Understanding Sildenafil
What is Sildenafil?
Sildenafil, the generic version of Viagra, is a widely prescribed oral medication designed specifically to treat male sexual dysfunction, commonly referred to as impotence or erectile dysfunction (ED). This medication is typically administered in a tablet form and is intended to be taken before engaging in sexual activity, with the recommendation not to exceed one dosage within a 24-hour period. Additionally, sildenafil is available in various formulations and has applications beyond erectile dysfunction; it is also prescribed for managing pulmonary arterial hypertension (PAH), a condition characterized by high blood pressure in the arteries that supply the lungs, affecting both men and women. It’s important to note that different formulations should not be combined or used interchangeably, as this could lead to adverse effects or diminished efficacy of treatment.
How does sildenafil work?
Sildenafil functions as a phosphodiesterase-5 (PDE-5) enzyme inhibitor. When paired with sexual stimulation, sildenafil promotes increased blood flow to the penis, assisting men in both achieving and sustaining an erection. It is crucial to emphasize that sildenafil does not produce any effects in the absence of sexual arousal or stimulation, highlighting the necessity of psychological and physical involvement during its use.
How to take sildenafil for best results
For optimal outcomes, sildenafil is best ingested approximately one hour prior to planned sexual activity. However, it can also be effectively taken at any point between 30 minutes to four hours before engaging in intimacy. This medication is intended for as-needed use, with a maximum limit of one tablet per day. Patients may take sildenafil with or without food, although consumption of high-fat meals may delay its effectiveness.
How long does sildenafil take to work?
Sildenafil is designed to improve erectile dysfunction through the combination with sexual stimulation. Generally, it begins to exert its effects within roughly 60 minutes of administration, thereby enabling the user to engage in sexual activity at their desired time.
How long does sildenafil last?
The duration of erections facilitated by sildenafil typically spans from two to four hours. In the event that an erection persists beyond four hours, it is imperative that the individual seeks immediate medical attention to avoid potential complications.
What are the side effects of sildenafil?
Like all pharmaceutical agents, sildenafil can give rise to side effects, some of which may be significant. Commonly reported side effects include headaches, facial flushing (a sensation of warmth and redness in the skin, especially on the cheeks and neck), nasal congestion, and dyspepsia. These symptoms are generally transient and should resolve as the medication's effects wane. Should any side effects prove persistent or bothersome, it is advisable to consult with your physician for further guidance.
Seek urgent medical assistance if you experience severe side effects such as sudden hearing loss, visual disturbances including changes in color perception, blurred vision, heightened sensitivity to light, a sudden drop in blood pressure, or an erection lasting more than four hours. Rarely, sildenafil may also induce serious cardiovascular incidents, including arrhythmias, heart attacks or strokes, particularly in individuals with pre-existing cardiovascular conditions. Therefore, discussing your complete medical history with your Walgreens healthcare provider is essential to determine whether sildenafil is a suitable option for you.

- Sildenafil vs. tadalafil: What’s the difference?
Both sildenafil (the generic form of Viagra) and tadalafil (the generic form of Cialis) are phosphodiesterase-5 enzyme (PDE-5) inhibitors that function in a similar manner to treat erectile dysfunction. Each can be taken on an as-needed basis at least 30 minutes before sexual activity, with a limit of no more than once every 24 hours. However, tadalafil may remain effective for a longer duration in the body compared to sildenafil, which may lead to the availability of lower strength tadalafil options designed for daily use regardless of sexual activity timing. It is important to never combine sildenafil and tadalafil in one dose. Consult your healthcare provider to figure out which option is the most suitable for your individual situation.
- Sildenafil vs. Vardenafil: What’s the difference?
Sildenafil (generic for Viagra) and vardenafil (generic for Levitra) are both phosphodiesterase-5 inhibitors designed to assist in the treatment of erectile dysfunction. The administration of vardenafil is advised to occur approximately one hour before sexual activity, while sildenafil can be taken as soon as 30 minutes prior and up to four hours before the act. Both medications exhibit similar duration of action in the body and should be used as needed, with a restriction of one dose within a 24-hour period. It is crucial not to co-administer sildenafil and vardenafil. Discussing with your healthcare provider which medication best suits your circumstances is strongly encouraged.
