has been tested by researchers and rated based on a variety of parameters including frequency of penetration, maintenance of erections after penetration, orgasmic function, intercourse satisfaction, sexual desire, and overall satisfaction. Based upon these criteria, sildenafil has been shown to be 80% effective for males under the age of 65, 69% effective for men between the ages of 65-74, and 59% effective for those 75 years of age and older. Sildenafil reviews by patients and practitioners alike report that it has stood the test of time and remains a reliable treatment for erectile dysfunction with minimal side effects. 

How to Use Sildenafil

Typical Usage

Sildenafil can be taken as needed to treat erectile dysfunction for sexual activity. It increases blood flow to the penis upon stimulization in order to get an erection.

Dosage

Common doses range from 25mg to 100mg. Talk to the Invigor Medical practitioner to see what dosage works best for you.

Precautions & Side Effects of Sildenafil

Sildenafil has developed a reputation of being incredibly safe and effective. That being said, there is the risk of some side effects when taking sildenafil for erectile dysfunction. The most commonly reported side effects include headaches which typically occur in 16% of men, and flushing, seen in 10% of men on average. Both of these common side effects are generally short-lived. There are many medications that may be unsafe to take with sildenafil including nitrates and those that have an effect on blood pressure. This is why it is important to speak with a medical professional before using this impressively effective treatment for erectile dysfunction.

Ask The Experts

Frequently Asked Questions
Why is this medication prescribed?
Sildenafil is in a class of medications called phosphodiesterase inhibitors. Medications in this class are used to treat erectile dysfunction and pulmonary artery hypertension. Phosphodiesterase inhibitors treat erectile dysfunction by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection.
What is the success rate for this medication?
The success rate for sildenafil in treating ED depends on the underlying condition that caused ED but can range from 50%-85%.
Is there anything I should know about what this medication cannot treat?
Sildenafil does not cure ED, affect the libido, prevent pregnancy, or protect against sexually transmitted diseases such as human immunodeficiency virus.
Are there any secondary uses for this medication?
Sildenafil is also used to treat pulmonary hypertension. It relaxes the smooth muscles in the walls of small blood vessels, which increases blood flow to the lungs.
How should this medication be used?
Sildenafil is taken as needed before sexual activity. It is best taken approximately 1 hour before sexual activity but can be taken any time from 4 hours to 30 minutes before sexual activity.
Do not take sildenafil more than once every 24 hours.
If you are using the oral liquid, shake the bottle well for at least 10 seconds before measuring the dose. Wash the oral syringe after each use.
What is the typical dosage range for this medication?
The usual initial dose for sildenafil is 50mg orally once a day, as needed, one hour before sexual activity.
Maintenance dose: 25-100 mg orally once a day as needed, one hour prior to sexual activity.
Usual geriatric dose for ED: 25 mg orally one hour prior to sexual activity
How long does it take for this medication to start working?
Sildenafil typically induces an erection within 30 minutes of taking the medication.
How long do the effects of this medication typically last?
Sildenafil continues to work for up to four hours. Most men will see a decline in medication effect after two hours.
Are there any special precautions for using this medication
As with all medications for ED, you should not use sildenafil if a health care provider has ever told you that your heart is not healthy enough for sexual activity. Before taking sildenafil, notify your health care provider if you:
• Are allergic to sildenafil or any components of sildenafil. Have a condition that predisposes you to priapism (a painful erection lasting over 4 hours)
• Are taking any other prescription or nonprescription drugs or supplements as they may adversely affect how sildenafil is broken down in the body, which can lead to potentially dangerous side effects or drug interactions.
• Are taking street drugs or herbs (such as St. John’s wort), which can cause dangerous side-effects.
• Are taking any medications to treat pulmonary arterial high blood pressure. These medications and sildenafil act in the same way and can cause an overdose.
• Have heart problems, high or low blood pressure, blood circulation problems, retinitis pigmentosa, blindness in one or both eyes, bleeding problems, a stomach ulcer, pulmonary venous-occlusive disease, liver or kidney disease, a blood cell disorder, or a physical disorder of the penis called Peyronie’s disease, or if a health care provider has ever advised you not to have sexual intercourse.
What should I do if I forget a dose?
No required dosing schedule is needed when using sildenafil for erectile dysfunction, except do not take more than one dose in 24 hours.
How should this medication be stored?
Store sildenafil in its original, closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing. Keep sildenafil in a safe location away from children.
