Understanding Sildenafil
-
What is Sildenafil?
Sildenafil, commonly referred to as the generic equivalent of Viagra, is an effective oral prescription medication specifically designed to treat male sexual dysfunction, which is often medically termed impotence or erectile dysfunction (ED). This medication is intended to be taken in tablet form shortly before engaging in sexual activity, with the recommendation that it should not be consumed more than once every 24 hours. In addition to its role in addressing erectile dysfunction, Sildenafil is also prescribed for other medical conditions, one of which includes managing high blood pressure in the pulmonary arteries, a condition known as pulmonary arterial hypertension (PAH). It is important to note that these different formulations of Sildenafil should never be mixed, nor should they be used interchangeably, as they cater to varying health needs and conditions.
-
How does Sildenafil work?
The mechanism of action of Sildenafil involves its classification as a phosphodiesterase-5 enzyme (PDE-5) inhibitor. When taken in conjunction with sexual arousal, Sildenafil facilitates increased blood flow to the erectile tissues of the penis, thereby enabling men to achieve and sustain an erection. It is essential to understand that Sildenafil does require sexual stimulation to be effective and will not induce an erection in the absence of such stimuli.
-
How to take Sildenafil for best results
For optimal effectiveness, it is advised that Sildenafil be taken approximately one hour before the anticipated sexual encounter. However, this medication can be ingested at various time frames ranging from as little as 30 minutes to as much as four hours prior to engaging in sexual activity. Sildenafil is designed to be taken as needed, but no more frequently than once in a 24-hour period. Additionally, it can be taken with food or on an empty stomach, making it a flexible option for users.
-
How long does Sildenafil take to work?
When used appropriately and in conjunction with sexual stimulation, Sildenafil typically begins to take effect approximately one hour after ingestion. This time frame can vary between individuals, but it is generally effective for enhancing erectile function within this period.
-
How long does Sildenafil last?
The duration of erections achieved with the aid of Sildenafil can last anywhere from two to four hours. If an erection persists for longer than four hours, it is imperative to seek immediate medical assistance to prevent potential complications.
-
What are the side effects of Sildenafil?
As with any medication, Sildenafil can produce side effects, some of which may be serious. Common side effects associated with the use of Sildenafil for erectile dysfunction include headaches, flushing (characterized by warmth and redness of the skin, particularly on the face, neck, and chest), nasal congestion, and indigestion. These side effects are generally temporary and tend to subside after the effects of the medication diminish. It is advisable to consult with your healthcare provider if these side effects become bothersome or persist longer than expected.
In rare instances, serious adverse reactions may occur, such as sudden hearing loss, visual disturbances (which can include changes in color vision, blurred vision, or light sensitivity), a dramatic drop in blood pressure, or an erection lasting more than four hours. There have been recorded instances of rare but serious eye issues that could result in changes to one’s eyesight, which can sometimes lead to temporary or permanent vision loss. Additionally, Sildenafil can infrequently cause cardiac issues like abnormal heartbeat, heart attack, or stroke, especially in individuals with pre-existing heart conditions. Always disclose your complete medical history to your Walgreens healthcare provider to ensure that Sildenafil is a suitable medication for you.

Sildenafil vs. Tadalafil: What’s the difference?
Sildenafil (the generic form of Viagra) and Tadalafil (the generic form of Cialis) both belong to the class of medications known as phosphodiesterase-5 (PDE-5) inhibitors. They function similarly to address erectile dysfunction but may differ in terms of duration and usage guidelines. Both medications are to be taken as needed, ideally at least 30 minutes prior to sexual activity, and should not be taken more than once within a 24-hour period. Tadalafil may remain effective in your body longer than Sildenafil, leading to the availability of lower-strength tadalafil alternatives that can be taken daily, whether or not sexual activity is anticipated. It is critical to consult your healthcare provider to choose the most appropriate medication for your situation.

It is important to note that Sildenafil and Vardenafil should never be taken concurrently. Consult with your healthcare provider to determine which medication best meets your health needs.
