Viagra Safety Profile and Clinical Evidence
How Viagra Works and What to Expect
Viagra contains sildenafil citrate, a PDE5 inhibitor that increases blood flow to the penis during sexual arousal. It's important to understand that Viagra doesn't automatically cause erections - sexual stimulation is still required. The medication typically begins working within 30-60 minutes and its effects can last 4-6 hours, though this doesn't mean an erection will persist for this duration.
Clinical Safety Data
Extensive clinical trials involving over 4,000 men have demonstrated Viagra's safety profile when used as directed. The most common side effects are typically mild and include headaches (16% of users), flushing (10%), and nasal congestion (4%). These effects are generally temporary and resolve as the medication clears from the system. Serious adverse events are rare when the medication is used appropriately following proper medical assessment.
Realistic Expectations About Results
While many men ask about specific physical measurements, it's more important to focus on functional improvement. Clinical studies show that approximately 70% of men experience improved erectile function with Viagra. The degree of improvement varies between individuals and depends on factors including the underlying cause of ED, overall health, psychological factors, and proper usage. EverydayMeds ensures patients receive appropriate dosing guidance through our clinical assessment process.
Contraindications and Safety Considerations
Viagra isn't suitable for everyone. Men taking nitrate medications (such as GTN spray) must not use Viagra due to dangerous blood pressure interactions. Those with severe heart conditions, recent stroke or heart attack, severe liver problems, or very low blood pressure should avoid this medication. Our UK-licensed prescribers carefully review medical history and current medications during consultation to ensure safe prescribing.
Choosing Between Branded Viagra and Generic Sildenafil
EverydayMeds offers both branded Viagra and generic sildenafil options. Both contain the same active ingredient (sildenafil citrate) and work identically. The choice often comes down to personal preference and cost considerations. Generic sildenafil provides the same therapeutic benefits at a lower price point, while some patients prefer the branded version. Our clinical team can help you decide which option best suits your needs following assessment.
Dosage and Safe Usage Guidelines
Viagra is available in 25mg, 50mg, and 100mg strengths. Most men start with 50mg, taken approximately one hour before sexual activity. The dose may be adjusted based on effectiveness and tolerability, but should never exceed 100mg in 24 hours. Taking Viagra with fatty meals may delay its onset of action. Alcohol should be limited as it can reduce the medication's effectiveness and increase the risk of side effects.
