Understanding Viagra for Erectile Dysfunction Treatment
How Viagra Works to Treat Erectile Dysfunction
Viagra belongs to a class of medications called PDE5 inhibitors (phosphodiesterase type 5 inhibitors). The active ingredient, sildenafil citrate, works by blocking the PDE5 enzyme, which increases blood flow to the penis during sexual arousal. It's important to understand that Viagra does not cause automatic erections - sexual stimulation is still required for the medication to be effective. The medication typically begins working within 30-60 minutes of taking it, with effects potentially lasting 4-6 hours. This duration refers to the medication's presence in your system, not the length of an erection.
Available Dosages and Usage Guidelines
Viagra is available in three strengths: 25mg, 50mg, and 100mg tablets. Most men start with the 50mg dose, which can be adjusted up to 100mg or down to 25mg based on effectiveness and tolerability. The maximum recommended frequency is one dose per 24-hour period. For optimal effectiveness, take Viagra approximately 30-60 minutes before planned sexual activity. Food, particularly fatty meals, can delay the medication's onset of action, so taking it on an empty stomach may improve timing. EverydayMeds offers both branded Viagra and generic sildenafil at checkout, allowing patients to choose their preferred option during the ordering process.
Eligibility and Clinical Assessment Requirements
Viagra requires a prescription following consultation with a UK-licensed prescriber. The clinical assessment evaluates several factors including cardiovascular health, current medications, and medical history. Adult men aged 18 and over with erectile dysfunction may be suitable candidates. The assessment helps ensure the medication is safe and appropriate for each individual. EverydayMeds' clinical team reviews each consultation to determine eligibility and recommend the most suitable treatment option, whether branded Viagra or generic sildenafil.
Important Safety Considerations and Contraindications
Certain medical conditions and medications make Viagra unsuitable or potentially dangerous. Men taking nitrate medications such as GTN spray or isosorbide should never use Viagra due to the risk of dangerous blood pressure drops. Other contraindications include severe heart disease, recent heart attack or stroke within six months, severe liver impairment, and very low blood pressure. Men with hereditary degenerative retinal disorders or allergies to sildenafil should also avoid this medication. Drug interactions extend beyond nitrates to include riociguat and some alpha-blockers, making medical review essential before starting treatment.
Choosing Between Branded Viagra and Generic Sildenafil
Both branded Viagra and generic sildenafil contain the same active ingredient - sildenafil citrate - and work identically in treating erectile dysfunction. The primary differences lie in cost and manufacturer. Generic sildenafil typically offers significant cost savings while maintaining the same effectiveness and safety profile as branded Viagra. EverydayMeds provides both options, allowing patients to make their choice based on personal preference and budget considerations. Whether you choose branded Viagra or generic sildenafil, you'll receive the same clinical oversight and support from our UK-licensed healthcare team. The decision often comes down to individual preference, with some patients preferring the original branded medication while others opt for the more economical generic alternative.
