Understanding Sildenafil
What is Sildenafil?
Sildenafil, often referred to as the generic version of Viagra, is a widely prescribed oral medication specifically designed to address male sexual dysfunction, commonly known as impotence or erectile dysfunction (ED). This medication comes in tablet form and is intended to be taken prior to sexual activity, with a maximum recommended frequency of once within a 24-hour period. Additionally, Sildenafil serves another purpose; it is also employed in the treatment of pulmonary arterial hypertension (PAH), which affects blood pressure within the arteries leading to the lungs. It's important to note that the various forms of Sildenafil are not interchangeable and should never be used simultaneously.
How does Sildenafil work?
Sildenafil operates as a phosphodiesterase-5 (PDE-5) enzyme inhibitor. This mechanism facilitates an increase in blood flow to the penis when natural sexual stimulation occurs, thereby helping men to not just achieve an erection but also to maintain it effectively throughout the sexual experience. However, it's crucial to highlight that Sildenafil will not produce an erection in the absence of sexual stimulation.
How to take Sildenafil for best results
For optimal efficacy, it is recommended that Sildenafil be taken approximately one hour prior to engaging in sexual activity. However, it can be consumed at any point between 30 minutes and four hours before sexual engagement. Patients should take it as needed, adhering to the guideline of no more than once every 24 hours. Importantly, Sildenafil can be administered either with or without food, offering flexibility based on personal preference.
How long does Sildenafil take to work?
Sildenafil is effective for improving erectile dysfunction when used in conjunction with sexual stimulation. The onset of action typically occurs within about 60 minutes after ingestion, making timing an essential consideration for its use.
How long does Sildenafil last?
The effects of Sildenafil can last anywhere from two to four hours, allowing for a window of opportunity for intimate activity. It is imperative for patients to seek immediate medical attention if an erection persists beyond four hours, as this condition can indicate a serious underlying issue.
What are the side effects of Sildenafil?
As with all medications, Sildenafil may produce side effects, some of which could be severe. Common adverse reactions associated with Sildenafil include headaches, flushing (characterized by warmth and redness, particularly in the face, neck, ears, or chest), nasal congestion, and indigestion. Fortunately, these side effects are generally temporary and subside as the medication's effects diminish. However, if these issues become bothersome or persist, it is advisable to consult a healthcare provider.
In more serious cases, individuals should seek urgent medical assistance if they experience notable side effects such as sudden hearing loss, vision changes (including color perception alterations, blurred vision, or sensitivity to light), a sudden drop in blood pressure, or an erection lasting longer than four hours. Extremely rare but severe eye conditions have been reported that may result in changes in eyesight, potentially leading to either temporary or permanent vision loss. There exists a risk, albeit minimal, of sildenafil causing irregular heartbeats, heart attacks, or strokes, particularly in those with pre-existing heart conditions. It is crucial for patients to discuss their full medical history with their Walgreens healthcare provider to determine if Sildenafil is a safe option for them.

- Sildenafil vs. Tadalafil: What’s the difference?
Both Sildenafil (generic for Viagra) and Tadalafil (generic for Cialis) function as phosphodiesterase-5 (PDE-5) inhibitors aimed at treating erectile dysfunction. They can both be taken as needed, but it’s important to take them at least 30 minutes before sexual activity, ensuring that they are not used more than once every 24 hours. Tadalafil has a longer duration of action compared to Sildenafil, allowing for lower strength options suitable for daily use, independent of sexual activity timing. It’s crucial to consult your healthcare provider to establish which medication aligns best with your personal health needs.
- Sildenafil vs. Vardenafil: What’s the difference?
Similar to Sildenafil (generic for Viagra), Vardenafil (generic for Levitra) also acts as a PDE-5 inhibitor for the treatment of erectile dysfunction. While Vardenafil is to be taken approximately one hour before engaging in sexual activity, Sildenafil allows for greater flexibility, as it can be taken anywhere from 30 minutes to four hours ahead of time. Both medications are effective for a comparable duration and should follow the same as-needed usage guidelines, with no more than one dose every 24 hours. Sildenafil and Vardenafil should never be taken together. Please consult with your healthcare provider to determine which option is best for you.
