Comparing Sildenafil and Viagra: The Complete Guide
Understanding the Difference Between Sildenafil and Viagra
The primary difference between sildenafil and Viagra lies in branding and cost, not effectiveness. Viagra is the original branded medication manufactured by Pfizer, whilst sildenafil represents the generic equivalent containing the same active ingredient - sildenafil citrate. Both medications work identically by inhibiting the PDE5 enzyme, which increases blood flow to the penis during sexual arousal.
From a clinical perspective, there is no difference in how these medications perform. The Medicines and Healthcare products Regulatory Agency (MHRA) requires generic medications to demonstrate bioequivalence to their branded counterparts, ensuring identical therapeutic effects. This means sildenafil provides the same onset time (30-60 minutes), duration of action (4-6 hours), and success rates as Viagra.
Cost Comparison: Why Sildenafil Offers Better Value
Generic sildenafil typically costs 80-90% less than branded Viagra, making it significantly more affordable for long-term treatment. This substantial cost difference occurs because generic manufacturers don't bear the research and development costs associated with the original medication. Once Pfizer's patent expired, other pharmaceutical companies could produce sildenafil at much lower prices whilst maintaining the same quality standards.
For men requiring regular ED treatment, choosing sildenafil over Viagra can result in annual savings of hundreds of pounds. At EverydayMeds, we offer both options at checkout, allowing patients to select based on their personal preference and budget considerations.
Clinical Effectiveness and Safety Profile
Both sildenafil and Viagra demonstrate identical clinical effectiveness rates, with approximately 70-85% of men experiencing improved erectile function. The medications share the same safety profile, contraindications, and potential side effects. Common side effects may include headache, flushing, nasal congestion, and indigestion, typically mild and temporary.
Neither medication should be taken with nitrates (such as GTN spray), as this combination can cause dangerous drops in blood pressure. Men with certain cardiovascular conditions, severe liver impairment, or recent heart attack or stroke may not be suitable candidates for either medication. Our clinical assessment process evaluates these factors regardless of whether you choose sildenafil or Viagra.
Dosage Options and Treatment Flexibility
Both medications are available in identical strengths: 25mg, 50mg, and 100mg tablets. The starting dose is typically 50mg, taken 30-60 minutes before sexual activity. Depending on effectiveness and tolerability, the dose may be adjusted to 25mg (if side effects occur) or increased to 100mg (if 50mg proves insufficient). The maximum frequency remains one dose per 24-hour period for both options.
Food intake affects both medications similarly - fatty meals may delay onset of action, so taking either on an empty stomach or after a light meal optimises effectiveness. Neither medication causes automatic erections; sexual stimulation remains necessary for the medication to work.
Prescription Requirements and Accessibility
Both sildenafil and Viagra are prescription-only medicines (POM) in the UK, requiring consultation with a qualified prescriber. EverydayMeds provides convenient online consultations with UK-licensed clinicians who assess your medical history, current medications, and suitability for treatment. This process ensures safe prescribing whilst maintaining patient privacy and convenience.
The consultation covers essential health factors including cardiovascular status, blood pressure medications, and potential drug interactions. Men taking nitrates for heart conditions or certain blood pressure medications may not be suitable candidates for either sildenafil or Viagra.
