Understanding Sildenafil
What is Sildenafil?
Sildenafil, which is the generic form of Viagra, is an oral medication that is available only by prescription and is primarily used for treating male sexual dysfunction, commonly referred to as impotence or erectile dysfunction (ED). This medication is designed to be taken prior to engaging in sexual activity, with a maximum dosage frequency of once every 24 hours. Beyond its use for ED, Sildenafil is also prescribed in other formulations for the management of pulmonary arterial hypertension (PAH), a serious condition affecting the blood vessels in the lungs, impacting both men and women. It is crucial to understand that these various forms of Sildenafil should not be mixed or used interchangeably.
How does sildenafil work?
Sildenafil functions as a phosphodiesterase-5 (PDE-5) enzyme inhibitor. When sexual stimulation occurs, Sildenafil enhances blood flow to the penis, facilitating the ability for men to achieve and sustain an erection. It is important to note that Sildenafil will not induce an erection without accompanying sexual stimulation.
How to take sildenafil for best results
To optimize effectiveness, Sildenafil should be administered approximately one hour before sexual activity; however, it may also be taken anytime between 30 minutes and four hours prior to sexual encounters. It should be used as needed, ensuring it is not taken more than once every 24 hours. Additionally, Sildenafil can be ingested with or without food, which allows for flexibility in its administration.
How long does sildenafil take to work?
Sildenafil's effectiveness in addressing erectile dysfunction hinges on sexual stimulation, initiating its action in about 60 minutes post-ingestion. Each individual's response time may vary, but this general timeline provides a framework for planning.
How long does sildenafil last?
The duration of an erection facilitated by Sildenafil can extend from two to four hours following intake. Should an erection persist beyond four hours, it is imperative to seek immediate medical assistance to prevent potential complications.
What are the side effects of sildenafil?
As with any medication, Sildenafil may result in side effects, some of which could be severe. Common side effects experienced by users include headaches, facial flushing, nasal congestion, and indigestion. Typically, these side effects are temporary and resolve as the medication's effects diminish. However, patients are advised to consult their healthcare provider if side effects persist or cause discomfort.
Urgent medical attention should be sought if serious adverse reactions occur, such as sudden hearing loss or impairment, visual problems (including color vision changes, blurred vision, or light sensitivity), significant drops in blood pressure, or a prolonged erection lasting more than four hours. Rarely, Sildenafil is associated with serious eye complications that can lead to changes in vision, potentially resulting in temporary or even permanent vision loss. Moreover, cardiovascular events like abnormal heart rhythms, heart attacks, or strokes have been reported, particularly in individuals with pre-existing heart conditions. Always engage in thorough discussions with your Walgreens healthcare provider regarding your medical history to ascertain that Sildenafil is a safe option for your health needs.

Both medications can be consumed as needed, ideally 30 minutes prior to sexual activity, with a maximum frequency of once every 24 hours. Tadalafil exhibits a longer duration of action compared to Sildenafil, which permits lower strength Tadalafil formulations to be taken daily irrespective of sexual activity timing.

While vardenafil should be taken one hour before sexual activity, Sildenafil allows for administration as early as 30 minutes before and up to four hours before sexual engagement. The duration of effectiveness for both medications is comparable, and they should not be ingested concurrently. For specific guidance on which medication suits your needs, please discuss with your healthcare provider.
