Understanding Sildenafil
What is Sildenafil?
Sildenafil, the generic version of Viagra, is an oral prescription medication specifically designed for the treatment of male sexual dysfunction, which is commonly referred to as impotence or erectile dysfunction (ED). It is formulated as a tablet that should be taken before engaging in sexual activity, ensuring that it is not consumed more than once within a 24-hour period. Additionally, sildenafil is available in various forms and also serves the purpose of treating a serious condition known as pulmonary arterial hypertension (PAH), affecting blood pressure in the pulmonary arteries in both males and females. It’s crucial to understand that these different forms of the medication should not be utilized interchangeably, nor should they be substituted for one another.
How does sildenafil work?
Sildenafil functions as a phosphodiesterase-5 enzyme (PDE-5) inhibitor. When combined with sexual stimulation, sildenafil facilitates an increase in blood flow to the penis, assisting men in both achieving and sustaining an erection. It's important to note that sildenafil will not have any effect unless accompanied by sexual stimulation; thus, it is essential for the patient to be adequately aroused for the medication to be effective.
How to take sildenafil for best results
For optimal results, sildenafil should ideally be administered approximately one hour prior to any sexual activity, although its intake can take place anytime within a window of 30 minutes to four hours beforehand. The medication should be used as needed, ensuring that it is not taken more than once every 24 hours. Sildenafil can be ingested either on a full stomach or on an empty stomach, providing flexibility in its consumption.
How long does sildenafil take to work?
The efficacy of sildenafil in addressing erectile dysfunction is contingent upon the presence of sexual stimulation. On average, it begins to take effect approximately 60 minutes after ingestion. This timeline may differ based on individual metabolic factors and the specifics of the situation surrounding its use.
How long does sildenafil last?
The effects of an erection facilitated by sildenafil can persist for a duration of two to four hours. In the event that an erection exceeds four hours, it is imperative that patients seek immediate medical attention to avoid potential complications.
What are the side effects of sildenafil?
As with any medication, sildenafil possesses the potential to induce side effects, some of which might be severe. Common adverse effects associated with sildenafil for erectile dysfunction include headache, flushing (characterized as warm, red skin, typically affecting the face, neck, ears or chest), nasal congestion, and indigestion. These side effects are usually transient and should dissipate after the medication has been metabolized. If patients find these effects to be disruptive or persistent, it is important to contact their healthcare provider for further advice.
In rare instances, sildenafil may lead to more serious side effects, including sudden hearing loss, visual disturbances (which may manifest as color changes, blurriness, or sensitivity to light), a dramatic drop in blood pressure, or an erection lasting longer than four hours. There have been rare cases of serious eye complications that could potentially lead to changes in vision, including, but not limited to, temporary or permanent vision loss. Furthermore, sildenafil may rarely trigger abnormal heartbeat, heart attacks, or strokes, particularly among individuals with pre-existing heart conditions. Therefore, thorough discussions about one's medical history with a Walgreens healthcare provider is essential to confirm that sildenafil is a safe option.

- Sildenafil vs. tadalafil: What’s the difference?
Both sildenafil (the generic for Viagra) and tadalafil (the generic for Cialis) are classified as phosphodiesterase-5 enzyme (PDE-5) inhibitors that function similarly in treating erectile dysfunction. Each medication can be taken as needed at least 30 minutes before sexual activity, but with a cap of once every 24-hour period. Interestingly, tadalafil is known to remain active in the body for a longer duration compared to sildenafil. Consequently, there are lower strength tadalafil options available that can be taken daily on a regular schedule, regardless of the timing related to sexual activity. It is crucial to understand that sildenafil and tadalafil must never be consumed concurrently. Engagement with a healthcare provider is vital to establish which medication would be the better fit based on individual health profiles.
- Sildenafil vs. Vardenafil: What’s the difference?
Sildenafil (the generic for Viagra) and vardenafil (the generic for Levitra) are both PDE-5 inhibitors designed for treating erectile dysfunction. Notably, while vardenafil should be taken one hour before engaging in sexual activity, sildenafil can be ingested as early as 30 minutes to a maximum of four hours prior. Their effects last for an approximately similar duration in the body, and they are to be taken as needed, ensuring that usage does not exceed once every 24 hours. It is essential to note that sildenafil and vardenafil should never be taken at the same time. Consulting with a healthcare provider is recommended to determine which medication aligns best with your health requirements.
