Understanding Sildenafil
What is Sildenafil?
Sildenafil, the active component commonly known as generic Viagra, represents an oral prescription medication employed in the management of male sexual dysfunction, more clinically referred to as impotence or erectile dysfunction (ED). This medication, conveniently administered as a tablet, is intended to be taken prior to engaging in sexual activity, with a recommended frequency of no more than once within a span of 24 hours. In addition to its primary use in addressing erectile dysfunction, sildenafil also has therapeutic applications in treating pulmonary arterial hypertension (PAH), affecting both male and female patients. It is crucial to note that these distinct formulations should never be combined or substituted for one another, as they serve different medical purposes.
How does sildenafil work?
Sildenafil functions as a phosphodiesterase-5 enzyme (PDE-5) inhibitor, a mechanism that plays a critical role in its effectiveness. When taken in conjunction with sexual stimulation, sildenafil works by promoting an increase in blood flow to the penile region, thereby aiding men in achieving and sustaining an erection. It is important to highlight that sildenafil's efficacy is contingent upon the presence of sexual stimulation and does not initiate an erection on its own.
How to take sildenafil for best results
For optimal results, sildenafil is best consumed approximately one hour prior to planned sexual activity; however, it is flexible enough to be taken any time within the window of 30 minutes to four hours before the intended sexual encounter. Its usage should be on an as-needed basis, and it is paramount that it is not taken more than once in a 24-hour period. Importantly, sildenafil can be administered with or without food, allowing for greater convenience in various situations.
How long does sildenafil take to work?
The onset of sildenafil's effects is typically observed within approximately 60 minutes of consumption. However, it is essential to understand that sildenafil is effective in alleviating erectile dysfunction only when used in conjunction with sexual stimulation. The timing of its action can vary among individuals, so patience may be required to assess its full effectiveness.
How long does sildenafil last?
The duration of effectiveness for erections induced by sildenafil generally ranges from two to four hours. If an erection persists beyond the four-hour mark, it is crucial for patients to seek immediate medical attention to address this potentially serious condition. Prompt action is necessary to avoid complications associated with prolonged erections.
What are the side effects of sildenafil?
Like all pharmaceuticals, sildenafil can lead to the manifestation of side effects, some of which may be of a more serious nature. Commonly reported side effects associated with sildenafil include headache, flushing (characterized by warm redness of the skin in areas such as the face, neck, ears, or chest), nasal congestion, and indigestion. Generally, these side effects are temporary and resolve as the medication's effects diminish. However, should these side effects become bothersome or fail to dissipate, it is advisable to consult with your healthcare provider.
It is essential to seek immediate medical intervention if any severe side effects occur, such as sudden impairments in hearing, visual disturbances (including changes in color perception, blurred vision, or light sensitivity), marked drops in blood pressure, or an erection lasting longer than four hours. Although rare, severe eye problems can occur, potentially leading to alterations in eyesight or even temporary or permanent vision loss. Additionally, sildenafil has been associated, though infrequently, with abnormal heart rhythms, heart attacks, or strokes, especially in individuals with pre-existing cardiovascular conditions. Prior to commencing sildenafil, it is advisable to discuss your complete medical history with your Walgreens healthcare provider to confirm its safety for your individual circumstances.

- Sildenafil vs. tadalafil: What’s the difference?
Both sildenafil (the generic form of Viagra) and tadalafil (the generic form of Cialis) belong to the class of medications known as phosphodiesterase-5 (PDE-5) inhibitors, which function similarly to address erectile dysfunction. Each can be taken as needed prior to sexual activity, but tadalafil may offer a prolonged duration of action compared to sildenafil. As a result, tadalafil features lower strength options that can be taken daily, regardless of sexual activity timing. It is crucial to never combine sildenafil and tadalafil, and a healthcare provider should be consulted to determine which medication aligns best with your needs.
- Sildenafil vs. Vardenafil: What’s the difference?
Sildenafil (the generic version of Viagra) and vardenafil (the generic version of Levitra) are both PDE-5 inhibitors that provide comparable efficacy in treating erectile dysfunction. Vardenafil should be taken one hour before sexual activity, while sildenafil can be administered as early as 30 minutes up to four hours before. The duration of action for both medications is similar, and they are to be used as needed, not to exceed once per day. It is important to avoid taking sildenafil and vardenafil simultaneously. Discuss with your healthcare provider to identify the most appropriate treatment for your specific condition.
