Who Can Safely Take Viagra for Erectile Dysfunction?
Understanding Viagra's Effects on Sexual Duration
Viagra (sildenafil citrate) is a PDE5 inhibitor that increases blood flow to the penis when sexually aroused. Whilst it doesn't directly extend sexual duration, many men report lasting longer due to improved confidence and reduced performance anxiety. The medication's effects can last 4-6 hours, providing a window of opportunity rather than prolonged activity.
Clinical Eligibility Requirements
To take Viagra safely, men must meet specific criteria. You must be 18 or older with diagnosed erectile dysfunction. A UK-licensed prescriber will assess your cardiovascular health, current medications, and medical history through a clinical consultation. This assessment ensures the medication is appropriate for your individual circumstances.
Who Cannot Take Viagra
Certain medical conditions and medications make Viagra unsuitable. Men taking nitrates (GTN spray, isosorbide) face dangerous interactions that can cause life-threatening drops in blood pressure. Those with severe heart disease, recent heart attack or stroke within six months, severe liver impairment, or very low blood pressure should not use sildenafil.
Important Drug Interactions
Viagra interacts with several medications beyond nitrates. Alpha-blockers used for prostate problems may require dosage adjustments. Some antifungal medications, certain antibiotics, and HIV protease inhibitors can affect how your body processes sildenafil. Always disclose all medications during your consultation.
Branded vs Generic Options
EverydayMeds offers both Viagra (branded) and sildenafil (generic) at checkout. Both contain the same active ingredient - sildenafil citrate - and work identically. The generic version typically costs less whilst providing equivalent effectiveness. Your choice depends on personal preference and budget considerations.
Dosage and Administration
Sildenafil is available in 25mg, 50mg, and 100mg strengths. Most men start with 50mg, taken 30-60 minutes before sexual activity. The dose may be adjusted based on effectiveness and any side effects experienced. Only one dose should be taken per 24-hour period, and fatty meals can delay the medication's onset.
Managing Expectations
Viagra requires sexual stimulation to work effectively - it doesn't cause automatic erections. The medication may help you feel more confident, potentially leading to improved sexual performance and perceived longer duration. However, it's not specifically designed as a treatment for premature ejaculation, which requires different therapeutic approaches.
