Understanding Sildenafil
What is Sildenafil?
Sildenafil, the generic formulation for Viagra, serves as a prescribed medication that effectively addresses male sexual dysfunction, specifically impotence or erectile dysfunction (ED). It is designed as an oral tablet taken shortly before engaging in sexual activity, with a recommended frequency of no more than once every 24 hours. Beyond its use for erectile dysfunction, sildenafil is also utilized for treating pulmonary arterial hypertension (PAH), a serious condition affecting the arteries in the lungs, and is suitable for both men and women. It is crucial to note that the various forms of sildenafil should never be used interchangeably or combined.
How does sildenafil work?
As a phosphodiesterase-5 enzyme (PDE-5) inhibitor, sildenafil plays a pivotal role in facilitating erectile function. When paired with sexual stimulation, sildenafil enhances blood flow to the penis, thereby assisting men in achieving and maintaining an erection. It is important to highlight that sildenafil requires sexual arousal to be effective and does not produce an erection without it.
How to take sildenafil for best results
For optimal results, sildenafil should be taken about one hour before planned sexual activity, although it can also be taken from 30 minutes to four hours prior. The medication should be used on an as-needed basis, adhering to the limitation of once every 24 hours. Patients can take sildenafil with or without food, allowing for flexibility and ease of scheduling.
How long does sildenafil take to work?
When combined with sexual arousal, sildenafil typically begins to work within approximately 60 minutes. It is essential for users to understand that the medication’s efficacy relies on the presence of sexual stimulation, as it does not initiate an erection independently.
How long does sildenafil last?
The effects of sildenafil can produce erections that last between two to four hours. If an erection persists beyond four hours, it is critical to seek emergency medical attention to avoid potential complications.
What are the side effects of sildenafil?
Like all medications, sildenafil may entail side effects, some of which can be significant. Common side effects include headaches, flushing of the skin (often seen in the face, neck, and chest), nasal congestion, and indigestion; these effects are generally temporary and subside as the drug wears off. However, if these effects become bothersome or do not resolve, it is important to contact your doctor for guidance.
Immediate medical attention should be sought if serious side effects arise such as sudden hearing loss, visual disturbances (including changes in color perception, blurred vision, or light sensitivity), a drastic drop in blood pressure, or an erection lasting over four hours. In rare cases, sildenafil has been associated with severe eye problems that can lead to vision changes, including temporary or permanent loss of sight. Additionally, there is a potential risk of sildenafil inducing abnormal heart rhythms, heart attacks, or strokes, particularly in individuals with pre-existing heart conditions. Always discuss your full medical history with your Walgreens healthcare provider to ensure sildenafil is safe for you.

While vardenafil should be taken one hour before sexual activity, sildenafil can be ingested as early as 30 minutes and up to four hours prior. Both medications have comparable durations of effectiveness but should be taken on an as-needed basis, ensuring usage does not exceed once every 24 hours. Both sildenafil and vardenafil are available in oral tablet form for erectile dysfunction treatment. Avoid taking these medications simultaneously. Consult your healthcare provider to determine which option is most appropriate for your condition.
