Understanding Sildenafil
What is Sildenafil?
Sildenafil, the generic version of the brand name Viagra, is a vital oral prescription medication specifically designed to effectively treat male sexual dysfunction, commonly referred to as impotence or erectile dysfunction (ED). This medication comes in the form of tablets and is intended to be taken prior to anticipated sexual activity, with a maximum frequency of one tablet every 24 hours. In addition to its primary use for erectile dysfunction, sildenafil is also available in alternative formulations and is indicated for the treatment of pulmonary arterial hypertension (PAH), a condition characterized by high blood pressure in the arteries supplying the lungs. It is essential to note that these two forms of sildenafil are not interchangeable or to be used simultaneously.
How does sildenafil work?
The mechanism of action of sildenafil involves its role as a phosphodiesterase type 5 (PDE-5) enzyme inhibitor. When sexual stimulation occurs, sildenafil effectively enhances blood flow to the penis, thereby assisting men in achieving and sustaining an erection. It is crucial to understand that sildenafil requires sexual arousal and stimulation in order to exert its effects; it does not work in the absence of these triggers.
How to take sildenafil for best results
For optimal results, sildenafil should ideally be taken about one hour prior to engaging in sexual activity. However, it is acceptable to take it at any time within a window of 30 minutes to four hours leading up to the event. The medication should be taken on an as-needed basis, but not exceeding once every 24 hours. Importantly, sildenafil can be taken either with or without food, providing flexibility for users regarding meal timing.
How long does sildenafil take to work?
The onset of action for sildenafil is approximately 60 minutes, but it is important to highlight that it only assists in ameliorating erectile dysfunction when there is concurrent sexual stimulation. Therefore, the timing of ingestion in relation to sexual activity can influence its effectiveness.
How long does sildenafil last?
The duration of effect for sildenafil typically ranges from two to four hours, during which time erections can be achieved. If an erection persists for longer than four hours, it is imperative to seek emergency medical attention, as this condition could indicate a serious complication known as priapism.
What are the side effects of sildenafil?
Like all medications, sildenafil may lead to side effects, some of which could be serious. Commonly reported side effects associated with sildenafil use for erectile dysfunction include headaches, flushing (which presents as warm, red skin, often localized to the face, neck, ears, or chest), nasal congestion, and digestive disturbances such as indigestion. These side effects are typically transient and are expected to resolve as the medication exits the system. It is advisable to reach out to your healthcare provider if these adverse effects prove uncomfortable or persist beyond an expected duration.
Immediate medical intervention should be sought if serious side effects occur, including sudden loss of hearing, visual disturbances (such as changes in color perception, blurred vision, or increased light sensitivity), a sudden drop in blood pressure, or an erection lasting longer than four hours. While rare, serious eye-related issues may also arise, potentially leading to alterations in vision, including temporary or even permanent vision loss. Additionally, sildenafil could infrequently trigger irregular heartbeats, heart attacks, or strokes, particularly among individuals with pre-existing cardiovascular conditions. It is crucial to provide your Walgreens healthcare provider with a comprehensive medical history to ascertain whether sildenafil is safe for your use.
