Understanding Sildenafil
-
What is Sildenafil?
Sildenafil, which is the generic form of Viagra, is an oral medication that is available only by prescription and is widely recognized for its role in treating male sexual dysfunction. Also referred to as impotence or erectile dysfunction (ED), Sildenafil works by improving blood flow to the penis when taken before sexual activity, and it is recommended that it be used no more than once every 24 hours. Besides its application in ED, Sildenafil is also employed in the treatment of pulmonary arterial hypertension (PAH), a serious condition affecting blood pressure within the lungs, and is appropriate for both men and women. However, patients should recognize that these uses are separate, and the products should not be interchanged. It is crucial that individuals understand the specific purpose and correct usage of each form of Sildenafil to maximize treatment effectiveness.
-
How does Sildenafil work?
Sildenafil functions as a phosphodiesterase type 5 (PDE-5) inhibitor. When coupled with sexual arousal, it facilitates increased blood flow to the penis, assisting men in achieving and sustaining an erection. It is important to note that Sildenafil does not induce an erection on its own; sexual stimulation is a necessary component for its effectiveness. This targeted action on the PDE-5 enzyme is what makes Sildenafil a critical option for those suffering from erectile dysfunction.
-
How to take Sildenafil for best results
To achieve optimal results with Sildenafil, it is generally recommended that the medication be taken approximately one hour prior to engaging in sexual activity. However, it can be consumed anytime between 30 minutes to four hours ahead of time. It is important to follow the prescribed directions and refrain from taking more than one dose within a 24-hour period. Sildenafil can be ingested either with food, which may slightly delay its effects, or on an empty stomach for potentially faster action.
-
How long does Sildenafil take to work?
When correctly utilized and combined with sexual stimulation, Sildenafil typically begins to take effect within approximately 60 minutes. However, individual responses can vary, and factors such as overall health and the presence of food in the stomach may influence the precise timing of its effects.
-
How long does Sildenafil last?
The effects of Sildenafil can last anywhere from two to four hours, allowing for the possibility of engaging in sexual activity during this period. If an erection persists for more than four hours, medical attention should be sought immediately, as this may indicate a rare but serious condition known as priapism.
-
What are the side effects of Sildenafil?
As with any medication, Sildenafil may cause side effects, some of which could be noteworthy. Common side effects experienced by users include headache, facial flushing (a warm sensation often affecting the cheeks, neck, and chest), nasal congestion, and indigestion. Generally, these side effects are temporary and should subside after the medication's effects wear off. Patients are advised to consult their healthcare provider if these side effects persist. In certain rare instances, serious side effects may occur, such as sudden hearing loss, visual changes, significant drops in blood pressure, or prolonged erections lasting beyond the four-hour window. Alert your doctor immediately if you experience any severe side effects, particularly if you have pre-existing heart conditions, as this could lead to serious complications such as irregular heartbeat, heart attack, or stroke. Ensure that you discuss your complete medical history with your Walgreens healthcare provider to determine the safety and appropriateness of using Sildenafil in your situation.

Sildenafil vs. Tadalafil: What’s the difference?
Both Sildenafil (the generic form of Viagra) and Tadalafil (the generic form of Cialis) are categorized as phosphodiesterase type 5 inhibitors. They function similarly to combat erectile dysfunction. Each can be taken as needed within the stipulated timeframe of approximately 30 minutes before sexual activity, but Tadalafil tends to have a longer duration in the body.

Vardenafil is recommended to be taken approximately one hour prior to sexual activity, while Sildenafil can be ingested as early as 30 minutes and up to four hours beforehand. Although both medications have comparable durations of action, they should never be taken at the same time. Always consult with your healthcare provider to choose the right medication for your needs.
