Understanding Sildenafil
-
What is Sildenafil?
Sildenafil, the generic counterpart to the well-known Viagra, is an oral prescription medication specifically designed to address male sexual dysfunction, often referred to as impotence or erectile dysfunction (ED). This medication is typically administered in tablet form and is intended to be consumed prior to engaging in sexual activity, with a recommended usage frequency not exceeding once within a 24-hour period. Beyond its primary usage for erectile dysfunction, Sildenafil is also available in various other formulations and is utilized for managing high blood pressure in the pulmonary arteries of the lungs, a condition known as pulmonary arterial hypertension (PAH), affecting both men and women. It’s critical to note that these distinct product types should never be utilized concurrently nor should one be seen as an alternative to the other.
-
How does sildenafil work?
Sildenafil acts as a phosphodiesterase-5 enzyme (PDE-5) inhibitor. When paired with sexual stimulation, the medication promotes increased blood flow to the penis, enabling men to achieve and sustain an erection. It is important to understand that Sildenafil will not produce an erection without sexual arousal.
-
How to take sildenafil for best results
For optimal outcomes, Sildenafil is best ingested approximately one hour prior to engaging in sexual activity. Nevertheless, it can be taken anytime within a window ranging from 30 minutes to four hours before intended sexual engagement. It is to be taken as needed, but not exceeding the limit of once per 24-hour period. Patients may take Sildenafil with or without food, providing flexibility in administration.
-
How long does sildenafil take to work?
For Sildenafil to effectively mitigate erectile dysfunction, it must be utilized in conjunction with sexual stimulation. The onset of its effectiveness typically occurs within approximately 60 minutes of consumption.
-
How long does sildenafil last?
The effects of Sildenafil can facilitate erections lasting anywhere from two to four hours. It is vital for users to seek immediate medical attention if they experience an erection persisting beyond four hours, as this can lead to serious complications.
-
What are the side effects of sildenafil?
As with any medication, Sildenafil can induce side effects, some of which may be severe. Commonly reported side effects include headaches, facial flushing (characterized by warm, red skin particularly around the face, neck, ears, or chest), nasal congestion, and instances of indigestion. Generally, these side effects are temporary and should dissipate as the medication is metabolized and its effects wear off. Should these effects prove bothersome or persist, it is advised to consult your healthcare provider.
It’s crucial to seek immediate medical attention upon noticing serious side effects such as sudden hearing loss or impairment, visual disturbances (including alterations in vision color, blurred vision, or light sensitivity), a rapid decline in blood pressure, or an erection lasting more than four hours. Rare occurrences of serious ocular issues have been documented, which can lead to enduring changes in eyesight or even temporary or permanent vision loss. In extremely rare cases, Sildenafil might trigger irregular heart rhythms, heart attacks, or strokes, particularly in individuals with pre-existing heart conditions. It is imperative to have a thorough discussion with your Walgreens healthcare provider regarding your complete medical history to assess the safety of Sildenafil for your personal use.
