Understanding Sildenafil
What is Sildenafil?
Sildenafil, the generic version of Viagra, is an oral prescription medication that has been specifically formulated to treat male sexual dysfunction, a condition often referred to as impotence or erectile dysfunction (ED). Administered as a tablet before engaging in sexual activity, Sildenafil should not be taken more than once within a 24-hour period. In addition to its use in addressing erectile dysfunction, Sildenafil is also available in various formulations, and is utilized in the treatment of pulmonary arterial hypertension (PAH) – a serious condition affecting blood flow in the lungs – applicable to both men and women. It's crucial to note that these various formulations should not be combined or substituted for one another without medical guidance.
How does Sildenafil work?
This medication acts as a phosphodiesterase-5 enzyme (PDE-5) inhibitor. When combined with sexual arousal, Sildenafil promotes increased blood flow to the penile area, thereby assisting men in both achieving and sustaining an erection. However, it's important to clarify that Sildenafil does not initiate an erection on its own and is dependent on sexual stimulation to take effect.
How to take Sildenafil for best results
To maximize its efficacy, Sildenafil is ideally taken about one hour prior to anticipated sexual activity, although it can be effective if administered anywhere from 30 minutes to four hours beforehand. The medication should be taken on an as-needed basis, but again, no more frequently than once every 24 hours. Patients are advised that it can be consumed with or without food, which offers flexibility in its administration.
How long does Sildenafil take to work?
For it to effectively combat erectile dysfunction, the use of Sildenafil must be paired with sexual arousal. Typically, its effects begin to manifest within approximately 60 minutes of ingestion. However, individual responses may vary based on several factors, including overall health and metabolic rate.
How long does Sildenafil last?
The duration of an erection achieved with the help of Sildenafil can persist for anywhere between two to four hours. It is imperative for patients to seek immediate medical attention if an erection endures beyond the four-hour mark, as this could signify a serious medical condition known as priapism.
What are the side effects of Sildenafil?
As with all medications, Sildenafil can produce side effects – some of which may necessitate medical intervention. Among the most commonly reported side effects associated with its use for erectile dysfunction are headaches, flushing (characterized by a warm, red appearance typically affecting the face, neck, ears, or chest), nasal congestion, and indigestion. These side effects are generally transient and will typically diminish as the effects of the medication subside. However, patients should promptly contact their healthcare provider if these side effects become bothersome or persist longer than expected.
Urgent medical attention should be sought in the event of serious side effects such as sudden hearing loss or impairment, visual disturbances (which may include changes in color perception, blurred vision, or heightened sensitivity to light), a significant drop in blood pressure, or an erection lasting longer than four hours. It's worth noting that rare but severe eye problems associated with Sildenafil use may contribute to a shift in visual perception, with the potential for temporary or permanent vision loss in certain cases. Additionally, in some rare instances, Sildenafil has been linked to abnormalities in heart rhythm, heart attacks, or strokes, particularly among individuals with pre-existing cardiovascular conditions. It is vital for patients to have an open discussion with their Walgreens healthcare provider regarding their complete medical history to ensure that Sildenafil is an appropriate choice.

- Sildenafil vs. Tadalafil: What’s the difference?
Both Sildenafil (the generic for Viagra) and Tadalafil (the generic for Cialis) belong to the category of phosphodiesterase-5 enzyme (PDE-5) inhibitors and function in a similar manner to alleviate erectile dysfunction. Both medications can be taken as needed, with the requirement of at least 30 minutes before anticipated sexual activity, with a limit of once every 24 hours. Tadalafil, however, may exhibit a longer duration of action compared to Sildenafil, leading to lower strength options for Tadalafil that can be administered daily, regardless of sexual activity timing. It is essential to avoid concurrent use of Sildenafil and Tadalafil. Consulting your healthcare provider will help determine which medication aligns best with your needs.
- Sildenafil vs. Vardenafil: What’s the difference?
Sildenafil (generic for Viagra) and Vardenafil (generic for Levitra) are both classified as phosphodiesterase-5 enzyme inhibitors that function similarly in treating erectile dysfunction. Vardenafil should ideally be taken one hour prior to engaging in sexual activity, while Sildenafil can be taken as soon as 30 minutes and up to four hours prior. Both medications maintain comparable durations of efficacy, and they should be utilized on an as-needed basis, not exceeding once every 24 hours. It is critical to refrain from administering both Sildenafil and Vardenafil simultaneously. Discussing your medication options with a healthcare provider will aid in making an informed decision regarding which one is appropriate for your treatment regimen.
