Understanding Sildenafil
-
What is Sildenafil?
Sildenafil is commonly known as the generic version of Viagra, and it is a prescription medication prescribed orally to treat male sexual dysfunction, which is referred to as impotence or erectile dysfunction (ED). This medication comes in tablet form and should be used prior to engaging in sexual activity, not exceeding one dose within a 24-hour period. Additionally, sildenafil is utilized in various formulations for the treatment of pulmonary arterial hypertension (PAH), a condition characterized by elevated blood pressure in the arteries of the lungs, affecting both men and women. It is crucial to note that these different formulations should never be used interchangeably or combined.
-
How does sildenafil work?
Sildenafil functions as a phosphodiesterase-5 enzyme (PDE-5) inhibitor. When accompanied by sexual stimulation, it promotes increased blood flow to the penis, facilitating the ability for men to achieve and sustain an erection. It is important to highlight that sildenafil is ineffective in the absence of sexual stimulation, meaning that it does not induce an erection on its own.
-
How to take sildenafil for best results
For optimal results, sildenafil should be taken approximately one hour before engaging in sexual activity; however, it can be ingested anywhere from 30 minutes to four hours prior. This medication is intended for use as needed, but it should not be taken more than once within a 24-hour timeframe. Users can take sildenafil either on a full or empty stomach, providing flexibility in its administration.
-
How long does sildenafil take to work?
It’s essential to understand that sildenafil only enhances erectile dysfunction when used in conjunction with sexual stimulation. The onset of its effects typically occurs within approximately 60 minutes after taking the medication.
-
How long does sildenafil last?
The duration of erections attained from sildenafil may last anywhere from two to four hours. Patients should be advised to seek immediate medical attention if an erection persists for longer than four hours, as this could indicate a serious condition known as priapism.
-
What are the side effects of sildenafil?
Like any medication, sildenafil can lead to various side effects, some of which might require medical attention. Common side effects include headache, flushing (a warm, red sensation on the face, neck, or chest), nasal congestion, and upset stomach. Typically, these side effects are temporary and will resolve as the medication wears off. If these effects prove to be bothersome or persist, it is advisable to consult with a healthcare provider.
Seek immediate medical assistance if you experience severe side effects such as sudden hearing loss, vision changes (like color alterations, blurred vision, or light sensitivity), a significant drop in blood pressure, or an erection lasting longer than four hours. There have been rare instances of serious eye conditions leading to changes in eyesight, including temporary or permanent vision loss. In rare occurrences, sildenafil may lead to heart-related issues such as abnormal heart rhythms, heart attacks, or strokes, particularly in individuals with pre-existing heart conditions. It is vital to discuss your complete medical history with your Walgreens healthcare provider to ensure sildenafil is appropriate for your use.

Sildenafil vs. tadalafil: What’s the difference?
Both sildenafil (generic for Viagra) and tadalafil (generic for Cialis) function as phosphodiesterase-5 enzyme (PDE-5) inhibitors designed to treat erectile dysfunction. Both medications should be taken as needed at least 30 minutes before sexual activity, not exceeding one dose every 24 hours. Tadalafil may remain effective in your system longer than sildenafil. Consequently, lower-strength tadalafil options exist that can be taken daily regardless of sexual activity timing. It’s critical to never combine sildenafil and tadalafil together. Always consult your healthcare provider to determine which medication aligns best with your health needs.

Sildenafil vs. Vardenafil: What’s the difference?
Sildenafil (the generic form of Viagra) and vardenafil (the generic version of Levitra) share the same functional mechanism as phosphodiesterase-5 enzyme (PDE-5) inhibitors; both are effective for treating erectile dysfunction. Vardenafil is recommended to be taken one hour prior to sexual activity, whereas sildenafil can be consumed as soon as 30 minutes and up to four hours before engaging in sexual activity. While both last a similar duration, they should be consumed only as needed—not exceeding once every 24 hours. Remember, combining sildenafil and vardenafil is contraindicated. Speak with your healthcare provider to identify which medication suits your requirements.
