Understanding Sildenafil
What is Sildenafil?
Sildenafil, known more commonly as the generic version of Viagra, is an oral prescription medication that has been widely used to effectively treat male sexual dysfunction, also referred to as impotence or erectile dysfunction (ED). Typically, this medication is administered as a tablet that should be taken before engaging in sexual activity, with the instructions advising no more than one dose within a 24-hour period. Additionally, sildenafil is not limited to the treatment of ED; it is also prescribed in different formulations for the management of high blood pressure in the pulmonary arteries, a condition known as pulmonary arterial hypertension (PAH), which can affect both men and women. Importantly, these varying formulations should never be mixed or used interchangeably.
How does sildenafil work?
As a phosphodiesterase-5 enzyme (PDE-5) inhibitor, sildenafil operates by enhancing blood flow to the penis in response to sexual arousal. When taken, it works synergistically with sexual stimulation to promote increased blood circulation, which facilitates the ability to achieve and sustain an erection. It is crucial to understand that sildenafil does not induce an erection by itself; sexual stimulation is a necessary component for its efficacy.
How to take sildenafil for best results
For optimal results, sildenafil should ideally be taken approximately one hour prior to anticipated sexual activity. However, it is flexible in its administration and can be effectively taken any time between 30 minutes to four hours before engaging in sexual intercourse. It is designed for use as needed, with the caution of not exceeding one dose within a 24-hour timeframe. Patients have the option to take sildenafil with food or on an empty stomach, depending on their preference.
How long does sildenafil take to work?
The effectiveness of sildenafil in treating erectile dysfunction is contingent upon sexual stimulation, as it only initiates its action in such circumstances. Most users can expect to feel the effects begin roughly 60 minutes after taking the medication.
How long does sildenafil last?
The duration of an erection facilitated by sildenafil typically lasts between two to four hours. It is important that patients seek immediate medical attention if an erection persists for longer than four hours, as this could indicate a serious condition requiring urgent care.
What are the side effects of sildenafil?
As with all medications, sildenafil is not without its potential side effects, some of which can be more severe in nature. Among the commonly reported side effects associated with sildenafil when treating erectile dysfunction are headache, flushing (characterized by a warm and red appearance of the skin, commonly affecting the face, neck, ears, or chest), nasal congestion, and digestive discomfort. These side effects are generally short-lived and should diminish as the medication effects wane. Patients are encouraged to consult their healthcare provider if they experience any side effects that are persistent or troubling.
In rare instances, patients may experience more serious side effects, which necessitate immediate medical intervention. These can include sudden loss of hearing or impairment, visual disturbances (such as alterations in color perception, blurred vision, or increased sensitivity to light), a drastic drop in blood pressure, or an erection that lasts beyond four hours. There have been uncommon but serious ocular complications reported, potentially leading to vision changes, including temporary or permanent loss of sight. Additionally, sildenafil may rarely induce irregular heartbeat, heart attack, or stroke, particularly in individuals with pre-existing heart conditions. Therefore, it is crucial to discuss your complete medical history with your Walgreens healthcare provider to determine if sildenafil is an appropriate option for you.

- Sildenafil vs. tadalafil: What’s the difference?
Sildenafil (the generic form of Viagra) and tadalafil (the generic form of Cialis) are both classified as phosphodiesterase-5 enzyme (PDE-5) inhibitors and function similarly in the treatment of erectile dysfunction. Both medications can be taken as needed, ideally at least 30 minutes prior to sexual activity, but must not exceed one dose within a 24-hour period. Notably, tadalafil may remain effective in the body for a longer duration compared to sildenafil, leading to the availability of lower strength tadalafil options that can be taken daily, irrespective of the timing of sexual activity. Importantly, sildenafil and tadalafil should not be taken concurrently; it is essential to consult with your healthcare provider to ascertain which medication may be the best fit for your specific situation.
- Sildenafil vs. Vardenafil: What’s the difference?
Sildenafil (the generic version of Viagra) and vardenafil (the generic version of Levitra) are also classified as phosphodiesterase-5 enzyme inhibitors and share similar mechanisms for treating erectile dysfunction. While vardenafil should be taken an hour prior to sexual activity, sildenafil offers greater flexibility, as it can be taken as early as 30 minutes up to four hours before sexual engagement. Both sildenafil and vardenafil exert effects for approximately the same duration and are intended for use on an as-needed basis, but it is important to remember that neither should be taken more than once within a 24-hour period. Additionally, both sildenafil and vardenafil are available in oral tablet forms for the management of erectile dysfunction. Patients should consult with their healthcare provider to determine the most suitable medication tailored to their needs.
