Understanding Sildenafil
What is Sildenafil?
Sildenafil, the generic version of Viagra, is an effective oral prescription medication specifically designed to treat male sexual dysfunction, which is clinically recognized as impotence or erectile dysfunction (ED). It comes in tablet form, and for optimal results, it should be taken prior to engaging in sexual activity, but no more than once every 24 hours. Additionally, sildenafil is available in various formulations and is utilized for treating pulmonary arterial hypertension (PAH), a condition characterized by high blood pressure in the arteries of the lungs affecting both men and women. It is crucial to understand that these different product forms should not be combined or used interchangeably.
How does sildenafil work?
The mechanism of action of sildenafil involves its role as a phosphodiesterase-5 enzyme (PDE-5) inhibitor. When accompanied by sexual stimulation, sildenafil enhances blood flow to the penis, assisting men in achieving and sustaining an erection. It is important to note that sildenafil does not elicit any effects unless sexual stimulation is present, emphasizing the role of psychological arousal in its efficacy.
How to take sildenafil for best results
To attain the maximum benefits from sildenafil, it is recommended to take the medication approximately one hour before engaging in sexual activity; however, it can also be taken at any time within the range of 30 minutes to four hours prior to the anticipated event. As sildenafil is prescribed on an as-needed basis, it should not be consumed more than once every 24 hours. Patients may take sildenafil with or without food, which allows for flexibility in its administration.
How long does sildenafil take to work?
Sildenafil is clinically proven to only be effective in addressing erectile dysfunction when sexual stimulation is present. It typically begins to act within approximately 60 minutes post-ingestion, allowing men adequate time to prepare for intimate encounters.
How long does sildenafil last?
The effects from sildenafil may enable erections that can last anywhere from two to four hours. Patients are strongly advised to seek immediate medical attention if an erection persists for longer than four hours, as this may indicate a serious medical condition known as priapism that requires urgent intervention.
What are the side effects of sildenafil?
Like any medication, sildenafil can lead to potential side effects, some of which may be serious and necessitate medical attention. Common side effects experienced by users of sildenafil for erectile dysfunction may include headaches, flushing (characterized by warm, red skin often seen on the face, neck, and chest), nasal congestion, and mild indigestion. Most of these side effects are generally temporary and should resolve as the medication's effects diminish. It is advisable to contact your healthcare provider if any of these side effects persist or prove to be bothersome.
Immediate medical assistance should be sought if serious side effects occur, such as sudden hearing or vision impairments, visual disturbances (including color changes, blurred vision, or increased sensitivity to light), a drastic drop in blood pressure, or an erection lasting over four hours. Rare but significant ocular issues may arise, which could potentially lead to a change in vision, including temporary or permanent vision loss. Infrequently, sildenafil may trigger an abnormal heartbeat, heart attack, or stroke, especially in individuals with pre-existing heart conditions. It is essential to discuss your complete medical history with your Walgreens healthcare provider to ensure that sildenafil is a safe treatment option for you.

Both medications can be administered as needed, at least 30 minutes prior to sexual activity, not exceeding once within a 24-hour period. Tadalafil may persist in the system longer than sildenafil, allowing for lower strength options suitable for daily use, irrespective of the timing of sexual activity. It is imperative that sildenafil and tadalafil never be used concurrently. Consultation with your healthcare provider will aid in determining the most appropriate medication based on individual needs.

Sildenafil (the generic for Viagra) and vardenafil (the generic for Levitra) are both PDE-5 inhibitors and are utilized for the treatment of erectile dysfunction. Vardenafil should ideally be taken one hour prior to sexual engagement, whereas sildenafil allows for dosing as early as 30 minutes up to four hours beforehand. Both medications possess a similar duration of action and must be taken on an as-needed basis, with a limitation of once every 24 hours. Both sildenafil and vardenafil come in oral tablet formulations for treating erectile dysfunction, and it is critical to avoid taking these medications simultaneously. Engage with your healthcare provider to establish which treatment option is tailored for you.
